Quote from Pattern Student "I have the Aresti 40 with a Rossi 53 (two stroke), APC 11x5 prop. WAY too fast for pattern (more like the older ballistic pattern planes), out of sight vertical."

The speed of this or any other model is controlled by the throttle by the pilot. There is no reason to fly this at full throttle unless in an upline with options where the plane will slow. While the plane is capable of flying at the ballistic speeds of early pattern models the actual design is modern. Learning throttle control so the sequence is flown at a constant speed is desirable for time to think and a better looking maneuver. Many pilots use the throttle as an on/off switch. Down lines will be improved with the correct propeller acting as an air brake (large disc) on the front of the plane.

For additional information see the Pattern, Classic Pattern, IMAC, Don Szczur, Chip Hyde, Mike McConnville and related forums. I occasionally fly with Don (2003 nats pattern winner) and his sequences are flown at an amazingly constant speed. Read the judging rules for Pattern and IMAC www.mini-iac.com which includes judging criteria.

Hope this helps!
