    Scale Wendell Hostetler 30% PA-28 Cherokee Build

    I'm happy with the way hinges turned out. I plan to use the clevis from a DuBro HD adjustable control horn for the connection at the flap. This requires 3/16" thick material, thought about aircraft plywood but decided to order a 6" X 6" x 3/16" piece of G10 from McMaster Carr, should be here...

    Scale Wendell Hostetler 30% PA-28 Cherokee Build

    I follow the X20, Tandem & Ethos thread, pretty sure I read every post, last year I decided to buy a Taranis 2019 SE so I don't expect to ever use Ethos, not sure why I continue to follow the thread? Excluding the touch screen functionality, I can't believe that Ethos will ever do any more for...

    Scale Wendell Hostetler 30% PA-28 Cherokee Build

    I wonder too. It looked so good on paper but just didn't work as expected. If I had an Oscope I could check the it out. That's OK because with the OpenTX timer there will be fewer parts since I had planned a PWM switch anyway. The switch will be switched by the timer in the TX, so simple...

    I was unsuccessful at building a timer circuit using a LM555 timer. Not sure why it did not work but I made 3 different ones with the same result. Not to worry as a timer is very easy in OpenTX and all it takes is one logical switch, the timer is adjustable to 0.1 sec so it's all good. I...

    Working on the tail lighting, the mount for the beacon is made from a 5/8" dowel, the lens is from a 1/2" panel light and the bezel was turned on the lathe out of 5/8" aluminum stock. The tail position light mount is a 1/2" dowel with a 10 mm 1/2 watt LED. The mounting flange is removed from...

    @AKNick, can you send me the schematic? Isn't there a web site that will make a board from the schematic? Or at least I thought so? @WMcNabb, my build is rather simple, only blinking light will be the vertical fin beacon. For more complex options the Eflight controller looks to be the ticket.

    Scale Wendell Hostetler 30% PA-28 Cherokee Build

    Been searching the web for a few days looking for a LM555 circuit that has adjustable on-off times for the the red blinking beacon on the vertical fin, finally found one here. For $8 got enough components to build 4 timers. Flew home from Texas last week and studied the blinking beacon on the...

    Scale Wendell Hostetler 30% PA-28 Cherokee Build

    Worked on the flap hinges and aileron linkage today. The hinges were cut on the mill, oversized blanks were cut and drilled in a stack, a 1/8" rod held them in place while the machining operations were carried out. These will get glued in after the wings are treated with Monkote. The aileron...

    Was out of town since last week so not much to report, finishing the right wing flap leading edge and started hinging. The red and green lenses arrived and started making a plug for the wing tip lights. Nothing fancy, copying a Whelen light. Will make a mold and lay up two tear drop shaped...

    Pre-bent 1/8" balsa around an 1 1/2" pipe for the flap trailing edge. The stub ribs and sheeting were sanded to fit the pre-bent sheet. The flap leading edge will be 1/4" balsa sheet then sanded to close to an airfoil shape. Will make the wing side flap hinges (shown below) out of 1/8" g10...
