I've got a good few EDF's now and i've got the Hobbyking HD-100 Vampire being shipped to me as i type this
I ordered the kit version so i can put in the CS 10 bladed fan unit with a 2200KV motor that i've got all ready and waiting.
The sound off these Change Sun fan units is amazing and the closest you will get to a turbine sound IMO
Hobbyking also does a PnP model as well with retracts fitted but as mine is going to be a hand launch version i didn't need that one,just wish i had a good landing strip to go ROG with.
