Build time! Redcat RDS builders kit on the bench. 

I used a 3 racing magnet setup

Since I removed the dbag who orginally responded to this question from my channel I'll at least post something for everyone else. I'm guessing in the 4 months since you have posted this you have this figured out, but for those who may not know....Servo centering is done mechanically, and electronically. You need to adjust the physical linkage to get it as close to centered as possible. Mostly using the book lengths on the steering linkage that should get you close. The rest must be done when the radio is installed. You first must power up your radio/reciever and servo WITHOUT any linkage attached. Make sure steering trim AND subtrim are 100 percent centered in the radio programming. I also make sure endpoints on the steering channel are at 100%. Once that is done you can then attach the servo horn and see where you are at. Attach the servo horn with the radio and servo powered up so it stays centered as you attach the horn. If the steering is off adjust the SUBTRIM, not the trim as Mr Percival suggested. Use the subtrim to get the wheels pointed in the right direction. IF you don't have enough adjustment within sub trim to get them centered, then you must go back and work on the physical centering. Subtrim is for the last 5% of getting it dialed in. Physical adjustment of linkage is the other 95% - I should say this should be done with the gyro out of the loop. That adds a whole other level of complexity. But at least without the Gyro in the loop and you get everything straight you can at least assume the initial setup is correct when you introduce the gyro into the loop. Anywho sorry I took so long to respond, life happens. Happy drifting.

yes it does!
