Brushless - the definitive guide

[Slimboyfat]

is there just one tpye of GTB speedo?

with the Novak motors do you have to buy sintered seperatly or do they come as such??

[Kopite]

Isn't there a 'spread spektrum' version of the GTB? sure i saw that advertised in a shop, but not sure exactly what it does (probably something to do with running on 2.4ghz at a guess )

I have to say, i can't imagine ever going back to brushed now, imagine trying to skim motors at regionals!!! There'd be no time to play footy in between rounds

[antnee]

just to tag on to this thread, has anyone tried those brca legal brushless mtroniks motors?

[ashleyb4]

Are they the pink ones if so there is someone at our club who had one and the motors stopped working so he sent it back along came a new one then he had a bearing collapse in it within about a month. But im not sure if that was the brca legal one.

There is Stan, I've not got one though.

See the Novak site for tech info, however I've been running the non 'Spektrum' version with the KO Spektrum for over half the season and have no probs. So it ran fine with 40mhz and fine with 2.4ghz, don't be concerned (in my opinion) that by getting the normal version, you will be at a disadvantage if you change to 2.5ghz at a later date.

I strongly believe that the Novak motors are THE most reliable brushless motors out there. I personally have only ever seen 1 have anything wrong with it, but said person seemed to have a 'talent' for destroying blue motors

It's 2 Novak's now

Is that you Rich? Or the dirty vermin?

Watch out for the "Vermin" !!!!!!!!!!!!!!!!!

Hog(dave) I have a speedo I can sell JUST you cheap, or let you try, to see what will work for you!!!
Let me know eh???

Well it's not Vermin...

Although in my defence I'm pretty sure the magnet coming unglued from the rotor can be chalked up to bad luck, I think my B4 has some anti-brushless curse on it or something

Difference is though unlike the blue motors I'm back up and running with a replacement already

[super__dan]

No it is Rich, between you and Vermin have you done 10 blue motors yet?

I would happily recomend LRP Speedo and either GM/Speed Passion/Orion/Peak motor combo to anyone. The motors are all based on the same tear down.

I have also tried the LRP motors. They are ok, but i think you want to be running sintered really. LRP only do sintered in 3.5/4/4.5 none of which are ideal for Off rd.

I like that style of motor. There is a small reliability issue with sensors - but that is easily fixable by anyone with a small soldering iron and a steady hand. They do need a little more cleaning than LRP motors - but that's because they have vent holes, so they run cooler, it's a trade off. You also have a choice of rotors for tuning the power band. Although i'm not 100% sure how widely available these are. I knw Schumacher stock them, but not sure about anyone else.

Is there anywhere i can find out if an orion/peak motor is compatible with a GTB?

[ashleyb4]

The orion and peak motors are comaptable with all top brushless speedo's acording to orion website.

what is the problem with the sensor that matt was referring to before and what is the fix?

[MattW]

It doesn't effect everyone, and i haven't had it effect all of my motors. Basically, it isn't unusual for the pins for the sensor connector to become detached from the board. Sometimes this happens with heat - i had one motor that would run for a couple of minutes and then stop. Let it cool and it would be fine!! Traced to sensor and it was sorted.

There are a few ways around the problem. You can run a hot soldering iron over it from new - if you are comfortable doing it and have small enough iron. Or you can just run it and see what happens. There's every chance you won't get a problem. If it does go down - you can either repair is as above, or buy a new sensor module.

Note, only attempt to (re) solder to the board if you are very comfortable doing it. I work in this type of trade, so it doesn't bother me, but wouldn't want someone to try it and make it worse.

Orion motors are great with the GTB, very nice to drive.

[Alfonzo]

Can anyone explain why there were so few Brushless systems at the Worlds? (apologies if this covered elsewhere..)

I run BL and love it. Not because it's any faster, but just the ease of maintenance. It's one less thing to worry about. Hurrah
