Question: Servo Savers?

[Resin_Smoker]

I'm interested in using a small 25 spline Servo-Saver on a Tricopter's servo mechanism. Not something that's commonly done for multi-rotors so i thought I'd ask here. The Saver needs to be robust and allow for low latency to help prevent Tail-Wag. Thus far I can use the following models of Servos with my setup:

BMS-385D https://servodatabase.com/servo/blue-bird/bms-385dmax
BMS-210D https://rcexplorer.se/product/blue-b...-210dmh-servo/

What type Servo-Saver would you recommend for my application and why?

Thank you in advance!

Interesting.... hadn't heard of these before (didn't fall down the surface RC rabbit hole yet).

Would be interesting to see how it performs on a tri... perhaps a visit to a local RC shop that has lots of car experience could get you some hands-on with different types to see what feels right.

Or you could get all mathy on it - which is the right answer for human piloted aircraft but this is hobby level - give it a whirl and send pictures/video!

You would need to provide more information on how the servo is mounted to the control surface. The RCExplorer Baby and Mini Tricopters for example have the servo directly mounted to the tilt mechanism by design to minimize lag and slop. Perhaps what you are interested in is a different tilt mechanism altogether.

Cheers!

I would think after using them on cars n trucks that the added height of the saver would not work out well for alignment on a tail rotor assembly. There would have to be some definite modifications I would think. Also to get the saver to work properly with the amount of torque that could be applied moving the heavy motor assembly and the inertial forces that comes with it I would think the adjustment screw to tension the spring would have to be so tight it would more then likely defeat the purpose of it to begin with.
