Bi-Fire, scratch build

by RustyBucket | August 24, 2013 | (8) Posted in Projects

I have built about 6 Spitfires out of Coreflute and this time I made one with a little extra :-)

I was looking to build a Spitfire that could fly slow, so instead of tapering the wings, I continued the full width to the wing tips, once complete it looked that good I thought I should add another.

I pulled the top wing forward about 25mm (1") and offset the wings by a bit more than half the width of the wing. As this is what I could find from my google search on full size Bi-Plane design.

Anyway, it flys at about walking speed and makes me laugh each time I fly it.

Hope you like it. 

 

This is the single wing version and is now my favorite plane to fly. It flys perfect, slow or fast and on rails.

I would highly recommend building a square wing version of the FT Spitfire it is the best plane I have built so far and just a blast to fly.

As with all the FT Spitfire's I have built, I have made the fusulage slightly narrower and not bothered with the canopy. (Im into flying and building, not the cosmetics) and no rudder.

 

 Thanks for looking and thanks FT for keeping me motivated and constantly building plane after plane.

I like to see innovations, and am troubled by FT's open round wing tip but I am curious as to how you managed to get a spinner on the available prop adapters .Mine are not long enough and I can only catch 2 or 3 threads , not enough to be secure

Thanks, I don’t know about innovative, but I just love building things and tossing them in the air. The square wingtip with the same profile as at the fuselage seams to perform great. As for the spinner, I’m not sure what to tell you, mine is close, but probably has about 4 full threads in place, not great but I feel it’s enough for these planes.

Yes, I used the same wing profile from fuselage to wing tip.
I don’t know a lot about aerodynamics but I wanted more wing area in an effort to fly slower. The single wing version is great. I spent most of the weekend just buzzing around my local park at about 6 – 8 ft. off the ground, great fun easy to fly plane.

best for a slow flyer wing. Like the slow stick. I was going to build a slow flyer pusher with undercambered wing this week for my gf and kids. Almost like old fogey but bigger
