    Being a bit of a saddo curiosity has got the better of me and I have found that the relevant conversion formula for AWG to mm is Diameter = 0.127 mm × 92(36-n)/39 In Excel, if A1 holds the AWG value then the formula is 0.127*(92^((36-A1)/39)). The cross sectional area is then PI()*(B1/2)^2 where B1 is the diameter. There is no easy calculation for max current as it depends on type of wire, length, number of cores etc

    I find the 4-Max site great for this sort of info. This page has a table giving area, diameter and maximum current for sizes from 8 to 20 AWG. This can then be extrapolated to other sizes. On their servo wire page it shows them using 22AWG for standard servo wire, 26AWG for lightweight and 24AWG for extension leads

    Thanks Carl, but for me it was idle curiosity as I am quite sold on Fusion 360 - even for 2D - but others may want to take up your offer. Colin

    Barrie - it's before the download starts. Colin

    Interesting - I also get the message with the first link, but the 2nd link to the 3D community edition software works fine! No logic there.

    The brown treacle like stuff is the polyurethane foaming glue - excellent for tough jobs but use sparingly as it expands quite a bit. (Managed to transform an indoor model's motor into a useless nose weight when trying to reinforce the mount!) Also look for 'Lumberjack' brand - think I got mine from Screwfix. Just as good but cheaper. There is also a white PVA Gorilla Glue for general woodwork which I am using at the moment and find it works well. More details from the Gorilla site here

    Could be - but if the supplied email help doesn't generate a response then i am a bit stuffed. If they can guarantee there is no transaction lurking in their system that will hit my account later, then fine I'll risk another go - but not at moment!

    Needing to make a large purchase from Argos I thought I'd check the BMFA Rewards site and sure enough there was an offer for 7% discount, so I thought 'Right - I'll have some of that!' But it was not to be. I tried twice to buy the appropriate gift card, but both times, after going through the Visa verification, I just got a grey box with a sad face which when I clicked it gave me a message 'www.icomsavingworks.co.uk refused to connect'. There was an email address to contact for help, so I sent details 7hrs ago but no response so don't know the status of those payments - although they do not seem to have hit my account yet. Has anyone else had problems? Very reluctant to try again now for any other offers!   Edited By Colin Bernard on 17/03/2020 19:41:21

    Guess it depends on the label and surface - I've just had the devil's own job getting the labels off old jam jars ready for the next batch!

    Every so often Aldi has Dymo printers on offer. Got one a couple of years ago and its proved very useful. Restock on the label material every time Aldi has the offer on. (They do paper, plastic, white, transparent and yellow). Obviously you can buy at other places without waiting for Aldi - but since I'm a tight b.......

    I've found that when a bottle appears to be set solid it is often just a skin on top and I can often simply hack at it with an old screwdriver and when I break through I can get at good glue underneath.

    Hi Dave, I don't know Tinkercad but in Fusion it is quite simple. Create your root airfoil in one sketch then create an offset plane at the height of the fin and use that to create the tip airfoil. Then use the 'Loft' command to connect the two. This will give you a solid body which you could export via Tools/Malke/3D Print to your slicer. Then print with the necessary fill setting. Alternatively once you have the fin body you could use the Shell command to give you a hollow body which you could then add in internal strengthening within Fusion. Hope that helps.

    I must admit I agree with a lot of the above. As someone with nearly 60 years in the hobby there was little in the special to interest me. I usually look forward to the special each year for its free feature plan e.g. the Vulcan, but none of these plans are relevant to me. Chris made the comment that he is glad he is not the editor trying to please all the readers. In my view there has been no attempt at all to please the well established aeromodeller, instead the whole magazine is targetted at the beginner and would have been better marketed as a special beginners edition, like some of the model railway mags do occasionally. Sure we need to help and encourage new modellers, but there there also needs to be something to keep us veteran modellers interested too, or else I can see subscriptions are going to get cancelled!

    Its coming on nicely!
