I've switched a fair few helis over between 35Mhz and Spektrum on my PCM9X2 with Spektrum module and just plugged and played.
Finally found an Rx that would fit in my Mini Blade so I've just been sorting that out. When I come to power up and bind the 1st Rx is FUBAR
Get it replaced at the shop and this one binds fine but one wing servo and one tail servo the centres have shifted by 40 and 24 points of sub trim respectively. Why's that then? Anyone else seen this or is it common and I've been lucky with various helis?
