Hey, just thought I'd check back in with a quick update. I ran into a problem ... may be a showstopper, or not ... we'll see. My elevator hinge design I thought was pretty cool, but it's not as friction free as I would have hoped. The servo is plenty strong to move the surface, but the thin wire pushrod that comes with the tiny tutor ends up being too flexible (for the friction in the hinge) and bows out instead of pushing the elevator back up. I probably should have seen this coming, but didn't ... oh well. So the obvious solution is mount the servo in the way back with the shortest pushrod possible ... but I already have a CG issue with the 3d printed surfaces being heavier than foamboard .... so .... I'll have to take a step back and think about what I wan to do next. Maybe some redesign, maybe a stiffer wire pushrod, move the servos to the tail and eat whatever CG penalty I have to eat? Anyway, oh well, I've learned a lot so far, but definitely need some rework before I continue. And still waiting for a calm enough, warm enough weekend day to test fly the all foam stock tiny tutor. One of the downsides of northern mn and working full time is you can go really long stretches through the winter months with no good flying days. It's already dark when I get home from work, and the weekends sail by. Not complaining, it's beautiful up here, just wish I could do everything all at once!
