Trim Handle stability on Hatz Classic
Posted: Wed May 29, 2019 7:14 am
Believe it or not after 17 years (part time) of course my Classic is getting ready for Phase 1 flight testing. I'll get right to it. The trim handle is built to plans and operates very smoothly. My question/issue is about how well does the handle keep the trim in position during flight. Yes there is a knob to adjust tension but the surface area on the end of the trim handle axle is not great. I've put a wrench on the bolt and tightened the knob but I feel the aerodynamic forces will streamline the tab in flight or even cause a fluttering trim tab. At this point I am about to remove the knob and put a nyloc nut on the bolt to tension the handle. Have any Classic builders modified the trim handle to provide better friction to hold the trim handle and trim tab in a secure position?
