If they're having fun then they'll want to go again. . . Have we given up trying to save the hobby for the next generation or do we have to adapt to change to ensure its continuation? Are our flying clubs destined to deteriorate into fields of grumpy old men depleting slowly and recounting tales of how it used to be? As the BMFA struggle on with their free flight founded education programme I was asked if there was anything we can do, individually or as a club in R/C land, to encourage new youngsters in, or help keep the ones we already have.

So you've flown your latest ARTF or scratch-built pride and joy for the very first time. How did it go? A few beeps of up trim and a couple of left? A click of the needle valve, maybe? Job's a good 'un! Are you happy to leave it at that, or would you like to try and get the best from the model with a little tweak here and there? It's true that many of us are very happy to leave well alone after the first flight of our latest toy, never quite getting the time to explore its true flight characteristics with a view to optimising its aerodynamic trim. Having lectured on this subject at various club nights over the years I also know it to be true that even the term 'Aerodynamic Optimisation' is well over the heads of many club fliers - increasingly so in this ARTF age, as we lose the basic skills that 'old school' aeromodelling used to provide. You may think that such optimisation only really applies to aerobatic aircraft where ultimate precision is being sought, but this isn't the case.

TEST FLIGHTS CAN JUST AS EASILY BE PROBLEM-FREE AS THEY CAN DAUNTING AND DISASTROUS. ANDY ELLISON PROVIDES 10 TOP TIPS TO HELP ACHIEVE THE FORMER 1 Don’t overstep your mark. Every pilot knows his own ability and for a test flight to go well it’s important not to overstep this unless you’re absolutely sure that you can happily achieve the goal. It’s good to have a healthy level of caution, and perhaps a little apprehension, as this shows respect for the fact that test flying is not always straightforward.

A structured training programme is better for both the pupil and club. A good few years ago now, as the groundswell of the ARTF craze swept across my flying club (Tyldesley MFC), we had 36 novice fliers listed on our books out of a total membership of 76. This novice influx came thick and fast, and it was a job for our limited resource of instructors to keep pace with them as they slowly progressed through their training. The sheer numbers that we had to deal with became overwhelming and some trainees were impeded due to a lack of continuity from one instructor to the next.

Getting a slope model away means reaching a reasonable flying speed asap so throw it like it just spat in your face! So you fancy R/C model flying, but without a motor, soaring like the birds and pitting your aeromodelling wits against Mother Nature? It’s a fascinating branch of our wonderful hobby that many power fliers never experience. At its most basic level, R/C model gliding can be split into three distinct disciplines: Slope Soaring Thermal Soaring Dynamic Soaring All three types of soaring are quite different, yet inextricably linked. Slope soaring makes use of air rising upwards over inclined terrain, thermal soaring exploits columns of warm air rising through the surrounding cooler air, and dynamic soaring extracts energy from two adjacent air masses moving at different velocities. The latter is a specialised form of soaring requiring strengthened models flown by expert hands and as such is a topic outside the bounds of this article.

Talk about flaps in R/C aeromodelling circles and there’ll no doubt be a fair amount of puzzlement and head scratching as to their true function and application. There’s no doubt that flaps are becoming more common in the modelling sphere with the pushing of ARTF boundaries to include scale warbirds, bombers and jets. Model turbines are shoving airframes ever faster, and moulded composite technology is making gliders ever slicker. Surely, then, flaps are much more than just an inconvenience that we need to buy extra servos for? BIG BOYS Full-size aircraft design has always been something of a compromise.

There can be no denying that Expanded Poly Propylene (EPP) has completely transformed the slope soaring scene since it was introduced to the hobby by American Pat Bowman about twelve years ago. Gone now are the days when a week of repair work would follow a slight launch mishap, mid-air bump or heavy landing. The design, construction and finish of EPP models has developed along with the materials used to put them together and as the years have passed by, the quality, performance and styling has improved dramatically. So much so, in fact, its sometimes difficult to differentiate between a well-finished modern EPP slope racer and a fully moulded carbon thoroughbred, even when theyre sat on the deck alongside each other.

So this is how R/C aeromodelling is panning out these days is it? Plug and play? Bind and Fly? ARTF in the truest meaning of the acronym. It suits me. ‘Daniel-son’ and I had the Radian Pro up in the air an hour after opening the box and that includes the 30 minute drive to the flying field! Is it just another electric foamie toy or have Parkzone properly done some homework here? The Radian Pro upgrades the already popular original Radian with a four servo wing, a reduction in dihedral and with extra reinforcement to provide an overall more robust model than the first rudder/elevator version. Extra partial span wing spars and a new wing mounting system stiffen things up considerably centrally and deliver a 7-function model now designed to make full use of crow braking, camber changing flaps and full span aileron control if your transmitter has the ability to drive them.

This review was first published in 2006. A Luna II has since been released. Andy compared the Luna with the RCRCM Typhoon 'head to head' in his Oct 2010 On The Edge column. No area of moulded slope kit production is as hotly contested as the 2m sport model market.

I'll go out on a limb here and claim that just about anybody who is anybody in the current UK 3D aerobatic scene has cut their teeth on a Weston UK Cougar fun fly. Dubbed the 'hovering machine', the original Cougar has found itself a niche as the ab initio model of choice for the prop-hanging fraternity. Its avid control response coupled with the pokiest of lightweight Weston UK motors has placed it in a position at the top of the class that similar ARTF fun fly models can only hope to aspire to. This particular trait of the Cougar is not really by design, as the model was originally launched to take on the dominance of other designs in the Fun Fly competition scene of the mid-to-late ‘90s.
