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?

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.

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.

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.

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.

The wooden core would allow for some compressibility, but it would be minimal.

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.
