At 90kts and full trim I need to pull the stick with 0,5kg. Actually I have no spring installed. I thought about if the Lancair = springtrim would help, but I'm not sure if 2 systems would be a good = idea? A second solution would be to extend the surface of the trimtab. But = left and right elevator would be not symmetric anymore. Would the bigger elevator on one side change the flight characteristics? I would need a = 5/8" extension on full length of the trimtab... Thank you for your comments. Christian www.lancair.at
