Hi. Here is my KV-2 built from Trumpeter's kit with added custom made mechanical and electronics parts and a set of metal tracks.
The custom designed electronics control acceleration/braking/steering, mimiking the heavy feel of the KV tank. Smoke effect is linked with acceleration. More photos of the build will follow later on. Thanks for looking. Comments and ideas are most welcome.
All road wheels, return rollers, and idelers each contain two ball-bearings to ensure smooth running and acceleration, especially at very low speed. Idelers have working track tensioning.
