I'm not a great LPP flyer in Cat 4 but I would guess you would do best with something in the range of 2 1/4 to 2 1/2 grams of rubber in a motor that is 20" to 22" long. You will probably need to use sleeves at both ends of the motor. Your model should be able to handle a launch with something over .4 in-oz of torque. You may need to use less pitch to get sufficient climb but this will depend on your prop design and how much it flares.

Maybe others will chime in with more or different info.

  Subject: [Indoor_Construction] Hints for Cat IV LPP flying


  I have the opportunity to fly in Tustin in April, though I've never flown indoor before, other than coach Science Olympiad. I plan to enter LPP.

  I would appreciate any pointers on how to fly in a CAT IV site like Tustin. I now fly in a middle school gym where I can practice 30' no touch flights.

  For starters, I was wondering the approximate range of rubber size to use, especially to get to the ceiling. My prop is now set at 22" pitch. How does a 20" loop of .093" sound? Or does high ceiling flying require something like 24" of .080"? I plan on practicing using a 1/4 motor in the gym and later at Tustin to test.

  Thank you.
