Not the only fuselage, but Eagle Mk. I’s whole airframe is finished now. And as there is still some balsa wood and time remains, I chose to build a second glider. It would be a great addition to have Eagle’s younger brother in the hangar. Hearn’s Hobbies has produced a couple of nice kits. Two of them for those who would like to build a larger sailplane: Eagle Mk.I and Eagle Mk. II. The latter could even be easily converted to the gas-powered model with the tricycle landing gear.
Eagle Mk. II is another sailplane kitted by Hearn’s Hobbies. The construction itself has developed from prewar to the simplified early 50’s style. The fuselage is now of square shape, simpler, easier to build, lacks typical nose formers, and rounded bodywork. Airfoil is unknown, type of “straight bottom edged”, relatively thick and similar to the Clarks airfoil family.
Although “Eagle Mk. I” is designed for free flight, Mk. II could easily be converted for radio control. The plan offers both versions to be built. A spacious detachable cabin speaks for the RC version as there is plenty of room to install almost “anything” in the nose to balance the model perfectly.
I have started to build this glider with the fuselage. It is of a “traditional” truss-type construction with two halves and horizontal web members. The cabin is detachable allows access to the radio control components and ballast box in the nose. The tailplane will be detachable as well for better transportation purposes. I plan to build the free flight tailplane version which fits the back of the fuselage slot tightly and will be secured with a rubber band.
We’ll take a look at the tailplane and fin in the next article. Happy building 🙂
