Mike, you have the same transitter as tomflier. Help me out. My CHP has the exact same innards, except that the the ratched spring is flat rather than with a nub on the end like yours, right? We weren't sure if we should bend the spring or replace it with a flat spring. I wonder if that heli version spring is something you can order.
On the switch to change HH usage on the same model, "not me". I am fairly confident that I would choose the wrong switch setting and piroutte my heli into oblivion. So I have two models. Piccolo and PiccNoHH. This way I know before I power up my bird that I have the proper settings. Manual page 77? You mean these things come with a manual? That's what I have YOU for! :-)

tomflier, I guess I need to do more research on the CP setup used by the picc pro. Eventually I want to get there, and as always, I want to do a year of research before I make a decision.
