Ok just a few more q's

Will 4 of those 1/3aaa rechargable batteries hooked together work fine with rc and my hitec feather rx?if not what battery pack do i need

What prop do i need for the classic cessna - p51?

how can i make a throttle for the .010

what would the guillows 400 series be like with a cox .049?

If this fails i am going to build a sleek pattern plane like a formosa but smaller
