As a EASA/UK PPL SEP pilot, the lack of understanding of each others responsibilities for safety, and in particular belligerent disregard of the consequence of one's actions must be verging on more than a breach of CAA regulations. As an aside the increasing use of the term 'pilots' within the FPV community is mildly irritating, where the training including both theoretical and practical skills together with exams , written and skills tests of competencies, including regular currency ratings checks required is not reflected, but by adopting that mantle seems to imbibe some misplaced authority.

Concur with Zflyer. FlyingTech are solid reliable suppliers. I've been using them for years

I've had several lathes and milling machines over the decades. Please don't be seduced by the usual players, they are all the same base chinese stock, with play on the controls. Doing any precision work at the scale you wish will be disappointing. I can recommend Warco range. They are well made, with little backlash, inspected thoroughly and aligned before delivery. If a little more expensive, you'll save by avoiding having replacing poor cross slides etc. The digital vernier gauges on the travel are a boon.

Gorgeous

Excellent Alan, that'll do nicely. Ordered. Very many thank for taking the trouble

Thank you John, very kind to go to the trouble. I'd seen these but there weren't any dimensions

Embarking on a 20" Vickers FB5 Gunbus about 90g AUW inc batteries I'm trying to follow the recommended powertrain and opted for a 4-MAX: PPOM-1410-2900 C05 4-Max Micro Brushless Motor Max Amps burst 5A. The ideal ESC would have been Tornado XQ XP-7A Programmable Brushless ESC | Modelmaniacs which seemed to be very common, but no longer available (not from modelmaniacs dumfries who had the in stock but just refunded and revised stock as not available) After several fruitless hours trying to find a replacement, I wonder if anyone could recommend where I might try:- The XP7a was 22x12x5mm and 5 grammes I don't wish to go much bigger/heavier, nor order anything from Amazon from China with a 2 month lead Closest is:- 4-Max Brushless Electronic Speed Controllers 4M-ESC6A ESC from 4-Max but even so that's an overkill Robin

Excellent, Anders. I'm assembling materials for a Vickers FB5 Gunbus

Ordered cut parts 17th February, arrived this morning, for the FB5 Gunbus plans. Very pleased, not only with the speed of turnaround, but as I was expecting only wing ribs, most of the pre-cut parts and sheeting too. Very little to obtain to complete: carbon rod and some strip. Pleasantly surprised Robin

We used to be well blessed with indoor flying during the winter months, one in Bishops Cleeve, Gloucestershire, one in Evesham, Worcestershire. Both had healthy attendance before the pandemic, but it seems that Evesham at least hasn't been scheduled back on. I've yet to check Bishops Cleeve, but as it is the same convivial bunch of chaps, I suspect that hasn't restarted. There used to be one in Gloucester. Does anyone know if there are in the area, and if so any contacts. I miss the conviviality

Not much use if I can't see some basic data eg wingspan motor battery size. It'd be like buying a Maserati blind, might be beautiful, but completely the wrong model

I'm completely fascinated by Warbird Replicas. A most intriguing business model. Visited many many times Members here speak highly of them, and tantalise with builds of aircraft that are really more than interesting. I'm really very tempted. However on visiting the site, there seems only one kit available, and no catalogue of what could be or has been available in the past. So how does one encourage the manufacture of kits, if there isn't a catalogue against which to declare an interest and generate economic demand?

Excellent response. Order Matek f765 WSE late Thursday night, dispatched Friday, arrived 11:00 am Saturday.

Perfect. That's what I was planning around identical motor/esc and battery

Well, that's an excellent evocation. What motor/esc battery did you settle on?

Excellent, John, and a lovely clean simple evocation of a pusher too. Is that own design? Robin

Thank you very much Robin. I have a cnc mill which I use for live steam model engineering, together with sketchucam which includes aerofoil sections, so rib manufacture isn't an issue. I'd already reconciled myself to traditional built up spar and caps, hopefully with CAD interlocking. However, research to date hadn't thrown up this sectional drawing which is tremendous. So very many thanks for taking the trouble to post this Robin

Thank you Pert, the doculam is a good tip if I can find some very thin.

Thank you Dad-flyer. As you say, it's not a solid skinned wing but open structure. So it looks as though traditional balsa then Thank you

Thank you Leccy. That opens up a whole new avenue Splendid

I'm about to start my next project, probably a Vickers FB5 Gunbus, about 36" wingspan. Electric Thinking of the materials, carbon fiber rods come to mind for much of the birdcage, and probably wing leading edges, and wing rib lateral box spars. However, interest has been piqued bu some modellers venturing into to using alternative materials to balsa. I would probably CAD/CNC (that's not laser) most of the repetitive wing ribs and was wondering if I should stick with tradition balsa ribs. 2 or 3mm Foam board or depron? Anybody successfully milled these? But the concern is covering. As the preferred method of covering would have been natural solartex, which seems to have disappeared, it looks as though I'd have to resurrect unused skills in tissue/silk with dope. Would depron or foam board withstand the cellulose thinners, or would they disolve. What think? Traditional balsa or something new? I'd be most grateful for any experience and advice. Robin

Thank you Frank, very kind. In the end I applied pure logic to a stick with a fixed range, and applied % mixes to itself dependent on the position of a controlling switch. I'm sorted, now have to separate ranges each of 6 positions, 12 total on two pairs of switches.

I suspected, Denis, that it would be difficult here as it's relating to mode switching on a flight controller for a fixed wing Line of Sight INAV/Ardupilot aeroplane. Thank you nayway

Gen 2 DX8. I'd like to set up two channels, each with 6 modes for INAV: 6 non navigation modes on one channel, say AUX2, and another 6 navigation modes on another, say AUX1 I've seen one guide setting up AUX2 employing the FMode B switch and Gear A switch with AUX2 -> AUX2 mixing, but for the life of me I can't figure it out and doesn't seem to work. I'm missing something here Spectrum DX8 2 Switches 1 TX channel 6 Flight Modes - Blogs - diydrones Could someone guide me through a set up of assigning switch to channels, throws and mixing please?

Happy to do that. Perhaps on the scale sub forum rather than here. See post there. I can understand the comments here. I bought two of these. One for myself and a gift for my flying buddy( full size) who shares a similar passion for fine authentic live steam scale specialising in the pioneer era. We both dabble with rc and have similar tastes, early pioneer aircraft. Hence the gift. We have others. I started mine back in November/Decent. As probably perceived I'm reasonably skilled and can certainly follow instructions. However this is the second attempt at construction. A fundamental error early on and only apparent much later meant that it had to be completely dismantled and re started. It's OK, but I know it's flaws, but that is for later. Flying yesterday, David was relieved that I offered to build his with the intention that he test flew mine with some doubts. He brought his kit of parts and now i have them here. So, I'll dismantle mine and rerigg and improve the control lines. Then do the second example. The construction is 'novel' and if i approached this I'd probably CAD, use different materials and some 3D printing.
