Small motor / Big performance

[motorman1600]

Here is what I am looking for. A small motor 280 size can( losi Mini) that has the same or nearly the same performance as a 55 t 540 motor.
I am using the axial trans in a 1.9 class and I need the small motor size because of space issues and weight. I am trying to stick with brushed before I have to turn to the brushless motors.
Any leads would help. Thanks

This motor is a little bit bigger than a 280 but fits in the losi mini and can be converted to fit the axial tranny too. It probably has more torque than a a standard 35t motor as well.

The 454 is probably your best bet. It is still a bit longer than a 280 motor. Your other option is a brushless motor.


Are you limited more on length or diameter?

Are those legal for 1.9 class?

For some reason I thought there was a motor size limit but maybe it's just voltage...

Just voltage limit in 1.9 class.

I am limited on the length more than diameter. But I have moved the trans off set so I can get the battery in on the side next to the trans. Length wise, a full size 540 hits my link mounts.
How about the 3745 promax motor??

How about the 3745 promax motor??

if you dont like power/torque ...:lol:

 

[JohnRobHolmes]

The 3745 is teeny, and doesn't start up well.

JRH, can a 454 work in a 2.2 with 12/96 gearing? Is it lighter than a standard 540?

I have two of the 3745's in a Cliff Climber. I am currently trying to return them for a refund.
Both motors are now stalling periodically without startup. You have to spin start them to get them going again.
The sellers fix is to pull/clean/reseat the brushes. Works for 1/2 - 1 pack and starts stalling again.

I learned my lesson with these Promax's.

I haven't tried the 454 in a 2.2 yet. The biggest issue is the length of the shaft, it is pretty short and the pinion may not reach the spur.

I have run the 454 in a 2.2. My opinion is there is no advantage in using them in a 2.2 unless you need less wheel speed and torque.
I have a bunch of them and they are awesome motors in the right rig.


sweli,
on your 3745 I had one with similar problems. I bent the brush springs to increase the tension and cured the problem.

I enjoy the 3745 motor because it is not perfect and challenges my brain.
