有冇c hing 可解答彈弓硬度對車架之影響及車tire 之呎寸. 應用咩gear ratio. Thx
i play. At tc. 12r5. 7.5r. 6.6v.

Softer front spring for rougher surface.
Stiffer front spring for high traction surface.

in 1/12, you need to learn how to calculate rollout. here is the formula:
Rollout = Pi * (rear tire diameter) * Pinion / Spur

For [email protected], you can aim your rollout to be about 35mm
If you use tire size of 45mm and spur size 95, then your pinion is about 23 to 24 teeth.

but. My friend play f104 ，their tire粗好多. They use96 spur gear. And 36摩打gear

你行6.6v, 人地行7.4v, 你行細tire, 人地行大tire, 齒比緊係唔同啦!!!

Different motor need different gearing.
They use 17.5R, you use 7.5R... there is a large difference here!

try my recommendation. use 23 to 24 teeth first. then check your motor temperature. if it is cool (<60C), you can use larger pinion.

i am sure your 1/12 at this gearing will be faster than your friend's F1.
