Evening Gents!

I thought I'd start a new thread for a 77% UFO which I'd like to build for a piped SuperTigre X25.

It would have trike Robart 600 mechanicals and 7 servos (3 in wing and 4 in fuse). I started with Rainedave's 66% plan (version 3 of this build thread), blew it up some and have been making some changes. Unfortunately I don't have access to David's DXF or DWG files so I've been working on a vectorized layered PDF file. Unless I can obtain the files from David, I might have to scratch build from these plans although Ideally I'd like to have it laser cut.

There are a couple of details which I haven't been able to resolve. If there are any CAD guru's who would like to lend a hand, we could get some kits laser cut and expedite the build process. I'd be happy to repay any assistance with a short kit from the cutter if that is of interest.

I'll post the state of the plans I've been working on for comments. For reference, the scaled down BHE plans are also posted. Note that there is a slight discrepancy between the BHE UFO 25 and the CAD UFO 25 with the latter being just a tad larger. The goal in scaling the CAD plan was to obtain a wing with a specific area for a loading in the 18 oz/sq ft.

Note also that the fuse top view does not match the former width as these were widened to obtain the desired space in the fuse. All formers were scaled in equal fashion width wise but F3 need not necessarily be that wide. In fact, F3 could be substituted for 1/4" square stock bracing and spread to the fuses natural airfoil as it tapers to the 5/16" tail (1/16" center sheet missing from tail junction on plans).

A PDF of the plans can be posted for anyone interested.

David.
