PT-19 Build Day #4

I got a little further than I thought I would tonight and am now held up by 4 missing screws...


Motor and ESC were easy to install, especially now that I am familiar with the "backwards" motor concept. 890kv 450 size motor, and a 40A ESC with 3A BEC. Bound the receiver and checked the ailerons, elevator, rudder and motor. Had to reverse the rudder servo, but the others were fine. Re-centered one of the ailerons and the elevator. Easy, peasey. Realize now I didn't program the ESC. I'll do that tomorrow.


Had to break out the sealing iron for the first time. I guessed that each number on my hangar 9 sealing iron represented 100 degrees F, set it at 250 degrees (220 deg + 10% for the sock). Worked wonderfully after smoke stopped coming out of it... I applied the center blue strip (there were two blue Ultracote strips in the kit, no instructions. I suspected they intended for me to cover the middle joint between the wings on both sides. Fit perfectly suggesting this was in fact their intention.



Here's why I had to learn how to iron Ultracote. The wing walk strip (that black band along the fuse where the pilots can step) peeled back on the port wing. It went back into place easily and looks great. 



The center strip and the repaired walk strip.



I loose fit the cowl in place. E-flite did not include the 4 screws that I need to secure the cowl to the fuse. I have 4 similar screws, but two are the same size, and the other two are shorter, and one of those is shorter than the other. Since I have time here, I am going to ask Horizon to send me the screws. She is beautiful!


So, I may tape the cowl on and hang her up until they send me the screws. This is one spectacular model... wow!
