Price drop!!!

[ATIS]

Horizon Hobby has dropped the price on a few airplanes to include the PT-19, Talyorcraft, MUS, and a few others!! Time to stock up on those winter builds and expand your hangars!! :clapping::happy bounce:

[WJCJR1]

Thanks ATIS!

[ATIS]

no problem... the MUS has been on my list for a while...may have to pick her up. I maidened a friends a few weeks back and she flys great and on a 480 makes a fast sport aerobatic plane...right up my avenue for a fun day of flying.

[max2112]

Wow! Those are very tempting!!

Man, I wish that I was independantly wealthy!

Thanks much for the heads up.

[ATIS]

No problem... planes I would look to get are the PT-19, RV-9 and the MUS from the price drop. All are great flyers and are very capable on EFlite 480 (1020kv) motors on a 3s 2100 lipo.

Great... just great!

Man, it’s hard to hold onto any money around this place!!


Every time I login here there’s a new review
I’ve got a $130.00 sitting in PayPal
Horizon Hobby just sent me a Happy Birthday coupon for $10.00.

And now this!

I'm guessing the PT-19 would be a good first wooden ARF for someone like me who has only flown foamies (Apprentice, Mustang and Sea Fury).

I have everything in stock that I would need to complete her.
.

[ATIS]

Either the PT-19 or the RV-9 would make a good first balsa. The RV-9 has flaps and is more "sporty" were the PT-19 flys great and is more scale. Both loop and roll and slow well for landings but the RV-9 wins on faster roll rate and stall turns with its begger rudder.

Dont feel too bad, my wallet is hurting as well since I buy all the planes I review... 3 more coming out later this month!! Ouch...on a side not, my back wont hurt from sitting on my wallet... it will be so thin I wont notice it!

[tkrahlin]

...my back wont hurt from sitting on my wallet... it will be so thin I wont notice it!

Well, I’m now the proud owner of a PT-19 ARF ($119.99).

I printed the PT-19 page from Horizon’s web site and took it and the $10 birthday coupon to my LHS.
The store put in a call to HH and found that their new pricing will start next Wednesday, so they matched HH’s online price and honored the coupon.

[ATIS]

sweet!!!

[kirch]

So I guess happy birthday is in order?

Please let us know how the maiden flight goes. That PT-19 is so nice looking.

So many planes .. so little money. I am more than happy with my T-28D right now as it is capable of doing much more than I can fly right now.

It is that scale vs performance trade-off that is always challenging in picking a next plane. Anybody know how the PT-19 flies off of grass?

[ATIS]

Check out the review on her in the articles section . I fly off of grass. She flys great off of it.

[tkrahlin]

So I guess happy birthday is in order?

Thanks!

Is this where I post a link to my Horizon Hobby Wish List… or should I just start a whole new thread? ::tonguee:


And more importantly, would it matter? :-)

[dbcisco]

Happy Birthday tkrahlin !

[kirch]

I think our wish list is the contents of ATIS's hangar .. seems to have almost every plane one could want... at least the ones that have been released already.

[ATIS]

thanks guys... thats what your garage will look like when you get to the point of rarely crashing/improve repair skills and have been doing this for a few years (it also helps to only put RC planes on your Christmas and Birthday wish lists :) )

[WJCJR1]

Tim getting a little prepunctual with the Birthday there huh, Mr. Sept.21... So when the day does arrive in a couple and a half weeks maybe the birthday gift gifter may have forgotten about this gift and another plane may be in order.

If this is so, good thinking. If not, see if you can pull it off! ::very happy::

With that having been said I will wait to wish you H.B. till 9/21 and maybe you'll have another plane to celebrate with.

I am sure you'll love the PT-19 and unlike the SeaFury it'll be around for a while so no parts obsolesence to deal with. Good choice and I look forward to hearing how it all goes together and flies for you.

I think the trick is to get rid of the old boxes as you bring a new one in.

To the undiscerning eye, it’s all just a box count and the space they take up. If I can give the appearance that the clutter is not expanding, I think I can make it all the way to, “Is that a new plane?” halfway through the build.

By then – if I’m living right – it’ll be the 21st or better and the new ME109s will be in the stores.

::tonguee:-:p-:o

[WJCJR1]

Good job!

Wayne

[herk1]

Wow, that RV-9 looks nice, priced right, good big size (but I could still use my existing batteries) and looks like it might be a good home for that Scorpion motor I still have lying around that my Trojan didn't like. And working flaps! Except it's a tail-dragger and I prefer trike. Hmmmm....decisions...

tkrahlin - Let me guess...the LHS you're getting the PT-19 from is...um...HobbyTown USA out on the east side of town? (used to be located on the north side) I've bought lots of stuff there. I'm down near DCRC club field. Our birthdays are close too...that Super Airliner I spoke of is going to be my birthday present.

[tkrahlin]

Materials On Hand (definitely ex-military!) :thumbsup:


tkrahlin - Let me guess...the LHS you're getting the PT-19 from is...um...HobbyTown USA out on the east side of town?

Bingo! With one correction: The PT-19 is already here just a few feet from me. Yeah, I was the youngest of four children - why do you ask?

Btw, in a scale back / cost cutting measure, HobbyTown USA let Eric go. If you know of whom I speak, you know he will be missed.

I finally got started on the PT-19 build and finished the wings last evening.

Being my first wooden plane some of this is new territory for me, yet much of it is straightforward modeling. One of the things I think we all agree on is that building is as much fun as flying. I can see after just one evening that when working with wood and Ultrakote a heightened focus to detail and care rewards you with a very nice product.

[tkrahlin]

About 30-minutes after I posted the previous message, I poked a hole in the Ultrakote with the Phillips screwdriver.

It's in the bottom of the wing right next to the main gear bracket - small enough that I’d have to point it out to you, but big enough for me to know it’s there.

I have a piece of scotch tape over it now to keep it from tearing.

I can’t be the first one to do this -- What’s a nice clean method of repair?

If I could get to the other side, I could just fold the hole back into place and tape it from both sides. I don’t have any Ultrakote nor do I have any experience with it. Maybe if I could match the paint, (I’d need a dot), the scotch tape would suffice.

Thanks,
Tim

[ATIS]

did you save the pieces from when you removed them to glue the control horns down? You can use them to cover the hole... I drilled my aelrion holes too deep on one side and came through the covering and thats how I fixed them. Barely noticable on the ground, cant be seen at all in the air.

I didn't have to screw or glue any of the horns - they all came pre-installed. I do however have two 1-inch wide strips of blue. I'll just leave it with the piece of clear tape for now.

Btw, she's all done and is a sweet looking airplane.

And I got some prop numbers:

Park-450
30-amp Eflite ESC

APC 11x7e
2250mAh x 30c
240 watts @ 20-amps

APC 12x8e
2250mAh x 30c
274 @ 23-amps

[WJCJR1]

I remember ATIS said he felt HH under-rated their products but just be aware from HH website:

Park 450 Brushless Outrunner Motor, 890Kv by E-flite (http://www.horizonrcflyers.com/Stores/Default.aspx?StoreBrandId=EFL), EFLM1400
Continuous Current:14A
Maximum Burst Current:18A for 15 seconds

Not sure if the Park450 is what you were referencing but just a FYI.

I have been very careful not to be exceeding the specs on my motors. I use them right to their rated limit but then that's it. I have been tempted to cross the line but then think otherwise as this can be an expensive mistake.

Any pictures of your new plane? When is maiden?

Glad you are having fun building, learning and expanding.

Wayne

[ATIS]

Tim, the recommended prop on the 450 motor is a 10x8.... if you really want the 11 inch prop I would suggest a APC 11x5.5E prop to drop the amps (even if its only 1 or 2 amps)... the motors can take a little more then whats listed but your pushing it with those props. 20amps at WOT means that to get under the 18 amp burst your going to have to go down to 1/2 throttle and stay there for extended periods of time plus you will need good cooling. Remember when I reviewed this plane I used the EFlite 480 (1020kv) and she is rated for more amps. Smoking the motor and not the ESC would at least leave you with servo control, however without power she will need to be trimmed well and she has a good glide ratio if the CG is set correctly but I wouldnt want to try and turn and set up for a landing without power if I didnt have to.

The maiden was about 2-hours ago.

She wouldn't even roll on the bomb crater grass field at the school, but she ROG'd like full scale off the parking lot. Trim was nearly dead on, climbed at full throttle, but flew nice and level at about 65%.

Flew about 15-minutes, aced a couple or three landings on the hardtop and went for a second battery. A few circuits and a couple landings later then it happened...

I wing stalled her in a turn and didn't have enough room to recover.

Now it's firewood.

Man, I gotta tell ya... this one REALLY hurt. There's something about the look of splintered wood that just seems to burn itself on the back of your eyes.

RX, esc, motor and servos are all good.

I just picked up a pizza and I'm heading to the tub with some cold beers.

[CLSSY56]

Does your TX have a glitch or something? You've lost more planes than I care to remember. Sorry to hear it bud.

Tim that stinks man! From what I see above your build was a successful one until the accident.

Is it safe to assume the CG spot on or were you potentially aft heavy a bit. Aft heavy set-ups make for easier/faster corner stalls if going too slow. For that matter, were you in a tight area acreage wise having to bank steep and slow?

All is not lost, your earlier post statements suggest you were learning a lot abut wood-building and covering characteristics. Also play this back in your mind and see if you can figure out what happened and learn from it. You are very familiar with your 25 powered Apprentice, get her out and see if you can make the same tip stall occurr, then you'll know what caused it. All joking aside do it at a safer altitude. Better yet see if you can mimic it on a simulator.

My gut guess, and this could be way off, you were aft heavy and/or banking at a very slow speed and the plane lost lift and she turned (snapped) in spiraled down end of story.

Once more sorry to hear of the loss but for sure you will have grown in piloting experience by being able to diagnose, register the symptoms of a stalling plane or how to not get into that scenario in the first place.

Thank-You for sharing your build, first thoughts and unfortunately the accident with us.

Wayne

[ATIS]

Tim,

Sorry about the lose, how did she fly before the tip stall (which surprises me with the low wing loading)?

[tkrahlin]

Wayne

It’s almost as if you were there.

“…banking at a very slow speed and the plane lost lift and she turned (snapped) in spiraled down end of story.”

Yeah – snapped was more like it. The worse part is, I had been flying the PT-19 on Real Flight and I’ve seen how easily it can drop.

Flight setup:

Park-450
APC 12x8e
2250mAh x 30c
274 @ 23-amps

The battery at 180 grams was all the way forward. Thinking back now that only put the plane slightly nose down - but not the nose heavy configuration I like to fly.

And you’re right – she was flying nice, but I noticed right away that she doesn’t like to be slow. This worried me a little thinking about having to land her. However, I was really relieved to see how nice she settled in by reducing the throttle, throwing a few clicks of down elevator and just steering her in. Reading that now as I type it, it sounds like a neutral CG plane, doesn’t it.

I also mentioned that she climbed on her own when I went full throttle, but flew level at about 60-75%.

Now, as if that’s not bad enough, I can’t just cut my loses and walk away. Please tell me it’s not just me that does this, but I have to get another one.

[ATIS]

I am on my 3rd EFlite AT-6 (currently fixing the 3rd...again)

I’ve never been one to derive pleasure from others’ misfortune. I will however, admit to taking some comfort in hearing that... sorry.

Besides! I know what I did wrong and it will never happen again… ;)


I think I'm going to print this and tape it to my tx.
"Lose not thy airspeed, lest the ground rise up and smite thee."

[tkrahlin]

Hey - all kidding aside. I stopped by the LHS and there are no more PT-19s in stock... "we can order one for 'ya" - yeah well, so can I.

But, they do have an RV9 AND a Park-480 AND a CC ESC.

I couldn't be sure, because it was inside the showcase, but I thought I could hear the 480 saying, "PICK ME, PICK ME. Take me home."

[WJCJR1]

No mention of CG check Tim, did you check this? If a plane FLOATS in real long on approach and needs down input to bring her in that can be a sign of a tail heavy plane, the angle of attack on the wing being changed just a little from being tail heavy can cause the wing to 'kite' the plane. Just saying.

You remember when I destroyed mu Supered up T-28D, I had a new fuse, horizontal, wing, cowling, motor mount, servo arms and had her completely rebuilt by 1:30am the next morning, flying by 10:00ish the next day. This tells me you really liked the plane's charcteristics and that you want to try again.

I have only "snapped-in", "spiraled", "dropped a wing" once during a bank and thankfully I had just enough altitude to drop, level, gain airspeed and recover. I have seince then been much more attentive of this potential side effect of low air speed especially cornering.

Wayne

[tkrahlin]

No mention of CG check Tim, did you check this? Wayne

Oh yeah; I checked it at home, but I was concerned that the sticks of my homemade my CG machine might poke the Ultrakote so I used my fingers.

"The battery at 180 grams was all the way forward. Thinking back now that only put the plane slightly nose down - but not the nose heavy configuration I like to fly."

My "slightly nose down" on the fingers may well have shown up as a neutral CG on the sticks.

Besides the velcro strap, I put velcro on the floor and the bottom of the battery. There's also a chance the second battery didn't go all the way forward. Through the next time I saw it, it certainly was all the way forward.

Btw, the battery is a Thunderpower 2250 x 30c. I've spent the day charging/balancing it then discharging it and charging/balancing it again just to be sure. Everything seem just fine with it.

Tim

[ATIS]

was that slightly nose down balanced INVERTED? Low wing planes have to be balanced inverted. I always use my fingers. Make sure they are on the marks and the nose is down 2-3 degrees below level (you get better at "seeing" this as you get more experience).

After you get the lipo set up for the CG and get here flown. If all is well after the flight, I use a marker to draw a line along the batteries top edge on the wood so I can just install the lipo and fly without having to balance her again.

On a side note Tim, I lost all 3 AT-6's to tip stalls...

[tkrahlin]

I went back to the LHS on Monday and ordered another PT-19...

I guess it's like being thrown off of a horse, huh?

Tim

[ATIS]

The difference is the PT-19 is better tempered then the horse...keep yur airspeed up. No planes like evasive manuevers at low speeds.

[tkrahlin]

The difference is the PT-19 is better tempered then the horse...

And easier to clean up after...

.

[WJCJR1]

And easier to clean up after...


Especially if all the cleaning needed is dusting off the bugs you whacked in the air.

Now if you have to pick up tooth-picks again you may wish it was a bit of horse poop instead.

Get her a bit nose heavy, do as ATIS said and I am sure you know keep the speed up in especially in the corners. Remember to command the landing as well stalling on that landing isn't any good either, especially the more fragile woodies.

Wayne

[tkrahlin]

Haa-he-uhhh, he said woodies.

Here's the copy of the text HH posted on their Facebook page about the sale.


Horizon Hobby: Over 50 Hangar 9 and E-flite planes have dropped their prices! Check them all out here! http://search.horizonhobby.com/index.jsp?N=0&Ntt=hangar9_e-flite&sid=1240D861D1A6

[ATIS]

nice selection:

Mini Ultra Stick
PT-19
RV-9
PT-17
Mini Pulse

all good choices....

[tkrahlin]

I finally got to start on my [second] PT-19 today. If there's a bright side, it's that the build goes quicker the second time. All I have left to do is mount and hook up the motor, secure the wings and route and plug in the wiring.

The only servo that didn't survive the crash was the rudder servo... it was cranked all the way over in spin recovery and stripped the gears.

[tkrahlin]

The only change I made to my second PT-19 is that I switched to a 36-amp Castle Creations Thunderbird ESC --- the same one I'm running in my THIRD Mustang.

I sent three RXs to Horizon – two were from the first two totaled Mustangs. The third was from my third Mustang before I even flew it. They tested them and said they were all good, but sent me back three brand spanking new radios ‘for my peace of mind.”


My first EFLite PT-19 ARF got one of the new radios in it. That plane is totaled.

Before I flew the third Mustang, I put in one of the new AR500 radios that Horizon sent me. However, I used a 36-amp Castle Creations Thunderbird ESC. I also outfitted her with a Park-480 motor spinning an APC 11x7e prop. The only problem I’ve had with her is keeping her in the same zip code.

Of all the planes I built, I currently have three survivors:
An Apprentice with a Power-25 motor and a Castle Creations Phoenix-45 ESC.
The Mustang with the Park-480 and a 36-amp Castle Creations Thunderbird ESC.
An EFLite Sea Fury with a Park-450 and an EFLite 30-amp ESC, but with a 10-amp Castle Creations BEC.

I don't know what to make of all this, but the T-Bird ESCs are relatively inexpensive.

[tkrahlin]

I just got back from the maiden flight of my [second] PT-19.

She flies like a dream… just keep the speed up and make sure those turns are coordinated, especially when slow.

On this plane, I put the Castle Creations 36-amp Thunderbird ESC in the basement under the battery tray and added one piece of lead inside the cowl.

I flew three batteries through her without one problem or scary moment in the air. However, I did come away with a touch of runway rash on the wingtips (the downside to landing on hardtop). It’s hardly noticeable, but I worry that the Ultrakote may peel back. My gut tells me something like clear nail polish (maybe thinned a little). Any suggestions?

After the third battery and about 8-10 landings, I taxied back and parked her. Then I broke out the Sea Fury and put four batteries through her.

I had a few more batteries, but the winds started to increase and come from different directions – I hate it when that happens.

The last takeoff with the Sea Fury was into a gust and she ballooned up into the air, porpoise’d and came back to within inches of the ground. Picture me standing in the middle of this parking lot, talking myself through this – “Come on… you can make this happen!!” Like the man says, “Never Stop Flying The Plane.”

I learned a new term at Flight School, “Aeronautical Decision Making.” It’s goes bah-bah-bah, but simply put, it means put the machismo on hold and know when not to fly in conditions above your skills or that of the aircraft.
I still got in about two hours of flying and brought both planes both back in one piece.

[ATIS]

Congrats!! Happy to hear she is in one piece and she flys better then the last one.

[WJCJR1]

Good job Tim, hey if you got the chance start a flight log. Looking forward to seeing more on your REAL flight training.
