Re: SAAB Fighter

Rudders and sub-rudders done. I've tack-glued the rudders to the booms. I've decided NOT to bother with the landing gear - I want to first determine the this thing flies and is somewhat survivable. Total weight of all components: 9gm.

Re: SAAB Fighter

Just had to clamp everything together to get an idea of the whole mass of this puppy. For a 19 inch span model, it isn't "small" :o

I am a bit concerned about the survivability of the booms as designed...

Re: SAAB Fighter

Tip panels are practically done - just need to add the main LE and shape the TE. The center panel needs just the boom support ribs and a sub-spar. Really pleased that the tip panelsare exactly the same weight at the same construction stage @ 0.85 grams.

Added bonus... everything seems to fit :D !

Re: SAAB Fighter

Got some more building done. Second boom is completed and the wing center-section. I was quite pleased that the fit of the booms to the wing was very close - requiring little extra trimming. I will have to open up the area where the wing passes thru to compensate for the tissue thickness, but that's...

Re: SAAB Fighter

The majority of the fuselage and one boom is done plus the horz. stab. One thing about twin-boomed aircraft is the necessity of building essentially THREE fuselages :| . Weights are, at present, quite reasonable. I've a lot of modifying on the plan to do that would have been obvious had I been even ...

Re: SAAB Fighter

Slow going (as usual for me :| ), but cutting, test fitting, modifying and adjusting takes its toll. A number of the stringer notches as drawn in the rough plan were off quite a bit plus the two height errors on formers 3 and 4. The only notches that I pre-cut were on the nose former (the others wer...

Re: Indoor Flying with the O.F.F.C.

It's really great to see this bunch having a blast every month, Howard! I still haven't (totally) given up trying to coerce some of my "buddies" to have a go, but German stubbornness is nearly impossible to crack :roll: ...

Re: SAAB Fighter

Slow work due to too many other projects, but here are two pics. The "issues" with fitting are more to do with poor cutting - on these smaller models, a half millimeter makes a BIG difference! The one fuselage former (F3) was traced from the original hand drawing and I neglected to check t...

Re: SAAB Fighter

Started gluing up one of the booms and the fuselage to check parts fit and found a few areas that need adjustment - a couple of formers are a bit too short. Lot of work in this puppy, but otherwise is shaping up well. Pictures soon.
