RE: Polk Hobbies C-47
Here you go. My Polk DC3 done as an AC47.
Gatling guns (self built)on it actually spin, each has it's own 250 brushed motor with home built gearbox to spin em up.
Servo actuated switch turns em on, and is actuated from the TX. Pretty neat on flybys, gearbox noise sounds like the guns are buzzing as they spin.
