Jared set me a challenge this weekend, as he had decided he wanted to make a remote control tank as part of a World War Two project for school. Not one to be beaten I set to dismantling the collection of broken radio control helicopters I collected at the Brighton Centre. I soon found that the motor and pinion meshed perfectly with a 46t 80 pitch gear, so with my trusty soldering iron, some 16g piano wire, Jared's tank was soon underway. Once constructed all we needed to do was create a 'tank' from an old box and the job was nearly complete ! ( you know bodywork has never been my strength ! )
You can see we even used pin tube to mount the shell to the chassis !
Under the covers you can see the size of the motor and the backend. For the technically minded this is a 7 to 46 gear ratio! Initially built with a set of 1/24th JKB rears (on large polymers of course !), however, these seemed to provide to much resistance and cut the motor out, a little experimentation found it ran best with a gear on each side.
As you can see in the attached video, it's got a good turn of speed ! Wonder if I could get a saloon body on it - great fun !!!
See the tank in action

Can anyone see the video, doesn't appear to work to me !!
What video? No sign of it!
Hope this is not going to be a proposal for yet another new class!
I think the video will work now....
It works but don't blink or you will miss it!
I would start using those motors in your cars - you might get better results........!
Very good, but what happened to the radio control steering part of the project?
That will have to be on the Mk2 version - couldn't do it with the RC elements from the helicoptor as the tail rotor is always powered !
