on the LRP website it should give the sepcs.

here is a direct link to the page

I had my 1st outing with the Sphere Comp and 3star motor yesterday at the Mid-West regional, plenty of grunt but the top end was not great, i think it was a little undergeared but i was playing it safe with it being wet and the grass you may pickup and slow down the car.

In practise the car stoped after around 3 1/2 minutes, dead as a doo doo so i guess the speedo had got to hot and cutout but when i touched the heatsink it was not to hot. After leaving the car for a good 20 minutes checked the car again, just a blue light on the speedo and nothing else so i guesssed the speedo had gone. Which with the weather i did not try another speedo and called it a day. Meeting was stoped after 2 rounds due to the rain.

When i got home i checked the car out, still doing the same so i started to change items, first the receiver, switched on and worked fine, so i can only guess that some damp or water maybe of got into the receiver, but really happy that speedo and motor are ok.

Was geared 16/78 on the Slim4 so next time 17 or 18 i would guess.

Btw paul i got the speedo and motor from Dom at DCracing.
