Such was the interest for his bespoke Pitts components, Gordon went into production and the Ultimate Aircraft Company was born. As his product line expanded the next logical step was to produce a complete airframe, and his diminutive 10-100 bipe hit the market. Following the success of the little home-built, Gordon returned his sights to the aerobatic scene and produced a series of high performance aircraft, culminating in the fl agship 300hp, Lycomingpowered muscle bipe - the Ultimate. Despite the Ultimate gaining in popularity and the order book fi lling up, the company hit diffi culties, forcing its doors to be closed less than a decade after it all began.WILD BLUE Although the day of the maiden dawned with a beautiful blue sky, previous days of torrential rain had turned the runway into a mud bath. Not wanting the risk a nose-over so early in the day, I decided to bite the bullet and go for a hand-launch. Gripping the top wing and with a gentle underarm push, the Ultimate eased skyward. After a few test circuits to adjust the trims, it was time to see what she could do. Throttling up into wind and pulling back on the elevator soon had the Ultimate climbing vertically - gaining a little height and kicking the rudder and elevator over produces a very scale spin; adding a little opposite aileron levels the wings and reduces the rate of descent as she pulls into a controlled, fl at spin. Releasing the sticks and dipping the nose pulls her straight out without any over-rotation or control surface stall. Very nice. Although not designed as an out-and-out 3D machine, she’ll still handle the basic staple manoeuvres with relative ease. Prop-hanging and torque rolling requires very little in the way of corrective input, whilst walls, harriers and elevators are effortless with minimal signs of wing-rock. Knife-edge and hesitation rolls require a few degrees of top rudder to keep the nose up at low speed, but as speed increases the large side area of the fuselage keeps it tracking on the straight and level. Slow speed manners are quite exemplary; inducing a stall merely slows her to a crawl followed by a gradual, controlled descent, needing only a blip of the throttle to return to fl ying speed. Subsequent to the initial fl ights with the Hacker 16M, substituting the motor for the Tornado 4240 defi nitely upped the Ultimate’s aerobatic performance; while she’s never going to be rocket ship, the difference in acceleration and vertical punch-out were defi nitely noticeable.

It was no use - I’d have to build a new ‘un, but what? The criteria had to be fairly simple. A model of 30 - 35” (760 - 890mm) span, powered by a 2s Li-Po of around 400mAh and a brushless outrunner. Three 5g servos on aileron, elevator and rudder, carbon bracing and pushrods, and weighing in the region of 5oz (140g). Not exactly rocket science in leccy model terms these days, but still very relevant for anyone who enjoys indoor aerobatic aircraft. Nothing really took my fancy commercially, with a long list of ‘been there, done that’ airframes, leaving me with little option but to put pen to paper. After a few pleasant evenings sketching ideas out on sheets of A4, I transferred the design via my scanner to Adobe Illustrator where I could scale it up or down, stretch it, squash it and fi nally redraw it accurately, incorporating the slots and tabs that would be needed to glue it all together. In this regard I have to take my hat off to the work of Tim Hart at the Foamy Factory, as I could fi nd no better way of jointing the fuselage than his slot-and-tab method.Up close and personal. Positioning for the hand catch. Absolutely de rigueur for indoor one-upmanship. Mind that prop though, it gives a healthy nip!

First Appeared in: RCM&E November 2009 Issue Name: Colomban Luciole Model type: Scale home-builtDesigned by: Peter MillerWingspan: 60”Fuselage length: 431/4”Wing area: 348 sq. in.All-up weight: 64ozWing loading: 261/2oz / sq. ft.Functions (servos): Rudder (1); elevator (1); throttle (1); aileron (2); flap (2)Rec’d engine. 18 -. 21 two-stroke, or possibly a good. 15 for flying in light winds. FAST AND FRUGALThe first thing that strikes you about the Luciole is the very high aspect ratio of the wing: with a span of 221/2ft but a chord of just 26in, the wing looks like a ruler. Most of the trailing edge is taken up with very large fl aps, but the wingspan means that the small ailerons out at the tips have plenty of leverage! Between them, the flaps and ailerons take up almost a third of the chord, but the tail does better still since it has all-fl ying surfaces. The construction of the MC30 would look very familiar to most model aircraft builders, with spars, foam ribs, leading edge sheeting, cap strips and a fuselage with ply sides, a ply bottom and a stringered turtle deck. However, the lightness of this construction, when coupled with the Briggs and Stratton 650cc OHV V-twin engine, allows the Luciole to cruise at 105mph while sipping just five litres of fuel every hour. With an endurance of five hours you can do some serious travelling in this aircraft. Richard suggested that I build a model of the Luciole but I took one look at the three views and said, “No thanks!” That wing just didn’t look suitable for the size of model that I’d build. A couple of evenings later, however, I made a few calculations and realised that it would be possible. Article in November 2009 RCM&E
