Well, it appears there are going to be three 1/8.7669 B-47's.. This makes five B-47's in three sizes out there in various stages of
completion. Two built up, three composite, 1 of the 2 built up is complete-ready-to-fly but remains grounded. Good to see another
one in the bones (1) How do I contact Bernie?(2) Is Bernie web enabled?

@1/8.7669 there is 5.125" of rearward inboard flap travel. We are currently integrating Fergilli linear servos to achieve this because
I want to break the wing into four sections, inboard two are affixed to fuselage except during maintenance.



(3) What was Bernie's canopy on originally? I need the windshield section of it.

So Bernie finally has the flaps worked out - zero to 40 degrees throw using three Hi Tech servos in the LE. The key is the two rods connecting on the servo arm. One to extend and one to droop.

I like the flap design, it's all in the servo arm, the my rod changes the angle and the metal rod acts like the flap track. Sweet, wish I would have thought of that...

Cheers,

1:1 Flap & Flaperons

The flap leading edge to trailing edge is 5.125 inches at this scale. How did you pull that off with a servo arm?
Apparently your flap depth is somewhere around 3.5" front to rear?

Below is the inboard flap/flaperon hinge mechanism. It is attached to the rear spar with a hinge on its bottom
side permitting downward only movement from a centered position.

The flaperon hinge line is mounted to a beam which moves rearward along the flap track.

Eric,

The flaps on the B-47 move rearward as well as turning down to a maximum of around 30%.
