I have just finished building the GP Ryan Sta M. On it the tailwheel is connected to the rudder servo through a pushrod of its own running through the plane. I will take a picture of it and send it to you if yoy would like to see it. Also, since I am using a Thunder Tiger 91 four stroke to power my plane, I inverted the engine and purchased a OS 90 degree exhaust extension. Used in conjuction with the one that comes with the engine and a short piece of 3/8 tubing I have the exhaust coming out of the cowl at the bottom and have no holes in it for the exhaust system. I will also send you pictures of that if you wish them. I will try to post them tommorrow. There is an excellant article on the construction at this link. http://www.geocities.com/jbrundt2/ST-M.html Try it, even though it is the M version they are pretty much the same.
