Yea for sure guys I will for sure take some lessons on a trainer at my local rc airfield, remember I want to make sure everything is working like all the electronics and make sure the engine turns on... so I did a little diggin in side my plane and found a futaba 600 mah nickel cadmium battery and I found a charger with all the goodies the guy gave me. So now I don't think the 9 volt matters I'm pretty sure it's for a led on the front of the cub. Does anyone know how to store the battery properly because I know lipos you have to have a some charge in it?
