Kul att fler skaffar! =) Den va ju billigare än den nya.

Googla lite på kommentarer mellan gula 12an och röda 9an:
En som köpt röda 9-blade: "I'm flying the same batteries, at the same speed, for the same duration and coming down with more battery reserve. I notice no difference in speed or sound with the new fan."
"Don, the 9B is indeed more efficient than the 12B."
"The sound is nearly identical between the two."
"The 9 blade is more efficient so longer flight time and better lower end thrust so it gets off the ground better."
"I'm not sure about the top speed but you would definitely see longer flight time, you really can't go wrong with either one."
"I've had both and see no difference in flight character. Even the sound is the same to me. The 9 blade does get better gas mileage, though; the same duration flights use less battery with the red version."

Såå... vilken som funkar finfint! Nån sekund/minut hit eller dit spelar ju ingen roll. Jag hade haft en 12-bladig hemma om jag valt den från början. :-D
