One more thing...

It is extremely important in R/C Combat to be consistant. This means several of the same plane with the same engines running the same props in each and all of them set up the same.

How many is "several"? About 3 is enough for a whole season of 6 or 7 contests, each featuring 5 or 6 rounds. If more rounds are flown in a single day, you might want to add more planes to your fleet. Now, this number is based on the fact that I absolutely despise making repairs between rounds - I don't even like to change props. If something happens to a plane, simply set it aside and grab another. Less stress and more fun that way.
