[rcsoaringdigest] The New RC Soaring Digest | May, 2022 | Vol. 37, No. 5

The outstanding photo is by multi-RCSD-contributor Raymond Esveldt. Unfortunately, the details of the photo are lost to history, according to Raymond, with "taken during an aerotow event a few years back in the Netherlands" being his comment. Regardless, thanks to Raymond to permit this beautiful photo to be used for the May, 2022 cover.

In The Air RC soaring is not a crime. Terence C. Gannon Apr 23 · 9 min read "There's a Costco big box store not too far from where I live which stands just east of a great slope that runs due north and south for about two or three city blocks. The crest of the slope runs parallel to a road which is home to mostly light industrial tenants and low volume retail, so most times in the evening the street is empty..." Letters to the Editor There's lots in the mailbag this month, some of which is really 'meta'. The NEW RC Soaring Digest Staff Apr 30 · 5 min read "Can you tell me if anything been written for programming the NX-series or other transmitters for sailplanes for someone with our (admittedly low) level of expertise? What I am hoping to find is some kind of guidance, hopefully in your publication, that would not only show the 'how-to' but also the 'why' for the programming..." An Epic Maiden Have you ever been crazily obsessed with a new airplane? I have. Mike Poser Apr 28 · 10 min read "Meet Twister, a Euro-built three-metre 'moldie'—a slope glider molded from carbon composite. I think they named it Twisterbecause of how fast your head has to spin to keep up with it. After its sheer size, what is most striking about this soaring beauty is its immaculately clean design. All elements support the designer's mission to minimize drag..." Orcrist | A 2.5m VTPR Glider Part II: Building, cutting and skinning the tail and wings. Marc Panton Apr 28 · 17 min read "The vertical stabiliser itself is pretty mundane: a plank of hard/stiff balsa cut and butt jointed to align the grain along some of the stress lines, with an infill to make it triangular/normal tail shaped. A vertical spruce post makes up the final part giving the future rudder something hard to be hinged from and adding a little stiffness to the whole ensemble..." Our brand new Retro Logo Beanie is perfect for those chilly days on the slope. It features a beautifully stitched logo reminiscent of the original RCSD logo created by Jim Gray in 1984 and updated by Bunny and Bill Kuhlman in 2021. Check them out in the RCSD Shop.   Sponsored Red Petrel Redux Part I: Variations on a Theme Chris Williams Apr 28 · 3 min read "I have been a victim of Petrel fascination for more years than I can possibly remember—see Resourcesbelow for my previous article on the subject. When I was a strapping, virile young stud, I used to make 'em to a fairly large size, but time and gravity are taking their toll, and the Petrels coming out of my workshop are now more OAP-friendly..." Trimming Model Aircraft A short primer for beginners. Peter Scott Apr 29 · 10 min read "We wouldn't drive a car that drifted across the centre of the road. We wouldn't ride a bike at speed that had a warped wheel. We shouldn't fly our models that are not trimmed correctly. What does trimming mean? It means adjusting various settings on a model until it flies straight-and-level (SL) under cruise throttle or level gliding flight..." How to Create Great RC Soaring Videos Make yours stand out from the crowd. Raymond Esveldt Apr 29 · 9 min read "On YouTube there are countless videos that show our hobby. But the majority of those videos are not very interesting to watch. All too often it's just the raw footage that is placed on the internet without any editing. Nice material for those directly involved, for others not really attractive to watch. Yet some of the movies are noticeably better..." Electricity for Model Flyers Part VI: The Care and Feeding of LiPo and NiMH Batteries Peter Scott Apr 29 · 10 min read "Lithium-polymer batteries are impressive. Unless you are planning to boil a kettle, shorting them when changing connectors is a bad idea as I discovered. Luckily a window was nearby. That, and avoiding a full discharge, are the only vices. Otherwise they pack a decent amount of energy into a compact package..." Here's a great way to cheekily comment on all the regulations coming down the pipe which will undoubtedly impact this thing we love to do. The slogan worked for skateboarding, so why not RC soaring, right?. Check them out in the RCSD Shop   Sponsored Shinobi | A Home-Grown Moulded Fuselage Part VI: Here's Where We Become Pin/Ball Wizards James Hammond Apr 30 · 10 min read "Before we get into alignment I will say one thing about joining the laid-up parts in your new moulds because it has a direct effect on the end results: I do it wet with the layups still soft, or at least green and preferably immediately after finishing glassing the two halves. I have never tried to do this operation dry, on cured mouldings—mainly..." The Tip of the Ed-Berg The Immaculate Ejection Bob Dodgson Apr 30 · 5 min read "Gary Brokaw, perpetrator of the famous AFART (Automatic Flap Aileron Reflex Trim), the Automatic AFART etc. staged a real attention grabber, as he was getting boringly high in the standings at the 1989 AMA Nationals in Pasco, WA. Gary, always the consummate showman and special effects wizard, rigged his Camano's radio system..." Quick Covers (Revisited) I guess we can blame the catch-all 'supply chain problems', right? Tom Broeski Apr 30 · 3 min read "As is sometimes the case, product specs don't age well, and that was the situation with the previous article of mine on this subject (see Resources, below). A number of readers had trouble finding the product mentioned therein. So I went on a hunt for an alternative which I could test and see if it met the spec. Success..." The Trailing Edge Momentum The NEW RC Soaring Digest Staff Apr 27 · 4 min read "Merriam-Webster dryly defines [momentum] as a "strength or force gained by motion or by a series of events&rquo;. Yuck. We like iconic Scottish singer-songwriter Annie Lennox's take on the subject much better: "When you're...successful, things have a momentum, and at a certain point you can't really tell whether you have created the momentum, or it's creating you."..."
