I was thinking of a BARC controller since I have been playing with them but it requires an rx18 as well, don't have that kind of space. So I will look into other controlers.

I decided to move the fuel tanks to the rear for the TD but haven't done it yet. I can then fudge the size a bit as necessary. Also, I got a NIMH battery and was going to gut the AA box and it will fit right into that.

The 75 mount has a box that the ammo rack is in, then the gun sits on top of that box. I can make the box out of paticard and use it to hide something in.

Still working out plans guys so stay tuned.
