I have one, flying with 400w on a 3S. It is ballistic, giving the club stryker a run for it's money.
unless you fly off concrete, ditch the retracts. not worth it, and just do not work on grass. not worth the weight penalty, and bendy wire legs just cause it to flip over.
Hand launches easy, and belly lands real easy. (ditch the missiles too).
No need at all for rudder (with no retracts), leave the weight off.
Great flying plane, but a little pricey for foam (compared with GWS), but i am in New Zealand, so we have greater freight costs.
