Some of the best advice I ever read! Thanks for taking the time to type it all up for the benefit of new fliers who are starving for information! I have the T-Rex 600 electric and it is one fine machine. Thank god I've never done anything more than a new set of blades when the wind tipped it over on the ground while I was looking at my timer (not done flying until the blades have stopped, like you said!) Very good stuff.
