Scale 1/8 buggy

[nativepaul]

well as im trying to do this on a shoestring I have the motor and cells allready so the only variable is the gears, I hope thats enough. With a 44t spur and 16t pinion, I get 33-40mph from 1-1.3v on the lightnings 4.58" tyres. That seems good forf the off road set up.

The rpm is well under 35k tho at 25-29k, will this make me more likely to smoke anything?

What about for on road? I looked at on road wheels and tyres, they use the same wheel but are lower profile so they are smaller diameter, thus if i just fit road tyres to run in the street it will be slower than off road, so I will need to swap pinions with the wheels.

Can anyone recomend a rubber road tyre that is decently grippy but very long lasting to suit my budget over time, and tell me the diameter so I can speed calc it.

If I should gear for 35mph off road, how fast should I go on road, and still be able to run hard for the batterys duration, without smokeing anything?
