Motor replacement help
Posted 29 July 2014 - 09:01 PM
I would like to know all of your opinions on these motors and if they arent too great, im open to suggestion (given they arent very expensive, around the price range of these) .

Yes, it does rev up almost instantly. I just don't want to wait until my 40 dollar, foam spewing toy goes down in flames. I know the whole thing won't catch fire but I'd rather not burn out anything related to the pusher motor because I don't think I'm ready to rewire that complex junk.
Burning smell is normal. Don't fire continuously, and don't keep the motors revved for too long. The rev time is probably low since you over-volted it so you can afford to keep it off. Don't worry about it until something catches fire.

These are the motors I use and they work astoundingly well on 2s and 3s Li-Pol and would recommend them highly; http://www.heliguy.c...earing-motor-B/

That being said I would pay little attention to the operational speed those motors are rated at, it is no secret that without very high inertia in the flywheels torque is the main factor in a good blaster motor, furthermore operational speed can always be increased on any motor (to a point) by simply adding additional voltage and being able to supply the current demands. I haven't seen this article on Britnerf - but better brushes would no doubt help the reliability, though I would still retain 9.6v is far too high for such a wound motor;
At 5v they draw in nearly 5 amps as it is, with two motors at 5v you will be needing a constant drain of 10amps from your Ni-cad pack - which is certainly obtainable but a 9v I'm not so sure, you could also expect a lot of noise, heat, etc at these high voltages.
All in all, my humble suggestion would be buy buy RM2's swap the brushes if you wish and buy a 4.8v Ni-cad pack and rewire the whole blaster with high capacity wires. I'm sure you won't be at all disappointed with the results.
Other people swear by Tamiya motors - maybe someone will chime in here about them? Personally I don't have any experience with them to give any advice.

EDIT: I have found some tamiya mach dash motors for cheap and would like to know if i can run them at 6 volts with one of those slot in nicd packs.
