Just completed a build of a new 450 Pro V2 3GX (v2.1) Super Combo. Heli seems to fly great. Tail holds nice in a punch out, elevator tic toc (have not tried aileron tic toc), front and back flips. The problem comes when I do a simple aileron roll (right.. have not tried left). The tail blows out and turns 180 degrees so in the end the heli is facing me when it started nose away.
My first step to sort the issue was a complete reprogramming of the the 3GX 2.1. Still happened. Next I did the tail grip flip mod but this did not fix the issue either. Tail linkage is silky smooth. I also checked tail grip bearings. Also confirmed orientation for 3GX in settings. I don't know what else to do. The 3GX 2.1 on my 500 works flawlessly. So far it only seems to happen on aileron roll. I will try left later today to see if it does it in that direction as well but for now this is all the info I have.
The only other 450 to compare to is mine but the setup is significatnly different so no help there really.
