I had the opportunity to experience the Desert Aircraft DA150 power first hand last weekend. Steve Milos was generous enough to let me fly his new Godfrey 37% Extra 300L/DA 150. Steve flies mode 1, I'm mode 2. No problem, just connect our Futaba 9Z's and data transfer his model to my Tx. Reassign the sticks and trims and off we go. One word of caution, always go to the trim screen and look at the trim setting. Reassigning the sticks and trims only changes the functions, not the settings. I didn't do this.
I should have known something wasn't right on start up as the idle was very high and I needed to trim it down several "clicks" (beeps actually). The DA150 is very docile as far as starting and idling go. It was running rich, but didn't seem to be a problem. As I accelerated down the runway the plane leapt into a vertical climb at half throttle. I pushed forward on the elevator stick and could only maintain a vertical climb as I frantically beeped in down trim. The transfer from a mode 1 to a mode 2 Tx left Steve's throttle trim setting on my elevator. At this point Steve was probably having second thoughts about me flying his new plane! Lucky for me the DA150 will pull this plane straight up at half throttle in a easily managed vertical climb.
The engine can only be described with over used adjectives like awesome. This combo is such an advantage it is almost unfair in an Unkown sequence. There is ample power to fly relatively slowly, discuss the next maneuver with your caller and smoothly throttle up into any maneuver imaginable. I only used full throttle a couple of times on verticals, such as after a snap. The plane accelerates like stink and the bolly 30 x 12 will make your ears bleed. I don't know for sure, but I think Steve's plane is between 35 and 37 lb.
The throttle response is also unreal. It is absolutely linear, one click on the stick and a corresponding change in power immediately occurs. If I sound impressed, it is because I am. This thing was so much fun I almost wet my pants (not really).
Funny how our perspectives change. A few years ago an 80" Midwest plane seemed huge to me. Now my 102" Ohio Extra 300L seems small.
