Not a bad read , if a bit long winded . Griffon ( Big Block ) Spitfires .
Flight Anaylisis / Performance , and foibles of the vasrious models , mark by mark . And Seafires .
Other Half seems to be multitudinal pilot accounts / action etc etc .
So for the technically inclined , or those intrested in Aerodynamic Dynamics , engineering , and durability / development ,
Itsa notta too a the bad , eh .
From the Library , of course . A E book comes up on google , if your that way inclined .

I have a WWII copy of the Spitfire Pilot's Manual. In addition to showing the location of all the cockpit controls, it has a section related to the peculiarities of the Spit. One advised, in case the landing gear doesn't come down properly, to attain altitude and perform a "Split-S" maneuver. This is supposed to generate enough "G" force to pull the gear down.
-
Floyd, Did it say to have lot's of altitude before doing a split S? Back when I was learning aerobatics in my single place Starduster I split S out of my first slow roll and lost allot of altitude and pushed close to redline. Richard

Might be a good time to look at Joe Adamusko's Seafires and Spitfires...enjoy! PhillySkip

Looks like the first one would be Griffon powered by the bulge at the exhausts.
I have a Walter Umland Spitfire kit waiting for my building and flying skills to come up to the task.
-
When it comes to scale exhaust stacks, this one is about as far from scale as you can get. These exhaust stacks were salvaged from a smaller model, and are laughingly small! Fortunately, it doesn't detract from flying.
-
It's still a great looking plane, Floyd.
The Spitfire is my favorite plane, by far. I think I have 6 models of it waiting to be built, from CL to 1:72 plastic.

Bill I think Joe's Spitfires and Seafires were built in collaboration with "Windy". One of them is powered by a .90! They fly beautifully!....PhillySkip

I hear ya, Bill. I've got flying, pladtic, foam , Seafires, Spitefuls, Sea Fangs, Spitfire float planes, so many models of the gorgeous Spitfire.
If I win the lottery my friend in England said he'd restore me his Attacker wing, we'd convert it to boil off reservoir for a Griffin Unlimited racer Spiteful hybrid!

Think the " Hawker Spitfire " cooling system might be the trick !
A Mk 18 fuse , teardrop canopy , intermediate size empenagge , and the attacker wings ( Gimme ) would likely be ' the most efficent ' Reno Racer
( as its smaller area would be adquate in turns , as would the ailerons , at those speeds . Build in a bit of washout though . S?P )
one could come up with , which is why I was going to scour Pakistan for some Attacker wings , as there were a few there once .
A Napier Sabre might be a hotter set up though , as late series got 3050 Hp .Thing Above got about 485 with full military equipment ,

Boil off is the best, easily lowest drag and with the latest tech well controlled.
Griffons aren't the best race engine but I like them and good for 3200 hp. The contra-props off of the Shackelton have at least proven to be fast in modern terms with proper shaping of the blades.
Smallest stab, man. Low wetted area , adequate vertical area with a Sea Fang vertical and ventral fins.
Griffon Tempest and Tornados are good looking though air cooling is no way to race a liquid cooled engine these days.

Hey Chris,
I can't wait to see you in a Spiteful.

I have the Brodak Spitfire waiting to be built and I live just outside of Edmonton, Alberta. I have looked at this particular paint scheme for some time now but couldn't figure out the colours....you just solved that for me! Thanks! H^^
