Pulsating Motors
#1
Hello All!

I'm new to the Forum, am at work just now (break) but have a problem which I have never come across.

I have two possible solutions but everything else I have tried has not worked.

I was previously flying with Devo 10 and RX703a with no problems! But decided to move onto the X9D Plus and X4R SB.

So I may easily has missed something simple and I have a niggle that the solution lies with FS.

I haven't updated the tx or rx firmware as I bought both with European firmware.

And am also thinking lose power connection so gonnae change out PDB next.

Basically when I arm my quad by Aux 5 disarm/arm/failsafe the green led on, the motors spin up then stop in a perfect pulse rhythm 1 sec on 1 sec off. 1 sec on 1 sec off and so on, all whilst the X4R SB flashes from green to red and the X9D says RF loss telemetry loss, telemetry connection Etc.
Sounds like power problem.

Set up

Gravity 250
Naze 32 Rev 6c (Genuine)
Matek PDB dual Bec 5/12v
DYS 20A BLHeli ESC
EMAX RS 2205 2300kv
Graphene 1300mah 65c

(Run cam owl E600 vtx skyzone Goggs etc) not connected.

Escs were working fine and have been recalibrated.
Acc. Recalibrated
X4R is bound and solid green. (Sbus)
Loop 2500
Soft serial 1, inversion cli set. Telemetry on.
One shot disabled.

Min throttle 1050
Mid throttle 1500
High throttle 1980
Min command 1000

Stage 2 CL FS enabled (land 1200) I know!
V bat on
Curr on.
X4R FS set to Off!
Motors purr like a dream to every slide in the motors tab

Yes has me baffled have been searching for a solution for almost a month to no avail, and have been impressed with the Authors positive insight.

Thanks in advance for reading my woes!

Look forward to a barrage of trial and error that will ensue!

Dave .

Ps all above from memory can give additional info when home ?

Try to get the led solid green on the RX, maybe only power up the RX without the other wires connected and make a new configuration in your TX and look if that's working.
