Ok, I just tried arming by using left rudder and zero throttle, now it arms on my Spektrum 7, but the manual says to use right rudder to arm, and left to disarm..other way around for me!

Still not able to discover why there is no aileron signal..I am perplexed by this, no internet or RCG searches are showing any resolution to this issue (as far as my searches have shown anyway) I'm unable to go any further until I get this sorted. I built this tricopter from scratch over a year ago, I couldn't get either of my two preceding KK boards to arm,whatever I did, so was pinning hopes on this version working out for me..

To see this on ARM was a good sight to see! (for me anyway,lol) Awaiting advice..

TIA

Check the soldering on the aileron connector on the board. Also, swap two cables over to eliminate the aileron cable between controller and receiver.

Did you perform a receiver test via the KK2 menu and confirm that you channels are changing the values in the menu and that the channels are being registered in the right direction, left/right? It sounds to me that one of your channels is reversed being that you are arming in the reverse direction.

Thanks guys

First of all, I swapped the aileron and elevator cables at the RX, and tried again. When moving the aileron stick, it shows up as working on the LCD, so looks as if there might be an issue with the soldering...I took the board off the frame and flipped it over to see the soldering, and it look as if the soldering blob (upper right on the board) connects with the elevator connection on the outer board edge pin..

Am assuming this is the possible cause, and that I need to scrape the solder bridge out? Just want to check with you before I go ahead..

Sorry about the pic quality, this is from an old cell phone.

Not so sure now...I found this pic of the board, and looks as if the bridge soldering on the outer pins is normal?

Will the debug mode reveal anything regarding my aileron non- signal do you think?

This is so frustrating...Had to wait over a month for this board as they were OOS at HK when I ordered..

I just want to fly it!!

That is just all the ground pins connected together. Normal.

I've just checked these too on the board,and all were ok, except for the rudder, which will explain my arming issue..Ran the motors in armed mode with partial throttle (no props) after calibrating on the board, when I tilt the machine, you can hear the motors speeding up and slowing down, (forward/back) also can hear the motors speed up/slow down in roll mode, tilting R + L.. Still says Ail no signal on my LCD..

Do I have a bad board, or ( hopefully) have missed something else?

I can't be alone with this issue can I?

i didnt read all your posts butt i see you have dx7 spektrum

check if you tx is set like this

TYPE SELECT: acro
MODEL NAME: whatever
D/R SWITCH SEL: individ
WING TYPE: flaperon off
v-tail off
delta off

INPUT SELECT: aux2: 2p sw
aux2 trim:inh
flap: system
flap trim:act

THRO RECOVERY: inh

good luck

May seem silly, and you may have already done this, but check your connector on the board for ail. The pins are sometimes a bit wide, and the connector misses the inside pin. I did this once, that is how I know...

To be sure the right motors are speeding up when tilting another thing to test is...

install your props, bring it out side step back 10ft. Your muti rotor well not lift off until you are giving about 50% thr. Arm the board and give about 25-35% thr and bank your AIL left and right to see if it is sending the right signal. do tha same with your yaw.

As for your arming/disarming. What is your rudd channel on your radio? nor or rev?
I use a 7s and mine is Normal

yes but what happens if i lower P gain

i make pirouette and when i release rudder stick quad goes about 40 degrees more left or right depends where i move rudder
does not stop immediately

Thankyou! I just checked it, and is already set as you described, so another variable ruled out..Also swapped one of the male/male board to RX leads in case one was substandard, aileron still says no signal.

Thanks anyway!

Rudder setting is now on Normal. Will give your suggestion a try outside tomorrow (if the rain is gone)
One other thing, my rudder servo isn't moving, and reads 5 on the receiver test, the number doesn't change when moving the stick r to l.Obviously this needs to work before I go outside. I have an almost full 3s battery on it, but voltage readout says zero on the LCD...
