Time for my favourite job of the
year - a look back at the magnificent models that have graced the opening
screen of modelflight over the last twelve months.
THIS MONTH'S COVER SUBJECT John has completed his Lancaster that was featured in some detail on last month's 'work in progress' page, and has sent these lovely evocative shots of the completed model. John's black and white digital montage (below right) which he has entitled 'The Final Pee' has tremendous atmosphere and really seems to capture something of the tension of the occasion when these big boys went off for a night's deadly work, don't you think? Click each thumbnail to get the full impact of these great pics! The model is the Priory Kits Lancaster; it has a 6-foot span and is designed for four 400 brushed motors. The kit is designed to be hand-launched, but John has modified it and fitted retracts - something which he says took a bit of doing, balancing strength with lightness. The finished weight of the model came out at 5 lbs 5-3/8 ozs (2.4 kg). "My son and I have started flying together in the last year or so. This is a great way to spend some time together enjoying a past time we both think is great. "The FourStar 40 (above) is a kit that my son Russ, 14, built over the course of last winter. He did an amazing job of building it. We hope to have it in the air this weekend at a fly-in. The weather man is predicting snow and wind for the weekend but it is still four days away and one thing about the weather in Alberta, it can change in 5 minutes.
We kick off this selection of pictures from the Constellation MFC website gallery with Terry Cosh's magnificent 1/4 scale model of an A1 Crawford (above) - a 1930's homebuilt aircraft. Powered by a 120 Magnum 4 Stroke. Terry's Father built this aircraft as a full size at 21 years old in 1930.
"A few months ago I sent some progress pics [work in progress, #95, April 2005] of my Aviomodelli Skymaster, above. Well, unfortunately this time I'm sending some pics of the result of its one and only flight. "A quick resumé of the story. The plane was finished by late August. Good weather saw three weekends of engine runs, taxi runs, etc., that revealed that the original wheels were not supporting the 8.5KG weight and were seriously slowing the plane down on our grass field. Note that the weight was 2 kilos over the manufacturers specification but I read other modellers had built to this weight apparently with no problems! A change to bigger wheels and a pitch change on the props seemed to have the desired effect but after four weekends speed was still lacking. A close cut of the grass on the Friday saw ideal conditions on the morning of the 24th September. Several taxi runs on the hard baked runway with the shortest grass it had seen in a long time and with the twin engines giving a lovely droning sound as they went in and out of synch I was convinced that it was time. "Starting
the roll out from as far south on the strip as I could get, I left it
as long as possible before pulling lightly back on the stick - takeoff,
but not for long. I believe that the speed was marginal at best though
the ease of the rotation might indicate otherwise; in any case, my climb
was certainly too steep and with hindsight I should have allowed a far
flatter climb at this weight off a grass strip. Whatever, the result at
about 2m altitude was a stalled left wing that caused the plane to cart
wheel on contact. The damage is reasonably bad with both booms severed
and the nose totally amputated and lots of other less catastrophic but
equally serious damage. So, lots learned (You can always have too much
weight but never enough power I think sums it up) and surprisingly my
motivation not too quenched."
Pete Masters has certainly been busy since last he was in touch, adding a variety of models to his fleet, as you see here. 1 and header picture. PSS version of the Hurricane Mk I 1939/40 version. 2. The X-wing - a foam wing with a brushless motor on the back. 'Rocket' comes to mind when air borne and very good when power off on the slope or cliff. 3. The Predator 500 with which Pete has fitted a 700 brushless motor with 14 volts up its wiring which makes it go very well. it has a 54- inch wing span. 4. Stan Yeo's new model called the Bedlam, a 60-inch wingspan high-wing version of the Mayhem. 5. A nice little gun ship - a birthday present for Pete from the lovely Maggs (modelflight pin-up of the year, see below) and the family.
Rupert
did not keep any records about this particular model, although he recalls
that the foreplane was of the "flying" variety and was hinged
at 25% chord. He writes, "This was a docile flyer, well within the
capabilities of the average Sunday flier." Attached is a picture of my electric Hangar 9 Funtana S on skis - over 800 watts power developed, 6 1/4 lbs AUW, flies terrifically! I had previously flown the plane with 2x8 cell NiCds @ 2400 mah resulting in a 87 watts/lb metric (50 watts/lb is sport performance, 100 is mild aerobatics). I subsequently upgraded the ESC to allow power bursts up to 70 amps (was previously limited to 40) and put in a 6000 mah 4S3P LiPo - which dropped the AUW by one pound while upping the watts/lb to 127 - a 150% improvement! We maidened
the newly fitted plane on Saturday (10th December). At full power it ski'd
forward, rotated quickly, then blasted out at a very steep> climb angle
in a shower of snow - spectacular! The plane now has the thrust/weight
of a fairly high performance park flier while possessing the handling
and tracking of a "big" plane - very satisfying.
Bud Carlson has done some good detective work and tracked down the beautiful little unspecified model that was shown on the November issue of modelflight. Bud brought the picture back from the 2005 NEAT (Northeast Electric Aircraft Technology) Fair but unfortunately he had no details then about this lovely model of an Albatros D-11.
Here (above) is another little beauty of Steven Stratt's that Bud captured at the NEAT Fair - this time his Dornier Zeppilin D.1 - for which plans and kits in several scale sizes are also available through the two links shown above. The 1/6 version has a wingspan of 78.6 inches and is suitable for a 40 Astro Cobalt motor (or .60 glow).
