Hi,

I'm new to F1D models.

I have 2 F1D's now, one 1.2 grams and one 1.3 grams.

I already have flown with them. But I have a problem. I have used
rubber (tan II 07/99) of 1.6 grams/meter and I had many turns left on
the rubber. I think 1.3 g/m is a normal valuae for this type of
models, isn't it?

Do I need to lower the pitch? It is now 650 mm but I formed the
blades on an 750-800 mm propblock so the tippitch is to high. Maby I
need to try 550 mm so the avarage pitch will be around 650 mm.

I also would like to know how many turns I can get on a motor of 0.6
grams. For example for motors of 1.2, 1.3, 1.4, 1.5 and 1.6 g/m.

How many turns do I need to have at the end of the flight? I know
with a F1M model it's about 10% of the start turns.

I hope someone can help.
