Re: Spit Ailerons
From Cheif Test Pilot, Jeffrey Quill's book "Spitfire-A Test Pilot's Story"
Paraphrasing some of this. He speaks about the problems with the metal ailerons and how they were almost completely stiff in a dive of 470mph. His experience with the Spit I while flying in the B of B with 65 Squadron only heightened his concerns and what he saw as the need for metal ailerons.
When the first metal ailerons were introduced they let some veteran pilots try them to see their reaction. "All Pilot's agreed there was a vast improvement in aileron control, the only criticism being that now control was a little too light."
Interestingly, I just happened to come across a quote from a service pilot today talking about the FRXIV. "The first loop I ever attempted in the aircraft was the most shuddering affair I can ever remember, as you had to 'motor' the machine around on the Griffon engine throughout the manouver. Conversely it's rate of roll was astounding!"
So I guess it comes down to a pilot's perception of things. Jeff Ethell was flying Rudy Frasca's full span wing MKXVIII TP280 when he wrote about the Spit. A much heavier beast then a V or an IX obviously and without the clipped wing the roll rate would have been less.
Quill's book spends a lot of time talking about the longitudinal stability issues too and the introduction of the bob weights to the elevators. The structural failures that were happening prior to this had to do with incorrectly loaded aircraft that upset the C of G.
AS for getting off the ground in a Spit, I remember Pierre Closterman talking about taking off in his fully loaded Spit IX in front of some P47 pilots, in about 50 yards and slow rolling it on the deck as he pulled the gear up just to show off.
As for stall characteristics. Whenever I've read stuff by Spit pilots or talked to them, one of the comments made is the Spit always gave a lot of warning before it stalled out. With the lower wing loading of that big wing, it's not a huge surprise. It also had a lot of "float" on landing because of that. But it would shudder and then gently drop a wing when it stalled.
Bottom line is it was a heckuva fine combat plane, as were many others of it's contemporaries, regardless if you want to like it or not
