Scale Wendell Hostetler 30% Piper Cherokee Glass Fuselage Build.

[TonyHallo]

It is Evergreen Models 1/4", the shapes come 14" long.

Laid up one layer of 1 1/2 ounce cloth and 1 layer of 5.7 ounce carbon on a sheet of glass under vacuum for for the subfloor. Thinking this will let covered with a gray vinyl or cloth. Need to see what is available at Walmart or Michaels. Cut and fit the baffle at F2, this will keep the hot air out of the cabin area. The baffle was a lay up done for the engine baffle but a little too light. It will get a coat of flat black. I used the .020" styrene sheet for the template for the the floor, works great, cuts easy with a knife.

Tony all the details and everything you build into a plane how do control your final weight. That is always a challenge for me. If I may ask what WQL do believe this plane will end up being.

As far as weight goes, in the photo below last March, weighted 18 pounds, without engine, 8 servos, receivers, wiring, batteries and paint. My goal was 30 pounds which yields a 8.9 WCL, thinking that 32 to 33 pounds is more in line which is 9.5 to 9.8 range. 34 pounds is a WQL of 10. These WQL's are well within sport scale range. The wing is 14 % thick at the root so that may provide some additional lift.

Engine with starter, ignition and exhaust - 6 pounds
Servos - 1 pound 3 oz.
Radio equipment - 4 oz
Seats, floor panel, and F2 baffle- 16 oz
Wire - ??? there's a lot of wire in the plane, distributed use of the recievers to save weight where possible, i.e. the lights are controlled locally by the receivers mounted in the wing tips and vertical fin, also used 28 gauge wire for SBUS and Sport signals
Paint - ???
Batteries - 12 oz

27 pounds identified above, paint is unknow at this point but I think I'll be happy at 32 pounds. I vacuum bagged every part that I could, that saved at least 2 pounds

Wow thanks for that for all the details and the scale stuff you build into the planes the plane is light at a WQL of 10 or less is very good.
