Jack's treatise on installing pinned hinges failed to mention that a greater gap will exist between the control surface and it's stabilizer or wing, but for the type of flying we do, it doesn't matter......in fact I'm starting to prefer that 3/32" gap, as it allows 90 degree throws either way. I never fly WOT (outside of vertical) so flutter has never been a problem.

I've been flying this T _ _ _ T hard, for nine months and I've had to replace the rudder CA hinges once and I check the hinges before and after every flying session. (This after landing once with only the top hinge still attached to the rudder.)

Dutch.......whatever you do, please balance that plane by moving things around, not by adding weight! I've flown many a T _ _ _ T with the S.T. .51 and I was content (at the time) to do so, but after taking the OS .61 that was lying around the shop and installing it........I could never, ever think of going back. My experience with the S.T.'s are that they are a touchy lot.......if you find yourself adjusting the needle often, look to a possible muffler/baffle restriction that may be over pressurizing the tank. Run them rich and be careful of overheating if using a 12.25x3.75 or larger, especially if the air temp is above 70 degrees. Also do yourself a favor and use the longest possible servo arm you have for the throttle. I use an inch and a quarter arm with fantastic results. Exponetial is putting hobbles on, do yourself a favor and enjoy the direct connectedness that comes from 1 to 1.

Peace,
