Any idea on how the fan is mounted by screws on the Sphere heatsink? Is it a new heatsink? Thanks.

I think the heat sink is the same heat sink that comes with the set. you can either drill and tap the heat sink or you can use plastic bolt (like Novak GTB) that will be anchored in between the ribs. another option is for you to create the bolt boss using shoe goo.

i have a lrp competition sphere and it shuts off under load,has anyone had this problem?i have sent in once and the new one does the same thing.as far as i am concerned the gtb is a far better esc,i have ran one all indoor season and havent had aproblem,the lrp has not even been in for one race.seems lrp should work on their quality a little better

OK...What motor, What final drive ratio (or Roll out), How big is is your track, what car are you running? This info will let us know if you have a problem or if you did something wrong.

flat oval track 200ft runline,4300 motor,2.55 rollout.also on same track i ran gtb,4 star lrp motor,1.75 rollout no problems at all.this is the second speed control just out of the box that did this.the winning car in 4300 was a gtb,4300,2.65 rollout and came off the track at 145 degrees

Are you sure you didn't wire anything wrong? Any short? Once some wires were grounded on the chassis and the Sphere shut down as soon as I gave it throttle to prevent it from burning up.

I am happy with my Sphere.

If my math is right you are MASSIVELY over geared with the 4 Star. A Reedy 4 Start is like a Velociti 5.5. Your roll out should be less than 1" with a 4 star on a track the size you run on.

adrian the motor came off at 155 degrees after 4 minute run.that is what we have been gearing the motors to come off of the track

You need to gear for lap times. Temp is secondary. I still think you are way over geared. You are gearing a 9 turn mod like a 19T.

How do you go about getting a a lrp brushless T-shirt ?

is the LRP sphere comp and Vector waterproof?

I didnt want to use it in the rain the last time i ran it as i wasnt sure?

one thing I like about the LRP is that it seems to have less wires
than the other brushless systems out there. I hope they will include
a fan with the unit just like the pics posted above.

Can't wait to start racing elect again.

Would it gain any benefit if I replace the stock capacitor with a higher voltage one ? i would run my Sphere competition with 4 stars on a touring with Lipo .. if so, do I need to solder off the stock one or ...... ??

Pls advise, thx in advance

Where can you get the plastic bolts??

I wouldn't use plastic bolts unless they have threads to go into. Plastic bolts can usually be obtained from electronic part retailers.
