TOPIC: F22 Raptor

Just a thought: if Howard is building an F-22, how about one of us builing a Su-57?





I've been searching for a 'proper' 3-view to build from .... no luck yet, but I'm sure it will make for an interesting model. The build should not be that dissimilar to the F-22.

Here is my ‘work in progress’ plan of the F22 Raptor, a couple of formers are still to be added and the fuselage needs some revisions. Some of it is speculative so it may have to be amended as I try to build it. Basically there is a 3mm balsa vertical spine nose to tail with skeletal formers mostly made from 1.5mm x 4.5mm balsa and sheathed in 1.5mm balsa sheet, it may well have to built in 4 sections joining them all up on the 3mm balsa wing.
You will notice that the Raptor’s nose is angled downwards somewhat as are flanking body surfaces ahead of the wing, 4 degrees and 3 degrees respectively. Because I think that these will affect the flight of the model, I have given the tailplanes 3.5 degrees positive incidence while the wing is set at 0 degrees, I hope it is enough. This is all guess work of course and I may have to fit elevators after the test glides.

Ha ha, love it. A few more too to add now though.

Here is a loose assembly of the some of the built up formers for the fuselage undersides, it has been slow progress so far and just putting these bits together show me that some mods need to be done already,. Oh well, I'll keep plugging away.

Today's tricky little assembly, it will be cut into several pieces for each side of spine and above and below the horizontal split line. This former takes the ends of the lower nose sheeting, the base of the intakes and the lower outer sheeting for the main rear body. A bit of progress.
