You do not need an airfoiled tail. The full scale is flat as a pancake. When the elevators deflects, it's the curved surface creating lift moving the tail moment. Most of the foam you see will be gone. Sticks will be inlaid and all the rest removed. All edges will be glassed and then covered with what ever. The foam core is for shape only. Hang in there. You'll see.

I want to stress this aircraft is scale. Look at the picture.

I have a good friend that had an S2a. I have about 3 hours in the front seat. The flat tail has more authority than you could ever imagine. You could pull enough G's to pass out at a moments notice. Snaps are incredible. Flat tail. Sorry for beating this.

MattyMatt,
Not sure if I answered you on the specs. go to www.pittspython.com and divide by 2. 12s specs. Now I do remember replying.

Ok. Got this feeling people are freaking out over the foam.

I guess Burt Rutan is an A$%.

Here's where we're going with this.

Photo's of glass over foam. These are an experiment I did years ago. 3m77 spray. Glass cloth from Lowe's this time, and Polyurethane Glue.

Hint...Hint. Try this at home. You can make all kinds of cool parts.

If you can't read my writing let me know and I'll type it out.

Got the wing done!!! Ha......... Love the smell of fresh cut foam. Bye..

Karl,
Your a machine.
You have done your homework also!

Any carbon strategy?

Ronster

Great project.. There is someone out there that has an ARF 50% M12 so it will be interesting to see what a scrath built one can do. I think its such a fatastic plane. I love mine !

As in carbon fibe graphlite rod????? No. Keeping this as simple as possibe. I want to put the chinese out of business.

Get some American pride back.

I looked at Comp Arfs. I think it was 3800.00. Holly crap. I just love to build. Probably won't have more than 3-400 in this.

you are gonna build this faster than i am gonna build my pitts 12 arf! The scale look is it, I dont like when they put the wings on top of each other and reduce the height of the top one. Worse than any atrocity.

dang Great build ........

hi karl after being picked up off the floor from my finance minister (WIFE) she asked why i fainted ?
dam this guys crazy look at his work ,,,, she said wow & you no what we agree on some thing for once lmao.
keep up the great work im here till the end.

Excellent!! This is all unbelievably easy. Trust me it doesn't take a rocket scientist. Been gatherin this stuff for years. This is the easiest way that I have found. There are a lot of different ways to skin a cat. This is just mine.

Got a poster of Albert Einstein in my shop riding a bicycle grinning ear to ear. It's all about havin fun guys.

I take my statement back about the stabs, I didn't know they were flat. I have no problem with the foam parts, I know once glassed they are super strong, thats how surfboards are made.

She should fly fine. I did notice going thru pictures last night that the whole horizontal is shifted forward leaving more room for the rudder deflection. I may cheat it just a pinch more. Just a pinch. 45 degree deflection is the goal.

I never knew that. Kind of like a cap 231. Check out this pic.

Have to go to work. Sh&*
