Problem with KK multi Black

Since I put the KK Blackboard on the quad it's been horrible.

I started with V4.7 in X config
Tonight I've re-configured and loaded V2

The same problem exists in both versions.

From power on, gentle acceleration produces a stable hover, all gyros working correctly and very stable.

Any increase in throttle and it veers off left. The more throttle the more violent it veers off.

Now this is the bit I really don't understand...

After its had a jump left the stick centres are way off - I have to hold in 80% right stick with 40% back stick and a load of rudder to get back into a hover.

It stays like that until power off - power back up and really stable again sticks at centre.

The problem is consistent and happens every time any amount of power is applied.

Suggestions would be welcome - I've been fighting this for a few weeks.

I've been through the TX and checked the output monitor for mixing etc.

Sounds like posible loss of left motor power. Try swap out of left and right motor's and esc's, see if this changes direction of (jump left) if it does then narrow it down by only changing one item at a time. Good luck and keep smilin.

Shouldn't the gyro compensate for this ?

I suspect a faulty gyro - just can't work out why it only shows after a climb

I have not a gyro fail like that myself. but have had both motor and esc lose power after I give it a short burst, with motor it is usualy a damaged winding and with esc, I have not been able to repair but I understand that it can be a fet.

This might not be your problem, but cost nothing but a little time to check.

keep smillin

Stop assuming so much and start trouble shooting. All you have to do is to swap the hardware (motors and ESCs) from left to right and do another test. Very simple and will answer a lot of your question.
