Fold your blades the same way and make sure you have the same amount of pitch positive as you do negative. You may have to do the link mod. I think you extend the links 3 turns, but it may be shorten them. Lee will be able to tell you. I did it but my mind is not working tonight lol.
Also, if that works for you not locking that plug in place, great. However with the vibration of the heli, it could come off in flight and cause a crash. And if you are over your house, this is a real pain in the ass lmao. My suggestion would be learn where that T-Hold switch is and always be ready. In time you will hit that switch without even thinking when you know you are going to crash.
Myself, I don't hit throttle hold. I have trained my fingers to simultaneously flip out of idle up and lower the throttle all the way. I really need to learn the throttle hold, and now with a nitro, I need to train myself to hit the kill switch when I know I'm going to crash. That way no dirt gets sucked into the engine.
