Not actual building, but some research. It’s amazing what the FAA TCDS’s can tell you. For one thing, I might need a new governor. The one on my engine is a McCauley C290D3/T18. This means absolutely squat without some real numbers. For instance, the drive ratio is .895:1 and the torque range is 120-1200 in/lbs. Why is this a concern? Because if that McCauley turns out to be trash, I’ll have to pick up a PCU5000x, which is pretty freakin’ cool, but the application chart doesn’t spec my governor, exactly. Maybe I’ll have to replace it, maybe not, but I like having options. And just for future reference, here’s a link to the TCDS:
