Steve,
The limbo dancer has as much throw on high as it has on low. The only difference is that I use positive expo on high and neg expo on low. Thats because even on low for taking of and landings, I want to know I have plenty of throuw in case I need. Besides, I like to go from an usual flight to a 3D flight (spins and such ) without having to flip the switches. Then I flip them up for torque roll and hovering only. Just a way I feel confortable with.
I was checking today and It probably has 60 or 70 degrees to each side from center. This is probably too much as it is probably acting as airbrake. Ill bring it down to 50 degrees or so. Ill probably have to move the cg a little aft. in fact, It has some nose weight to balance it. And steve, ill probably follow you advice and install some wires to keep the fin from flexing as well as keeping it from breaking.
regarding the slop in linkages, thats I am sure is not an issue as I am using pull pull for rud and ele and they are pretty tight.

I can hover my sig ultimate funfly for a good 30 seconds as well as my bearcat funfly and the rudder definitelly has plenty of authority as it will respond to any rudder input nearly instantly.

I use some POSITIVE (around 20%) expo on ele and rud on high rates and about 40%neg on low. Same throws on high or low rates.

Thanks again
