Default Shrike 10

Well, after 2 weeks (one to build and one to cover), here is my new lil shrike. It's the 10 sized version with a Magnum XL-15 and tuned pipe. I wanted to achieve a jet look to it so I moved the canopy forward and shortened the hatch. this also meant rotating the engine to run the pipe under the fuse and I made up a f/g belly to house the pipe and be strong enough to belly land on. Also modified a williams bros pilot to continue with the 'jet' look. All finished weight is 2lbs 8 ozs.

Thanks guys!! I'm pleased with how it turned out. Haven't flown it yet....just finished it last night. The weather out here is [sm=thumbdown.gif] so i'll proably put it aside until spring. It's building season. [8D] Next project is an ACM Whiplash....then I'll be back to some scale stuff.

That's georgeous! I can see where you snuck in some scale like skills to put an already sharp looking design over the top!

Wow, Absolutely the best looking shrike I have seen. That covering job is awesome! I nearly dipped mine in glue and painted it after beating my head against the wall trying to cover that thing. It is a real pain to cover after built. Nice work! If you are interested in selling it, put me on the first to contact list.

Thanks guys!! The Shrike was just begging to have more of a 'jet' look to it. [8D]

I'll be going with a Jett FIRE 50 on the Whiplash....figure I can't go wrong with that combo. I'll post some pics when it's finished..should be painting it over the TG holiday weekend.

Well gang, I finished painting my whiplash on the weekend. I'll be happy if I don't see another piece of masking tape for a few weeks!! The letters TGM are my dad's initials...the plane is a tribute to him, who was known to many as Superman, for his 1:1 scale flying superman model he designed and built and flew often, delighting fellow modellers and spectators alike.

here's a couple pics of my dad's superman...that's me holding the big guy. I still have it and hope to fly it again this year. It's always a head turner. Hand launch, and 'true' belly landing!

Too cool....[sm=thumbup.gif] What is Superman made out of ?

yup...the 'man of steel' is really just a man of foam, ply and balsa! The body is made from blue foam covered in money-kote and the wing/cape is a built-up structure from balsa and spruce.

Sean,

Your father would have been impressed with your Whiplash. I am unable to recall a more innovative model than his superman. You should write a magazine feature about it.

Hey love the color scheme! Looks like mine!

I like your idea of the underbelly. Awesome job!
Oh yeah you may wanna put a big long peice of clear covering on belly. That way it wont snagg your bird on the bottom on the edges like mine did.

I just retired Shrike .10 last weekend when my spar broke in air for second time. I am either going to build another Shrike .10 or put the engine in some small reno racer type plane. I havent decided yet. I loved my Shrike but didnt like belly landing it so much. Especially after I seen what it did to my bird on bottom time after time..

Thanks guys for the comps on superman and the shrike.

To make the belly was quite easy, what I did was build the fuse per the plan for the most part, and mounted the engine and pipe. Once I knew how much room i needed i removed the engine and pipe and cut a chunk of pink foam (you know, the dense insulating sort you can get at home depot) to fit on the fuse. then carved and sanded it to a pleasing exterior shape (still keeping it as a solid block). then i used a number of layers of fiberglass cloth and covered the foam 'plug'. keeping it on the foam, i used filler and primer and sanded it etc, until i got a nice smooth surface. it's much easier to work on it while its still solid. then i cut and removed as much of the foam as possible from the inside. this is actually called a 'lost wax' method of molding as you destroy and lose the mold. great though for 'one off' parts. once the plug as removed i trimmed the endges and opened up the front and back etc. i test fitted it on the fuse. i used a pair of 1/4x1/4 'rails' down the side of the fuse about 1/16" in from the edges to give it a nice attachement point. before finally attaching the f/g belly, i painted some thinned epoxy on the wood under the belly, and painted it navy blue with K&B epoxy, to fuel proof it. then i used a slow cure epoxy glue to attach the belly. a little filler along the seam and voila. i'll attach a picture of it before it was painted and covered. the model was then covered with monokote and some of the more complex curves on the belly was painted with epoxy paint. I did add a strip of clear packing tape along the belly to protect it on landings. All and all it turned out pretty good. good luck with yours and feel free to ask any questions....better yet, post em online and we'll keep an eye on your progress. [8D]

Thx Smchale for the details.

then i used a number of layers
I wonder how many layers of fiberglass cloth are required to get that strength.
Did you install any former inside the belly ? It might not survive many hard landings without cracking in the long term, don't you think so ?

The underbelly looks so smooth and has a perfect shape. By looking at the pics I would of never thought it was hand made. I just sat here and read how you made the under belly. It all makes sense on how to make one. But I still doubt I can make one, I always been intiminated of trying to make glass parts. I'll just look for now..haha

Thanks for the comps guys. I think my 'long windedness' makes it sound more complicated than it really is. The final weight of the model is 2lbs 8 oz...so i'm 8 oz. over the published weight. I don't think it will make a significant difference, and for me the 'looks' make up for it. I can't say exactly how many layers are on it as i overlapped a lot of it as i was laying it up. I'd guess everywhere has at least 1 layer of 6 oz, 2-3 of 2 oz, and 1-2 of .5 oz. Don't quote me on that as it's just a mish-mash of bits in my cloth box. There are no formers on the inside, yet it is very very solid. I have the 1/4 sq. rails along each side that gave me ample gluing surface. Also, my molding the front and back, then opening it up, but not ALL the way up, it's left a lip at each end that aids greatly in the added strength. To be honest, if I land hard enough to crack this, then i'm certain that i will be doing worst damage to other areas. [] And hey, if it doesn't work I haven't lost anything with a $35 kit and a few materials laying around the shop....nothing ventured, nothing gained! When the weather improves i'll post flight reports....proably in the spring...
