Constructed in the typical Mountain Models style, the Hyper Bipe(above left), built by Jerry Smith, is easy to build and goes together nicely. The “Tab and Slot” style of building provides for a very straight and accurate airframe. Jerry’s Hyper
inch models down to a fine art, and this one is no exception. The original Schmaedig Stick design, flown with a replica Anderson .65 on ignition, was reduced and set up for indoor electric R/C. The reduced Stick spans 38 inches and tips the scales at a scant 7.4 ounces. The model is powered with an E-flite Park 250 Outrunner with a Castle Thunder- bird 6A ESC and a GWS 6–3 propeller and an 800 mAh 2S battery. Guidance is provid- ed by a pair of E-flite S-60 servos and a Spek- trum AR6115 Rx. And to top it all off, Bob constructed the model the old fashioned way using hand cut parts. Meanwhile, have you ever found yourself
Bipe is finished in Solarfilm (above right) with hand cut trim; and each of the checkerboard segments was cut and applied by hand, one at a time. Now that’s what Pat calls, “Modeling”.
in one of those awkward positions where the engine quits at the most inopportune time? Or worse, the prop comes off in mid-flight. I’ve been there too, and there’s really not much in R/C flying that can be a whole lot more exciting ... but, to get a picture of the event is even better! Len Rozamus sent over the photo of his friend’s Multiplex Fun Cub doing just that. This is definitely one of those one-in-a-million shots, and fortunately, the dead stick landing was completely successful. Then into the scale realm we have Jerry Smith’s 35.4–inch span Hyper Bipe built from the Mountain Model’s kit. The kit was laser cut, and in the typical MM fashion, the
model went together beautifully. Power is provided by an Extreme Flight R/C Torque 1035 KV outrunner with a 30A ESC and an APC 10–4.5 prop with a 3S 1300 mAh bat- tery. Four sub-micro servos take care of guidance for the 4-channel system. The model is covered with Solarfilm with hand- cut trim, and flies at 26 ounces weight. For more information on the build look for the review article in the May 2012 issue of R/C Sport Flyer magazine. In the meantime, Bill Hannan checked
in with the following comment regarding Walt Mooney’s method of tightening bi- plane rigging. “… for some of my scale models, it was tightened by judicious ap- plication of heat from a tiny soldering iron held near the monofilament. This seems much less risky than the late Walt Mooney’s approach mentioned by David Wagner. For flying models, my preference is silk sewing-thread, which may be tight- ened with water. Although the dark-gray rigging employed on my fading red Farman Moustique does not show much contrast, it remains taut now, even though the model was proxy-flown at Woodvale, in England during 1978!” Next up is the 40-inch span Aeronca C-3

Gary Heard built his Aeronca C-3 (above) from the Dumas kit and was really happy to have the kit supplied Fuselage Building Jig handy to simplify framing the otherwise very complex structure. Bill Hannan prefers silk sewing thread to rig his flying models (below left), but uses the heat from a small soldering iron to shrink monofilament line on the rest, far less risky than holding the model over a hot stove as the late Walt Mooney has done. Though a bit on the hefty side to be a competitive flyer, Frank Womack’s 1/2A Texaco Fleetster (below right) makes for a terrific sport model for those calm quiet evenings at the field.

built by Gary Heard. The model was built straight from the box using the recom- mended equipment for power and guidance. A building jig is provided in the kit to great- ly simplify, and to take all the pain out of building what can accurately be described as a very complex fuselage structure. There’s not a right angle in it anywhere, so without the jig, building the frame would be nearly impossible. And last but not least we have Frank
Womack’s 1⁄2A Texaco Fleetster. The model finished at 14 ounces, covered with silk and dope, and set up for 3-channel R/C. Frank describes the model as “not really competi- tive, but a nice sport flyer”. Well, it looks like we’ve run the gamut
again with a nice variety of models and modeling ideas. With a little wet fuel, R/C and freeflight there’s enough here to prove that modeling truly is alive and well using both modern and old school techniques. And with that, I’d like to offer a heartfelt “Thank You” to all who took the time to send stuff over, and would once again say to all to drop a line and show us what you’re up to.
