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!

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.

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.

I was relying on memory - should have checked!
