4*120 Biplane Kit Bash
Has anyone ever thought about buying a extra wing kit for the 4*120 and bashing the kit into a bipe?
I built a 4*120 a couple years ago and ended up selling it. I regret it. Wish I'd kept it. They fly so nice.
I was planning to build the kit again, so I bought a wing kit with the intention of scratching the fuse and formers from my old plans. I just LOVE a good kit bash and got to thinking about using that spare wing kit to turn this into a good size bipe.
I think I'd want to widen the fuse by a couple inches and maybe stretch it out to about 70" in length. In stock form, the kit is only about 4" wide inside. It's a royal PITA to get your hands inside there. I'm thinking it wouldn't be that hard to widen the fuse to 6" all the way to the back of the wing saddle. All I'd have to do is widen my fuse formers by 2". No big deal if I'm planning to scratch build the fuse anyway.
The 81" wing is really hard to fit in my Nissan pickup, so I was thinking about clipping the wings down to about 72". It would still have a ton of wing area. If you knock each wing down to 72", you'd end up with about 1071sq.in. Now add the top wing and you'll have 2142 sq.in.
I think I'd probably go up to a 50cc engine at that point. This plane will probably end up in the 16-18 pound range. 50cc sounds about right for aggressive sport power at my altitude.
Any thoughts or comments?
