- 3300m Ah Li-Po (20C min) Beretta EDF Park Jet Advances in brushless motor & Li-Po battery technology have made a huge impact to the popularity of Electric Ducted Fan models. With batteries now capable of providing massive amounts of power for their diminutive size, & motors spinning faster than ever thought imaginable, there’s been no better time to enter the world of the electric jet. Although not aimed at the outright novice, Beretta’s low wing loading offers a wide & safe speed range that’s ideal for sport fl ying. Moreover, the more experienced fl yer can use a hotter powertrain, which will provide unlimited vertical acceleration & ‘seat of the pants’ performance. Constructed from tough EPP foam & utilising full span carbon wing tubes, Beretta should prove a little more robust than your average foamy, whilst its removable wings make it compact enough to fi t inside the smallest family hatchback... a true pocket rocket! Bags of wing area & large control surfaces make this model a real delight to fly. My simple take-off dolly is fabricated from 20mm plastic water pipe & leftover undercarriage assemblies. While a little larger than the average park jet, Beretta dismantles to fi t in a small hatchback.

Better Get Building! Hot Metal You can make ballast blocks by pouring molten lead into moulds carved into blocks of wood. The moulds need to be tapered so you can get the lead out again, but more importantly the wood should be as dry as possible: damp wood will make the lead spit back, & hot lead will cause serious burns. Be warned, then, & protect yourself with thick leather gloves & safety goggles at the very least. If you have any doubts about casting lead weights, you can make up blocks by cutting sheet lead into small pieces & gluing them together. If you need some lead sheet, try scrounging it from your friendly local roofi ng contractor. ...

- 2000m Ah Li-Po I’ve been flying R/C for over 30 years now, & whilst it’s good fun operating ‘full house’ models I still like to fl y 3-channel rudder / elevator occasionally. When pondering an own-design fl ying boat I decided that this, too, would be a rudder / elevator model, with old timer looks & powered by an electric motor spinning a 9” (or thereabouts) prop. The internet puts such a wealth of information at your fi ngertips, & it didn’t take too long to fi nd a free-flight model upon which to base my design. I used a picture of it as the wallpaper on my PC for continued inspiration, & set about designing the Wave using CAD. With the plan drawn & the prototype quickly built, I was keen to get to the water’s edge to see how she’d perform. I’d given Wave a wide, boat-shaped fuselage with a V-bottom words & photos » Ton Van Munsteren section before the step & a fl at ditto after the step, which hopefully pointed to easy taxiing & fuss-free take-offs. I’m glad to say that I was right; take-offs are as long as you like & as smooth as silk, & on only half power, too. Open the taps, & a full-power ROW only takes about five metres! Once airborne, the lack of ailerons doesn’t spoil the fun for Wave will lift her skirt & loop, roll, stall turn & do a (sort of) half Cuban 8

First Appeared in: RCM&E November 2009 Issue Name: Colomban Luciole Model type: Scale home-built Designed by: Peter Miller Wingspan: 60” Fuselage length: 431/4” Wing area: 348 sq. in. All-up weight: 64oz Wing 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 & 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 & 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 & a fuselage with ply sides, a ply bottom & a stringered turtle deck. However, the lightness of this construction, when coupled with the Briggs & 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 & 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 & realised that it would be possible. Article in November 2009 RCM&E

First Appeared in: RCM&E December 2009 Issue Name: Ultimate 20-300 Model type: 3D / sport aerobat Designed by: Dave Royds Wingspan: 39” (991mm) Fuselage length: 47” (1194mm) Wing area: 4.3sq. ft. (0.4 sq. m) All-up weight: 35

Such was the interest for his bespoke Pitts components, Gordon went into production & the Ultimate Aircraft Company was born. As his product line expanded the next logical step was to produce a complete airframe, & his diminutive 10-100 bipe hit the market. Following the success of the little home-built, Gordon returned his sights to the aerobatic scene & produced a series of high performance aircraft, culminating in the fl agship 300hp, Lycomingpowered muscle bipe
- the Ultimate. Despite the Ultimate gaining in popularity & 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 & go for a h&-launch. Gripping the top wing & 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 & pulling back on the elevator soon had the Ultimate climbing vertically
- gaining a little height & kicking the rudder & elevator over produces a very scale spin; adding a little opposite aileron levels the wings & reduces the rate of descent as she pulls into a controlled, fl at spin. Releasing the sticks & dipping the nose pulls her straight out without any over-rotation or control surface stall. Very nice. Although not designed as an out-&-out 3D machine, she’ll still handle the basic staple manoeuvres with relative ease. Prop-hanging & torque rolling requires very little in the way of corrective input, whilst walls, harriers & elevators are effortless with minimal signs of wing-rock. Knife-edge & 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 & 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 & vertical punch-out were defi nitely noticeable.

RC2075 Wittman Tailwind Plan by Peter Miller The Wittman Tailwind is probably the most famous aircraft youve never heard of. Steve Wittmans cheap home-build cross-country sportster kick-started the home build boom in the 1950s & its still being built & flown today. Peter Millers 48" span model reproduces the Tailwinds pleasing lines & flies superbly well using a. 20-.25 two-stroke or four-stroke equivalent engine. The huge fuselage means an electric conversion should be easy to engineer too. The new CNC/ Laser-cut parts set speeds up the build process by reproducing the ribs, formers & other parts (apart from strip balsa) required for the model while a wood completion pack that
