I built a large TSR-2 many moons ago out of depron for pusher prop, due to prop clearance issues it never flew.

so i have decided to fit twin edf's in the original, so to gain some flying experiance i have decided to build a small tractor prop version out of HK foam board.

Build blog to follow.

I started by cutting the fuselage sides from 10mm foam board.

each side had to be made up from two parts, so i added a doubler to strengthen the join.

then i started adding formers cut from more 10mm foam board.

you dont need many formers as the 10mm board is quite strong.

i added some more 10mm sheet to the underside of the fuselage to add support while i cut more formers.

then the rear end was pulled in and a notch cut out to take the tailplane.

more to follow if you are interested.

Yup, following with interest.

I've looked at this a few times in the past:

the tailplane was cut from one piece of 10mm and two lengths of 6x10mm balsa were cut to act as hinge spars.

the spars were cut to length and stuck in place with Uhu por.

i then sanded the leading edge to shape and sheeted the top and bottom of the tailplane with 3mm foam board.

the idea is that the 3mm overlaps the balsa spar and helps to hold it all together.

the main wing was done basicaly the same way, except that i added some foam spars and a couple of ribs to help shape the airfoil section.

i 3d printed some dihedral braces to set the tip anheadral and then fitted some thin spars before sheeting the tips and gluing them on.

the wings were then put to one side, so i could get back on with the fuselage.

Nearly finished.

you would not think there are only 25 years between these two aircraft.
