I'm just waiting on Paypal to do it's magic so I can get my kit in the door.
Power setup will be...
Mega 22/30/2
MEC Superbox, 5:1 ratio
Castle Creations 60 amp controller
20 Sanyo 2600's
APC-E 16/10

This gives me a 68mph pitch speed, and almost 9lbs of static thrust. I plan to lighten the kit as much as possible during construction. If I can shave 1/2 a pound off the AUW I should have no problems coming in at 8lbs or under with everything. Of course the use of lightweight mini MG servo's will help things also.
Duration should be good as I won't need full power except for take-offs, and anytime I want to do big loops or vertical pulls. More or less I like low slow fly-by's with a little wing wagging.
The best thing is the total power system GB/Mega/ CC 60 amp ESC costs only $272. Isn't bad considering a OS .91 4-stroke will run $250. I suspect this combo would fly any of the Skyshark kits. Even the Avenger at 13lbs with it's huge wing wouldn't be a problem.
I chose the Stuka because I like them (duh! lol) and because it saves me booko deneiro because I don't have to buy any retracts, and it's still scale.
