She still needs to be fitted out with mast and smoke stack, but we went ahead with a short harbor cruise to test her seaworthiness.

I finished this model in mid- December but I haven't had the occasion to snap any pics until today. Its pretty typical but has a few twists.

It is a 30" scaled-up version of the Micro Moth by chris3d. This is my third build of this model, the first in the original size, the second enlarged to 26" span. Both of those models were fantastic fliers, and I hope this one performs similarly.

The airframe is built entirely of 3mm "C" foam from balsapr.com, using my usual creased airfoil construction, but without the CF tube spar I usually incorporate into the leading edge. The flying and landing wires are tensioned, and provide a very stiff rigging. The wire itself is braided silk fishing line stripped from from an old fishing reel, and has worked very well on my other models. They are anchored to the top wing cabanes which are bamboo skewers that pierce a bulkhead in the fuse, and the "tank" in the middle of the top wing; at the lower wing root is a protruding music wire link that runs across the bottom of the wing to carry the flying wire tension load through the fuselage.

The landing gear are CF tubes, sandwiched between several layers of foam to set the splay angle. This gear is decidedly non-scale but has a clean appearance and seems durable. If I dork this model on maiden that will be where I start the rebuild.

The outboard ailerons are driven by a single Pico servo via pull-pull cable connected to bellcranks which drive the...Continue Reading

This model is constructed of 2mm foam salvaged from a sheet of sturdy board that was headed for the trash. I was just about to fold it up and stuff it into a trash bag when I looked at the thin layer of foam sandwiched between 2 paper layers, so I peeled a corner back to test how cleanly it would come off, and to my surprise it came off cleanly without leaving any residue or paper behind.

This foam has a porous surface and is stiff along one axis, flexible in the other. it feels like a lower density than depron and can be creased without snapping, too. regular CA melts it, but foam safe works fine, as does polyurethane glue which expands into the porous skin and holds on tight.

It sat in my foam box for a few months till I needed a light thin foam for a small build, it was the perfect choice for a scaled-up old time sheet model, the Frog junior series featured sheet balsa construction and were designed to be stable and easy for a junior flyer to trim even at a scant 11" wingspan.

I scaled up the plans to 18.5" span and made a kit of parts, and before the night was through I had framed up the fuselage and hinged the tail feathers.

Another night to make the wings and install radio gear, and most of a Saturday afternoon pleasantly spent painting and detailing produced what you see here.

Full up flying weight is 76g including a 300mah 2 cell lipo.

It is motivated by a hobbycity.com 10g brushless motor and 6g esc spinning a GWS HD6030 prop, and...Continue Reading

I've never done this before so I'll try to keep it interesting.
