I have a Freewing Vulcan 4S EDF and this time of year when the crabgrass is growing rapidly < even-though the runway is mowed at 1"every 3 days, I have trouble getting enough speed to take off. Yesterday I removed the EDF unit and the Blades and housing were coated with a layer of grass stain and debris. I cleaned them thoroughly and will try again Saturday with a new 4S 4200 battery.
I think the failure to get airborne was as much a fault of the dirty EDF as it was the grass???
Thanks for your response.
