so whats the difference between hobby electric motors and the motors in tycos
by performerrpm on 2010-03-09 02:16:19 UTC
just wondering cause i was at a hobby shop and seen a losi rx280 motor i thought would replace the mabuchi motor that was in one of my bandits and when i hooked it up directly to the battery to comapre it to the stock one it seemed like it was gonna go twice as fast, once installed tho it acted like it was getting no power wouldnt even hardly back up. is there something in the electronics that is different?

im pretty sure bandits have a 370 motor in it

the motor matched up perfect in size to the 270 that i bought i was actually lookin for a 370 since i was told it would fit but all they had in stock was brushless. i will say that if i held each motor in my hand and hooked them direct to the battery the stock motor didnt have neer the torqe and nowhere near the rpms either and when i put it in one of the extra transmissions i had for testing it for fit it looked like it was gonna sling the tires off the wheels, once i hooked to the wires from the circuit board tho it didnt have near as much jump. like i said it bareley would back up and wouldnt back at all in hi gear so i dont know whats up with it. looks like i may need a new stock motor

ye due to weight the 280 dont have as much power behind it theres some good 370s on ebay

you think they will work ith the tyco board and battery

i tried a orion 370 raider motor in a bandit and it lasted about 2 minutes before it fried the electronics...it made less torque but a little more top end. I dont recommend it!

thats what im worried about, just the short time the rx 280 was in the banndit i could smell the glue on the board from where it was getting hot so i pulled the motor back out. think for now ill just get another stock motor for it if i can find one without having to buy awhole nother parts car.

the built in speed controller cant power them then

ill take a look after at my spares i think ive got a 370 that i can send u if u want it
by performerrpm on 2010-03-10 10:20:30 UTC
yeah id be interested in the 370, but would i need a speed controller for it?
by djdarkforces on 2010-03-10 13:26:58 UTC
i only got a tyco stock motor here
by performerrpm on 2010-03-10 18:40:47 UTC
tyco motor? what size is it or is it the 370 you were talking about. at this point a good stock motor would be fine
by djdarkforces on 2010-03-11 08:41:40 UTC
ye its a tyco stock 370

This!
He's right, the stock Tyco transisters for the speed control are just strong enough for the stock motor. As soon as you hook up a mod motor, it cant handle the larger current draw and over heats the transister and burns them out.
This is why it seem's to loose tourq but gain RPM's (with the stock speed control). Once you get a speed controller that can handle the current, the mod motor will have all of the tourq back plus the added RPM's.
If you really want to do it right, get your hands one some 1/18th scale electronics. You'll need a speed control, receiver, transmitter and servo. You'll have to replace the tyco servo with a real one. But the work is worth it, you'll get real digital proportional steering and speed.
Just be carefull to not turn the gear's into soup.

thanks ill take the 370 if your not using it and thanks both of you for clearing that up on the speed control, if i can make a stock type motor work with this paticular bandit i wanna go that route just because its condition, i do have a bandit im gonna put the trans from a twin hopper thats electronics dont fit under the cover so id have to mount on the top of the cover, i might think about all the hobby stuff if i can find a dual motor speed controller,

sorry aint been on my net has been down for 5 days if u still want it let me kno
by performerrpm on 2010-03-17 13:41:00 UTC
yeah ill take it. by the way does it still have the gear on it?
by djdarkforces on 2010-03-18 06:38:26 UTC
ye its got a 8t on it message me ur adress ill send it out

Yes. It shouldn't be too hard to replace the MOSFET's used in the stock electronics with modern higher current pieces. Electronics aside, the real limitation is the gearbox. Tycos stripped gears left and right with the stock motor. Imagine what an aftermarket motor will do to the gear box.
