Default New to electric got tasered!

hi everybody,
i post here cauze i m getting into electric after few years of nitro (touring and buggy)
when last july i both my first 1/18 caster racing i immediately realized that electric would be best for me.

now i m here trying to get some advice cause im entering touring E.

i ordered already a schumacher mi4lp btw the race version in order to save some money to spend on electrics just because i need almost everything (lipo, charger ecc..)
i would like to know if someone else has gt the same car and how it works.
it really looks very cool and fast to me, but i might be wrong.
btw what really attract me of this car is the specific lipo design...that s y i got it. (and even cause is not too expensive)

my second question is on motor, i would like to buy the speed passion cirtix 10.5T combo, for two reasons:
- here in italy can be found very cheaply around 100 euros,
-can race it in the 10.5t category at my home track.
i would like to know if some one tried it and how it goes, furthermore i m completely blank on gearing.
which pinion should i use, how many t, considering the internal gear ratio of the car, and the final gearing ratio of the motor (which both actually i dont know)

thanks for any suggestion u would give
and electric rulez!!!

For gearing, here are two links that have helped me understand. The first one is old, but it explained the math and why. The other is a way to calculate FDR.



Here is a link to the Mi4 thread as that will get you specific info on the chassis you purchased. I have a Losi Type R so I am no help with the Mi4 chassis.

I heard the driveshafts can be an issue on the race version of the mi4lp, so it might be worth keeping a few spares handy, or upgrading to the better ones included the more expensive kit.
