RE: Best setup for a Shock Flyer YAK54???
I agree the lightest setup possible is the way to go. I fly mine with the AXI 2204. The Eflite 300 is pretty much a clone of this motor and is slightly cheaper. The guys I fly with tend to like the 3 cell lipos over 2 cells but that is most likely just personal preference. Thunder Power batteries are my current favorite as they are a little lighter than the others available to me locally.
That Cyclone motor looks interesting, who carries these?
