RE: Hacker A20-20L Out runner
It works really well on the Fliton Mini Extra 330, it's a little underpowered for the Fliton Inspire Mini which is what I'm running it on now, but I like the flight characteristics of the inspire a little better and I think the Inspire is a better design (building wise) than the Extra because of the detatchable wings, the extra looks better IMO.
