elecfly,
give me time and i will get you the pics posted here. got to tracel this week and no time to get the pic and then post.
anyway, i built the first fuse according to the plans and used the push rods as suggested. they were fine for the 25-35 engine range but i a little sluggish when you put it in a dive and really picked up speed the elevator became sluggish. SO, after a high speed landing i had to rebuild the fuse and tried 1 inch longer and a half inch wider, i used the originalformers that remained and enlarged them slightly to give me a half inch overall (formers+new fuse sides=1/2 inch wider than plans) and let the extra in longer come out the back end of the fuse. this allowed for the center line to remain the same and the wing to be mounted exactly like the plans.
low and behold i had plenty of room to get inside the fuse this time. i forgot to mention that it is extremely tight "by the plans" and hairy close when you mount the wing with the aileron servo having to fit between the mounting lugs and the rear part of the saddle. it works but barely. on my second fuse and if i may suggest, i modified the wing for individual ailieron servos. i know from your post above the wing is already done but i modified mine after many flights and it really wast that hard. the trick part is getting the original torque rods out of the trailling edge in the center. luckily i got mine all the way out, drilled holes thru the ribs to run the extension thru the servo bay for the original wing servo and connected them both with a Y harness. the reason i mention this is if you have already completed the fuse and need some extra room this might be an option to think about before covering. it also provides for super response at all speeds. i like your idea of using laser rods. they will work much better than the pushrods the kit comes with.
as soon as i get a chance i will post some detailed pics for you on my mods. last year i clocked at 108 with a 40. you should be in that range with your 46.
let me know where you are in your build, and if you have any other questions.
