I think I know where your coming from. It was a bit painfull shelling out the money to get an AstroFlight charger that could handle the high current 4S and 5S cells.

Don Glider Guy: I have no problem rotating on take off. Of course the power set up I have has outstanding excelleration. In any case, this is not a plane you want to jump into the air, give it plenty of speed prior to pulling up. You might want to have a bit of down elevator trimmed in from the start, if it's like mine it will want to climb. Good luck with your maiden flight.
