Which brushless ?

[Gayo]

Hi, as many of you, I'm looking to take the brushless route. It will be for a X-5 and later a B4.

It's for racing only so I'm looking for very good power control, I guess it will be a sensored one. Probably 5.5 and 6.5 for 4WD, 6.5 and 7.5 for 2WD.

I didn't considered the GM system as it seems to let the magic smoke go out very easily... A friend of mine, GM driver, used (smoked) 4 units on 4 runs !

The Mamba seems to be too brutal/wild, and nobody has seen the Tekin one yet.

GTB pro's : reliable, reverse drive possible (good for trainings), easy to find cheap

GTB con's : massive with his fragile fan, seems to NEED a fan for anything more than a 6.5, can make some glitches

LRP/Nosram pro's : looks more efficient (no fan required unless you use a 3.5), more adjustable (punch control mainly), some says it's smoother, looks better to me

LRP/Nosram con's : no reverse (why ? It's only a software thing), maybe less reliable (at least for the old versions)

Those are only bench and internet rumors, so I'd like to have your advices, specially if you have own both !


Thx

I keep talking to myself here

Anywayz, I think I am going to the LRP/Nosram route now. My question is : is it okay to use an original Sphere (not Comp) for 2WD with a bonded 7.5, maybe 6.5 ? Or would it be pushing it hard ?
The reason is I like the reverse mode of the original Sphere. It will save me some trips down the drivers' stand to self-marshal my car

its not illegal at the national's, nothing about it at all in the rule's. been over this a while back with paul worsley. reverse is fine to use at any brca meeting

According to the LRP Website

LRP Sphere Brushless #80500 is ok for
7.5t #50661
6.5t #50671

LRP Sphere Brushless comp #80700 is ok for
5.5t #50681
4.5t #50691

7.5t, 6.5t, 5.5t are bonded, 4.5t is sinitered (not that I have a clue what that means!!)

As for reverse (legal or not), I hate it, theres nothing worse than someone reversing into your path because they have crashed...You just dont expect it. I hate to make generalisations, but it tends to be people who are newer to racing and dont really consider other drivers

I run the Mamba Max and it's excellent. Really nice and smooth power delivery, good and controllable. You can set it as forward only, or reverse. Before I bought it I wondered whether it was going to be only good for 'bashing' but no, it's totally raceble - top notch.

Yes, but you can change the mode for Fwd/brake only, and I live in France and here nobody cares if you make the entire run in reverse
