What about a Corsair?
« on: February 25, 2011, 02:45:53 PM »
For some time a friend has been requesting a 60 sized Corsair.  Why not?  This one evolved from the 40 sized profile and the 40 sized Brodak Corsair kit.  Pushed it up to 704 squares.  No flaps (not necessary) reasonably straight forward construction, at least for a Corsair.  I might retract that last statement...
Here it is for gandering purposes:

I know your never busy. You just lay around thinking up airplanes. I want one with 3/4 flaps. All for fun.

Brother Pat,

That is great!  Is there a clear canopy that could be used with it?

Thanks, brother Ron.  Martin, I think that the Sig 11" WWII canopy may be adaptable.  This will need to be investigated.

Wow! Pat is a real inovator when it comes to WW 11 style stunt ships. I have followed his work since he published a .60 size P-40 some 10 years ago. I enjoy building from plans but kits would be the greatest. Pat, Dee, and another need to get into the 'on demand' kitting business. Wouldn't you really like to call Pat and order one of these great designs? I would.

I like it Pat, I really like it, but will you have plans available, I'm not much for kits.

I have both the plans available and the parts set up on a cutting sheet.  This is why you see the boxes around the parts on sheet 3.  I can cut the ribs, and formers.  I use all contest grade balsa and use 3/32" ribs for most any plane over 600 squares.  I have to splice the 1/8" former wood to make 4 1/2" sheets for this one.  Total cost would be:
$15~ Plans
$30~ Ribs
$22~ Formers
$10~ S&H (Priority mail)  or $5 for plans only.
There you go.
On a note about the Corsair not having flaps, the TVC is .438, which is in the pack of modern stunters.  This will do two things.  First, the "grove" will be as stable as normal stunters.  Secondly, since the elevators do not have to fight against the negative pitching moment of the flaps, the elevator will provide a very snappy corner.  The result is a very nice flying plane with very good performance.  Using contest grade balsa for components such as the fuselage skins will result in a reasonable weight for this plane.  I have every reason to think that 60 to 65 ounces is realistic goal.  My first big Bearcat weighed in under 60 ounces and is a close comparison in size and structure.  The Corsair has an advantage of losing the weight of flaps and flap linkage hardware.
This being said, the inverted gull wing planform has one slight disadvantage.  In heavy winds, the wind will tip in the outboard wing in the upwind side of the circle.  This is NOT (repeat~ NOT!) a good plane for flying in heavy winds.  Otherwise, I had a ball flying the prototype profile version.

Kirk Mullinix flew a 60 sized Corsair at the Nats about 8-10 years ago.
The plane was beautiful and looked great in the air.

That is a very cool airplane and would love to see somebody build this. Pat your work is first class and FAST. I don't know how you work so quick on these designs. Just for fun, I would like to see you do one of the Super Corsairs with the bubble canopy, the full scale type that has been restored by Bob Odegard. I know, I know, somebody always wanting something else. Thanks for the great designs Pat!

Keith,
I actually did the mods for that in the 40 sized versions.  It was a simple matter of altering the back half of the fuselage for the bubble canopy setup.  Of course, the nose needs the funny snorkel if that version is desired, but I figure that detail is up to the builder.  I may just do what you suggest.  It would only take an hour or so to pull it off.  In all reality, this is the easier one to build since the fuselage would be so easy to form for the back half of the fuselage and the Sig WWII 11" canopy would likely be a good fit.  Just a matter of setting up a second cutting file for the formers.

Pat,

I've wanted to build one since I saw K. Mullinex fly his at the Nats (saw it on video).  Even have a paint scheme in mind.
