No more modifying your servo! We’ve now redesigned the original BMS 210 servo to include a feedback wire straight from the factory. This wire is used to accurately determine at which angle the servo is positioned at all times. The wire plugs in to the flightcontroller and the information is used by the latest versions of the TriFlight code to vastly improve the yaw performance of the tricopter.
The price for the new RCExplorer 210 DMH Feedback servo is the same as the previous non feedback version.
Note: You don’t have to use the servo feedback wire. The servo will work just like any normal servo if you don’t connect the wire.
All electronic kits now comes with the new feedback version of the servo.
So very cool! The servo feedback wire is a pain to solder to the standard servo so this is a life saver 🙂
Any hope of stocking the replacement gears for this servo? BlueBird gear set #33201?

Terje,
Where can I find the details of this mod ?
Nice work on the Pins !!

Best pictures can be found in the build log of the V3.5: http://rcexplorer.se/projects/2016/01/tricopter-v3-5-build/
Thanks
Thanks!
I almost could have guessed that if I’d opened up the servo. It would also work on a potentiometer servo, right? Just put the sense wire on the middle lead of the pot?
Is there a way to calibrate the start-middle-end voltages of the sense wire? Or does it just assume it is 0-2.5-5V?
I meant to post this under my comment bellow, but I think it is relevant here too.
You need 0-3.3V max. It automatically sets the voltage range during setup.
Wow! I’ve never imagined that’s possible. Will be getting a couple instead of trying to modify the existing ones. I’m so relieved! (:
Yes, I feel the same way. Was not really looking forward to that mod. For the v3, I opened the servo case up to solder on custom cut silicon servo wires and that was enough of a pain that I don’t look forward to doing it again…
Is the wire long enough to run through the arm on the larger Tri or will you still have to solder your own length on to avoid splices?
No, but it is long enough for for the mini tricopter. On the large one you’ll have to splice I’m afraid. I have ordered 4 wire extension cable for the V3.5 that should come in in a two weeks or so.
I see the 4 wire extension will work well for new FC your releasing that will be soldered on now!! Great job David!!
Hahaha I was the first doing this OEM style.
So I notice when I click on Triflight there are updated versions are these both for mini and large, should I be updating to these new ones?
I’m interested in adding the sensor wire to an original BMS 210 servo. Is there a web page which describes how to do it?
Yes, it’s described in the tricopter v3.5 build log. Just scroll down for a bit until you get to the servo part.
