are all 17.5t brushless motors equal?

[tonydevon]

might sound a silly question but Im just wondering if for they are all basically the same but with different branding and pricing, surely if they same winds/kv rating and getting same voltage then they shouldnt differ, or do they?

I currently race with 17.5t in blinky

using a turnigy trackstar motor, it seems to work fine and I have no problems with it, but do notice that others are that in my opinion noticably quicker, obviously I know driving comes into it a huge amount, but it made me wonder if a fancy branded expensive motor would in fact be quicker? but that defeats the point of the 17.5t limit?

sorry for my rambling but as a newbie to brushless Im still learning

No. Not all 17.5t motors are equal. You may be better off searching on rctech forum because they are mainly American on there and the yanks love their 17.5t stock class. Hope that helps

In US, they are huge on this type of racing.

They talk about weight of the car, transmission mods(slipper eliminators, cut gears, ceramic bearings and more), short stack motors, temp of the motor after the run, how much timing they have on the motor, the IR(internal resistance) of the cells they use.

There are also some specialist companies that only deal in this type of motor.

But as per previous post look on rctech for maybe some advice.

But they pour lots and lots of money into the cars to get that extra edge.

There 2wd buggies can be something eye watering in costs.

The theory behind a motor design is the same but some are lighter and have more air flow, all things that help to keep a motor consistent and cool through a run.
Each motor including yours will have a maximum/optimum operating range which could be different from track to track.
Eg I like the Gforce 17.5 motor for small/med indoor blinky TC with 4-4.5 FDR and 40* timing (any less FDR or higher timing just makes heat not performance.) Other makes can go lower FDR and higher timing without compromise, Trinity for example are designing their motors for this application but are premium cost.

17.5 t is large in uk my club really only runs this class and the brca Clubmans is run because there was no 17.5 at two day brca nationals

There is very big differences in the motors and nearly every company make a stock class motor made slightly different for the mod turn motors

Best ones I have seen are
24k trinity
Maxllia from trinity
Speed passion v4
G-forces new red can motor
Budget team wave

And there will always be difference in motors they try to push each new model to be little bit faster. it will always be like this unless u run a hand out esc and motor but then some one will have better batteries servo handset more tyres and this go for any scale any class u run

Ur motor is a cheap version of a reedy sonic one but with normal bearing not the expensive free running ones that are in the reedy so ur motor unless it one of the better ones won't hit the same Kev and rpm as the sonic does

ok thanks guys, maybe then its time to hit the web and do some shopping for a better quality motor.

the turnigy stuff works fine and has done its job of getting me started on a budget, but now I need more
