5: Who stocks these things? most shops I frequent don't seem to stock "Neu" motors 
Thank you for reading my idiot questions  . Answers on a postcard to the usual address |
1: Something like a Castle Creations Mamba Monster Max with the 2200kV motor will suit you well, with a good amount of options for batteries and motors, as well as an excellent warrenty.
2: For 1/8 4S minimum is best really, this keeps the temperatures down (as higher voltage with the same power = lower current and therefore less heat). With the 2200kV motor, you'd be best to go with 4S. To use 5S you'd want approx 1800-2000kV and 6S 1400-1700kV.

4: It all depends on the length of the final. For 10 minutes, a 4S 5000mAh will finish easily. For 15 minutes, something like a 5S 5000mAh would be good, and for 20 minutes a 6S 5500mAh should do the trick. (Note, the motor will need to be matched to the battery, and the gearing too. Gear for 40mph using the calculator above).
5: You probably won't find a Neu motor in a UK shop, you'll have to ship one from America. Though Hacker motors are as good and are available in the UK - the price tag is a bit steep though for any of the really high quality motors (Neu, Hacker, Lehner etc).
