Got the latest magazine today and there is a lot to read. Also got an extra mag
"Workbench No2." Is it me but I don't recall getting a No 1 mag? If there was one any clues as to when?

John, it's the 2nd supplement, the first was with the Dec '17 issue and about Jets.

Thanks David. I don't remember getting that but I am well behind with my mags. Will have a look in the pile.

Nice mixture of subjects in this issue which seems to have come along very quickly after the last one - or maybe its just age!

I was interested to read Mike Kitchen's letter about expo, which referenced this thread, and questioned the implementation of a cubic function rather than a true exponential. I had thought about this at the time, and I came up with two explanations.
Firstly, a common way to compute a true exponential function is to use a Taylor Series expansion, which is an infinite series of polynomials added together, and converges on the exponential function as more and more terms are added. Because we want anti-symmetry through the centre (so moving the stick in the opposite direction moves the servo in the opposite direction), then we are restricted to using only the odd terms. If we truncate the series (to save computational time) between the cubic and quintic terms, then the stated cubic function is the natural result.
Alternatively, one could argue that since the only purpose of the function is to soften the stick sensitivity near the centre, and increase the sensitivity at the end of the throw, there is no actual mathematical requirement for it to be exponential at all: almost any non-linear continuous function with an increasing gradient will do. However, I assume the function name 'EXPO' was thought to be a sexier name to put in the manual, so it stuck.

Wright Stuff, I can tell you if I was writing some TX software, that expo would be done through a look up table not real time math. Computational time isn't a factor then.

In the Weekenders colum Alex shows a photo of hole saws and says that they are dangerous.
Well I agree that the ones that he shows are as the blades can fly out of the holder.
If you buy decent ones the.blade cannot come out. I use mine on a regular basis in my Black and Dekker drill.
They can be quite cheap for a set of these.

I just got my March RCM&E but no workbench supplement. Come to think of it, I never got the Jet one either. Did I miss someone saying UK only or is there some other problem?

Same here Lorenz, I didn't get them either. I don't know why.

I had a lovely wallow in nostalgia reading the article on dethermalisers... I well remember that diagram for the d/t using a cradle and and elastic band, triggered by a burning d/t fuse, as I built one as a teenager from that very same picture and fitted to a KK Snipe, DC Wasp powered. Used to cycle down to the field with the wing tucked under my arm. Engine would run fine at home, never did get it to start at the field. Those were the days!

Never felt the need to post here but this time there is something I wanted to say. Although I like the magazine a lot Like some others I feel left out as a foreign subscriber. We don't get the welcome present on first subscribtion, we can't take part in any contest either. Not realy a big thing for me, just the magazine is more then enough. Nut now we don't get the extra suplement either. Not the jet suplement, neither the from the workbench one. Keep up the good work in putting the magazine together but don't forget the foreign subscribers either.

I just feel that its a little bit unfair that the casual reader who wanders down to the local newsagent and buys an issue if and when he feels like it gets the supplements while loyal subscribers don't. Is it really because we're "foreign"?

The Jet supplement was just a repeat of what had already been printed in previous copies of RCM&E.

Thanks for the feedback folks.
As Tom says, neither supplement contained brand new material so, if you're a print & digital subscriber then it's all in the digital archive including the supplements themselves. Sadly, the cost of producing and dispatching copies for overseas precludes inclusion.
Selling magazines can be a challenging business these days and occasional offers on the shelves in UK newsagents (particularly WH Smith who - needless to say - sell more copies of the magazine than any other retailer) will come along from time to time. We have to sometimes give the UK casual buyers (still the largest market) a nudge from time to time.
I can appreciate the sentiments of course and we'll keep things under review going forward.

Whilst the supplements are OK, I'm not overly sure that they do very much for regular readers/subscribers to the magazine (depends on the subject, of course). David's comment about "giving casual buyers a nudge" by making the mag more attractive on the shelves of WHS is understandable and fair enough, and also makes good commercial sense, but how about doing something a little different from 'introductions to' or 'beginners guides to whatever' from time to time as the supplement?
I'd like to see the occasional dedicated photographic supplement that covers a particular theme or part of our hobby, perhaps some amusing old photos from the archives, competition photos, best of the shows, large models, small models, splat photos, photos sent in by readers, perhaps a mixture? - the choices are numerous.
RCM&E must have a huge image library going back many years and containing some great material that never made it to publication or could stand a reprise - an ideal chance to give them the light of day perhaps? - entertaining for the regulars and a useful hook for the casual buyer as well. Just a thought.

Just managed to get to WH Smith's and pick up the latest issue - which is presented in a sealed cellophane bag with the words "Amazing Value!" printed across the top.
What it doesn't say so prominently is the magazine has now gone up (again) to £5.50 - which I don't consider to be 'Amazing Value', especially after the quiet disappearance of one of my favourite contributors, and the inclusion of uninteresting new 'old' plans which simply aren't worth looking at any more.
Consequently, for several months I have found myself questioning my continued loyalty to RCM&E, but with today's purchase I am feeling like the balance has been tipped and the end is near.
Dare I say, at least Dick Turpin wore a mask!

I for one am a fan of the new "old" plans. Long may they and Shaun Garrity continue. Also Chris Golds' contributions are always well word reading.
On another tangent, remember when the mags came with free gifts?

Is it true that subscribers to "print only" are able to access subscribers only articles via this site ? If so why not include the contents of supplements with these articles. That way the overseas subscribers will at least be able to read them, so long as they have internet access.
As a casual buyer of RCM&E I always have a quick scan of the contents to see if there's enough interesting reading before parting with the cash. If there isn't or if I can't scan the contents it goes back on the shelf.
