So, I know that I said the Delanne Twin tandem wing was my next design and build, but as I was laying out the plans I saw the fuselage and wings I'd done before the redesign of the J-3 Cubbish. On that first fuselage the wing cord is almost a 1/3 of the total length of the plane, and that didn't look right for a J-3. However, it vaguely reminded me of a Lazy Bee. So, I thought, "Why not finish it and see if it'll fly." (Yes, I'm certain that I talk to myself in quotes like that.)
Looking at it though, I thought the rudder and elevator I'd used on the J-3 Cubbish was too small to control those wide wings, so I drew larger ones that are a little bit Lazy Bee-ish. I cut those out, put in electronics from planes I was salvaging and had it ready to go in time for a Fall wind storm that went on and off for three days.
Took it out to the field today and fully expected it to crash. Flies great! Slower than the J-3 Cubbish on lower power. It can fly 1/4 throttle low and slow, and it can get a little zippy when you give it the power. Had about a 7mph wind over the field, so I could almost hang it over my head in to the wind. I suppose I should put some wheels on it. If I can find some 2" toy car wheels, that would be perfect, and think I'll place them like the wheels are placed on the Lazy Bee.
This is a one sheet of foam board design. It uses a Flite Test Power Pack A, and I was flying it on 2S 900maH batteries. Like the Mighty Mini Scout, I glued the servos to the insides of the fuselage about where the wing's creased. I still had to put 1/2 oz. of weight in the front to balance it (2 of those stick-on tire balancing weights.).
Comparison of the J-3 Cubbish and Lazy-J.
With wheels. Oddly, I couldn't find cheap plastic cars with the right sized wheels, so I used the 2" foam ones I was saving for another build.
Edit: Redesigned the Mk.II fuselage to reduce twist while building.
