I have a T34 Taigen that is less than a year old. Built professionally buy some one else with upgrades. I spent a lot and it never worked as I asked. I just wanted it to move like a real tank [crawl] and shoot.
It never did either. It runs around like a scared rabbit. I asked for help and got 10 or 12 pages of how to reprogram the controller. I just wanted to chase the cat around not become an electrical engineer. I am a mechanical engineer and we have a natural detainee for electrical and control engineers, I am sure the feeling is mutual.
I would definitely sell it if I could verify anyone out there is for real.
