Servo to Shaft Coupler

Hello,

I am in need of a servo to shaft coupler that will connect a smooth 3/8" shaft to a servo. The servo I have is a SpringRC SM-S4303R Continuous Rotation Servo (pololu.com/catalog/product/1248/pictures). My question is which coupler do I buy? I noticed part number RB-Sct-61 for Hitec and part number RB-Sct-78 for Futaba. Will these work for the servo that I have?

Thanks very much!

Hi,

We do not offer the SpringRC servo and cannot tell you if it uses a Hitec / Futaba / Other spline. Since there is no mention, there is a good chance it might be “other” at which point you will have to improvise.

Sincerely,
