Best servo you can buy and it's available from Trakpower: Ino-Lab HG-D261HB
It has carbonite gears and has withstood significant abuse yesterday at Wycombe combined with my XRay M18 micro servo saver.
All I can say is this thing is rediculously quick and in my opinion probably the best servo you can run in one of these cars.
Digital coreless
0.06s speed has to been seen to be believed!
Best of all these puppies only sell for £35-£39 and can be bought from your LHS. They also do replacement gear sets and covers if needed.
