Hi All,

i'm setting up the parameters for APM2.5 arduplane for my HobbyKinf FPV.

Anyone has the same airplane?

I'd like to doublecheck my parameters (I will fly in a good wind 25/30 km/h)

Any suggestion? (the airplane is similar to skywalker 1680 FPV platform)

Thx

Marco

HI all, thanks again for your help and support, my last question:

in apm1 i covered the barometer with some cotton pad, and worked fine.

I wil use now the apm2.5 that has its own cover, shall i foresee to protect in some way the barometer even if not ditectly exposed the air flow?

Thx

Hi, just out of interest in the comments on the plane: Can you give me an exact link to the plane model?

Thanks, Soren Kuula

The roll pitch P values are only 0.4 as default. This is too conservative for most platforms. Set them to 0.8 or 0.9 and it will be much better in stab mode.

I tried to use this airframe, but it was terrible...

APM default settings are a good starting point, but i found even with a decent motor and 4s battery, this plane was under powered. Its heavy even before you start loading it up with gear.

Good luck and have seen other people use them, for me it wasnt a good platform and I switched to a funcub, which is working very well.
