The Delta-V 15 69mm EDF is an ideal choice for ducted fan airplanes requiring 68-70mm diameter fan units such as the E-flite BAe Hawk 15 DF.
We have received some feedback expressing concerns about the Delta-V 15 rotor blades becoming stressed and weakening while tightening. E-flite is now shipping a stronger rotor with thicker blades and improved material with no change in fan performance.
Delta-V 15 69mm EDF shipped from Horizon Hobby after August 27, 2009 will have a small blue dot sticker on the bottom of the EDF box or on the back of the rotor header card near the bar code indicating it contains an updated rotor.
If you have concerns about your Delta-V 15 rotors that you either purchased separately or ones which were included with your Delta-V 15 69mm EDF, please call (877) 504-0233 toll free to speak with a Product Support technician to get a replacement rotor.
