To help we need some specifics of your flights and the model you use

Are you getting to the top of the site?
Do you use up all of the turns?
If not how many turns are left?
What is your average rpm?
What is your cruising rpm?
What batch and size is your rubber?
What is your prop pitch and diameter?
What does your plane weigh?

You should be able to get more turns and torque out of the motors, as Tim said 9.5" of even lesser batches motor should give up to 50% or more turns than you stated, and .45 to 5 in oz of torque should be attainable. Even supersport should take more turns unless you are using a large cross section motor. Any motor with a broken in length of less than 9" is pretty large cross section and if you need motors that big you might have to make some changes to your prop and or model trim.

  Hello

  I have some problems with F1d and I will apreciate some
  advice...

  Flying in a CAT III (25 meters; 82 feet) with good air best times are
  arround 18 minutes and very few times on 20 minutes.

  Whay I whant is to improve times, Im far from the times you guys are
  doing. But where to start? Im not sure if is a problem of a "draggy
  model" or I'm geting a bad prop/rubber combination.

  I have seen some post where the turst for a level flight was computed.
  How was done that? It will be very nice to find how much trust my
  model need for a level flight.

  Usually I load 1000/1100 turns and 0,28/0,29 oz-in. It seems
  impossible for me to reach values like 1500 turns 0,37 oz-in some of
  you are handling. DO I have to break-in more harder the rubber?

  Well, apreciate any recomendations and please forgive me if im
  repeating questions already replyed.

  Tnx, Ignacio.
