My son runs a 418 in kit setup, FDR gearing in the 8 region (according to table in manual to the 6.5T LRP X20 motor fitted), LRP Flow speedo in default settings.

Well, how do you know how to gain more top speed, play with gearing, speedo timing settings or both?
That gear is too short
Unless you are running on a tiny indoor track

8:1 is about right for a 4-5t motor
Gear up, try around 6.5 to 7:1 for a 150' straight
Leave timing at default on motor, use Flow timing to fine tune how hard you want it to hit

temp at 4m
