Thanks for replys nikos
On another note ran both 2wd & 4x4 today in Sydney at a new track never ran before.
Losi 22.20 17.5 stock 69/37 gearing and esc came off at 26'c and motor 32'c
Xray XB4 17.5 stock 72/34 gearing esc 28'c and motor 38'c
Broke a ballstud on the losi & Need more setup work.
Never ran the Xray before & it pulled away out of corners but by end of straight they were catching me.
Got 5th in first final & 8th in second. Had that many people take me out was tempted to start swinging punches.
