I personally never found a thing wrong with Homers original design on my MKII Twinstar. Why try to reinvent a good, simple design that works? Just my experience.

I've never had much luck with search engines on the forums. I need to get to work on this MKII.. and I've heard lots about offset fins, trim tabs, and slow flutter issues. Uh.. ANY indication to flutter, IMHO needs revision. I'm considering a new tail group, with built in trim tabs, (using a servo drive for each), and aerodynamic and physical balance as well. I was never fond of the over-simplified outlines.. because I'm sure they were intended as simple. But there isn't much rocket science to building better ones, with balance.. that are much less prone to flag-waving and/or departure from the aircraft. And I know there are many opinions.. but curious about what others might have to say.. or like the photo link to a balanced rudder (which looked rather out of place.. ie long tube forward, with steep pipe to balance it).. but if it worked, that is what is hugely important. One thought on this possible revision, is a resettable leading edge offs! > et for either the fin or the horizontal stab.. or even using them as the primary "trim" function. (aka J-3 Cub trim).

From: "Richard Pike" "Richard Pike did some work along those lines. If he doesn't see this, get ahold of him on Facebook. Bill Sullivan" I think he is referring to my admitedly curious rudder counterbalance: " or like the photo link to a balanced rudder (which looked rather out of place.. ie long tube forward, with steep pipe to balance it).. but if it worked, that is what is hugely important. " http://oh2fly.net/oldpoops/pg6.htm As long as you keep your feet on the rudder pedals, no flutter. Take your feet off the pedals, you need some serious tension springs. My springs were as strong as I could deal with, in terms of hooking them up, and they were insufficient, so I went with a counterbalance. -------- Richard Pike Kolb MKIII N420P (420ldPoops) Kolb Firefly Part 103 legal Kingsport, TN 3TN0 Forgiving is tough, being forgiven is wonderful, and God's grace really is amazing.
