Kang,
Thanks for the comparative data you provided below. It is a reminder that there can be several approaches that can produce essentially similar results. BUT, you have to know what you are doing & why to be a consistent top performer. Or, you could rely on luck!
What would be a typical length of a motor for WC flying or specifically kagan's & Richmond's if available?
Are they backing off primarily to avoid torque issues at launch or to avoid hitting the ceiling (or what ever the structure is at the top)?
Gary

In 2000 at the World Champioinship, Kagan used a 1.9 g motor, and Richmond used a 1.23 g motor. Kagan won by 6 seconds, so a heavier motor is definitely better :)


Richmond put in 2510 turns and backed off 100.


Kagan put in 2300 turns and backed of 170, 60 turns remaining.

I saw many models torque-ing around on launch with excessive down-thrust. I didn’t experience these problems, but I don’t think it was because my motor sticks were significantly stronger. I think that the large motor I was using allowed me to back-off much of the initial peak, reliving a lot of stress on the model (2300 turns in, 170 backed off, 60 left after flight).



See, everything and nothing makes sense !


John, Jim, please correct these figures if necessary.
