Hi, a time ago you said this:
I am using V1.24 of the firmware and with my Spektrum DX6i and OrangeRX I had to reverse the throttle and aileron channels

i have also a DX6i and a HK Ra61E ( clone of AR6110E) receiver and had to reverse throttle also , what i found out today was very strange and scary,
may be you can test it also rcjose but be carefull if you test it, the best is to test it on the ground and remove the props !!!!!!!

I was flying , an other pilot asked me if this is failsave , what happens if you lose radio contact , i said lets simulate it and by switching off the DX6i , i brought the quad at higher level (because i would expect the motors would stop) and switched off the DX6i, yeah no failsafe the quad disappeared like a rocket straight up into the sky with full power, I switched on again the DX6i immediately , and could control the quad again , thanks to DX6i "quick reconnect" feature

you know with firmware 1.22 no throttle reverse, only with firmware 1.24.
Dont know if that what happened is related to a reverse throtlle??
Note: binding of receiver happens with low throttle of course.

OOPS i think about it just now : i will do a rebinding of the receiver , i cannot remember if i did this after setting the throttle to reverse
a shame if i forgot it
I had a similar issue with the quad on the ground but with my Turnigy 9X which has failsafe on. My TX LiFe battery went too low while testimg the quad and the TX turned off BUT the quad motors kept spinning. I wasn't at full throttle and the quad was still on the ground so I was safely able to disconnect the main lipo. But I can only imagine what would have happened if the quad had been hovering in the air!

i thought the 9X had no failsafe??

how do you set it? put stick/switches in failsafe position and bind the rx?

You're right, it does not. Only 3-channel HK receiver has FS on 1 channel. If you want FS then need to install FrSky module into T9X (like I have).

I see others answered Techasist that the soldering was ok, i just checked mine but is a 1.31 so it has a chip of some sort in that location between the SMT stuff.

Checked my brothers which is a 1.3 and his solder connections all seperate but they are connected electrically, as I did a con check with a DVM while looking at Techasists picture.

This was before i read the replies obviously.

On another note got the guts to try a flip or two yesterday, X400 RTF, FF 1.24 in 3D mode.
Works fine, does not drop to far but not as crisp as with Timecops port from what I see. Took a deep breath before first try though.

Will get round to flashing it with Multiwii at somepoint, may just build new one to use that though as I got a Naze32, motors and ESC's.

Success!

Thanks to all for your help.
I reflashed 1.24 and did RC and motor calibration.
Motors now spin perfectly.

As mentioned previously, servos don't work on PWM outputs 3,4,5 and 6.

G,
Try this: Multicopter checklist for yaw issues 101
Do you get good yaw trace response in the ZN app?
Cheers,

After that I saw that you had to take pwm-output 3-6 and not 1-4.
Then all motors worked.

Still having the eternal spinning-problem.
Can't seem to get that fixed.
Once in the air it yaw's to the right forever on and on.

pity, he has killed the board http://www.multiwii.com/forum/viewto...tart=10#p14807

with the FF boards, it is gradually running out!
on ebay there are only still four sellers from Hongkong!

good outlook for your business

Chose PWM in motor test tab and saved. Powered FF down and back on.
I tried to connect servos to the PWM 1-6 output and armed the FF board.
No success.
