Hi guys I need some help here...
I bought a EPO Parkjet (kit) from HK http://www.hobbyking.com/hobbyking/s...dProduct=18249
I added some photos that will show the way I put all the gear in there.
I use 2 HXT900's, 30A ESC from hobbyking, an e-flite Park-250 motor and a 1000mAh 2s Lipo nanotech.
The problem I have is that whenever I launch it it dives straight into the ground with a left roll. I also tried it without motor just to see if that was torque roll but it still did the same.
First I changed the CG (from 2mm from holes to 2/3 of the holes) by putting the lipo further back but no changes. After that I pointed the motor more up (from 2° to 3-4° I think) but no changes. Next I tried trimming it to the right but no changes either. the faster I throw the more the effect, slower and without power it was less but still unflyable. I don't get the chance to get my hands on the controls.
I tried different launching methods (using finger holes and throwing straight and swinging it away by holding the wingtip) but using the finger holes was the best.
I don't really know what other things might be the cause so that's what 'd like to hear from you guys...
I've made a cut in the left wing leading edge to put the rx antenna in but I don't think that would have that much influence on the flying...
I hope you guys can help me
Btw thanks Flitetest for all your reviews, it got me in the hobby in no time and I love it lol
