20/40 Ratchet and Bent Flap Handle PIREP

Post by TxAgfisher »

That combo is THE DEAL! M4 got back in the air today and I put 3 landings on it for my currency after a laundry list of delays during annual.

I can't wait to get out and do some slow flight in it to see what it will do. I do know, that my initial reaction after today has me wondering about whether or not to install the gap seals. I may not, as it will not start sinking unless I get below 50 or so mph as it is.

I had a tendency to flare w/power a little high as I was coming in slower - a couple of hours behind it and it ought to be gravy.

I can't remember if I fired six shots, or only five.....

I agree, it is a fine combo.

Check out the gap seals that CubCrafters sells for Super Cubs. The material, though not approved, fits the Maule perfectly. Did some testing this weekend and found a big improvement. With the gap seals, I no longer run out of elevator (with me in the Maule, we are at a forward CG). Also, it got rid of the annoying Maule hop when 3 pointing the landings. Expensive but very easy to install and remove.

Now, if someone would just get it approved.

I installed the bent flap handle and 20/40 degree ratchet, flew it today. I agree it makes a quite an improvement in a already good plane. Would recommend it highly

My A&P installed the 20/40 Ratchet and Bent Flap handle on my M5. I measured the deflection and instead of 20 degrees it's 40 on the first notch and the second notch is 60 degrees. What? Any ideas why?

Are you measuring relative to the wing?

Can someone outline what the difference(s) are before/after this mod? Is the bent flap handle (which my M7 has I think) just an ergonomic improvement? What were the flap settings before the 20/40 mod?

I need to do this on my M4. It’s been on my radar for a while. How much were the parts? Did you buy from Maule or find them elsewhere?

The bent flap handle is to better allow reaching the handle when at 0 degrees.
M4 and M5 have totally different flap mechanism than M6 MX7 M7 M8 M9 which all have a bent up flap handle from production.
Original M4 and M5 had 0 degrees, 15 and 35, and later ratchet is 0 20 and 40 degrees.
Higher degree angles have been estimated on some aircraft though linkage etc needs some finagling.

Can't imagine having to reach farther down for the flap handle. Moving the handle on my MX-7-180 in and out of the -7 degree setting is a long stretch even with the bent handle.
