learntolandshort/Usernameguy hits a home run with this one.

If I don't add a fair amount of power on the descent, my sink rate gets really high and the flare doesn't arrest it. I've done some terrifying bounces playing around with lower power settings and slow approach speed with full flaps. I can grease it on with more speed and a bit of power on the approach and just 40 degrees of flaps rather than the full 48 degrees. As the video indicates, that configuration results in a lot of float time in ground effect, making pinpoint landings impossible. On a 1500 foot grass strip that configuration is fine, but it wouldn't work with an 800' strip. I can also make an acceptable short landing by hanging on the prop with a fair amount more power during a slow approach. With about 1500 - 1600 RPM, my sink rate drops down to a manageable 200 - 300 fpm. The problem with dragging it in with power is the pickle it would put me in if I ever lost the engine on short final while I still had trees under me. I'd love to go flying with another Maule driver that could demonstrate the proper balance of speed and power to accomplish a steep approach without hanging on the prop and without bouncing like a super ball.

THAT is a REALLY bad habit to get into.

My problem is that my plane has a vernier control on the throttle and pressing the detent and pulling all the way back doesn't cut the power. I need to press the detent, pull all the way back and then start unscrewing the thing,If I goose it before touching down to slow my descent, getting rid of that power isn't instantaneous.You are not GOOSING anything!! Just roll it to the right a few turns a little bit earlier than you are doing now, catch up to your plane, sounds like you might be just a little behind it?? You're just adding a couple hundred RPM's and when you touch down and come on hard with the brakes you can shed the power then.
Same question for M6RV6 - This weekend I will go play around at altitude as you recommended. The weather is supposed to be clear and cold and its been a couple of weeks since I got my wheels off the ground. Last week we had some clear weather, but the turf strip was soggy from all the melting snow, and the homeowner's association closed it.

MTV, I'm not sure I see what you see. I see his left hand go from the throttle to the flap handle?

I do have one question about the type of approach he is suggesting. Perhaps one of our super-high-time back country pilots can address this...
The stabilized approach on the back side of the drag curve looks like it works real well, however it seems to me that a good gust, downdraft, dust devil, etc. on final could easily stall a wing with very little warning, and a high chance of a wreck. It looks to me like you are operating in a higher risk position (little reserve energy) for a much longer period of time.
In calm morning air, it would seem that this is not a problem. But at any time the air was active from heat, wind, weather, etc. it sure seems to me that flying around close to the terrain, in a higher risk configuration, would bite someone sooner than later.
How do the highly experienced bush pilots reconcile this apparent risk?
