I’ll tell him that you liked it!

Here it is, prior to combat. 🙂 We chose 140%, because that’s the largest that we could scale it up without splitting the wing into more sheets. The motor we had on it was underpowered, but it flew well regardless. I have the scaled plans for it, before we made it into a bi-plane, if you want. Converting it was pretty easy. We build a second identical wing, then re-mounted one on the bottom, about an inch back, and one at the top, two inches forward from the bottom wing. IIRC, we used the original COG and it worked pretty well. To mount the bottom wing, we used half of the new wing (before we glued it together), and placed it next to the fuselage and traced the shape on the side and cut that out. To mount the top wing, we stacked a few rolls of tape on either side to elevate the wing to the same height on either side, eyeballed the alignment, and started stabbing BBQ skewers through. It turned out pretty well considering the rough “engineering”. 🙂 He will be thrilled to hear that you liked it though!

Update: The big washer on the nose reminded me that we needed to add nose weight. So on our next one, just using a bigger motor will probably balance it nicely.

Hmm... This biplane gives me an idea. But I shall have to smallen* it, as I often do and make some other modifications, and add a bit here and move a bit there... yes, I can definitely see it in my head. Bwahahahaha! Things are brewing in Dragonfly lab of Fishbones Air. Stay tuned.

*Smallen. To shrink, reduce. My wife invented the word when she was young. She still uses it, and I still tease her.

Oh yeah! That’s the one! I’m definitely going to build one. I can scale the plans up fine and with the info provided here, I’m pretty set. Thanks!
