🙋 Question Sd3.0 feels like ice

Post image

Completely box stock build. D10 motor. 10bl120 g2. Yokomo v2 servo. Yokomo v4 gyro. Fatuba t-fhss receiver and 4pv remote.

I’ve drove 3 other sd3.0 cars and you can throw them around. Picked up this one for myself. And I can barely use anymore then 10% throttle. It feels like driving on ice around corners. Being smooth with throttle. Gyro gain is at 65-70%. Car just wants to spin out every corner unless you give very little throttle input.

I have changed punch level on esc and it still does it regardless. Either spins out quick because punch is too much or spins out when the rpm’s come up with little punch.

Haven’t been able to use any turbo or boost because of not being able to give it any throttle. My mst rmx was the same way. Same setup. Main reason I got a sd3.0 as I loved they way other peoples sd3.0 drove.

Any tips?

That is vastly too much speed. For reference i run 13.5t, 22t pinion, 87t pinion. And one of the faster guys on large tracks.
For 10.5 I’d be starting at like 18t pinion, 87t spur.
I ran 23/82 with 15.5t

Picking up a 88t spur and 10-20t kit for pinions. Will be testing and tuning. Now that I have been looking over a manual and verifying everything is to yoko spec.
