This kit was mentioned in a past thread. I came across a photo of mine. Built around 1969, I don't remember its fate.
-
those were very good flying models and you could add flaps if you wanted?
-
My dad built me a Sterling 1/2a Mustang with a black widow way back in the gap..... Very nice :)
Altho I never seen one of these!
-
They had 3 models.
a cosmic wind, a mustang, and hawker hurricane.
24 " built up wing, 144 sq in wing area.
-
Anyone have plans or patterns for the Hurricane? I would love to build her again. H^^
-
yes, and no.... I had made copies of the whole kit. I'm 2500 miles from storage and not sure if any of it survived the many moves. I do know the spars had gotten broken. and now clue if I kept them.
I might still have the original plans ut the drawing was just 1/4 scale.
Sorry, I did like the planes.
-
I can work with 1/4 scale plans. Anything will be of use. H^^
-
but they are in my rv I think... 2500 miles from where I am now. sigh.
-
If your RV was smart enough, you could call it and tell it to come visit you! LOL

I built and own a p-51 that my dad gave my son a few years back when he first was learning how to fly. My father had the kit for what I believe was 25 years. I get a funny feeling when I build a kit that I know is not easily replaceable. I didn't trace anything , just built it. I was trying to explain to my son how its important to trace the parts so you have future copies and references. He has about as much of an attention span for building as a brick wall does. Well anyhow the kit got built and I painted the entire plane olive drab. I figured simple works. I somewhat reconfigured the outboard side of the firewall for a Perfect tank and installed a Sure Start. The plane flies fair in my opinion. I look back on it now as others would only commend how it flies. I think when you look at the choices that were available for the times, yes it flies well when compared to those of the same vintage. I just wasn't real impressed with the flights. I find that a Baby Flite Streak which was available then would surely outfly any of the models and also most of today. The plane isn't as light as I know I could make it if I was to make another. It uses a very large piece of ply for the landing gear in which you stitch the gear on with copper wire. This in my opinion is a problem as far as weight is concerned and surely there are better ways. The gear is also at a poor angle as it exits the wing as it constantly noses over and bends. After working out a few bugs, I did have it trimmed out well enough to fly decent. I just enjoy models that I grew up with and remember. My son on the other side is after instant gratification in which most of the models of yesteryear just didn't have. It took a bit of finese to make things work in your favor. I still think the plane doesn't get enough attention that it should've earned. I recall American Modeller featuring this plane and a few others around 1974. It did make for a good review with a lot of positive comments. Ken

I had built the Hurricane and powered it with a McCoy .049. One thing I remembered about the kit was just about everything was included in it to build it. I had used the McCoy so much I had to squirt oil into the cylinder before priming it with fuel to get compression. Also made a large version of the model, 36" Weber diesel powered, that I never flew. That one had rib caps and flaps on it. ;). Both had Aero Gloss camo paint jobs.
-
were these airplanes based on a baby flite streak? Looks like the same size wing.
If so it would be easy to make your own.
-
NO. wing was kind of like an eggcrate.
1/2 x 1/8 leading edge. 1/16 slotted spar tapered and noteched trailing edge.
1/8 plywood center section that tied the bellcrankand leading edge and spar together.
it also served as the landing gear mount.
-
here is an estimate drawn on 1/4" quad at 1/2 scale
-
I drafted a wing design based on Jim's sketch. The design is a bit different. I can do the slotted "egg Crate" type wing but not on this computer. When I can get to the right machine I'll give it a go. Also the wing came out a bit more than described counting the flaps. Without flaps it is 140 sq in. The attached PDF will print on standard letter paper

I did notice teh LE sweep.....
Wow must be hard not to be nose heavy.
-
Ok here is the fuse and stab for the Hurricane
-
Where did you get the dim's from ?
The topflite models had a built up wing.
I was gustimating from memory.
-
Jim,
I took your drawing, put it in my CAD, scaled it to 24 inch span. I used those dimensions then for the wing and stab. The fuse is a tracing from a 3 view. It matches you drawing well and turns out to be near scale.
John
P.S. You must have a good memory because it looks right to me.
-
Ah ok, I do cheat because i pulled a 3-view to kind of estimate shapes. Did redraw the rudder a few times.
I do know i have more ribs than the original. I think the 2 center should be about 1/2 to 3/4 apart and the next 2 made the outter edges of the plywood center section. leadout guides were those funky 90deg/ angle things with 1 hole on each tab. landing gear was wired to the plywood center section. belcrabk was typical 1 1/2 or 2 ".

Here is an update of the wing using the strip LE
-
Randy Heydon clued me in that the plans are in the AMA plan book Volume 1. Hurricaine, page 40, P-51 page 60, and Cosmic Wind page 62. The baby Flite Streak and Combat Kittens are also in that volume.
-
These were great. Designed by Dave Platt. A Cosmic Wind just went on ebay for $55.00. The series was called "junior aces". Hurricane, P51B and Cosmic Wind. AMA kit plans don't show all parts. Nice box art too. I think the wings were all the same. Wing mounted gear. I wish there were plans showing the parts. Great flyer. Cool to look at. My favorite 1/2a of all time.
-
Randy scanned in the plan and sent it to me. Let's see if I can post it!
-
Larry, thanks to you and Randy for the plan.
A word of caution though to anyone trying to use it. I loaded it into my CAD to update my wing design and found that the wing has some negative incidence relative to the stab. I doubt TF intended this, it is probably an error on their plan.
PS I overlaid a p-51 fuselage on the TF Hurricane plan. The P-51 is exact scale so the TF fuselages must have been very close to exact scale. The dotted lines also show the incidence problem.
-
So the plans I drew from memory are real close to the actual plans...
-
jim,
pretty good memory
