Cpt Crash

I want to 3D the airplane and make it last as long as possible (Isint that kind of impossible?). Phoenix has another airplane -the Yak 60" which is the same airplane- just with a radial cowl and a round fuse. I and a collegue are 3Ding that airplane (its his plane. I have one too but its still in box) with a 120ax so we are finding out what the problem areas are on the Extra. Since he moved from the 16x8 to 18x6, he can hover at 40% throttle with no rudder correction needed which is quite spectacular. The vibrations have increased, however, he had difficulty keeping the cowl screws on even with the 16x8. That is the primary reason I was thinking fo the anti-vibe mount

I have reinforced what I can reach for now including firewall (I will fiberglass that also), LG block, all bulkheads and where I could reach. Pictures are attached. I used epoxy with filler everywhere and used CA only to tack. Its not pretty, I know, but I dont mind if it does the job. I am also going to open up the bottom of the fuse towards the tail- the last two open bays, put in ply from inside the tail and fiberglass the tail from inside to reinforce it, the re-cover it. Its a lot of work, I know, but I have seen it pay on other airplanes. All of this will add some weight hence the larger engine, larger 3" wheels (which will allow for the bigger prop) and a 18x6 or 17x4 prop. I am currently testing this setup on the yak. So I dont expect (and dont want) a disintegrated fuse. I am also planning wing tip SFGs so as to add more landing stability

If you look at it, what options do I have? The 95ax would be too weak for this airplane especially after what I have done to it and 1.08 is no longer available. In any case, the 120 fits in the same holes sat the 75 and 95. I have a 75ax and a fs91sII but nothing between those and the 120.

In any case, I dont like to fly fast so, unless I deadstick (dont even mention that word right now) I should be OK
