I was looking to get a brushless system for modified indoor but it seems lots of the racers are having problems with the thing overheating. Does the fan on the sphere really make enough difference to stop it shutting down?

So which motors have the new style rotors or whatever? if i was to get a 3.5 novak motor and a sphere speedo with a fan would that be an ok combo for modified? i would not be running the 3.5 at max power.

If you are not going to run the motor at max power then you should get a different motor. A 5.5 would probably be enough for indoor. I run mod with my 5.5 and 4.5 outdoor and the 4.5 is somtimes a but much for some tracks. I think the 4.5 would be a bit much for indoor depending on the size.

The 5.5 has the updated end cap (if you mean the endbell) and the updated rotor.

Howdy,

I can't comment on your 1/12th, but I have some observations which may be of interest regarding your 2wd off-road. I am currently running a Novak GTB/Velociti 5.5 combo in my T4. I've had it about 8 months. For anything other than a very large track it is simply too much motor. At our home track I can only make full throttle generally in only two or three places on the track, for a total of probably a couple of seconds per lap. On a tight layout with low traction, it is so hard to get the power down I sometimes can't even lose the stock guys :-(

I knew the 5.5 would be over the top, but I'm not real serious about my truck racing, so I went for the overkill/fun option. If I was fair dinkum, I would go for the 6.5 (max) or probably the 7.5 for a truck. For a buggy, the 7.5 I think would be absolute tops. As a comparison, I am often racing close to another T4 guy with a 12x2 cobalt, and I can totally roast him on the straight unless I make a mistake on the entry corner.

Problems? The cooling fan blades all snapped off in no time at all. I ran for a month without a fan, then mounted a AE fan on the chassis next to the GTB. If your buggy is a B4, then I can advise that the GTB won't fit under most shells unless you remove the fan. My experience is that the system is totally fine without the fan at all, and you can simply pull it off.

I can't comment first hand, but I would be very surprised if the fan were required with 4 cells in a 1/12th.

In the the T4 I can easily do 8 - 10 minutes runtime on the track with good 3800's.

Personally I love my GTB/Velo so far.

Yeah i meant the endbell but thought it might have been referred to differently than a brushed motor

Thanks,

Well the endbell on a brushless motor is were the sharft exits the motor. The motor doesn't have the solder tabs like on the 4.5 if that was what you meant.

Well, if it was me. I'd get the GTB with a Velociti motor, but I'm a little biased I suppose.....

Are there any improvements to the GTB to handle the hotter motor?
