My Frog 100 never even fired. I wore it out just by flicking and flicking!!!!!!!!!!!!

The measurement system that one might want to use depends on what you are trying to do. Using a lathe - mm and its subdivisions is OKish Doing woodwork - a saw cut is about an 1/8th of an inch. Also many things built years ago were done in feet and ins Centigrade for measuring human temperatures is pretty useless as it does not have fine enough increments. When I use a weather website I always set my temp. default to Fahrenheit. I would vote for all the old measurement systems being taught in schools then pupils might be able to think in bases other than 10 and 2, thus achieving better mental flexibility. Lets face it there is nothing special or magical about the number 10 to be used as the only base, I would vote for using a prime number like 13. If 10 is so special why do we still have 60mins/hr and 12 months/year etc The metric system is all Napoleons fault anyway and he did measure stuff wrongly to set the standards for rulers etc, so a metric ruler has no actual comparison base in the real world. After we went metric here the UK was just about the only European country where you could not go to the local market and buy a "pound" of butter. The pound did vary a bit from country to country. What did we do here? we punished shop keepers who continued to mark up produce in lbs!!!!!!!!!!!!!! For modelling purposes an Imperial drill set together with a Number Set is much more useful that a metric set I still feel that measuring vehicle speeds in light years make a lots of sense..... 🙂

There is no standard answer to the question what is a good IR?, it depends on the number of cells, the capacity, how you have used the batts, how you have charged the batts, the make etc. Generally large capacity batts have lower IR per cell than small capacity batts. What you have to do is measure the IR for every cell of every battery that you use and record the information. If you have not already done it label each of your batts. After a period of time like two months repeat the exercise at exactly the same temperature as your original readings. A small change in ambient temp will make a noticeable difference to the resistance measured. What you are looking for in this information about your batteries is for changes in the IR of cells. Usually if done accurately IR becomes higher with age as the the chemistry of the "ode"s deteriorate. If all the cells of a particular battery have drifted about the same amount then it is just getting older. If one of the cells has drifted more that the other cells then you are headed down hill, test this battery more often. If you have any batts that are more or less puffy it is a high probability that one cell may well be much worse than the others. Unmatched restistance + puffy = bin time. Your data will be of no use to anyone else and vice-versa. It is all about changes in the IR of your set of batteries.

Don't forget that the originals had a pretty tacky finish when in use, different repairers in different places, bits salvaged from wrecks etc, so for scale tacky and not quite matching is good. If you want museum or factory finish that is another story.

Thank you leccy for quick response RB

I am in the midst of tidying up my library of RCM&E issues, and I am trying to establish the years that had special editions. I have specials for 2014-2019, I think that there were none after 2019. I have not got copies but there appear to have been specials in 2012 and 2013 were there any earlier than 2012? Many thanks RB

May I suggest that everyone go to their nearest gliding club (full size) and sign up for a number of basic lessons. Be sure that some of these are on strong wind days. Seeing the effects of wind on ones circuits, airspeed, ground speed and landings will explain it all in a very basic way. Good luck to one and all!

It is very good for RM. Today I realised than a valuable parcel should have been delivered by RM in late June. Panic! I had a tracking number and following that up online (regular PC not an app (A Poor Piece of Programming)) it seems they made an attempt to deliver and then sent it to the local PO. Tracking on line told me I could get a re-delivery by quoting numbers on the red-card (No red card had been left on the delivery attempt) so I could not reschedule a delivery. Urghhh So I decided to go to the local PO expecting a lot of trouble having just the tracking number and no red card. The lady in the PO was actually very helpful, after a lot of frowning and squinting at my driving licence and asking what my name was? she went and looked and found my parcel They had had it for 5 weeks and done nothing with it!!!!!!!!! I did not know whether to be cross or pleased - on balance I decided to be pleased at having the parcel after so long. What was in the parcel I hear you asking well umm err - a piece of Spode China, a cake plate in the old design "Christmas Rose" a very nice design. So it is lots of cake this week. All thanks to or inspite of RM.

I have always found "The Balsa Cabin "very helpful and reliable with their gradings and descriptions

No uncertainty and no doubt involved in this just facts.

Stop/start may be a matter of opinion for some, but for me having a car do anything that I have not positively commanded is a danger and a distraction. All of these "aids and features" just represent goodness knows how many lines of code between me and the road not a good thing at all. Even when one pulls out the car key many of the little computers are still buzzing away running down your battery To have code deciding on collision avoidance, lane keeping etc etc is just too dangerous to contemplate It is also advisable to remember that no programmer knows how to write bug free code! This despite many very clever people working on how to be bug free since the mid 1960s. See today's news about disaster from Microsoft!!!! Goodness knows what the world wide cost of that will be, maybe Microsoft will compensate everyone.?? 🙂 I still do not think EVs contribute anything to improving the alleged global warming problem. Additionally see todays warnings about don't charge your EV when the weather is hot!!!!!!!!!!!! Woww must get out my bicycle then Add to the above - all the rare earth metals needed for batts and electronics have to come from basically unfriendly nations. And I do not remember reading about any break through on what can be done with expired EV batteries?? So many unsolved expensive problems with no solutions in sight and politicians would have us running off into the sunset without a life belt shouting hooray isn't it good??

I must own up to using other forums both R/C and other interests and I do not encounter any problems such as we encounter here with them? It would be interesting to know what the real causative agent is? On a slightly different subject I have just received my renewal notice for RCM&E urging me to Hurry as I have 0 issues left, it would be nice to have a little longer warning. This caused me to look more closely at the renewal notice, yes price up again, the notice was dated March 23 2023!!! I guess basic lack of checking. Also I see that the penalty for not allowing Morton to do direct debit is £5 essentially 10%!!! I do not welcome others dibbing into my bank account so I have to pay the 10% penalty or give up the subscription!!!!!!!!!! 10% penalty does seem out of all proportion.

I have had a Proxxon for about 5 years, the most useful feature for me is the ability to tilt the cutting blade. This makes cutting strip balsa with beveled edges for planking very easy and fast. Suddenly planking becomes a pleasure 🙂

In the case of full size gliders the vertical wing tip extensions control the airflow at the wing tip and in doing so improve the performance of the outer sections of the ailerons considerably. Also the overall wing tip drag is reduced, and thus it follows that the overall glide angle is improved. With regard to models one might debate this at length, but perhaps it is permissible to say that the bigger the wing span the bigger the effect will be.

In my opinion the whole business of the instability of this forum is quite shameful "The ITs" apparently have not bothered to reply to David's comment above (last Tuesday) - where are they? The "management" don't seem to be taking any interest or applying a firm hand - where are they? Are we doomed to suffer forever on this forum? 😞 I still remember the good old days when it was not like this at all 🙂
