Hey DC,
Yep, those micro servos are fine, but they are at 9 grams. Now, you may like that, but the Guillows kits fly way better as light as possible.
If you're trying to save some cash, I would check out either the Waypoint servos at
www.aircraft-world.com or the Bluebirds at
www.parkflyermotors.com Those are only 6 grams each.
Geof.
