    Small plastic gearbox 90 degree (right angle drive)

    Post  david f on Mon Feb 18, 2013 10:11 am

    Anyone know where I can get these? The idea is to transfer a small (300 series) motor drive through 90 degrees. A small reduction (3:1 say ) would be handy but not essential

    The gearbox needs to be quite small (20mm cube, light, rustproof and cheap. (I need about 4) I know I don't want much!

    Nothing on ebay. Nothing on MFA. Any other suppliers you can suggest?

    Have you checked RC-Sub shop on eBay, David? Or failing that, how about Tamiya...dont they do them for their tanks? Another one just popped into my mind...Howes Models in Oxford? www.howesmodels.co.uk

    Thanks Richard!

    That looks very promising - I will get one and have a go with it.

    My Tamiya gearbox has just arrived and looks very promising. Thanks for the tip.

    A nice bit of kit but it needs assembling and why is everything smaller than the way you imagined it!

    Now assembled.
    A nice little motor and gearbox combination that fair whizzed around when I applied 12v to it. (No voltage mentioned in the instructions.) Smoke appeared 30 seconds later! Now dead.

    Oh dear what do they run these Tamiya vehicles on a couple of pencells?!

    Oh dear, David...not the escape of the magic smoke? Maybe a start at low voltage would have been a better idea.

    Can you swap the motors over?

    That motor is rated for 3 volts, 12 volts is overpowering it a bit!

    Have you considered gearsets from slot cars? They usually use crown wheel sets, giving the 90 degree angle, and tend to be geared down about 2 or 3:1.

    You can get slot cars in many scales from 1/24th down to 1/72nd, so you should be able to find gears small enough.

    Don't know if you sorted this but I use rc helis. 450 size or smaller use belt drive tails that have 90 degree gearbox. Might work?

    Thanks for the suggestions, chaps. (EMA is a new one to me and looks very interesting.)

    In the end I bought 4 of the Tamiya gearboxes for the Nordenfelt project. They look fine (with or without the 3v motors!) They have not been fitted yet while I get on with the fibre glassing. Gorgeous weather for everything!
