Jim,

Chuck is right about the JR system, I fly with that system also. I have a book on CL scale and electronic controls if you are interested (send me a message thru RC universe). In terms of options sport scale requires the following.

1) takeoff
2) 10 level laps
3) Option 1
4) Option 2
5) Option 3
6) Option 4
7) Option 5
8) Option 6
9) Realism (judge thru the whole flight)
10) landing

Sport scale allows touch and go and Taxi to be counted as two options
Throttle counts as an option
Flaps are an easy great option, hard to screw up
30 degree high flight is an easy one

It is up to the pilot to determine what 6 options they will pick, based upon the aircraft they are flying. But remember if you try to perform a outside loop with a DC-3 in scale competition some judges may give you a hard time because the real DC-3 did not typically perform an outside loop. Bottom line look for things that move in flight on the aircraft you are modelling. For example the P-51 mustang you can pick from the following: retractable gear, open and close radiator scoop door, flaps, move canopy, you get the idea.

Don't build a CL scale model unless you are going to install throttle control, either 3-line or electronic controls. It is hard to score well in competition without throttle control. Here is an suggestion for a piper Cub or any model with throttle control only

Takeoff
10 level laps

throttle control
Touch
Go
30 degree high flight or Flaps if you have them
Taxi (part 1)
Taxi (part 2)

Realism
Landing

Hope this helps,
