I chop my throttle when it goes in too.
Unfortunatly that's not the only cause of 4-in-1 failure. Several people have had issues where the 4-in1 just seems to quit working properly. My 4-in-1 worked great one day - no wrecks - and the next day it only provides enough power to lift the CX about a foot high and that only lasts for a couple minutes. I've rebuilt the heli, replaceing with new, both shafts, all blades, and gears, flybar and verified that the bearings are smooth and that both my batteries are good. It still won't lift properly. I don't know what happened but I've read of several people having the exact same experences and results.
I've also read of people having good luck with the Vortex 4-in1 and the last time I saw one it was $35 which is a pretty good savings over the e-flite one ($50) and if it does not have the tail drift issue it might be worth the gamble to try one.
But that's not really why I started this thread. I was really just courious which parts were interchangable between which helis.
