Spirit System

got a 100a YPG ESC connected on aux1 on the spirit2
but engine no signal
the FBL is connected with a duo BEC from Mateck systems
6V to the RX end 8.4V for the FBL and servo's all KST
FBL works al servo's working but on aux 1 no signal for the ESC
on the software put the channel mapping to cannel 3 like it is on the TX Frsky X20.
disconnect the red wire from the ESC( power is running on the externe BEC)
some one nows the problen or give me a hint.
regards Martin

Hello,

please set Channel for Throttle to 1.

I am not sure what is your receiver wiring but in the most cases it is Channel 1 in the Spirit.
You should see throttle channel movement in the software in any case.

reciever is a Jumper R1 sbus 16ch
