The model comes with our new MPS-2A twin-motor system. Our preferred batteries are either a 2 or 3-cell 700 mah Li-poly pack. Better plan on an ESC capable of at least about 3 amps max, and once again our personal favorite of the ones we've tested is the CC Pixie 7-P. We recommend 2 or 3 of the 6-gram servos such as the HS-50 or GWS "Pico".

Performance with the 2-cell pack is quite spirited, and flight times are something well in excess of 35 minutes (I had to cut the test short at that time because they were closing the facility, but there was still quite a bit left in the batteries at that point). However, the plane really shines with a 3-cell 700 mah Li-poly pack. The model will just about hover at full throttle, although we caution you to keep the throttle at or below about 3/4 except for occasional burst of 5-10 seconds max, to avoid overheating the motors. At full throttle those two little N-20 motors are reading a total of about 29 watts on my Astro Wattmeter. That equates to about 93 watts per pound, a humongous number for a backyard/park flyer. Don't worry, there's almost never any need to use that much power. The 3-cell 700 mah pack has been clocked at 48+ minutes of normal cruising flight in this airplane, and the 3-cell Ryan will loop from level flight at 40-50% throttle. With the separate rudder it does beautiful knife edge flight, some really tricky zero-bank turns, and can do rolling circles. Forward slips on final approach are also a lot of fun and quite effective for getting into a tight landing area. It's one of my favorites for sport flying in my back yard, at the park or at the local R/C field.
