Can you say a bit more about in what way it is bad? Is it simply not
able to hold the head speed, or are there other problems?

I already have the smallest that came with the kit (12T, I think). I
have found some smaller ones, but they have a smaller axle hole. I'll
see if I can drill them out accurately enough.

As much as I detest web forums, I have now read through the thread.
They seem to agree that the two most im****tant factors are a low head
speed and a gentle flying style. The best times are achieved with a
head speed so low that the machine barely flyable, and hovering into a
gentle headwind all the time. Flying like that is, of course, no fun,
but the knowledge gained from these experiments may help find a
setting that gains noticeable flight time while sacrificing only a
little performance.
I have my timer set at 7 minutes. After that time, I normally put 1500
to 1800mAh into the battery, depending on flying style.
I have now done an experiment where I hovered for 7 minutes at
somewhere around 10-12 degrees, still with the 12T. Surprisingly,
there was no noticeable wobble, even at that extremely low head speed.
I don't have a tach, so I don't know how low. The battery took 999mAh.
