No throttle response
#1
Hi All,

I just received a Newbeedrone BeeBrain Brushless. I have it bound to my Taranis Xlite Pro in D16 mode.
In Betaflight, I see that all sticks are working properly. The ARM and Mode switch ranges also seem good.
However, when I ARM the quad, the motors do not spin up and there is no throttle response. But, if I move the yaw, roll and pitch controls, the corresponding motors are spinning correctly. They do not spin when the quad is not armed, which means that the quad is indeed arming.

I can get into the OSD menu, by the holding the left stick in mid/left position & right stick in mid/top position. I can also navigate the OSD menu with the sticks.

In Betaflight receiver tab, lowest throttle value read from the TX is 995 and max throttle value is 1990.
Betaflight is setup by default as Stick low throttle = 1075 and Stick high throttle = 1900, which seems ok.

Note that I get the exact same issue when bound in D8 mode using an MPM module on my Xlite pro.

I am at a loss as to what could be going on.
Any help will be greatly appreciated.
Thanks.

I have the same problem but I think it is something else.
P/R/Y are working, Throttle not.
Turtle mode is set on AUX3 en is working.

Any other options?

In the Receiver tab are you seeing the throttle bar moving as you raise and lower the thottle stick? If not, check the same on the CHANNEL MONITOR page of your transmitter.
