[footey]

hi im going to be fitting a gtb brushless system to my new ride its got a 6.5 motor and its a standard geared car any help with what pinion i should run it will be a indoor car only cheers

[footey]

Hi footey, I don't have to answer to your question but I'm interested to see how you fit the brushless system into your BX. Take a photo if you can, I plan to fit brushless myself into my BX in 2007.

This is the second way I put mine in. I first ran the wires around behind the spur and under the upper brace similar to the way Masami did his. This was much neater but was a pain in the butt to work on, running the wires overtop allows me to pull the whole works out without soldering.This allows me to put in a brushed system within a few minutes.


I also put two fans on to help keep the unit cool but I still have a hard time keeping it cool. I am using the stock spur and a 12 tooth pinion on the Neo 4 star and it is stupid fast. To get the correct gear backlash I had to file the slots for the screws a little longer. I am just maxing out on speed as it is still accellerating at the end of the straight. If anybody uses this setup I had to really dial down the speed control to get traction offroad and used the throttle exp.to get more control on loose surfaces.

Looks like it was pretty hard to get the brushless system to fit in there, I also notice that you’ve had a go at blocking up the holes to the rear diff, seems like a good idea.

man, that must be insanely quick if you are having to gear down that far! madness

[Southwell]

Seems insanely undergeared to me, can't see it needed that small a pinion, might be why it's getting really hot...but then again i don't own a bx lol.

[PaulRotheram]

have you tried gearing up instead of down? a 12 pinion seems very very small for any car :-o

you could possibly be very undergeared hence the heat problem? what does the LRP manual suggest?

Hi you all, this is my first post in this forum, I came from Spain. As you may know the summer here is quite hotter than UK and we are not having too much troubles about overheating (sometimes there is a thermal cut off, but nothing dramatic) while using a fan for the ESC and a gear ratio around 11 with the Novak 4.5R, wich is similar to Neo 4 star
