SkySurfer The manual calls for 875mm blades, but that’s a 2 blade head. |

Notar Yes, thats what i fly, but its also turbine. When it came out Vario told us not to use the 4 or 5 blade head since the air from the tail causes a reaction for front and back bobbing. I also got rid of the idea that you need to run the Edf fast all the time to counter the torque, the Edf is a power pig on the nortar.So the slower you can run it, the longer you will fly. So I simply plug the Edf speed control into the Ikon 2 yaw channel and install a relay so everything works right on the transmitter.And the fan speed ramps up and down due to load conditions. And I got her flying for 10:30-11:00 minutes on 3 5000 6s packs. This was the exact Edf and motor combo for the big red one.As for the bobbling, I’ve never encountered it on the 2 520s and the md 900 that I’ve have, but there all electric . I will say the 520 and 900 are ridiculous with how tail heavy it is. I got 7 pounds in the nose just about to balance her out. If the weight distribution is off the heli will bobble. And when the rotator cone opens and closes it can blow the air down raising the tail, witch could cause a bobble. I found it best to leave the cone full open and vary the fan speed. The cone is on a pot on my transmitter, so I can play with it, if need be. Make sure it’s a active freewheeling esc for the EdF.  |
