RE: FlyFly BAe Hawk 90mm EDF
The fuselage is essentially pre-assembled inside before gluing the two halves together. The ducted fan unit and pre-assembled exhaust tube fit like a glove inside the fuselage.
My Hawk is using the new Hitec [link=http://www.hitecrcd.com/servos/show?name=HS-5065MG]HS-5065MG[/link] Digital Programmable servos. This high-performance micro servo features Hitecs digital, programmable circut for incredible resolution, centering and holding torque. It also features metal gears, a top-ball bearing, and 31 ounces/inches of torque with a quick transit time of 0.11 sec at 6 volts.
