So my hobby project had to be suspended when my wife had a series of hospitalizations. My original plan was to rebuild N19WT in a large storage shed but I've become her primary care giver and need to be at home. But if Muhammad won't got to the mountain: N19WT - Rebuilding Log The next phase is to build a fire-wall forward engine and cowling test stand. I'll use this to build and integrate everything forward of the firewall and test: Actual weight - a fully integrated engine, radiator, and controls. Critical for weight and balance and to finally document the replacement weight of engine, radiator, propeller, and cowling. Radiator ducting - a key part is making sure the cooling air has no turbulent before the radiator to maximize pressure gain. Engine-by-wire - this will be a fully automated system. In particular, throttle trigger on the center control stick. Everything else will be firewall forward as an integrated assembly but the cowl flaps and cabin heat will be mechanical. Bob Wilson
