I was flying at Ocitillo Wells off road park today. The elevation is about 200'. The Mac really likes having some air to breath. 25% less throttle is needed.
I have been weekending at Ocitillo Wells most of my life. We have video of my dad flying there in the late 60's. This is the first time for my 90 Mac with expansion chambers. All I can say is WOW!!!!!
El Mirage is almost 3,000' and where most of my flying has been done. 200' msl is a big diference. The rotors have alot more lift. Takeoff speed and power are considerably less, I got ballanced on the mains and it lifted off before power was added:rapture:
I started flying there with a 72. A couple years latter with a 90. Now with the expansion chambers. It is kind of like driving a nascar cup car on the city streets. A lot more power than you really need, but man it is FUN!!!
There was a fixed wing ultralight there today. He liked to fly at about 20 mph. It was hard to fly that slow, but I remembered low and slow(behind the power curve)flying at El Mirage and it worked great. Fly as slow as you want at altitude.
A nice side effect of having all the extra air is that it burns less fuel. I thought it would burn more, I am flying the same but with less throttle. Flying along just fast enough to maintain speed and altitude at about 1/4 throttle. The Excess of power is intoxicating. I am going to have to be careful to find the limits of what is capible with all this air.
