Don't go too heavily on the power output guides...

It all depends on how you measure it..

A better idea is probably gleaned from other drivers' experiences on track.
If your competition is running the 9-10's.. then the 5.5 would be just about right. Not sure whether I'd go down...

My experience (subjective of course!)
5.5 = 10-11t brushed
4.5 = 8-9t brushed
3.5 = 7t brushed

Motor-wise and gearing wise - having a spaking motor might even ruin your lap times. All the power in the world is useless if you can't put it down. A car that can't put down the power is hard to drive, inconsistent and toasts tires..

Most ppl actually go faster with a slower motor - they become much smoother in an effort to eke out the very last bit of power from their motor. Their lines improve...

chuck in a faster motor and they're all over the place!

i am wanting to purchese a 3.5 and would like to know if the 4.5,5.5,6.5,7.5 arms would change out in the cans if I wanted to save money and not have to get whole motors?

Unlike a nomal brushed motor which the arm has all the wires wind around to give it the how many turns the motor is. In a Brushless motor the windings are in the can and the arm is magnet.

Yes you can switch the arm between the can but you'll have go get the can 1st in order to change the speed. ( In a brushed motor we change to a different turn arm )

Hope this helps.

LoL... nice to see ya Marcos!

Haven't had the time to run the car lately. Bit of a shame!
Did manage to bin the car at the end of the straight on the track we visited a few weeks ago. Bent the top rear bulkhead!
My mistake - got a little wide trying a different line and landed the car on the marbles. Slide straight into the end barrier!
Ouch

Moontrap - this gives you an idea. A 3.5R track for sure!


Track runs clockwise for those who are interested.

That's a big picture...Nice track!

What are the bearing sizes for the 13.5 brushless?

Yikes!, thats a huge track.. we dont have many tracks like that here, a few nitro tracks that are that big.

I'll probably go for the 5.5 , as the 3.5 is way too much motor for the small/medium tracks i run on.

Thumbs up

Geez, could that photo be any bigger? How about a straight upload w/thumbnail to the thread so we don't get 3" wide browser windows?




Ok, I got my new GTB with 4.5 last night, and installed it into the EDM dirt oval car. It's really a nice setup and super easy to install. Very nice quality, too.

One question, is there a reason that all of the various sensor wires are different lengths? I'm kind of a wiring freak, and they are too long and besides uneven, they look bad when everything is installed. Why no plug on those to the motor?

Also (ok, two questions), does anyone make any brushless motor storage cases yet? Maybe something that has provisions for the sensor wire/plug...





Cool so far. Pics of the car and install later today.
