I like the idea of adding a second servo for flaperons. Could open other options for mixing with elevator for some fun.
I actually dont mind so much about it heading up with speed, its such a laugh.
Has anybody tried adding a lower KFm4 step?
All my FB's from my 16.5"er to my 39" version have been built with a KFm-4 wing and all fly brilliantly. They all track really well and laugh in the face of windy conditions. The small versions is a wee bit twitchy, the bigun is more of a floater, which I reckon would slope soar with it's lighter wing loading but the best compromise is the original version. I also extended the nose on all of mine.
