Foxacoy Powerhouse part 4

Hi Guys,

Well the scaled down Sal Taibi Powerhouse for the Foxaco Event turned into a Plane Jane.

Tom Ryan said he would bring his spray gun & spray the tips of the flying surfaces with Day Glo Pink.

Tom sent the Sky-scrapers Decals, one of which I used on the wing.

Tom's father, Frank, wanted photos. He is getting photos along with the rest of you guys.

Plan on flying the Powerhouse next Tuesday, August at Shelby, Ohio. Then fly it at the SAM 40 Contest at La Salle, Michigan on August 5.

Nothing like cutting it close. Bob Erpelding suggests that I make the checkout flight at La Salle in the morning. Now that is really cutting it close.

The weather has been terrible for flying this year, so I have been building.

The Speckrum DX5e radio is installed. It is a nice simple 5 channel radio. Also Cheap!

The locater radio is also installed, just in case the old eyes fail or in years passed, Tom McCoy put a hat over my face while flying a R/C 1/2 A Texaco. I lucked out and spotted it. I was flying proxy for the Contest Director, Jack Brown. Also won the event for Jack.

More photos. The wing has three coats of nitrate and is waiting for the 50/50 mixture of Duco cement and nitrate dope on the undercambered ribs. I am going to silk the model, white on the wing and stab and black on the fuselage and rudder. I ran out of my favorite covering material - Polyspan. Gene Wallock told me (ordered me) to use acetone to attach the silk to the framework.

Some sanding required on the stab and rudder before covering.

Gene told me to split the hard 1/4 inch square balsa for the longerons with a band saw to make the bending a whole lot easier. Also insert 1/32 balsa to take up the space made by the band saw blade. Insert the 1/32 balsa perpendicular to the workbench and then make the required bends. After making the bends glue with thin CA. Cut and sand the excess 1/32 balsa. This was a really good suggestion by Gene. It was slick as snot on a door knob.

Notice the Tee Dee 020 on the plans. Tom had the plans blown up from Gene Wallock's 020 plan of the Powerhouse published in Model Builder Magazine back in 1974.

Next big job is finishing off the fuselage.

Hi Guys,

The wing took a little longer than I planned on. Covered the center section with 1/64 ply.

The wing as is weighs 12 ounces

The first photo shows the dihedral jig I made.

The wing is hanging up waiting to be covered.

I ran the Fox 35 with the APC 10.5 dia by 4.5 pitch prop. It tacked out about 11,500 rpm. Installed the Tongue muffler and the prop tacked out at 12,000 rpm.

But the engine was running a little hot. I backed off the needle valve and it ran cooler at 11,500 rpm.

The stab is the next thing to build.
