Say, what do you call it anyway, a Boomer Stick?

If it comes back to you, you can call it at Boomerang

In fact, the rib shape is not too dissimilar from a traditional hunting boomerang. (just a bit of useless trivia for ya)

Final word after flying several battery packs through it! First I would extend the rib to at least 6 inches instead of the 4-1/2" I used as the higher wing loading makes the plane fly too fast for the little cul de sac to be comfortable. I didn't have a problem but things happen to quickly to be comfortable! With a little less wing loading it would be great! I would also use hardwood small dowel for the leading edge to give the wing more strength because in a loop you can see quite a bit of flexing or go to a center spar. Other than that it's a great little flyer.

Top side only covered on the wing. Tail feathers covered both sides. WS=30" Fuse length 17" but this can be longer if you widen the wing.

thanks boomer.....I printed the rib pattern at 6" ....hope you don't mind me copying this one....I have been looking for a kit to build but this is much more interesting to go for.......what do you think of an IPS A drive....I have one on hand....too much power? I have an S1 drive also but it is the dual and may add too much weight .....Thanks again....Tom

A drive should work fine but I would add a wing spar or use hardwood for the leading and trailing edge. Due to the extra weight & power. You will also have to extend the landing gear to clear the prop.

Boomer,

Great looking aircraft. What type of covering material did you use, also, is there a main spar for the wing, or just LE and TE

Covering is SoLite no main spar but use laminated trailing and LE or hardwood.

Mine is coming along well......need to cover and install the electrics.......going to the six inch wing chord and a length of 20 inches where should I be looking for this to balance? I am thinking somewhere around one third of the chord...

I would go just a little less than that for your first flight as I like to go a little nose heavy tell I see how it handles.
