Default 48" Minimoa

Hi Guys,
I started this in the wrong place, (it was in the science section).
Anyway, here is a 48" Minimoa, I scratch built from a 3 view I found on the Net.
It uses 3 servos, 2 aileron and 1 elevator.
I still have to hook up the elevator, it is proving to be difficult due to the ideal exit point for the push rod is just a little low and inside.
Enjoy...
First my funky hand drawn plans, I came out with multiplying everything by something like 4.085, pretty goofy I know.

I fiddled around drawing bulkheads in a teardrop shape until I was happy, then I just took the biggest one and drew smaller ones keeping the keel and main side stringers the same. (I got to get a cad program...)


Fuse and rudder.

I haven't built in about 8 years. The leading and trailing edge was cut from some huge TE stock I had on hand from the old days. WOW, it looks heavy...



After some sanding I dont feel so bad, it is looking rather light.

covered...still need to do the top of the fuse above the wing. Dope is still drying so it looks a little mottled.



This is why I built this thing, I love this look, just like a bird...

Still some more painting to go. Started playing with the printer, the markings are just tacked on for photo purposes. I have some old printer decal paper but I need to take it to some one who has a laser printer.

Those are my initials and birth date. Also note the flying Hog on the nose.





I also made the canopy hinged. I still need to figure out how to latch it.

I hope to fly it this weekend...I will put out an update.

the canopy is a test pull using a cherry tomatoe container.

The airfoil is a Clark Y that I printed from the old original Profili program I still had.

I still have to paint the under side of the wing and do a little more touch up.

Test flight last night. It was getting dark and I wasn't sure if I had the CG right. I will do more today and try to get better vids.

Looks like the balance is very close, but if you want to check it, compare it or find it for a new model please visit www.TailwindGliders.com and read and download "Sailplane Calc". It will always give you a safe location for a first test flight for a model design such as yours.

Any questions please don't hesitate to ask.
