Way better using 14x4,7 vs 14x8. At least capable to increase gain 20% more, a good signal. Its time to test other airscrew values. Thanks.

You may be right. Just now I' rearming some apc 14x4,7 to see what happens.

Im having some troubles setting the right gains on a skyjib octo with axi 4120/20 graupner 14x8 and CC phoenix 50. Seems like some users ha succesfully do it with some differences: turnigy plush instead CC (with multicopter firm), 15x6 Soar vs 14x8 graupner and hexa configuration instead of...

6.5 kg + 3.5 kg or 6.5 total? 140F seems no to be so high imo for 6.5 kg tow but it deppens on your weather temp outdoors.

So the trouble on esc outputs 7 and 8 has been solved by firm for all wkm units no matter how old they are? you know that before or you simply has bigger balls than others and have had good luck?

Was that done with modified/new wkm unit? (the one with same resistor values at each output) or it was done with an old wkm model?

Your low thr tx signal is higher when passing through the HFP than directly fitted to ghe rx. Thas why you need to do the above procedure in the right irder. you can check your esc connectim the directly to the rx and trying to arm with the thr stick in the middle possition. If ghe still...

Assuming your running 4x firm. Did you set your tx according with the HFP setup program to achieve the max-min values and later calibrate the escs to match them for the availble range?

Right, both boxes ph and rth checked at rth. Temp compensatiin is refered to the first processor (switch in position 1) of the flying board not the gps one as it corrects temp deviation of accelerometers which are placed in the base board.

Im using it with HoverflyPro and axi 2217/20 without apparently troubles. What are the problems you found.?

Thats not really true. I'm using it on a CX quad and on a AD8 coaxial octo with success.

You can actually do that using a eagletree and bypassing one esc signal wire throught it to record the thr position along an entire flight, no?

Could that mean there is a delay between orders executed by the 1-4 engines and the ones executed by the rest? may be a x8 configuration are less susceptible to this problen as it has the first ones in one floor and the rest in the other.

Not sure but maybe thats why I feel the fore-aft stick orders are not perfectly straight like some engines reacting a little faster than others.

And finally?

May be each wkm has an expiration date like yoghourts. :highly_amused: I noticed the same lack of gps lock with the octo days ago under shoft wind conditions and at +10°C.

acks about three FET lost the varnish consecutively and not all at once. That happened in two fets of one engine and one from another. Engines never armed nor worked. Still waiting the results of what happened to know if it was my fault. That was using a Hoverfly Pro but dude it has any...

What trouble do you had with the herkules. Have had one with puffy lines close to some fets apparently for no reasson.

Just comming back from the garden after flying two bats using the max disturb gain value allowed, 200%. I' m not sure but seems to be better, not a stable flight for filming unedited but way better handling high wind gusts. To be true it was a difficult test for the wkm. My garden has some hight...

I though before about the yaw control related with the other axus stability. The only way I found to get a reassonable yaw stability on low gains (about 140%) was using big surface airscrews like apc vs. Graupner and others. If you are right and wkm doesnt like big blades then we are arriving to...
