The real world Cabri G2 helicopter has a cyclic trim switch that sets trim for pitch and bank. My heli model by MP Design Studio works a treat with P3D. P3D has settings for elevator trim up & down and aileron trim left & right: these key assignments work perfectly for fixed wing aircraft. But I can't make them work on my rotary wing Cabri G2. This is also the case with other helix resident in P3D.
This is a great nuisance because without the ability to apply trim one has to maintain a constant force on the cyclic during flight.
Please can someone suggest a solution?
