Thanks wedgewing !
Maybe you could play with the holes on your servo arms and/or surfaces control arms to remove some twitchiness? It would make the plane less manoeuvrable in extreme attitudes though. But I believe it is more a sport plane than a 3d ?
I used e-flite six series motor and 40 amp esc in my stryker brushless conversion and I'm very please with it ! So much performance, but expensive set up. That's why I asked about your experience with the e-flite products, as I have been very pleased with the rimfire in my extra. I plan to put the smaller rimfires in my Sig Dornier kit. I will check thourhouly for the shaft and prop collar to be secure before I fly it
