Hi Mark,

Thanks for your response. I am pretty sure that I have the prop on correctly. I thought it would only go on one way. During my two successful flights (so far) the prop pops off when I kill the throttle, but thats another problem.

My neighbor and I tried three attempts to launch it again this evening with no luck. I think I damaged my receiver from the impacts. I am using a Sirus Pro series charger to charge the 1700 ma batteries. Perhaps they are not getting a full enough charge?
