XRAY - Model racing cars

Hello.

Some help please.

Right, current set up, Xray X12. HPI Flux Pro 10.5 motor. Hobbywing xerun 2.1 speedo, Reedy 7000mah lipo batteries, 76 spur 41 pinion. Rollout of 74.5

I managed to finish 6th in the C Final on Saturday. My best finish to date this season. Clean run, handled well, and no big mistakes. However It seemed to be very sluggish with no real acceleration through the infield too compared to most other cars. I dont think I could get many more laps out of the car due to the lack of speed.

How can I get more speed? is it the motor? Gearing? I could probably be a bit tighter round the corners and a bit more consistent but I want to be faster, straight line speed.



Any advice

Sounds like you are geared too tall.
74.5mm/pr is more like 13.5 gearing.
try 65mm/pr or similar and see if that helps.

Thanks for putting this up. It helped me.
