Bought a Caster ZX-1 because it came with a 2.4G radio and the guy in the shop said that the 21 GO engine in it was popular and was quite good. Steering servo gears stripped after 5 mins on tarmac going slow and I didnt hit anything! Although my 2 year old was playing with the wheels when I got it out of the box! I have upgraded the steering servo to a 10kg 0.07sec/60 degrees digital servo.
After 3 tanks of steady driving I opened her up for a couple of seconds and she revved very high, I thought these things were supposed to be set rich from the factory?
Also the exhaust is very loud, would getting a tuned pipe make it quieter or even louder?
