Could anybody suggest me what kind of spur and pinion gear to run with 21.5 motor, no boost with track of the picture?

Best regards

No, no. I wont be attending this event, by the way, where is it?

TC 21.5. If you're running a 14 mm rotor you're going to go for a big rollout.

What's your motor timing settings?

What's your current gearing? I would aim for an FDR of around 3.5 and work from there.

Maybe i will buy a Muchmore 21.5w later due your concern of spin out with 14mm rotor, despite i will use ip4800 shorty lipo, they are lower punch but quite lightweight
I hope use 90/48 but due i didn't still buy 49 50 51 and 52

If you can, I would suggest buying an ORCA 21.5 - Awesome motor! You can order one from Kamui rc. I would set the timing to 1.5 or 2.0 mm past the timing mark. This motor is a beast!

Forget it, the time is up, in this moment i just want a drivable car, if as you say 14mm rotor is rollout, which is unique rotor by TRION, why i still need a beast?
Do you think i still buy 49 to 52 gears?

Best regards

Ignore my rollout comment.

Are you racing right now? When is the race?

A 14 mm rotor will have crazy torque which is good for this layout. Don't change your motor. Remember all that torque might cause the rear end to lose traction. I would just pick up some extra pinions and always temp the motor. Each pinion change take the car out on the track and run the car for a minute and temp the motor.

No, 27 to 29.
But is strange, i am inexperience with 21.5 due our rules is 13.5, i have hear even F1 run with these motors in Japan but still OK, that's why i bought these.

I saw the same race of last year, they still ran 17.5 but the car look likes quite stable, so i ignore problem of torque with 14mm but 21.5 motor.

Ok, i will, thanks.
Sorry for my forgotten, in fact the race will be in Chubu Airport, Nagoya.

But want ask 1 more think, due c your concern of my car will rollout, if the car is going harder to drive, just increase FDR(EG: 3.5 to 3.6), isn't it?

Because with my boosted racing experience, is different than no boost, if car is too fast, should decrease FDR(EG: 6.0 to 5.9), isn't it?

Best regards
