need to inform as to what engine rules u are going to use

Cody clown is usually flown on .015 lines .most flyers wont have .018 lines with 52 ft length

Cody, I STRONGLY suggest that you use the NCLRA Clown rules. While there are several variations, these are the most commonly used and are available easily on the 'net at the NCLRA website. The rules you have pointed to vary quite a bit from what's being flown elsewhere.

Advantages of a fuel shut-off? The pilot can control where the engine quits in order to get eh model to the pitman reliably and quicker. It has been found that the way to get the most laps is quicker pits, all else being constant.

Yes, the double elimination format is an interesting twist. But the rest of the rules are important. Bob asked about the .018" lines, and Walt about the use of shut-offs, and the NCLRA rules use 60' lines, not 52'6". At the speeds that a good Clown is flying, 52' lines are just too short for the rotational speed.

I also suggest that you make all of the elimination races 7-1/2 minutes rather than 15. A 15 minute race is really tough on the pilots, particularly if one of them is flying more than  one entry. Yes, perhaps the final race could be 15 minutes.

I really want to see your event happen. It's been a long time since that part of the country saw any CL racing action.

This is on 52" lines.

How many seconds per lap?
