Yes, of course Paul (?)

I used to love "Whiz Kids" on TV and trying to bring my home-built Z80 up to Ralph's level ! 🙂

Neither of which require a 'service agent' though 🙂 have we really regressed from building our own radios to being unable to replace a broken wire?... I despair! 😁 😁 😁

Other than repairs to physical damage I would humbly suggest that offers to 'service' a modern transmitter with surface-mount PCB and a sealed RF can are a bit of a scam. There is nothing to service, nothing to tune, nothing to adjust, nothing to lubricate (in fact I've seen transmitters destroyed by chemisorption of tiny amounts of silicone oil) The one product that is essential for old pots and switches is a can of electrolube or servisol spray. "Pssst" and there you go, 'serviced' 😉 .

Lots to absorb here, its all very droney as expected but if I've read it correctly there are some positives for us. I havent taken it all in yet but as far as I've read, it does look as though they are actually trying to simplify the red tape. https://www.caa.co.uk/publication/download/25025 .

Only 2 or 3 years ago I bought a new diesel bee from Cox specialist "Xenalook" who seem to have disappeared, it was a custom build with an HD crank. It runs well but the teflon contrapiston idea is tedious and I might revert it to glow 😉

Any Babe-Bee .049 heads please Andy?

and more ... https://www.bbc.co.uk/news/articles/cn4wk013rmlo 18 fire crews !

White vinegar and ear-buds will completely remove it but then you must apply electrolube or similar to prevent oxidisation, over the years I've done loads of furry-battery repairs and this method has always worked for me 🙂 As Martin suggests though, its a good time to switch to lithium, they're so much better!

The question was why do some use more nitro. As a member of 'some' I answered, because some of us use small Cox engines, where its a noticeable benefit. Incidentally there are no Lasers at our club, in fact I've never seen one.

Misleading in what way Pat? I only did a speed-read so quite likely I missed something but it seems not far off to me, much of it is almost word-for-word from our ESR Meter manual... but basically its just an advert for Xtar's own products 😀

For an accurate and meaningful IR reading it needs to be measured on a high current pulse discharge, rather than a continuous low-current charge IR as provided by most chargers 🙂

We see them frequently, very popular at our S/C events and hardly an exception Jon. The opening question was "why do some people use a higher nitromethane content" so an answer representative of Cox users is quite valid I think.

The smallest Cox engines (010,020,049) are so much easier to live with on nitromethane, they can be really frustrating without.

SYB documentation says its 10 to 20% ether, but mostly propellant...

Windows 8 does USB 3, should be fine 🙂

There are various stories of suitable alternatives to amyl nitrate, one suggested "Nulon SYB" (look it up, cant explain it here...) On the other hand, Rush might help, who knows... 😁

Their Parkside cordless Dremel-lookalike is brilliant, not sure if they're on at the moment, Lidl stock comes & goes. Would suit the little drill set perfectly ☺️

Because there are three 19mohm cells in series

I would suggest they're perfectly usable, just be aware that at (say) 20A your 3S pack is dropping a volt 🙂

an unfair title for a thread IMHO 🙂

Good to know for D8 users Mike but unfortuately doesnt suit Geoff's V8 module. I've had a few used V8R4's from ebay, all perfect, theres very little to go wrong with them (apart from the aerial!)

Its all about engagement, thats the hard part. Theres actually loads of stuff happening, loads of projects under way, they just dont make it to the magazine 🙂 In our local group we have a chap printing EDF jets, we have Andy from Angelwings with something new every week, Rob has built an amazing fully-CNC foam cutter, he built his own ADS-B receiver that feeds Flightradar24, we've an old stager who designed & flies his own V twin 4-stroke, we've Shauns huge scale glider builds, we've the retired MD of Wren Turbines with some fascinating engineering stories, we've John who worked on the Sopwith Camel replica built at the Northern Aeroplane Workshops, now at Old Warden, we've a chap who started PIC programming in his late 70s and now makes miniature F/F trackers, we've noobs passing their A's left right & centre. Slightly further afield we've Andy's 'Yorkshire Drone Flyers' and their amazing photography, we've T9 and the DS speed record breakers... loads of stuff going on, and thats just here. Surely this can't be unique to mid-Yorkshire, it must be typical of many areas. Magazine content is out there for the taking!

Have faith Geoff, since then I've done several aerial replacements for the lads... no failures (yet!) 🙂 I'm out of touch with commercial gear but I dont think there is any V8 stuff now...

here you go Geoff, it is a simple length of hook-up wire, preferably silicone: (old lipo balance wire?) https://mode-zero.uk/viewtopic.php?f=62&t=394
