some other questions as well :

- What exactly is a "gearbox"? What does it do?
- I'm not into the technical stuff, so I wonder about the difference between battery packs : whats the diff between 7 or 8 cell pack and what does the "mAh" mean? What does it take to get longer flights and can a change in battery pack give the plane more power? Also : I see my plane has a 6V motor, then why is that battery pack over 6V? Does it matter how much V the battery pack is?

I know these are stupid questions when you are into this, but I've got no idea about it all and it would be good to know at least a minimum about it.

thanks a lot
