Is there any conceivable way of putting 2 batteries inside the Tamyia KT? I've tried several things but so far, have not succeeded. Although I can physically install the batteries, the second one interferes with the turret rotation motor.

Has anyone managed to install the speaker more towards the rear? I think this might solve the problem. If so, how is the hull held down?

I want to give my KT the same running power as my Tiger.
