Va speed for M-4 220

Post by Honi »

I just bought an M-4 and the pilot manual doesn't address Vx, just Vy. Does anyone have a good reference for Vx?

For my MX7, I did an experiment based on learning to fly tailwheel in the Citabria. Not sure if it’ll work with the M4, but give it a try.

Take off with one notch of flaps (which is what my manual says for a Vx climb). When you’ve got some airspeed built up, slooowwwlllyyy pull back and gradually increase your rate of climb. Pay attention to what’s happening with your fingers on the yoke. Pretty soon you’re going to feel a resonance in your fingers where the disturbed air from the flaps is hitting the tail. Check your airspeed.

For me, when that happened, it was indicating exactly what the manual said Vx would be.

Maybe that works for the M4?

Off the top of my head, I thought Vx was 70 and Vy was 90 from some piece of documentation for my M4-220....
