    Canada - Journey book - Annual Maintenance record

    For my Canadian amature homebuilt, the annual maintenance record go in the Journey book, correct? I have the initial comment during building, "This aircraft will be maintained in compliance with CAR 625, Appendices B&C" in there. I saw on MD-RA site it says all technical records for airframe...

    Exhaust within subcowl

    I'm just in the process of building a teardrop subcowl for under the plane. My oil & coolant rad outlets will be dumped into the subcowl, so they can be streamlined and spit out the back. Along with it, the exhaust will flow through there. My idea is to add louvers when the exhaust pipe enters...

    Electronic fuel 3-way valves

    Hi, I'm looking to simplify my fueling system during my design phase. I'll have an auto engine with 4 fuel tanks in wings (supply and return lines for each tank). Trying to fit 8 hoses (4 tanks x supply and return) to a manual fuel selector isn't out there. The closest thing would be Groco...

    Designing new Aviation ECU

    Hi Homebuilders... In my conquest to build my first airplane, RAI-1 XR “Tango XR”, | Revolution Aviation Inc., why not go all out and build your own engine (Rx8) and ECU. This thread will be the R&D of an ECU designed for the aviation rotary. We honestly don't have many options out there...
