R6108sb will not bind to 12 or 14ch, mult only

Was RX binded again? With R6303SB it works without any problem.

Offcourse that's a newer receiver. R
6108sb will only bind to mult, trust me

Velocity, have you got a solution for this?

Nope, tried 3 receivers, all the same. What seems to work is a Frsky receiver but I will never fly those. Original Futaba only.

Yesterday we have received receiver from velocity90 - thank you very much.
We have replicated the issue with MULT and MULT2 fasst modulations.

After investigation it is clear that the problem is in the receiver firmware. What it does is sending the throttle data so that target value is not reached immediately, but for a few miliseconds it sends an incorrect value (approx /2 of the target value).
So when you want to reach for example 1600us it will go to 1350us first (stays there for 14ms and then jump finally to 1600us) when the initial value was 1100us.

This behavior is happening only for the first time you disarm throttle hold. Everytime receiver is restarted the issue appear again (but always only during the first disarm).
The unit is simply fast enough that it reacts for such strange behavior.

So it was necessary to implement hack to make it work as supposed.
Correct solution is to fix the problem in Futaba devices, but I doubt it will ever happen.
I guess that the issue is occuring only with a slower modulations. With faster data are transmitted always correctly.

Our testing firmware is ready.

Great to see you could debug and fix the problem. My assumption about a strange receiver behavior wasn't to bad at all.
It's fantastic to see Spirit Team to even fix 3rd party issues in Spirit, real Customer focus, thanks a lot.

Tested the new firmware. Problem is gone Thank you Tomas
