Motor compare
 

Hello everyone,
I have a question, which of the two motors is the batter?
1.muchmore specter 13.5T
2.hobbywing G3R 13.5T
Which has higher speed?
And linear feel of control
THX!

Maybe a mod can move this into Radio and Electronics....

Speed you mean RPM? at equivalent timing? It depends on the rotor.

Get a Trinity Motor!

FYI Muchmore Specter motors are not ROAR legal so if you ever go to a big race you cannot use it. Both are good motors, but I would get the G3R just because of this. The normal non-specter Muchmore sucks. Also, Trinity Certified Plus Motors are not ROAR legal as well since motor price cannot exceed $149.99. They say it's legal, but it isn't.

Trinity certified motors regularly pass Tech at large ROAR sanctioned events. That price rule isn't enforced, it may as well not exist. Trinity are also not the only brand that have motors that exceed that price cap.

There is so much more to a motors performance than rpm. After recent experience I will not dismiss the Hobbywing G3. It just has to be timed and geared correctly. My experience is with the 17.5 version. I can also add I have Dyno tested the 17.5 and can compare it to other Dyno tests of other motors (all my data). The 17.5 performs best at around 35 degrees of timing and slightly below. Going above that mark is doing nothing more than generating excess heat as its amp draw jumps significantly. I am a fairly good driver and test motors for one manufacturer both Dyno and track. I can say that I have never tested a Muchmore.

I always tune the motor to the track. Larger track use a smaller rotor with more rpm, smaller high grip track use a larger (but legal) rotor with high torque. Most of the time people aren't being slow because of their motor. It's usually their driving, setup, gearing or motor tune. If you want one of the best motors look at R1, Motiv, Fantom, or Trinity.

The "higher speed" portion of your question really needs more context in order for it to be answered. What is your application?
A more linear feel can be achieved with almost any motor by tuning the ESC. and with higher wind stock motors this is much less of an issue than mod motors.

what means "motor performance"?
isn't it speed? or temperature?

my higher speed means straight line speed,because when I out of corner to straight line,my final speed is slower than my friend,his motor is muchmore specter 13.5T,my motor is surpass v4s 13.5T

There are lots of parameters, the most important one you missed is torque. Top speed of the car is largely a product of the RPM and torque of the motor, the timing and gearing you've set, as well as other things like aerodynamic drag, drivetrain drag, momentum carried onto the straight etc.

His motor is an outlaw motor, yours is an approved stock motor. I'd expect his to be faster, but it's also not race legal in most places.

so!!!If I buy hobbywing g3r，this is approved stock motor
Performance slower than specter 13.5t,too?

I'd expect the Hobbywing to perform similarly to your Surpass.

I have G3R and some outlaw motor, you simply cant gear G3R heavy enough to have similar straight line speed yet the motor will get very hot. if all you want is similar speed, get the motor he use. and maybe prepare another car for attending those big events.
