I did experience the same. I standard KR2S cannot be trimmed. It will keep the trim speed for a maximum of 30 seconds before it will climb or descend and not return to the trim speed.... Cheers Christian OE-VPD
----------------------------------------- My friend Aube Coote ( Retired Flying Instructor, and Airforce) build a standard KR2, Aeropower engine, he used a spring loaded trim, He has NO problems flying his KR2 hands off, ( good weather) He stayed at my place last night to look over my KR2 ( he will be the Test Pilot) and we got into the questions of fitting a trim system. He does not like the trim tab in the elevator ( personal choice) as he has had trim units fail in the past. His set up places pressure on the main controls, ( I sent a copy of this set up to M. Langford, last year), He is really happy with the way is works. I have not as yet build the TRIM system, so I can not supply photo's. But when I do I will place them on my web page.
