I am currently working out the kinks of the Heinkel P-1077. Hand launch looks good but catapults act more spasmodic.

I am getting this one done in plain balsa . I will take a picture soon no matter what.

Interesting project. Kinda similar, but not like the V-1 and Okha. Similar idea though. Should be a very fast flyer.

I now have pictures ready to submit. I would like to add these without going thru my friend Curtis. Can the administrator give me help doing the set-up now?

FLYACE1946... sounds like you have quite a treasure there in that recognition manual.

Caley... too bad about the cards... those would be special also.

Well...I almost ruined the Banshee...got carried away with the paint. Warped the wingtip tanks and the horizontal stab strakes. They will be made integral with the wing on the next one. Too difficult to maintain alignment gluing them on later.

Well here's the Banshee, she has been trimmed since the paint and required additional ballast plus straightening of the right wingtip tank. As Pete pointed out with the F-89's tiptanks, they are quite sensitive in setting up trim and flight.

Here's pics of the F2H-1 painted up...Navy Blue from a rattlecan and the panel lines are white gel pen.

Regards,

Tom

Got it! But not yet put together and probably won't paint it. Cougar already flys.

Tom, That's really quite a wonderful model. You're sure artistic. I need to get those pens so I can start trying to do panel lines. The lines sure make the model more realistic.

Hi Tom: Great model and a pretty good shot of a future modeller. Is that the one designed by Bill Hannan and printed in SIG Modeller?

Thanks to all for the nice comments...

Caley... just a couple of sizes of Sharpie permanent markers "fine" and "medium" and a local Arts and Crafts Store (Michael's) for the white gel pen, in the scrap booking section, will get you started and then take a cereal box or FedEx box and cut a couple of strips of varying lengths and widths and your set. I even took a french curve to one piece to get the curved panel lines on one model. The flexibility of the cardboard works on the curved surfaces. I also use the cardboard to clear the felt tips from time to time as they can get gummed up with the ink some what dissolving the paint.

FAAMAN... Brubaker's Panther would be great...I'll have to build Pit's plan and paint it up.... won't get the flight times of Pit... because of the paint but he's already done the hard work to get them in the air. I'll check out the F102 because it and she and her younger sister, the F106 are favorites of mine.

olddog... Aiden is my youngest grandson 3 years old, "Fetchermite" loves flying the planes. We do that regularly in the mornings when the wind is calmer here. Usually get a delta breeze up the delta from San Francisco most every evening so don't usually fly in the evenings. Didn't know of the Hannan plan... made mine from a 3 view and photoshop. I usually take the 3 view into photoshop and scale it to the size I want and then duplicate it taking one half of all flying surfaces and reversing them and adding them to the opposite side to get exactly the same size wings. I also enlarged the horizontal stab and vertial stab and rudder approximately 20% to add more stability. Really following Pit's lead here. I've really enjoyed these models and get a great kick out of them. But I do need to get a tighter circle glide trimmed into them. Had to chance the LearFan quite a ways to retrieve it when the Fetchermites weren't along. My site is a local park and I use most of it up flying the 12 to 15 seconds I usually get from a cat launch. Great fun...jump in. I'll post my plans of the Banshee when she gets a few cat launches under her belt.

Tom

My handley Page HP.115's main wing segment has been finished shaping, detail pics should show the leading edge shape as well as possible.

Keep flying!!

I just looked in Wikipedia on the HP115. Very interesting aircraft, originally towed to altitude and glided down, then fitted with one engine. There was a reference toward the bottom of the page that said that Boulton Paul P.111 was a comparable aircraft. I can see that it might also be a good subject for a CLG profile model.

Caley, check out this link to Jetex.org, http://www.jetex.org/scripts/yabb2/nph-YaBB.pl?num=1260554113, should answer your question, with a few tweaks of course.

Neil, Ah!, Rapier powered. Roger always does such nice graphic work. My guess was good that the Boulton Paul would be a good flyer. Got too much other builds going on. I just mentioned it in case someone wished to do another CLG.

Caley,

The HP.115 was never flown as a glider. It had the jet engine fitted from day one and used it on all it's flights. The HP.115 was built to test low speed handling of the highly swept delta wing as part of the development work for Concord. The proposal was originally for a glider but it was changed to jet powered before construction of the HP.115 was started.

The BAC 221 was developed to test the high speed regime of a Concord type wing.. The HP 221 would make a really nice cat jet Wink

Nice Banshee Tom, now all we need is an FH-1 Phantom !!!

Clear skies mate!

FAAMAN... I had the Phantom in the works and here's a few pics of the mockup.... I like the polyhedral on the wings and seems to make her a bit more stable in the air. Glides pretty good across the living room so far. We'll see how she does outside on the cat. This one has wingspan of 8 and 3/4 inches. a bit bigger than the Banshee. Going to go with a Marine scheme dark navy blue and yellow.

The Banshee s one of my old favorites that I've nearly forgotten about, another being the F-101 Voodoo. Just about all of the early jets were SUPER good looking, and you've done a good'n on this one.

I haven't had much time for the catajets lately in spite of the "good" building weather (read: crappy outside) with finishing some leftovers and getting a model fini for the upcoming contest (my first indoor) in November.

Hope the Banshee goes well on the sling.

Sneaky Tom Grin. Your Phantom looks great to me, how much did you enlarge the tail feathers over the original? Betcha she goes real good "under power' from the cat. Cool colour scheme as most FH-1's were relatively plain in their finish.

This catajet 'thang' is getting out of control guys, even my kids are making suggestions as to what'll do well. They seem to like the weird ones Cool , here's two from them.

Enjoy, light winds,

Neil
