    Scale Wendell Hostetler 30% Piper Cherokee Glass Fuselage Build.

    It ends up the prop shaft is long enough to accept a full nut of an elastic stop nut without the prop washer. I bored the 10 mm hole in the prop washer to 1/2" and turned a step on the stop to fit the hole. There's no need to enlarge the prop bore as I had previously planned. I made a few...

    Do your plug temps reach 380f? I have my alarms set at 300F.

    Scale Wendell Hostetler 30% Piper Cherokee Glass Fuselage Build.

    I read over on another site that a fellow had broke a thermistor while making up plug temp sensors. I have made them in the past with success but could very easy see how one could break the thermistor while cripping to 10 mm lug terminal end. While making up the 3 watt position lights, heat...

    Electronic Carburetor/Roto 85 FS Install

    Not quite, the controller reads the pulse width from the throttle stick, separate channel from the throttle plate. The pulse width is converted into the solenoid pulse and corrected for ambient temperature and pressure. So in my case I have the throttle plate on an exponential curve and the...

    Electronic Carburetor/Roto 85 FS Install

    No regulator, the carb is just like a Walbro. Basically the solenoid replaces the needle valves. There is a pump and diaphragm on the carb.

    Electronic Carburetor/Roto 85 FS Install

    Have the carb mounted. Used the original heat insulator and made a new one 3/8" thick out of G10 material. Since the solenoid pulse width is set by the throttle I want accurate and repeatable throttle opening. The throttle servo is controlled via a exponential curve as normally done with...

    I had those wires on my Champ and as indicate they are great. You have a bundle in wires alone!

    Do you need the switch because the batteries remain in the plane?

    Don't understand your comment about toggling the switch. I my last setup, the ignition power came off the balance lead on one of the flight packs through a 5 volt BEC to the optical switch near the engine. No switch.

    I assume you are talking about the Smart Fly optical system, used two over the years and they work great. I take my batteries out to charge them even since a fellow flyers van caught fire in his driveway while charging the batteries inside the plane in his van. I ended up with a transmitter...

    Added the filler behind the latch. Woke up one morning last week and thought about the small brass dog bending with use since brass sheet is annealed during the silver brazing. Made a new latch out of steel. Also fitted a strike plate to the jam. The door will close without opening the...

    Don't know if you are using a TechAero IBEC or not, that would eliminate the ignition switch and battery.

    Electronic Carburetor/Roto 85 FS Install

    Built the electronic control for the ZAMA carb used on the Sthil M-Tronic chainsaw a few months ago. It uses a Seeeduino XAIO board and programed in Arduino. There is a GitHub site describing the project and quite a few discussions on other airplane sites. The original project involved using...

    Keeping the air in contact with the cooling fins is key. Looking at the Kolm 3 cylinder photos, there's a lot of stuff going on the intake/exhaust side of the engine. I would make three layups the shape of the cylinder and attach those to a flat plate opposite the intake and make that the high...
