I really want to compete in local 1/10 rally competitions, but my Himoto car doesnt pass the scale requirements. I want to to put my electronics and engine (except broken servo) onto Tamiya TT-02 chassis. I need my build somewhat competitive with XV-01. I have a brushless KV3210 engine, and as i know, key to compete with better things is proper gearing. So i want to squeeze the most out of my engine while keeping the car good for rallying. As I calculated, stock 22/70 gearing = 26 KPH. My 19/48 gearing = 32,7 KPH. Random internet guy's reccomended 29/64 gearing = 37,5 KPH My questions are: Can my gears be compatible with the chassis? Do i need to buy exactly tamiya-branded gears? Most important: Can you recommend me the best ratio for me? How do I know if my calculated "perfect speed" ratio will damage the diffs? Well no one stops me from getting a 55T pinion and 50T spur gear milking them 91 KPH. Type of races I want to compete in: This Toyota looks like it has too much power... Maybe gear ratio for better steering and acceleration, not top speed? Idk I'll be on race here tomorrow. Looks like this car (1:27) is too grippy... I actually plan to run my car both awd rally and goof around 2wd drifting SIDE NOTES: I know i'll have to "modify" the chassis to be more rally-acceptable and buy some hop-ups like proper shocks and bearings. You're welcome to suggest more things I could upgrade.
