Mi è capitata questa chiacchierata su spinte e nu mero di pale che propongo senza voler entrare nel merito di quanto scritto.

9 blades will give more top speed but they dont have the same thrust at lower throttle like the 12 blades will. People are always quick to say how a 9 blade is more efficient but that isnt always true. Its more efficient at full throttle but if you are able to get better lower throttle performance with a 12 blade while moving the same amount of air that a 9 blade does at full then the 12 blade wins! If you are after constant full throttle efficiency the 9 blade will be good but if you want good all around performance the 12 blade is better. The FMS (Eflite branded in the Viper Jet) 12 blade w/36mm fan is a good combo and with a 6200 pack I can fly for over 6-8 mins with low lots of mixed throttle. The 9 blade inrunner that freewing makes will be good but won’t be as versitile. Also... you need to get into the ESC programming and drop timing to lower than it is out of the box. You will save 10-15 amps draw and a lot less heat too.
