The OH-58C that I maintain for the local Sheriffs office has a pseudo force trim system. It has a magnetic brake that the pilot can engage and disengage via cyclic grip switch to position and hold the cyclic in position. The control box/actuator is located under the copilots seat pan. And this aircraft is stock from US Army surplus sans a paintjob, a SX16 light and some mission equipment.As for slop in your xmsn mounts, it can hide in a few places. Ive seen the dogbones have seperation at the elastomers that wasnt visually apparent and went undetected till the suspect end was put in a vise and the bone was flexed. Another problematic area is the transmission restraint under the driveshaft. It has 2 bearings in the end that wear out constantly and can cause some shifting and the other end of the restraint has a sandwich of elastomer and metal that can debond, but that isnt as common as the bearings wearing.I have no idea if these could be a factor, just passing some knowledge along from 15 years of 206 series wrenching.
