I am a old school nitro dude. We used to use foam and animal gauze, or velcro, to mount our electronics. Nitro has a propensity to shake a bit
For my N5c it just did not seem right. Chris Sexton suggested Parma PSE Pro Servo Tape 1"x36" Roll . Unreal - I love it!!!!! After a few days it firmed up, but has a flexible feel to it.
I redid my other heli, and have to order more for my next N5c build -- come on Father's Day Sales!!!!
Thanks Chris!
