The initial
part of the flap build can be seen on the stub wing page . A piano
hinge with removable pin attaches it to the rear spar.
The flap
will be operated via a linear actuator behind the seat which will
rotate a torque tube. This tube will exit the fuselage just
aft of the
rear spar and pivot the flap down via an arm attached to rod end
bearings and in turn, the flap. It will be
a similar set up to that of Jeff
Scott's. |

Here
I have joined 2 HF-2A rod end bearings with a piece of 5/32" thread and
some Loctite. These bearings are smaller than the MW-3 ones
used
on the elevator
and rudder and
were in the AS&S bargain bin for under a buck each. I
bought
10 knowing they would come in handy one day......sure enough! |
 |
The edge
of the flap has a 1/4" layer of flox beneath the full length and a 1
1/2" deep pocket of flox where the bolt hole has been drilled and the
double ended bearing screwed in. |
 |
I use the
grinder to scuff up the piano hinge. It gives the flox better
"bite". |
 |
The
good old nylon breadboard makes a fantastic bearing surface for the
flap torque tube. The fuselage has a 3/4" drilled through and
the
round cut nylon bearing has a 5/8" hole. |
