Whats a cold fusion? Sorry.
But anyway are you using the stock radio on your hyper? Because my receiver broke recently it kept making the throttle jitter when the engine wasn't moving so i replaced it with a Hitec receiver and now it works fine.
First cold fusion is a new nitro fuel supposedly it keeps temps down dramatically even at lean conditions. And provides great lubrication that doesnt give you a brown stain on your body.
Second on my hyper 7 Im going spektrum dx3s and im gonna buy 3 spare receivers. 1 for my revo, 1 for my losi 8 and one for my xray.
with hitec 7955 titanium gear servos. with an 11.1v lipo pack.
