The assembled tail feathers. Cut out the parts (above left) and arrange them in order on a flat surface covered with plastic wrap. Apply glue to each joint— done! The wing center section (above right) is assembled a panel at a time. Note the wing shear webbing is glued together to form the correct dihedral. Ribs are placed at an angle to promote stronger, more rigid construction. Completed center section of the wing (below left). Each panel is built separately so that it
can be assembled on a flat surface, weighted down, and glue applied to each joint, resulting in a warp free wing panel. Center section sheeting fits like a glove. Wing tip, at left, is removable from the center section (below right). Wood dowels align the two while a dihedral brace adds strength. Two rare earth magnets, fore and aft, keep it in place. Jerry originally had some doubts about this but it works fine.
As you move along the steps building the fuselage you’ll be amazed how well things go together. Having the parts cut out accurate- ly really speeds up the process of putting this baby together. You can’t imagine the torture of cutting out parts we old timers had to go through when scratchbuilding and then expecting them to fit. Now we have the best of the best. All of the laser-cut parts are interlocking and self jigging.
Another nice thing about building from
the manual, instead of on plans, is the great, clear pictures provided in this manual, and the steps, allowing you to easily pick up where you left off, that is if you checked them off. After completing the fuselage, which went exceptionally well, I moved on to the tail followed by the wing. Building the tail feathers is a snap. I lo- cated all the parts on the sheet and placed
them on a flat surface covered with clear wrapping. After making sure they were in- terlocked and flat, I hit each joint with some thin CyA and … bam! It was done and on to sanding. This went really fast—totally un- believable. After letting the parts cure I placed them with the fuselage, ready for sanding. Building the wing is more involved with more parts, of course. That’s why I saved it
Motor box with Scorpion motor mounted (above left). Correct down thrust and right thrust is built in. The motor box, with motor, is designed to be removed by removing three bolts. Jerry painted his black. Should you decide to use the
40
Scorpion motor, the hole (above right) in the motor box firewall is too small. It must be made larger to clear the collar on the motor shaft. A simple round file will make short work of this.
