Having discovered what Mitchell prescribed for the Spitfire (which can’t be all that bad, I decided half-bad was better than sharp corners, so went half way…….  The method was to fit foam forms to the flap area and carve a suitable shape which would slide the fillets under the GraSing ones at the trailing edge. PLUS I thought the fillet, when flaps extended, might serve partially as a fence to prevent unnecessary air being dumped off the flap………. Maybe not.  

        I have uploaded 4 photos of my project. showing the installation of fairings/fillets.  

        Go to the EuropaOwners gallery and I'm about fifth album down  

        The series shows (I hope) fourth, a mod to one flap inboard end. The fillet slides under the trailing edge end of the main fillet, visible in the first three shots. I began with Graham Singleton’s excellent fillet set, and embellished by extending the function to the flaps.  

                Further explanation, on demand.  

Cheers, Ferg

Hi Ferg



"The method was to fit foam forms to the flap area and carve a suitable

shape which would slide the fillets under the GraSing ones at the trailing

edge."



For what it's worth I remember hearing that filling the flap close to make

the inboard side flush caused carbon monoxide to work its way into

cockpit.

Fergus

thanks for the kind words but imho Ted's fillets are better, he has 

small radius at the LE increasing as the fillet extends aft. Since the 

boundary layer also gets thicker as it moves aft there seems to be a 

certain logic in that. Look sexier too.

Ferg,

 Regarding the "pyramid" that is attached to the  fuselage at the trailing edge of the fairing, these could be made detachable  (screws or Camlocks) to enable the standard trailer to be used. For my own  situation, I found it more convenient to modify (temporarily; it was someone  else's trailer) the spar supports on the trailer, so that there was no conflict  with stacking the wings. As I recall, this remained road-legal for the UK  (7'6").

on G-KWIP there was a smell of exhaust only at low speed with the flaps 

down, the flap slot was closed by the fairing flaps up

Very nice touch Ferg...



I'd very willingly trade my fillet-dreams for having my build as far 

along as yours; you must be just about ready to get some air time...(?)



Happy landings,



Fred
