I'd highly recommend the Fusion exceed. I use the exceed 10.5 race, but am aware that they do a 13.5t for about £80.
I've had mine for several months in a buggy with a fdr of about 9. The motor and esc hasn't gone over 120F and the car does around 40-45mph.
With the Fusion exceed being available from the UK it's also supplied with a warranty.
PS- It's also a sensored setup and has numerous programming options including; Max temperature, max speed, abs, current voltage, ETC.. ETC..
