This is really a great idea.
I have allways used the "kill before touchdown" method.
The reason was at first to reduce risk of injury. If you hit yourself (a sudden wind gusp etc.) the damage is a lot less without a rotating prop. Later I have used it to save props. At our field wind allways brings some sand on the paved runway. The less you run the engine the less abrasive it is to the prop.

Well, after reading this thread I reprogrammed my TX. Now I have a 3-pos switch in front for normal idle, 1800 1/min. Mid position is for low idle, 1300 1/min, and the last position kills the engine. It works like charm, it's almost like cheating, landing is so easy with improved braking. After landing the engine still runs, has never stopped during approach. If I want I can taxi it back, also I can add power if needed. The engine is OS 1.40RX .

I have Futaba 9 ZAP. I copied the normal condition, separated throttle trim for that, and voilá. I can trim idle for both conditions, other trims are combined.


Thanks, guys! It was worth reading this. You allways learn something.
