The EFlite P-19 comes very well packed it a fairly small box but dont worry, its all there!
Whats in the Box:
(1) PT-19
Whats not in the Box:
(1) EFlite 450 outrunner (I chose to use the EFlite 480 (1020kv))
(1) EFlite 30 amp ESC (40 amp if you go with the 480 outrunner)
(4) EFlite S75 servos
(1) 4 or 6 channel RX (6ch if you want differential aelirons)
(1) TX
(1) 20c 3s 2100 lipo
(1) Set of Deans or EC3 connectors
(2) long servo extensions
(1) Y harness (if you chose not to use differential on aelirons)
(1) prop (12x6 for the 450, 11x5.5 for the 480)
(2) 1/9 scale pilots
The Build:
Wing:
The first step is install the aeliron servos. You will need to add servo extensions to both servos. I highly recommend that you use tape (I used hinge tape (see photo)) to secure the extension to the servo lead. Attach the string to the extension wires and then SLOWLY pull the wire through the wing to the opening on the TOP of the wing. This may take a little wiggling but take your time. Repeat for the other wing half. I DID NOT attach the servo to the wing covers at this time. I center servos and such near the end. Its really the builders choice as long as you dont mount the servos.
Next is to attach the wing halves together. I used 6 minute epoxy and painters tape. I love the purple painters tape because it is very low tack and wont damage the plane and wont leave residue behind after being removed. You can get it at Lowes, Target or Walley World.

Let the wing halves dry for an hour...but no worries we can keep building.
Rudder and elevator:
This is very easy, simply slide them together and use the include lock nuts to secure them. Check to insure the elevator has free movement up and down with no binding.
Now mount the tail to the fuse. Make sure you use the washers to help spread out the stress on the wood. I had a very noticable gap between the top of the fuse and the tail (see pict). I spent some time with a file trying to make clearance to move the tail forward to fill in the gap...it wasnt worth the effort. They include a couple of pieces of blue monocoat and it would be easier to just use one to cover the gap.

Fuse:
Install the elevator and rudder push rods. Install the servos for them from the TOP of the fuse. For the elevator you will need to install the servo block first...please be sure to use loctite. Also install the velcro for the battery and the safety strap.

Next install the motor and ESC. The 480 gets installed all the way to the top of the motor mount and the 450 about 1/2 way down. Use loctite on the screws for the "X" mount and for the screws to the firewall. Having a motor come loose during a flight is not fun! I installed my ESC using velcro and ran the wires out through the side behind the motor.

Electronics hook up:
By now the wing is dry. I hook up all my electronics and bind my RX to the TX. Once the bind is complete the servos are now centered, remove the servo arms and place them at 90* from the servo. I used the "easy connects" that were in the hardware to connect all the pushrods to the servo arms. They make adjust the control surfaces flush very easy and quick. The rudder and elevator are the easiest. My rudder was slightly warped at the top. A heat gun and a few minutes can fix it. I havent as I want to maiden her as she came for an accurate review.

The aileron servos are next. I used regular CA and a kicker to mount them to the covers after I had placed the servo arms at 90*. Please be sure to center the servo arm in the opening. You do not want any rubbing. Now you can use the included screws to mount the covers. I place the push rod into the easy connect before I mount the servo and cover to the wing.Just makes it easier then flexing the control surface to get the wire into the hole.
USE LOCTITE ON THE SCREWS THAT PRESS AGAINST THE PUSH RODS OR THEY WILL COME LOOSE AND LOCK A CONTROL SURFACE IN PLACE!!
Wing Attachment
Make sure to use the washers with the wing screws and only tighten them till you see the covering begin to twist or compress. Over tightening will break the wood. Now flip her upside down and install the landing gear.
Cowl Installation:
This is the part that I would freak at...drilling holes into the colwing and plane...but now worries as its actuallye easy. I line up the cowling insuring that the black on the cowling lines up with the black on the fuse and the top edge is aligned with the back edge of the balse support that locks the canopy in place. Use some painter tape to hold it in place...check the other side to insure its lined up there as well. Now look at the motor shaft and insure its centered. Tweak as needed and then secure with more tape. Now drill 4 holes about 2mm's back from the cowling edge using a drill bit thats smaller in diameter then the screws. Now install the screws.
Now add your prop and you done!

Preflight:
Verify that all control surfaces move inthe correct direction and that all surfaces are flush. I set my aelirons up for flapirons so I had a little tweaking to do. Double check your CG and go over the plane one last time.
Build Time:
Build time is 4 -5 hours depending on your experience.
REPORT CARD:
Good:
- Covering had no wrickles
- Easy to follow instructions
- Great looking plane
- Larger battery area
- Adjustable firewall blind screws (makes using various motors easy)
Bad:
- Warped rudder
- Poor fit of tail to fuse
- Pilots not included
FLIGHT REPORT:
Weather:
- 7-12 mph winds
- Sunny
My Set Up:
Eflite 480 (1020kv) with APC 11x5.5E prop
EVO 25 3s 2170 lipo
4 S75 servos
AR6100 RX
Dualsky 40amp ESC

Maiden:
I have been looking forward to this flight for a week. Calm winds are not forecasted for at least a week and the rain finally stopped so out I went with the wife in toe with the camera and managed to sneak in a single flight.
ROG was easy and she tracked well for a tail dragger in 2 inch tall grass. She was off the deck in about 50 feet as I was easy on the throttle and wanted to keep the tail pinned to the gorund to prevent nose overs in the tail grass. I got her to alititude and left the sticks go at 1/2 throttle, she dropped her nose and the left wing tip...now worries as a few clicks of up trim and 4 right had her flying level. I took her to WOT and she started to climb a little and I noticed that she dropped her nose in turns so I need to move my CG back a little (I was slightly nose heavy to begin with playing it safe on the maiden).
Rolls on low rates are not going to happen...high rates and she rolled but they were slow. I need to move my control rods up a hole on control surface as my DX6I is already maxed out and I had added differential (30%) which is too much so I dropped it to 15% for the next flight. Loops were nice but I need to remove the EXPO (30%) as I felt disconnected and the response was a little slower then I like.
Landings were easy, pull back the throttle to 1/2 stick, turn in, and chop the throttle to 1/8 and she settles in and lands with ease. I was even able to taxi her back to the truck as long as I held full up elevator to keep the tail pinned.
Report Card:
ROG: Easy and relaxing
Glide: Level with a gentle downward decent
Rolls: Slow, on high rates rolls are 360* in 2 seconds
Loops: Easy, watch for fall out at the top if you have too much elevator
Speed: Scale speed, 25-40mph max on my setup
Landing: Easy, lands like a trainer
Beginner: No, would make a nice first balsa plane or first low wing aeliron
Summary:
Beautiful aircraft, she simply looks amazing in the air and the color scheme maintains orientation with ease. She flys well, almost trainer like but with better looks. Take your time and fine tune her and she will quickly become one of your favorite flyers.

UPDATE:
I made a few changes for the second flight... moved the CG back 3mm from the most forward recommended CG setting and switched to a APC 11x7E prop. The improvements are impressive...top speed was nice, good thrust, improved performance in loops and the roll rate increased. It stopped climbing with increased power, no nose drop in turns. She flys better then the PZ P-51...and now has moved to my "favorite plane status"!!
