Cutting some Litehawks. Still not real good cutting foam, but with the single template method, can mage good wings. Not exactly a Lite hawk, but close.

3/3/2017 Update from Chris, ready for belcrank and control system. Chris is building a smaller version of his T38. Just getting started. Cool jig!
From Howard:
Here's my second building contest entry fresh from the laser cutter. The model is of the "Stinger" Formula one racing plane from the early 70s. The model is designed to conform to Dallas Sport Goodyear racing rules. 1/8th scale, 29 inch span powered by a Magnum XLS .15 as per the Sport Goodyear regulations. You will notice even the engine is in a dozen pieces! Design and plans are from Big How's own fertile mind. Its no secret that Howard loves autogiros. He has entertained club members for years with sweet flying giro's that meet and untimely end in horrific (and funny) landing accidents. They do fly really well, he is a true master builder and he is not afraid of finding the edge of the performance envelop.
Never one to quit looks like this is number 4 for Howard-the-giro Randy Likes working with coraplast and is a big fan of the old television show "Voyage to the bottom of the Sea". This is his 1/2a entry to be powered by a rather worn out Cox product engine. 2/25/2018 Randy is making progress, all the parts are painted and assembled.
4/22 update. Although Mike doesn't like monokote, the transparent red sure makes this look good. Mike is staring another one. This one is Beech Staggerwing biplane an I BEAM no less. This is his third entry. Update 2/25 Mihjas it all framed up, look at the sliced ribs.
I am going to build a few foamies this winter for speed limit and general screwing around. They will be about 52 inches in span with a 12 inch root and 8 inch tip chord. The airfoil is a NACA0015-92, The -92 moves the high point forward from 30 to 20% and blunts the leading edge. It will have a tapered spars top and bottom. The spar notch it too large on the pictures. I will cut the foam on my home brew weight fall foam cutter. At least one will have a hard tank and all will allow mufflers when practice flying. It will be a lot like the Yankee nipper except a little leading edge sweep helps in a crash and I think the boom needs to be a little longer. Power will be one of my OS SFR 25's wiht metal motor mounts. templates all ready for final polishing and wing cutting Spar stock, some old growth douglass fir. cut offs from another project. beautiful grain Not much progress, the templates did not product good cores. I need to rethink the lead in angles when using a feather cut system. While the feather cus system is really cool, many things have to be perfect to wok out. The scrap however has been turned into some more 1/2A airplanes. The cuts were made with a single template and a fixed pivot. I get very good results wiht that method. Mike is building an Electric Rat racer. Don't know much about it except the design sketches are below and it will be powered by and e flight 25 motor. More updates the wing is shaped and the rest is cut out. Trial fitting equipment 5 pounds in a 1 pound bag
Here's one of Mike's projects. A Super Geo lost foam wing that is going into an original design stunted. He will be also making an electric rat racer and a semi_scale stunt
Staggerwing Beechcraft. Wayne's solution is complete. Looks great! 3/2/2018 Wayne's Super Solution in paint and ready for final assembly! Wayne's entry looks to be a profile super solution. We can see it looks like the 40 inch model designed by Allen Brickhaus. We can see a 3 line bell crank and 40 engine. We will be interested in seeing his progress. The details on my entry as follows: This model, Laird Super Solution, is a 40 inch profile model built from Flying Models plans. I received them the week they went belly up. It will be powered by an old model O.S. .40 S which is a full bearing engine equipped with and OS carb so I will have throttle control. I do plan to enter it into the club contest next year providing that I can fly without falling down. I am building it with as close to scale as I can with the club contest in mind. There is a lot of balsa dust in my shop and I love it. Pictures to follow from my I pad. It all framed up and ready for covering. The woodwork looks awesome and wayne does a nice job with paint. |
