- Page 2 Now onto the fun stuff… First, please ensure that nothing is missing from the Booby kit and that none of the contents have been damaged. If anything is missing or damaged please contact your place of purchase immediately to make arrangements for replacement parts to be supplied.
- Page 3 If you want your Booby to be compliant with EPP slope combat competition rules, you may need to trim the spar by about 25mm (1”) at the wingtips before gluing in place so that it is set back far enough from the wing’s leading edge.
- Page 4 too heavy and that they are spread fairly evenly. Plastic shopping bags partly filled with sand make ideal weights. It may be easier if you remove the top portion of the wing beds by cutting along the leading edge. Leave overnight (or as per glue’s instructions) in this position while the glue fully cures.
- Page 5 RADIO EQUIPMENT INSTALLATION If you want your Booby to be compliant with EPP slope combat competition rules, you may need to position your battery pack and/or nose-weight further back than instructed. Please consult your local rules for specific requirements. Doing this will increase the all-up weight of the finished model a little due to the extra nose-weight required to balance correctly.
- Page 6 27. Using hot-melt glue (best), spray adhesive (sprayed into a puddle and then spread on) or 5 minute epoxy (not ideal), glue the base slice back into the bottom of the battery cut-out hole, creating a base for the battery recess.
- Page 7 34. Draw a line 5mm (3/16”) back from the edge of the spar slot in the middle of the central wing panel. Draw another line at right angles to this in the exact middle of the wing running a little way towards the trailing edge.
- Page 8 If two ballast boxes or two ballast tubes are installed they can be positioned at the Booby’s CG (140mm back from the noses) in the middle of each intermediary panel (between central wing panel and outer panel). A single ballast tube should also be able to fit into the leading edge of the central panel at the CG but would forfeit compliance with combat competition rules.
- Page 9 servos plug into your receiver’s aileron channel via the “Y” lead, with the servo on the other side of the wing requiring a servo extension lead (300mm). The mini size elevator servo is plugged into the elevator channel of your receiver. 46.
- Page 10 TAPING & COVERING These instructions are based on using 48mm/50mm (2”) wide strapping tape with fiberglass filaments, hereto referred to simply as “filament tape”. We recommend using the cross-weave variety throughout. However, for those of you wanting to keep weight to a minimum (sacrificing a little strength and durability), this can be replaced in many instances by the uni-directional (length- wise filaments) variety or even just 36mm (1 1/2”) wide filament tape (uni-directional filaments).
- Page 11 63. Now spray the entire top surface with 3M Super 77 (“multi-purpose”) spray adhesive and let dry for 5 minutes (or until aggressively tacky). 64. Apply cross-weave filament tape patches over the servos and receiver (if mounted flush with the top surface) to help hold them securely in place. 65.
- Page 12 79. It’s now time for covering. Spray the entire underside of the glider with spray adhesive and let dry for 5 minutes (or until aggressively tacky). 80. Bend over the ailerons and elevator and cover the hinge gap area using 48mm or 50mm (2”) wide coloured polypropylene covering tape.
- Page 13 88. Locate the two packs of Dubro E-Z Connectors included in the kit (you will have one connector spare). Install the Dubro E-Z connectors onto the control horns. Just use the re- useable nylon push-nut for now until its position on the control horn has been finalized. The second hole from the top is a good place to start.
- Page 14 102. First, double check that your glider is still balanced side to side. The Booby should balance in the middle of the central wing panel. If required, you can embed a small piece of lead into one of the wingtips towards the leading edge or remove/add lead from the lead weight already placed in the nose.
- Page 15 The correct amount of elevon and elevator movement for the Booby is determined by its balance point (a more forward balance point requires more control movement), the pilot’s skill level (beginners should have less control movement) and desired flight characteristics (less control surface movement offers more precise control over the glider while greater movement offers more responsiveness).
- Page 16 LAUNCHING TECHNIQUES The Booby is launched by hand. It can be a little awkward to launch effectively by yourself at first but becomes much easier with practice. If there’s plenty of lift and you can launch from the edge of the slope the simplest and easiest method is a side-arm launch holding onto one of the Booby’s...
