It's been a long time since I've posted anything here but I love my latest build so much I decided to share.

I've always wanted a Quickie. I wanted an RC version scratch built but never got around to building one. I built plenty of tandem wings both RC and free-flight but never got around to building the Quickie.

Last week a friend of mine wondered how difficult it would be to build a Peanut scale Quickie. I googled around and found several old builds. Then we stumbled upon a no-cal Quickie. I decided to quickly build a simple profile Quickie to figure out CG and trim.

Found a simple profile plan online. Got some 1mm balsa left over. Two days of cutting and gluing and I got myself a nice little flier.

For this build I'm using foamie building techniques - tracing paper templates onto the build material.

The plane is made of 1mm balsa

The wings are wet-formed to add camber.

The "stick" is 1.5mm balsa (roughly 1/16). I think you can build the whole thing with just 1/16 selecting light balsa for the wings and fuse and heavier balsa for the stick. I did add a strip of 1mm balsa directly below the motor stick as reinforcement.

I gave up trying to figure out how to make the wings removable. The span is just 10" so I can just build a small box to transport the plane whole.

After a few test glides I had to add some reinforcements. The canard especially had to be reinforced because it is also the landing gear and gets abused a lot when landing.

The dihedral is slightly more than what's in the plan and the anhedral for the canard is a bit less.

The CG and incidence in the plan is very-very neutral. If you launch it wrong it will nose-tuck and dive. I added up-elevator by twisting washout into the wings and moved the CG forward roughly 5mm. If I were to do this again I'd build in extra 3 to 4 mm of incidence.

I've always wanted a Quickie...


I once asked my wife for a quickie and she said "as opposed to what?"
