Bugly Ugger is a fun fly designed by Mike Lee and built from a RCM&E plan. It has an OS 40LA 'blue' engine which runs flawlessly on 20% helimix (because that is the only fuel I keep these days) and OS#3 plug. It is a very quick and simple build and mine has a lot of hours in the air. Often comes out in the summer later in the day when I have had enough of bigger, expensive more unforgiving models and just want low effort, low brain power messing around. I wonder how many of these were built? There was a discussion in www.modelflying.co.uk.
The wing construction is straightforward since all the ribs are identical and symmetrical. I cut two templates and then all the hard balsa rectangles, stacked them together drilled two guide holes with the pillar drill and threaded them on to a dowel. The whole stack can then be shaped and sanded as one piece ensuring identical ribs. Somehow there were no photos taken though.
The horizontal tailplane and elevator and rudder is similarly simple as shown above. with the vertical tail has a few lightening holes ans is slotted into the fuz.
The fuz is basically a box so simple to assemble from relatively thick but soft balsa sheet. The top winglet is designed to improve knife edge flight.
The wing is held on with traditional wing bands using a couple of dowels drilled through the fuz (best drilled through both sides before assembly to ensure accuracy).
Because the structure turned out well the covering was done with polyester semi transparent Oracover film.
Buggly is clearly a fun fly and flies like a fun fly. Not accurate but lots of fun to throw about. Knife edge loops are possible although it does pitch towards the canopy (if it had one) quite strongly requiring down elevator. It is best in calmish conditions as are all slow fliers with such a big thick wing section. In a light breeze it will just sit stationary in a harrier... best a few feet off the ground... With tight coordinated turns it flies very tight figure 8 circuits inside the width of our strip.
