    Scale Wendell Hostetler 30% Piper Cherokee Glass Fuselage Build.

    After calculating the required length for the engine standoffs to provide 2 down and 2 right thrust I determined that I had no aluminum stock to make them! Ordered 3' length of 3/4" and 7/8" from McMaster Carr, should be here today. Moved on to hinging the wings. The ailerons are hinged on...

    Was wondering about the location as well, you have the ignition module blanketed with foam, recently read somewhere that mounting the module upside down is the best since the bottom runs hotter. Made sense as heat is not electronics best friend.

    Heading to Fla next month for a few days, painting season is not far off, would really like to paint this bird this year. Missed a great flying day today, 74f in the burg, winds light and variable.

    Mounting the cowl today. Using a cowl ring, the top two holes will be accessible from the air inlets and the bottom four from the cabin. It was areal pain glassing the ring to the cowl through the front openings. Ended up using long reach needle nose pliers to the place the small pieces of...

    The door came out nice and really stiffen it up. Happy with it now. Have the 1 1/2 ounce cloth on the flat surface, once cured and trimmed the flange area will get glassed. Cut the left aileron/flap free and installed the 1/4" balsa trail edge, once the right is cut will begin cutting the...

    If you were to pick one up, how is the tax or duty handled at the border? Just curious. When I was child my family visited Niagara Falls, Canada. My older cousin traveled with us and he bought a pack of small firecrackers there, my dad put in glove box. When we were crossing back to the USA...

    I hope to build a second with panel lines and rivets in the future. I plan to fly this one in the AMA Pro Am class where the judging is mainly on the pilot. This is a proof of concept so to speak.

    Put the corrugations in the aileron and flaps today, there are 72 corrugations for the ailerons and 89 on the flaps. Glued up a fixture to use with the Dremel router attachment, it looks kinda crappy but it worked very well. The fixture has three points of contact had held the router firm. It...

    Was hoping that the engine and cowl could be mounted to the firewall before it was glued in but that is not the case, even the smallest #0 screws interfered with the cowl so it was epoxied in yesterday, the holes for the nose wheel bearing block were drilled beforehand. Think I will use the...

    While the SuperFil was curing started working on the interior finishing. Plan to make it like the full scale with a flange around the windows and some depth below. As the vertical strips around the window are added, the remainder of the window openings are cut out. A majority of the windows...

    Along with hinging another one of the tasks that I don't care for is cutting out the air inlets in fiberglass cowls. Always seem to mess it up then try to sand everything flat from the back side. Years ago I seen a wood worker screw a larger piece of Plexiglass to his router base. Not wanting...

    Have the left wing root matched to the fuselage with SuperFil, once cured it will get sanded down to match the airfoil. A piece of plastic wrap and a little Vaseline will hopefully keep the two parts from joining!

    Woke up last night at 3:30 and made it down to the shop to trim the cowl, was just about the perfect time, maybe another 1/2 hour would have been better. Decided to put a little heat on the mold to speed the cure. Inverted the cowl on the 12" disc sander and placed a 1500 watt oil filled...

    Got the cowl laid up. Put on 3/4, 1 1/2, and 4 ounce this afternoon, came home from my grandson's basketball game this evening and put in the 6 ounce cloth. There's over two hours of layup work on it, don't know how the fiberglass folks can sell them so cheap! There's a lot of fiddling around...
