It was me who you got into the bidding war with at the end of the auction . Congrats, looks like a really nice buggy, i bet it shifts with that Max8 combo in it!
The 2 servos mentioned above, the LF20 has more torque (20kg) but is a bit slower than the LF13 (13kg). I've just ordered an LF13 for my Kyosho DRX for £13, if you dont mind waiting a couple of weeks for it to arrive.
