Re: B4 gearing
Hi Neil,
I think that the Nosram Storm 3 Star Motor was the first Generation Brushless Motor that Nosram Released
I know that the General Gearing for a new 7.5T(Sintered Rotor)Brushless Motor in an RC10 B4 2WD Buggy would have a FINAL DRIVE RATIO of around 8.8 (Spur Gear divided by Pinion x 2.60)
This would be a 78Spur/23Pinion...........but if your Buggy is still running the Standard Kit Spur Gear, it would be an 81Spur/24Pinion.
Due to your Storm 3 Star Motor being a couple of years old, its very likely to have a 'Bonded' Rotor........this would mean that you'd probably need to go down atleast 1Tooth, from the above Recommendations

Hi dean,

yes the motor is an old one but hope it should be ok for me as a first time 2wd buggy racer, last buggy i raced was a cat xls years a go when they were new in northampton.
Thanks Neil.
