Ed, your proposal to produce the fairing bobbins is great. Please make me a
set. Do I infer from your message that you are offering flight experience in
your TF? If so, what airport are you located on, and when can we come? Ken
Melvin, N51KX.

Ken,
I'll get the machine shop on it on Monday.
I intend to have the prototype TF available to any qualified FEW builder as
soon as it is back up (currently fitting a new engine and rewiring / replumbing
as needed).
Camarillo, CA (CMA is the identifier) will be the aircraft's home base.
Ed

Guys,
A huge "gotcha" got me this morning. As I was doing a little maintenance on
the prototype I found that I could turn most of the 10-32 nuts (bolts have come
loose over time) that are on the inside of the fuselage behind the firewall.
These nuts are on the bolts that hold the bathtub fittings to the fuselage
longerons in four places. These mounts are what the engine support frame bolt to.
When this fuselage was built, these 4 fittings were bolted in, foamed and
glassed over, and forgotten. Now after a bit of flying time the bolts are loose
and there is no way to tighten them without digging out all the glass and foam
that covers them! I suggest that you either leave them exposed so that you can
get a socket on them in the future, or put the bolts in without washers on
them (from the outside of the fuselage in), put a small tack of weld on each
bolts head (one flat would be plenty) to the fitting with a TIG welder after they
have been tightened. This would enable you to reach in and snug up the nuts
at any time, even if you have completely covered over the fittings as the
prototype has been. I would expect these bolts to loosen up in any case due to
the
fact that they pass through a lot of composite material that will crush
slightly over time. I would also "pot" these fittings in the fuselage pockets with
epoxy / flox when you bolt them in for the final time to reduce any extra
movement that would tend to elongate these #10 holes.

I figured that would happen so I filled the fuselage voids with White
foam blocks then covered that with structural adhesive it's no big deal
to cut out the foam if I have to. On the inside I have not covered the
nuts with anything.
Ed, on another note what is the weight and dimensions of the engine the
plane is based on.

This is very worrisome. The Prototype doesn't have that many hrs on it,
does it. Has it flown its 1st 50 hrs?
There shouldn't be any compressible foam between the mounting plates.
According to my (scant) instruction drawings and recollection, that should be
solid glass plys. LRE

I found a composite construction when I drilled the holes, outer layers
of Fiberglass, then a layer of steel sheet metal with a wooden core. The
wooden core would allow for some compressibility, but it would be
minimal.

Hi All...
I'm really new at this email website stuff so just bare with me.
I'm in the process of building my wing. I have all of the ribs and bulk
heads in. I have the fuel vent tubes installed. I have the flap motor
installed and working. I'm getting 40 degrees of flap travel. I have
the ailerons mounted and the push rods ready to weld the ends. The tail
section is finished and ready to close the Horz Stab, elevators and
rudder. The mac servo's are installed and working. I do have one
advantage I have the Proto Type Fuselage Little Friend One. So mounting
the tail section was good just hope the wing fits as well. I'm now
waiting for Ed to send me my gear. I do hope you FEW builders will use
this site to become excited about your plane and start building again if
you have stopped. You know we FEW builders are the only replica 51's
out there that has some one who we can get information and help from.
so lets get the plane in the air and meet some place and have some plane
talk. More later as it happens. Gary Gerber
PS Any of you are invited to come to Syracuse, IN to visit. Goshen
airport is just 10 miles from home.
