TA 152

Ken Armish built this nice TA 152 from some plans I sketched up. A very nice first flight followed by jammed leadouts and a spectacular crash. Other than being a bit tail heavy on the first flight, it flew really straight and nice. Unfortunately the leadout guide jammed. It used the eyelets in a slot method. The eyelets slipped out and the leadout wires jammed in the slot. Made some very spectacular, tight figure eights.

61 in. span 650 squares. 43 oz. LA 40 Worked well with an 11/4 Zinger and the stock muffler. 10% nitro, 28%oil. The fuse outline is scale. The wing is scale, but a much larger percentage. Tail is pretty much scale, 100 sq. in. with the elevator about half an inch wider than scale. Still looks pretty small, but worked just fine.

We'll probably resurrect this one. The fuse was destroyed, but the complete tail assembly and most of the wings are fixable.

Nice.

Kind of reminds me of the old Ambroid Super Whipsaw. Plan form of the wing, anyway...

That ate its Wheaties ( no 'roid rage then).

You also have a single digit wing loading.

9.5 oz/ft and a high AR and an aft CG means:

Whoa...It will turn...

Currell,
I am presently waiting on some decent weather to try out my Giant Stuntmaster with its new engine..... Johnson CS! Will use a 4 pitch prop. Flew nicely with a Red Head 35, but have never flown the Johnson.

This looks like a very capable stunt ship. Are there any plans for it?

is that the 500 wing with wing tips?

These are both a takeoff on the Giles I've been flying. Very capable stunters with a bit sleeker appearance. The sorta Spit in the background used an overweight set of test panels I didn't want to throw away. The TA152 uses a different wing panel- slightly smaller chord, more taper, but still an 18% section. The wings all use the self-jigging internal I-beam spar. I can imagine(only imagine) building a wing like this up, maybe by lost-foam or with a jig. It might save an ounce of weight if you got some really quality 4 lb. wood. The wings are coming in around 10 oz. ready to start covering and painting.

These are all in the sketch plan stage. Can't really see detailing the plans. The fuse outline seems to be pretty non-critical. I just blew up a magazine drawing to the right length and tweaked it a bit to make it look more "Focke Wulf". The fuselage uses some very simple composite techniques to make it very light and stiff- 3/4 in. contest balsa front end, fiberglass doublers(no ply!!) and a foam core to the rear. Ken didn't wait for me to slice him a core and built up the rear of the TA 152 fuse. That's partly why it broke up so bad. The built up portion just shattered and tore the plane apart. The Spit has crashed twice out of loops and just bent the landing gear a little.

'just curious, but what is the aspect ratio on the TA 152?

61*61/650 or 5.72
