the dowel are preinstalled into the surfaces, and it's diameter is 3/4"... as for the wing attachment, EXCAP232 can you post a few pictures? my mind doesn't work well if i can see it... thanks. the engine i's planning to use is the Brison 3.2, i got a deal of Brison after calling them today, and the guy say if i call back within a week or two, the offer is still open, and it's for $449 for the Brison 3.2, can any other good engine beat that? if so please let me know, i really want to go for a DA 50 or a ZDZ engine, but the price is kinda high. and as for the scheme, i'm sticking w/ the fuse scheme, but after drawing on paper for hundred of time, i gave up not knowing w/ to do. please post some pictures, i would like to see your scheme and pictures of ANY wing attachment method.

PS. what kind of hardware do you use? does the control horn screw stick out on to the other side of the control surface? sorry for so many questions, this is my first.... first for digital servos, first gas, first giant scale... yeah, first.
