..dose this happen...from centre to ful left or right eleron....load netral centre stick......centering force increases as stick is pushed left or right.......near to far left or right force deminishes and close to end of the stick travel force diminishes and then starts to reverses and snaps to full travel?
That pretty much describes it. When I built it I tried to allow as much travel as possible but I may have over done it. When you move the stick the flapperons move in opposite directions, but most of the movement is in the up direction. The opposite flapperon is moving down but much less. Probably, as you say, to reduce adverse yaw. I did notice that at the extreme end of the travel, the flapperon going down will reverse direction and go back up slightly. I suspect that is when the stick gets weird. The weather has turned particularly nasty here of late so I won't have a chance to go out flying again before I head south with it next week. I'm going to Wallaby Ranch and there are 3 of them there so I'll have plenty of opportunity to figure out what is going on.

my take on the diferent travel in eleron...ie moor on the up side than the down is to reduce adverse yaw.
that why we dont have an even amount of travel.
from what you are saying i suspect your bell crank is traveling futher than it should be allowed to.....and when it goes over centre the force is reversed and is snaping the stick to the side.
dose this happen...from centre to ful left or right eleron....load netral centre stick......centering force increases as stick is pushed left or right.......near to far left or right force deminishes and close to end of the stick travel force diminishes and then starts to reverses and snaps to full travel?
if yes assemble the aircraft......fix one bungy cord up and one down on one flaperon to crate a nutraling force when it is deflected.
does the stick snap to full left and right?
if yes.
use small g clamps to make the bell crank stop before it goes over centre.
ill wait to hear from you.

Rick,
Great news. Keep the tips flying , sailplanes tend to tip stall and spin , lead the turns with rudder.
Regards,

It took almost 4 years but I took the first flight yesterday. Everything went well and I was surprised to even have a little lift to work on a cold winter day. First impressions: The sink rate and thermalling is awesome. The controls will take a little getting used to. The roll control feels a little strange. I have no experience in sailplanes and only about 400 in small planes. The roll pressures are heavier than I expected and while the stick is mostly neutral in the center as you start getting to the extremes the stick wants to "fall" the rest of the way to the limit. Maybe a quirk of the way the way the triangular control block works as it goes over center or maybe I don't have something adjusted quite right? Maybe someone here who has flown one can comment. But over all I can tell I'm going to have a good time with this. The day after Christmas I'm heading to Florida, warm weather, and thermals to get wired into this thing.. I've uploaded a few new pictures of my first flights.
