|Thread: B24 Liberator - 1/12th scale PSS|
Good luck with the dead-line Andy !Not much PSS on my bench lately i'm affraid...But i will try to have something new for next season,something never seen on any slope ....
|Thread: fouga magister 1/4.5 moulded from scratch|
Next week doing the second wing flap and then it's cleaning up the complete wings and glassing !!
2 : Cutting the wing and flap for about 2cm with a 1mm disc on a disc grinder. This gives a cut aprox.2 mm wide,just enough to slide some 2mm balsa in.This will provide the stiffness for the little piece between the flaps
After cutting the flaps out of the wing,i'm putting the hinge tube in just above the flap skin,then give the flap a leading edge in a way that 1:wing and flap don't touch
2 :With the flaps up, there's no gap on the upper side
3 :With the flaps lowered ,keep the gap minimum.
As you see in the foto,i first try'd to keep the scale size of the flap but it didn't work because of the difference in thickness at the root and tip of the flap.
firt draw the flaps onto the wing.The flaps are way much wider on the underside than on the top-side as you can see on the scale drawing.I have to search for a compromise because the real fouga has fowler flaps (they slide backwards)I'm not going this route as it's way to much work.I'm doing them the ''easy'' way with tube hinges.
Hi again ,before going on with the build,let's get you up to date :
After getting the second aileron in place,it's time for the flaps !
It's pretty much the same way of work if it wasn's for the flaps being seperated by a little piece of wing
|Thanks for your visit and Coment devcon1!In case i need to pull more then one out of the moulds,this will save a lot of time in the end.Cheers !|
I'm happy with this day's work and the result.Te gap between aileron(God i'm beginning to hate this word) and wing is minimal but still have some space for glassing and paint.Deflexion is possible up to 60-70 degrees both up and down without the aileron touching the wing !More than i need !
To align wing and aileron i used two peaces of gfk hinge -axle.Later these will be replaced by a full ail-span axle.
With the aileron opening in the wing cut out to big,i'm going to form a hollow balsa spar to glue in just in front of the aileron.Nearly impossible to sand this right so i'm going to use two peaces triangular balsa stock 6x6 glued to a 2mm balsa base
