what size spur? I would gear for a FDR of about 6.7 to 7.0. that motor has some crazy torque. watch your temps too. if you're running less than 135 to 140°F, you are good. if you have any questions don't hesitate to ask. good luck sir.

Thanks for the info, i have a b5m buggy that runs on astro or carpet geared at 25 .i use shorty or sadlesvdepending on track ,both LRP (4700 the shorty 5800 the sadle). So i guess i should gear 27 or 28.....

hello, i follow your sugestion and got a Motorsports "Kill Shot Beast" Double Torque Brushless Motor (13.5T) , it will replace my speed passion mm 13.5. I hope to see a difference lol

Do you still have the 44.c nib buggy?
