My recent problem with 6 button CH product force feedback is solved, thanks to guidance from Liran_Bar and Matt NW.
All functions including force, perfect for all acft. except the fantastic I3D B1B and Dean Reimers F-18. They both will shortly after takeoff stop responding to the stick. Control surfaces flutter wildly, no control over throttle etc. They eventually spin into the ground. I have tested about a dozen other acft no problem at all. I am stumped, these two are my favorites. Doug
