As mentioned, I have the GTM oak skids on my BUSA 1/4 scale DR.1. They are scale reproductions and work absolutely wonderfully-without them, there would no doubt be problems! My DR.1 comes in so realistic and solid it is scary how real it seems. I come in with just a touch of power and touch down very softly on the mains and "continue to fly" the plane on the ground keeping it straight and smooth. Once the speed bleeds off (which isn't much BTW) the tail will softly drop onto the oak bungeed skid and proceed to do an ever so graceful semi ground loop to the right (more of a gradual curve) and the left wing skid does its job every time. It is such a real experience landing the DR.1 and that is why it is one of my favorite planes of all time! Even with the tall gear, I have never had a nose over and I think that is due to the scale bungeed landing gear system that I incorporated, plus, it allows the 15 pound model to touch down ever so gentle with no tendency to bounce.
