GAS TO ELECTRIC

[navyflyguy]

Batteries is one of the problems I have been dealing with going to electric from gas. My first post I was looking for help with motors, and Dewey H Lee wrote right here so I took he was talking about himself, but he was talking about Hobby Squawk members. So I will copy my post here.
My son gave me three systems! Why ?
