Inhoudsopgave van July 2022 - RCM&E

TOP LETTER For his letter this month Terry Anderson wins a very popular LiPo and low self-discharge receiver pack combo courtesy of Overlander Batteries - www.overlander.co.uk TERRY’S HINGING TIP Sometimes when hinging, even after marking the centre lines and carefully going in with a blade, I still managed to get a slight misalignment when hinging my control surfaces. This is more noticeable on smaller models. So, I thought about it and came up with this simple and fool proof idea... As an example, we’ll hinge a 1/4” tailplane and elevator, either built up or made from sheet. Find a small piece of ply, half the tailplane thickness, 1/8” in this case, and say about an inch or two long (I have also used a couple of steel rulers on top…

The Covid hiatus has given lots of us the opportunity to try something new. One of my personal projects was to design and build my own electric flight flying wing, inspired by my review of the Vogel-Fly Batwing in the July 2020 issue. Design criteria were a good sports aerobatic performance, a relatively cheap power train and a two-piece sub-1m wingspan to make transport easier. After six months of flying the original I’m very pleased with how it turned out. BUILDING Hi8us is built mainly from medium balsa with a little bit of ply and carbon fibre in strategic locations. The design evolved as I was building the prototype so some of the photos might not show the final solution, but they do show the general arrangements. FUSELAGE A building…

The daylight is longer and stronger. Temperatures are rising and the cruel winds of April give way to the gentle zephyrs of summer. Complex Winter Projects have at last reached their zenith. There is no more reason for delay. Traditional radio modellers emerge from their sheds blinking into the light. Their hearts, a mixture of trepidation and hope. Brand new models, with freshly hardened paint, are appearing at the flying fields for their maiden flights. Brand new radios are being programmed. Brand new engines are being run in. Brand new ESCs are being fried by inexperienced operators. The RCM&E Going Places diary is bulging like an Oil Executive’s wallet. ’Tis time for the outdoor season. TOO LATE WAS THE CRY However, there is another slant on this early season. Those…

PARTINGSHOT The subject of these cheerfully sunny flying pics, taken by Chris Williams, is Trevor Hewson’s ‘Panther’ autogyro. This elegant rotorcraft was built in 2013 from the Richard Harris plan (RC2114), published in RCM&E in April of that year. Richard designed the Panther as an autogyro trainer and Trevor confirms that it is, indeed, very stable. However, despite the jazzy colour scheme on the blades and underside of the fuselage his Panther does bear a few scars from disorientation-induced contact with a gorse bush but continues to perform very well. The 46” rotor diameter model is powered by an E-Power BL2820/07 919kV motor from a 3S 3000 mAh LiPo. The propeller is an APC 12 x 6E. Panther short kits are available from Sarik Hobbies: https://www.sarikhobbies.com/product/rc2114-panther-complete-set/ Photo: Chris…

BMFA CENTENARY EXHIBITION From July 18th to August 31st, 2022, visitors to the BMFA’s National Centre at Buckminster in Leicestershire (NG33 5RW) will be able to view the largest gathering of UK model aircraft, from the historic to the ultra-modern, that they are ever likely to witness. The exhibition is a flagship event of the BMFA’s centenary celebrations. The exhibition traces the fascinating progress of model flying from compressed air and rubber-powered models flown at the time Bleriot crossed the Channel to today’s gas turbine models and multi-rotor drones. Visitors will see original models by pioneers of the aviation industry like Sir Richard Fairey, whose Great West Aerodrome was a centre for pre-War model flying and is now London’s Heathrow Airport. Then there are World Championship winners, like Peter Watson’s…

Do you have a question to ask about any aspect of R/C aeromodelling? If so, send it in and we will do our best to answer it. If not, then we are sure that someone amongst our many thousands of readers will be able to help. This time we are repeating last month’s question from Alan Shaw, who wants to know more about closed loop control systems, as we didn’t have space last time to publish answers we received from two knowledgeable F3A aerobatic pilots, Peter Jenkins and Ashley Hoyland. Q I have noticed on many model aircraft designs that just the rudder is actuated by a closed-loop cable system. The only reason that I’ve been able to obtain for this is that it eliminates any backlash, but that would…

An icy morning in North Wales. Rosyfingered dawn was pressing long shadows down the garden. I was half asleep loading Fat Albert and forgot to pack any soft drinks. This omission would irritate me later. At least I remembered my camera and notebook. About three hours on I was the other side of The Pennines, via the low-level Derby route. Amazingly, I managed to arrive on time. BRING & BUY BMFA Buckminster was awash with happy pensioners. They were revelling in the Spring Bring & Buy. Indeed, there was overspill on to the gravel yard as happy punters sought out an unlikely bargain. Incredibly, I gritted my teeth, and ignored the joys of the swap meet. Unusually for me–like walking past an uncorked wine bottle–I stared ahead, zombified and aloof.…

KIWI SE5A Last time in Pilots’ Pictorial we squeezed in a picture of Neil Marfell’s 72” span SE5a that he built from Duncan Hutson’s design of the famous WW1 scout. And we do mean squeezed in - the picture was a bit on the small side and didn’t really do this fine model justice. So, here’s Neil’s model again, at a slightly larger size so that you can appreciate it more fully. Powered by a Laser 155, Neil added a tail wheel for easy taxing and used closed loop systems for the elevator and rudder. It is fitted with Futaba servos and flies using Hitec A9 radio. WRONSKI’S RAINBOW This fine-looking Republic Rainbow is just one of several impressive multi engined models that Brian Wronski has built recently. The sandy…

MUSTANG P-51B With Ton van Munsteren’s P-51D flying just great, and with him also being a big fan of the Razorback version, it was easy for him to select the P-51B as a follow up warbird project. The wingspan is the same as his D version, at 1140mm, largely because it suits popular 3S 2200 mAh LiPo packs and this size of model is nice to handle. It’s easy to hand launch and with a small push the P51-B will fly away very nicely without using too much power. HOLLAND FOURNIER In his latest ‘Model Magic’ scale walkaround Alex Whittaker looks at a mighty Fournier RF4 owned by noted show pilot, large scale modeller and ex-BBC cameraman Steve Holland. Steve scratch built his impressive Fournier to 1/2.5 scale. She spans…
