Electric/ Gearing Advice

[jackeltrader]

Hi,
I have just taken delivery of my 1st electric 1/8th an xray 808e! I cant tell you how excited I am to build the car and run it but its gonna be a long road as I am coming from 1/10th off road background and I am having a nightmare choosing electrics/ motor/ batteries.

Rightly or wrongly I have chosen a Hobbywing 150a speedo with a 2200kv motor. I know the motor maybe too much for a buggy and I'm quite prepared to get a smaller motor if required such as a 1700kv - any advice would be great. The biggest thing I cant decide on is cells...I was going to get a set of nanotechs - 4s 6000mah but this is a soft pack - I run nano techs in all my 1/10th cars and are really great!
My main question is after spending a fortune I don't want to blow the car up by cooking the motor or cells so can anyone give me any advice as to what power cells to motor and pinion to run?!? I will be racing at KRMC, Herts now and agin and fairlop so descent size tracks with run times of around 20mins max!

I know I have asked a lot but just want to get it right without finding out the hard way if possible

Thank you very much - over & out
