Twin Cities IMAC Classic

[Jason D]

The third annual Twin Cities IMAC Classic is scheduled for June 12-13 at Tri-Valley in Rosemount, Minnesota.

For those of you not familiar, IMAC is the International Miniature Aerobatic Club, a SIG of the AMA.

This event is competitive Scale Aerobatics. Some of the better pilots in the upper midwest will be in attendance from Minnesota, Wisconsin, Iowa, Illinois and maybe even Indiana.

These events are a lot of fun to watch and even more fun to participate in.

Please let me know if you are interested or would like additional information.

Hey Jason as we had spoke last year I'm in. I am not the pilot I need to be to win something but I'll come, participate and document you bringing home the bacon.

The Deuces Wild will fit in nicely I would think.

Talk soon,
Wayne

[Jason D]

That's great, Wayne. At some point here this spring I am going to go down to Tri-Valley for a day of practice. You and Ethan should come with. It's a bit of a drive, but it is a really nice field.

-Jason

[Jason D]

Wayne,
I just reviewed the rules and unfortunately, your airframe can only have 1 propeller according to rule 4.1.

I did apply for, and received a waiver so that we will not be 'Ground Sound Level Testing' - Rule 5.3

Here is a link to the current rules:

http://www.modelaircraft.org/files/ScaleAerobatics2010.pdf

[WJCJR1]

WHAT! I need two propellers to have any chance of keeping up with you guys, at that it's a long shot. ::yell::

Any chance of a freestyle entry?

Wayne

[Jason D]

Wait a second, here...

Rule 3.2 states that the Basic Class is open to any competitor with monoplane or biplane. So you may be ok with the Dueces' Wild.

I am going to say that you would be OK, but I'll do some further investigation.

Yes, there are a couple people already signed up for the freestyle. We'll probably have the freestyle part of the event on Saturday evening after the sequence rounds are done - weather and time permitting.

[Jason D]

This year's TCIC is this weekend! It is a lot of fun to spectate, but a lot more fun to participate.

Come one, come all.

Come one, come all.

Jason and I will be meeting up Saturday in Rosemount for the Twin Cities IMAC Classic.

Jason is a very good precision pilot whome placed extrememly well in his multi-state region.

I declare although I can hold my own wing I am no-where near the pilot Jason is and do not pretend anything different. I will be entering the Basic Class Competition and look forward to having some fun, learning some and of course getting some air under my wings. I will be using the E-Flite Deuces Wild as my airplane, hopefully I don't stick out like a sore thumb too badly.

We will be getting some photos and videos and look forward to sharing the experience with everyone!

Wayne

[Jason D]

Wayne,
I can't tell you how pleased I am that you are going to give IMAC a try. I really admire pilots who are willing to step out of their comfort zone and give something like competitive aerobatics a try. Below are some links to information that you may find useful, I encourage everyone else to take a look and consider giving IMAC a shot. A better group of like-minded individuals you will not find.

[WJCJR1]

Thanks for the great information Jason, helpful to me it is.

Most the aerobatics within the program are normal everyday flying. What will be new is the fact I will be doing it in a regimen rather than just from the hip.

Wayne

[WJCJR1]

JRB,
JasonD and I will both be at IMAC this weekend. Tri Valley is hosting, will you be on site, flying?

Wayne

[WJCJR1]

JRB it was good to meet you today and an honor to fly at Tri-Valley, that is a gem of a facility. I had no trouble settling in with that beautiful, 600+ FT Long, Tar, Flat, Smooth inviting runway. In addition the VERY open approaches to the runway are great!

So THANK-YOU to Tri-Valley Airfield for hosting the Twin Cities IMAC Classic.

BTW your Toledo flew well too.

I missed you at IMAC competition time were you still on site or had you left? Did you see my one engine landing of the Deuces, that was on my first feeling out screwing around flight with the Deuces Wild. I knew something was WRONG when she began pulling to the side and losing power, I accidentally screwed up my timer and flew 4:30 too long. I was suposed to land at +3:00 but ran to -1:52. So I flew the Deuces Wild that time for 13:00! When she hit LVC on the motor that runs the Receiver I knew something was wrong, still got in a nice landing though.

Man I can't get over that REAL nice runway.

Wayne

[WJCJR1]

IMAC Twin Cities Classic was a great time today. Unfortunately we were dodging rain and low ceilings all day. We probably wasted too much time in the morning waiting for the rain to come and go but the ceiling was just too low anyway for the advanced and unlimited classes.

I had the pleasure of meeting several sponsored full-time circuit pilots and enjoyed the extra time we spent in the rain shelter talking and hearing plane stories. I got to fly 2 scored competition flights with the Deuces. The eyebrows were raising when it was heard I was flying an electric and at the end of the day I was receiving compliments on how well the Deuces Wild flew and that most of the time electrics are overlooked at these events but the Deuces fit in well. There are two judges that score each event I only received 12 perfect scores (scoring 1-10 by IMAC judges) today and that was for the sound level of the Deuces Wild and Airspace Control. Out of 96 scores I received 8 zeros for maneuvers not performed properly and then 9 other scores below 5. There are 10 sequences that you must fly and then do it again so there are 20 aerobatic maneuvers per competition round that you have to do in order one after another. Each maneuver gets a score from each judge and then a score from sound and score for Airspace Control. So each Round you have 48 scores. I found the pressure got to me a couple times as most of these maneuvers I have done just fine before but when I wanted to do them and where and both those elements are chosen for you. Add into this the element of rain on my first round so water on my glasses and then the extremely low cloud deck sub 350' I am happy as heck.

I had a terrific time and would encourage EVERYONE to go try one of these events. I LEARNED A LOT today. The Deuces Wild is WAY more agile than I had ever thought now that I was forced to stall it and spin it and more today. Also watching the other pilots fly the course was educational to say the least. The couple JR guys were very helpful, well everyone was very helpful. Unfortunately due to the weather the turnout was VERY low with only 9 registered pilots, close to half of those pilots were the travelling guys. I overheard the event director there were more than twice that already registered that didn't show due to the weather. I don't blame them the weather was crud.

I have a few pictures, only 4 maybe 5 of us flew so not many opportunities and nobody videod or photo'd me so only 3 or 4 others flew so the opportunities were less than overwhelming. I'll get some pictures, the one video I have of a round of sequences being flown and more about my experiences on my flights in my flight log.

Wayne

[wgeffon]

Wayne,

Nice meeting you today.
Glad your giving IMAC a try. Keep at it and you will do real well.

If anyone reading this hasnt seen these, I made video recordings of all the 2010 sequences. If your not sure what something is supposed to look like, watch these videos.

[WJCJR1]

Nice tutorial video Wayne, I looked at the Basic Class Sequence. For some reason mine didn't look exactly like the video you put together ::tonguee:

I wish I was able to see you more advanced guys fly today but as we discussed when planning by the calendar, which well we all have to do, the weather will be what it is. I thought we made the best of it though and squeezed in what we could in the afternoon in-between dodging rain and rolls of thunder. JasonD was really bummed as he was expecting a turnout more like last year from what I heard it was very busy. In a way though I am glad I was able to experience the slower activity of the empty field, flying two competitors at once would have been another challenge.

Wayne

[jrb]

Nice to meet you too Wayne -- hope you thought the drive was worth it.

You've got an open invitation from me and we've got our Spet MARCEE meeting -- the'd be 2 more visits!

IIRC one of the MARCEE members maiden hiw DW w/retracts @ TVRC during our meeting last year. Its a great place to maiden advanced and fast planes; i.e. turbines!

Left at the time th feild was closed to open flying; needed to get some wifey time in too.

Is there more competition today; will you bee there?

Thanks for posting the video link wgeffon; can I download call cards from someplace.

Jim

[WJCJR1]

You can download call cards from Jason's links here: http://www.horizonrcflyers.com/forums/showpost.php?p=11351&postcount=10

They are very helpful in giving you a fun sequence to run and a challange as well.

Wayne

[jrb]

Thanks; missed them the 1st time around.

Just learned the Aeros are scale; the model need not be -- but not more than one prop.

[WJCJR1]

The not more than one prop is not in the rules, JasonD thought it might have been but it turned out it was not.

If it were to have been I wouldn't have been able to compete.

Unfortunately I just wrote a LONG/EXPANDED Flight-Log here describing the IMAC day yesterday in detail, it was a thing of beauty a dissertation. Unfortuantely when I hit submit reply I did nto copy it and somehow someway it got lost from some token error. GRRrrrrrrrrrr:mad:!

I will post my Score Cards here in a minute, try to get some photos up and then do the 'dissertation' again later.

Wayne

[jrb]

Ok; copy & paste from Word works well for long/detailed posts:

[WJCJR1]

I will try that next time. Good tip!

I read your post there about one propeller per aircraft, I will have JasonD, and/or WGeffon comment. I wonder if that is a rule pertaining to a certian Class. The IMAC directors all yesterday said it was not an issue. So if you have a twin you'd like to fly I wouldn't hesitate, ask to be sure but from what I was told and being allowed to fully participate no worries.

Wayne

[WJCJR1]

There is no preferential scoring for newbies to IMAC so where I deserved it I got hammered. I would say the scoring was very much how I would've critically evaluated my performance.

The Deuces Wild is capable of answering all these maneuvers with 10's. My trimming not being precision accurate, thrust angles maybe not being perfect and my lack of Rudder experience/competence led to some long vertical lines that were a little askew from a cross-breeze especially at altitude. Inverted 45* angle going away rudder cross-wind correction on the Reverse Shark's tooth got me every time a couple times pretty good but mostly just ooops I went right when I wanted left.

The judges are humans and not machines and did not agree in all areas when comparing scores. On the scorecards you'll see the maneuver names, then NOTE: I received on all 4 scorecards perfect 10's for sound level! :clapping: I was told I'd likely receive a perfect score for that!

One gas plane received a full 10 as well I thought I saw. There was some contention between judges I heard them debating, civilly but spiritedly how a gas plane much louder then this electric can score the same. The scoring system has some interesting flares to it. All I know is I am glad I did not need to judge as the judging appeared as demanding as flying the darn plane.

Maybe the DW is OK based on this and the CD’s approval?
3.2: All classes except Basic require that the pilot must meet the requirements defined in Rule 3.1. The Basic Class is open to all competitors with a monoplane or biplane aircraft. There is no minimum size requirement for any class. Contest Directors may make an exception for a model of a full scale aircraft that was built for IAC competition, but has not yet competed. Proof of the latter is the responsibility of the contestant.

Might change contest to contest?

Actually it looks like anything beyond Basic requires a Scale Model
3.1: The events accommodate aerobatic monoplanes and biplanes which are replicas of types known to have competed in International Aerobatic Club (IAC) competition, or replicas of types known to be capable of aerobatic competition within the airspace know as the ―Box.

[WJCJR1]

Yes Jim that is exactly it, I received a response back from Jason D as him and Wayne G had discussed this issue:


Wayne,
Wayne G. and I talked about this beforehand. Rule 3.2 supercedes it - "...The Basic Class is open to all competitors with a monoplane or biplane aircraft..."

-Jason


So fear not if you have something you'd like to fly in the Basic Class let her RIP!

Wayne

[WJCJR1]

I'm getting photos to upload ok today. Think I was uploading just too large of files, never been a major issue today but well computers have never been my specialty.

As you can see in the below photos some pretty dark weather.

Let's ask, PM sent to Jason D and wGreffon to clarify plainly.

Wayne

[wgeffon]

Good meeting you this weekend Wayne.


CD's do not have the abaility to just make up stuff as they go.
Every IMAC contest is run the same way no matter where you are. They are run under current AMA regulations for Scale Aerobatics.
A CD may apply for a Waiver on any rule but, that waiver must be submitted, approved and posted no later than 30 days prior to the event.

Jason and Any did have one waiver for this contest.
They elected to not conduct On Ground Sound testing.

Hi Greg!

Just a quick question – can a twin be flown in IMAC Basic?

TIA,

Jjrb8

[Jason D]

Twin Cities IMAC Challenge Contest Report:

First of all I'd like to thank the people that helped out this weekend - specifically, Andy Thomas - contest coordinator and Wayne Geffon - contest scorer. I'd also like to extend a big thanks to Smartfly, who continues their support of IMAC contests.

Some of you probably know we had some pretty crappy weather this weekend. That and quite a few people who normally attend had more pressing issues so our attendance was way down.

We pressed on, though, and I hope that those that were there had a good time.

Overall, there were 9 pilots flying in the Twin Cities IMAC Challenge contest. In no particular order they were: Andy Thomas, Terry Foster, Jerry Ream, Jason Dumke, Allan Stenroos, Wayne Geffon, Dan Knippen, Dave Willmott and Wayne Croteau. These pilots flew a grand total of 92 judged sequences.

This contest was flown according to modified rules.

Jerry Ream won the Basic class. There were 3 pilots in Basic. The winning order was: (1) Jerry Ream, (2) Terry Foster and (3) Wayne Croteau. They flew 6 known sequences (3 rounds). The scores ranged from a low of 2,481.7 to a high of 4,000 (a range of 1,518.3 points).

Allan Stenroos won the Sportsman class. There was 1 pilot in Sportsman. The winning order was: (1) Allan Stenroos. He flew 6 known sequences (3 rounds).

Dave Willmott won the Intermediate class. There was 1 pilot in Intermediate. The winning order was: (1) Dave Willmott. He flew 6 known sequences (3 rounds).

Andy Thomas won the Advanced class. There were 2 pilots in Advanced. The winning order was: (1) Andy Thomas and (2) Jason Dumke. They flew 4 known sequences (2 rounds). The scores ranged from a low of 2,921.9 to a high of 2,950.6 (a range of 28.6 points).

Wayne Geffon won the Unlimited class. There were 2 pilots in Unlimited. The winning order was: (1) Wayne Geffon and (2) Dan Knippen. They flew 4 known sequences (2 rounds). The scores ranged from a low of 1,862.6 to a high of 3,000 (a range of 1,137.4 points).

In addition to the standard classes, there was 1 special class: Seniors.

Dan Knippen won the Seniors class. There was 1 pilot in Seniors. The winning order was: (1) Dan Knippen. He flew 4 known sequences (2 rounds).
The tightest competition was for 1st place in the Advanced class, with only 28.612 points difference between Andy Thomas and Jason Dumke.

The venue for next year's event will likely change for a couple reasons: First, we seemed to have topped out as far as local participation is concerned. Second, we don't get a lot of club support, and I'd like to find a club that could provide a little more. Third, we are likely going to lose the current field next year (No, it has nothing to do with loud IMAC planes).

Everyone, flew really well this year and quite a few of us are planning on making some more events later this summer.

Thanks again, everyone.

Wayne - I have your 3rd Place award. If you are going to be at the field this weekend, I'll bring it with.

[jrb]

I'm not really sure what you are getting at...WC was in the Basic class.

Saw this after I posted; guess we crossed in the ether somewhere.

Run what you brung in Basic sounds great to me!

[WJCJR1]

3rd out of 3 WAHOOOOooooo! I'll try to make it, send you a PM or call you alter this week.

Thank-You Jason for the thorough wrap up and synopsis.

Wayne

[WJCJR1]

What is the question?

In your Private Messages box you'll have a message about the rules pertaining to the DW's eligibility. You answered the question thoroughly already so thanks!

Wayne

[Jason D]

Run what you brung in Basic sounds great to me!

Yeah, that's exactly why that rule is in place - to get new people interested by giving them a chance to compete without having to purchase specialized equipment.

The great thing is that this is an extremely effective way to promote this part of the hobby. Over the years I've seen multiple people give it a shot, get hooked and continue on with the fun.

[jrb]

Thanks Jason!

Beyond this thread it'd be nice if that was better publized -- I know folks that avoid going the TVRC when IMAC is scheduled; this could get them to try.

[wgeffon]

www.mini-iac.com

Everything you'd ever want to know about IMAC is in there.

[jrb]

Do you by chance have L&R throttle mixed with rudder (on/off of course) on the DW Wayne – makes for some wild Yaw Rates!

Do this on all my twins; gives me yaw when they don’t have rudder, and wild rates when they do.

I’ve also found that ESCs/motors operate (start) far more reliably via two channels versus when connected via a Y.

Maybe the DX7 doesn’t allow for this; though my JR642 (circa 99) would.

[WJCJR1]

This option would totally ROCK, I am unsure if I can do that with my current setup. Also not totally positive if the DX7 allows for this. Would definitely be nice to assist the smaller rudder and twin motor design.

Wayne

[jrb]

Do you have a spare channel left?

Here's the programming info for my P-38:

Let me know if I can be of any assistance.

[WJCJR1]

I looked at your diagrams very interesting, I see the throttle mix on Page2. I will have to see if the DX7 has this ability it would be a most helpful item.

Thanks for the time it took to put this together and post.

Wayne

[WJCJR1]

Once more too many photos are just planes on the ground or of assembling planes to never fly as the rain and LOW ceiling preventing any real flying to happen.
