Where to pull full 48 degrees of flaps on final
Guy/gals,
I was wondering where, on your final approach, you guys are pulling your final 48 degrees of flaps. I pull at 40' to 80' AGL and landing assured. I have a MX7-180B and this question is for those that have 48 degrees to pull or have the knowledge and or experience to answer such a question.

Where I pull the last notch (48 degrees) of flaps depends on the approach. If there are obstacles around the strip, I pull the last notch before the final leg and adjust power to stabilize airspeed earlier in the descent to landing. On a tight approach around terrain that requires a short landing, you don't want to be fooling with lots of variables in the final leg.
Sight picture of the touchdown point and wind also affect the decision on when to use the final flap setting. If you're too high, you'll need the final notch earlier and a steeper descent. A headwind may require delaying the application of the last notch.
On a normal approach, I add the last notch just after my turn to final and stabilize the pitch and power changes.

I try to be very aware of speed as I pull flaps. (hard on your wing if you pull to fast) For the 48 d notch I make sure I am good and slow. Other than that I think you should practice pulling them at different positions in your approach.
To say you should always pull the last notch at X location in the approach would be wrong. Each approach is different, practice all types of approaches and configurations. That's what's fun.

I am also very conservative on airspeed and flap deployment, but aren't the Maule flaps also spring loaded? I don't think they necessarly give you the degree of deployment you've selected until the plane is below a certain airspeed.
Correct me is I'm wrong...
Personally I usually land with flaps at 24 gegrees. I do this so if I'm high I have flap in reserve, or if I'm low a little power will drag me in easier. Also it's a big advantage in the early stages of a go-around.
JMHO.

Yes the flaps are spring loaded But if you look at the push rods they are very tiny and I know we have bent a couple sets on ours even with the spring pack. In my 180 hp I rarely used the 48 degree but in the 235 I use it all the time.

It's not easy to lift the tail on taxi in a 180 engine Maule since it's about 250 pounds unless you have a good headwind. You might be able to do it with a 235 engine and a bigger prop. Hard on your brakes, though.
The flap push rods aren't that big, so it's wise to apply full flaps at a low airspeed. That's 60 - 70 mph for me.
I use 24 degrees of flaps in a crosswind or strong headwind.

With my 180 I had a larger prop and was able to lift the tail with a little effort and it can be done, hard on brakes , yes a little but replacement brake pads are less than $100 so I use them.
Kit # 11 from Maule will put the 48*'s of flaps in.....

Kit is just the detent strap under the lower end of flap handle and if I remember right about $30-$40... Easy to put in as per SB which is available online at Maule's site. I agree with WUP, tail up in 180hp can be done with the longer prop, power, and some brakes until rolling pretty good.
