The newest version of the Spitfire from Durafly. This version with much improved scale detailing. It can certainly handle the wind. Can't wait to fly it on a calm sunny day.

The Spit looks right in the air, albeit a bit light, typically foamy. I understand the retracts are ali and nylon, not the usual brittle plastic, is that correct?
I have been contemplating getting one, until Parcelforce lost my previous Hobbyking parcel, (separate thread!) so until that is resolved, I'm not ordering anything from them.
I' pleased that you mentioned the ball links instead of clevises. I'd have to send for some suitable pliers as well!

if you are calm and collected when all about you are going berserk - you've missed something important!

It was the worst day for flying really Eric. I wouldn't go by that. Hoping to get SOME sun in the near future so I can so nice low aeros with it. You will have noticed I hadn't taken the front protective film off the decals either. Very embarrasing. Have done that now and it looks superb.

In the video you said the flaps descented quite a bit - looks about 30 degrees - but of course on all Spitfires (except the Mk47) the flaps only had two positions 0 and 60 degrees - unless the "for take off only" wooden wedge trick was used! ;)

As Q put, they were air-brakes, not flaps, to slow the slippery beast down!

It's 136.64 Gbp from the EU warehouse Stephen, looks like Durafly make bespoke units for HobbyKing.

Do it now, you may never get another chance

Dom said he flew it on 4S, Klippy, but it will fly on a 3.

In May 1942 the USS Wasp and HMS Eagle carriers went into the Med to deliver 64 ordinary land based Spitfires to Malta.
The Spits had to have over load tanks to give them the required range.
To help get them off the deck they needed 15 degrees of flap but the pneumatically operated flaps only had two position 0 & 60 degrees.
The pneumatics cylinders only worked one way so the flaps had a spring return.
Just before take off the flaps were dropped and wooden wedges held in place so when retracted they were held at 15 degrees.
After take off the flaps were fully deployed, the wedges would fall out and the flaps could then be fully retracted.

Flap travel of all the Spitfires I've flown was closer to 90 degrees, not 60 degrees, Q. I seem to remember that 85 degrees was the figure, but I'll check*. You're right about the use of the wedges, though.

With such a large flap deflection, they cover the outlet of the radiators and on the early marks, the oil cooler, which makes it a major problem if the flaps don't retract. One of the good design points, though, was the trim. The aircraft pitches down significantly as the flaps are deployed but the pitch trim remains about the same, indicating that Mitchell got it right!

*Addendum - the Spitfire Mk V manual gives the down position as 85 degrees.

My mistake.
I was relying on memory - should have checked! ;)

I second that, we don't speak German largely because of him! I still get goose bumps whenever I watch the movie of his life!
