- OK here it is. Quickie 500 is also known as RC Sport Pylon as descibed in
- my 1986-87 AMA Regulation Manual. I believe that Q500 falls under Class II
- or III. The AMA regulations for the aircraft is as follow:
-
- 1. Engine limit for Class II and III is .40. The motor must be front
- rotary induction, side exhaust, and a throttle that will permit it to
- idle low enough that the airplane does not roll on grass.
-
- 2. Stock or commercial mufflers are required. Muffler pressure is allowed.
- Tune pipes and pumps are not allowed.
-
- 3. The airplane must have a minimum of 500 sq. in. of wing area and a
- constant chord with a minimum thickness of 12% of the chord.
-
- 4. Fuselage is box type with minimum corner radiuses of 1/4 in.
-
- 5. Landing gear must be fixed with a minimum of two wheels.
-
- 6. Airplane weight not to exceed 10 pounds but 4-5 pounds is the norm.
-
-
- The flying course can be the course used by Formula I or Quarter Midget.
- Both courses have three pylons labeled 1,2, and 3. Pylon 2 and 3 are spaced
- 100 ft apart and pylon 1 is located 608 ft away from 2 and 3 for Formula 1
- and 475 ft for Quarter Midget. Minimum race lap distance is 1055 ft for
- Quarter Midget and 1320 ft for Formula I. I believe the race is for seven
- laps. Some of speeds I've heard ranges in the 150 to 170mph. I believe
- Formula I is in the 190 range. Someone ought to calculate the kinetic
- energy of one these birds and compare it to any ordinance or small round
- munitions. I think a surprise is in store!
-
- Hope this helps.
