Whew, where to begin. Icould use some guidance for selecting motor, prop &batteries for park fliers. I flew nitro planes about 15 years ago and got into electrics about 6 years ago with my step brother but have been out of the hobby for probably 5 years now. Ihave pretty well forgotten everything to do with power system &prop slection. My wife has taken an interest in learning how to fly and now I'm trying to remember the stuff my step brother taught me for electircs.

Ihave an Alfa Models P-51 that Iwas flying with NiCad batteries but Id like to switch to LiPoly. The plane is currently equipped with a Graupner speed 300 motor w/gearbox turning an APC 9x6 prop. I have some ElectiFly LiPo's, 1500 mAH w/8C max discharge but I am not sure if they will work for this plane or not and if not what kind of plane they would be good for. I realize I will need a new ESC since the old doesn't protect the LiPo from discharging too much.

It flew great before. Enough power to do some loops & rolls but was not a rocket, just a nice smooth flight.

Thanks in advance to those who can help shed some light on this subject.
