I guess we are talking some where between 300 to 400 watts? Running a 3s lipo.

Frank, their was certainly a lack of investment, as an owner of a Allegro and a TR7 the build quality was low, as were the trims, many being extras. This was certainly not the case of Japanese cars. As for my dads Vauxhalls and Avenger, and Metro, not a lot favourable can be said. I also remember the Triumph co-operative, before Bloom came along. Then good modern design, quality build reliable, value for money. Yet others squandered reputation post war, as you hint, kick start, magneto (poor electrical components) and so on. You could write books on the subject, ah, many have, multifaceted failure,(incl a tax regime that was unfavourable) so much wrong. Lets hope we do better with electric cars and the remaining IC markets. Cost to the purchasers is crucial, along with other issues.

Seems standard in our 20 mph zone. No speed traps here, main road and coast road yes, rat run definitely, no.

Does anyone have any idea as to the current draw of a Wot 4e on the standard propeller, with the standard electric motor?

I have managed the predictions now. It seems that two managers are trying their best to cause RB stability issues. I guess if you cannot beat RB fairly on the track, all is fair in love and F1 racing. I am intrigued though about the nature of the accusations, made by whom? If CH were to go, I suspect others would want him, plus others who possibly would also leave, particularly if Adrian Newey and a team totally left potentially in chaos, then you think of the sponsors and what they would do if they stop winning? Then I think of the accuser, how can they remain whatever the outcome would be? Seems I am as bad as every one else🙄 Until the first race is over, my predictions (wild guesses) will be less informed than ever. As pretesting tells me nothing, not knowing what it is anyone is evaluating at any time.

Frank, like yourself I have not measured any similar vehicles, the height and weight issues, is from media published claims. Todays news is an announcement from Aston Martin that they are delaying the introduction of their projected EV models, due to a lack of interest from potential purchasers. It could be that Aston does not have the money, or some other issue. They will continue to build and sell hybrids, I guess that investment is water under the bridge, in addition the cars maybe selling, and could they also be part of the requirement for 22% sold now being electric, with 80% by 2030. I had read that the EU expected the UK to pay a premium for EVs so that EU car production could shift "S" curve premium cost away from the EU market. As for China, in the past it was not the Japanese that were the issue, it was the poor quality, workers attitudes, lack of basic items and price of the UK cars that all but destroyed our car industry. How British Leyland went from approx 50% of the UK market to the position that transpired is criminal, for all involved.

Todays headlines is that are "is China dumping cars in Europe", by subsidies? As they are so much cheaper than cars produced in the EU. Personally I had not noticed how cheap they are. I read a few weeks back that the EU, is considering moving the 2035 manufacturing cut of back some years to a latter date. The weekend s paper stated tha Mercedes have changed their cut of date for IC vehicles. Perhaps to add fuel to the fire, the equivalent EV vehicle is normally taller than its IC equivalent. This will increase the drag, as area is part of the equation as well as Cd (which is also probably adversely affected as "fineness Ratio", dumpy bodies will normally have a poorer drag ratio. IMO, it is the price that dissuades me from EV and the range. The prices can be fiddled by the tax regime, the range is more of a problem (as I cannot get to Manchester and return, without either a charge or high stress levels. Plus my old banger, is good enough to see me out, other than legislation and "Milch Cow" taxing. I also now see the acknowledgement that standing charges must go up to pay for all the extra infrastructure required for electric power.

When I try to open predictions, I gat a page which wants details of my card, is this usual?

The Starfighter was a beneficiary from the X3 project. I have read that input from the project influenced the out line design in addition to more technical aspects (below skin deep). I still have hope with respect to my own X3, in respect to the Starfighter, info on methods of construction and propulsion would be very, very interesting.

As part of the process of starting to ready, I found this piece of kit, hard to miss, on top of the tank hatch. https://www.turbines-rc.com/en/testers-checkers/451-7-led-tower-pro-receiver-48-6v-battery-low-voltage-indicator.html I have no instructions, I am assuming that the plug is plugged into a spare Rx socket. If non is available I guess it is OK to "Y" lead with the power supply.

Robert that appears to be the identical product. There now appears a number of different Glo-sticks that seem to be using the same method. My choice was probably influenced that I could see that it came with a charge lead, with some it was not obvious what was needed. When this one arrived, then another set of issues raised further questions.

Stuart, I just happen to have a few UBECs, God only knows why, just seem to have them.

It is an old DB Mascot, a trainer type model, about 56" span. Being an electric flyer I normally undertake 6-10 minute flight, probably 4 off. Say 40 minutes in total. In the past I would fly 10-20 minute flight, say 3 off, which would be about one hour. I am not sure concentration or boredom would fail that long now. I have started flying electric glider recently and find that by 20 minute flight I am totally board, often having cramp from holding the Tx.

I remember Entropy from both Heat Engines and Chemistry as the disorder that systems exhibits. Which I took to mean inefficiency of all the stages in a process, be it "now heat loss across a boundary, or a increase/decrease in pressure with a change in temperature and so on. In chemistry I was told that in reversible processes, that they could not be reversed forever, as all the molecules would not return to their exact position before the start. That to my simple mind (getting simpler each day) was why all processes have inefficiency's and Nimh etc. all fail, it is all turning to rats. I guess one of Newtons laws (perhaps 2nd, but I am guessing) deals with is why energy runs downhill, hot to cold, or is it all the same thing. In some ways Newtons brilliance was stating the obvious, that no one else saw, in addition to be much cleverer than most of us can aspire to. I just about grasped that the more processes or stages their are, the less overall efficiencies is to be expected. I guess that is why many fixate on one part of a system and choose to ignore other aspects.

As a long term electric flyer, I now wonder how IC aircraft Rxs are now commonly powered. Electric models the Speed Controller commonly powers the Rx, as most will know. In the distant past a small Nicad would be used to power the Rx. I wonder if it is now the practice to used a Lipo or are Nimh now the preferred method?

I have purchased a hand fuel pump. Now I am wondering how to get fuel in and out of my fuel bottle. Do I simply remove the cap and drop a length of fuel pipe into the bottle. Or is it common practice to modify the top to have permanent connectors. I have not been to the field for possibly over 3 months now, so have not been able to look and ask other club members practice. This has been a long Autumn and continuing Winter.

I have purchased a plug directly to glo plug batteries. It supplied with a lead to a computer USB male type connectors. I had some difficulty in connecting the opposite end onto the lead. It required far more force than I expected. This had me wondering if I had correctly connected it, yet there seemed to be no other alternative. Now to my issue, there appears to be no way of knowing if the Nimh is being charged now connected to my PC. I intend to leave it plugged in for about 10-12 hours. Is my only way of knowing the state of charge via a multimeter?

Much that some would take as anti EVs comes from the business pages of the media, the interest tends to centre or be about investment, company performance in the short and long term. I am surprised in the vast amounts of money, spent on EVs development, some having burnt through, I think it was close to a billion, before going bust (vans). As for concrete usage, yep, it seems that the oil industry has used some, although it would or will be interesting to know a comparative world wide snap shot of how much goes into all the platforms and anchors, compared to wind turbines (a few hundred are being built off-sure here on the Fylde). Although comparing energy delivered to some unit of concrete is required. I am not pro or anti oil, I do wonder where we will be without oil, for polymers, lubricants and other non transport uses. I totally agree that the world is overpopulated. We see it particularly in the UK (England). As a country we cannot supply our food needs, even if we all just ate Turnips, (not even a bad joke). As for the wider world, there are issues where ever you look, often with great suffering. As to the answer, until it is recognised as an issue, problems will remain and grow. There are two ancient wind mills here, both becoming uneconomic with the coming of stem an electricity. So called free energy is nor an answer in itself. I read this week that by 2040 (to my mind very optimistic) the first commercially viable Fusion Reactor will be operating. A 5s burst will power an incredible number of kettles. I thought how does that in principle equate to customer demand? I now see that tyre dust is now an environmental issue. 0

John, if I had only scrolled down a bit further, I would have found the option. Why not, there was (and is) a band of adverts of young woman in scantily clothed attire, I did and do not want my wife accusing me of being a dirty old man/pervert, so I averted my eyes. I have got myself into enough bother looking for models, particularly rubber powered models.

It does leave me a little disappointed that there are a number that are so converted to EVs that reports from the media are dismissed. I am thinking generally along the lines, the the second hand values fall faster than a similarly priced IC vehicle, that the range remains an issue for many, also that for manufacturers the percentage of sales for EVs, is falling relative to the rest of their range. There are more reported. I suspect that the high initial costs, are an issue, especially for private purchases, whereas businesses can various tax advantages (at present), although the withdrawal of some, has changed their strategies. If true the premium insurance costs are not an inducement. However Ford have announced that their EV range is going to be centred on the lower cost small size EV market. Not the premium end. I noted in the newspaper this weekend, that a number of small (tiny) vehicles are coming to the UK market. The Citroen Ami at £8000, 50 mile range, Fiat Topilino @ £9000 with a 50 mile range, Dogood Zero @ £ 6000 with 50 mile Range, the one I liked the look of Mobilize Duo with a 87 mile range, then there is the particularly ugly Biro Summer £11000 with a 35-60 mile range. Many media reports suggest that Tim's practice of pre heating the vehicle, battery, seats etc. whilst on charge prior to departure is a must/ or generally sensible, in cold weather. Others indicate that the low quoted range in winter is often due to software having monitored previous usage and the option can exist where the electronics starts shutting functionality off, if the destination is known, and range seems to be an issue. I am astounded by some claims that IC vehicles (cars) are subsidized, they appear to be anything but. Some see them as cash cows. In my case range is an issue, once a month doing a 120-140 mile journey, unfortunately (for me) my present car will almost certainly out last me. I have nothing against EVs other than price, and the ability to carry my models, that few seem to have (in my price range). I do see the elephants in the room, and am amazed at the Emperors new clothes, that some cannot see.

I am being asked for a code, is that right?

There have been other reports in the press that are not encouraging with respect to EVs, one being that specific tyres for EVs (is it all) have shallower tread, also wear out faster, due to the combination of heavier vehicles, high initial acceleration, combined with the shallow depth of tread. One of the issues that probably many have no awareness off is that the underground transmission cables, are often oil or gassed cooled, these cables are armoured (wire) and designed to withstand the forces generated from transmission, they invariably will have significant magnetic fields (as do the overhead cables). There is or was often a lead sheave to help with the mechanical performance. Sub sea cables are similar. As is usual, heat generation is an energy loss. Power stations used to be close to point of use, as far as possible. The Anglesey reactor being close to a Electric Arc Furnace plant as an example that is not immediately. Long transmission lines mean obvious energy losses. On that basis some of the offshore sites are probably less than desirable, nor the remote on sure sites. The various transformers are also a potential issue, needing cooling, full of oil, all indicating issues. Oil is going to be needed to an extent, however the world goes. I shudder at the energy and Co2 released from Cement product. The bases of wind turbines need a lot. Although Nuclear could provide base load energy for homes and transport, it is not ideal of fast ramp up and down. The intermittency of wind turbines under most circumstances do not seem ideal to follow demand profiles. Much of what is advocated is either an attempt to get the consumer to turn into a favourable demand regulator. The alternative fudges come with various costs. With a population now predicted to reach 70 million in the next 15 years, the problems continue to grow. Perhaps limiting the motor power could be used to limit acceleration (thus reducing some some of the issues) and a gear box to deal with the declining torque with revs. It is claimed that EV drivers use the initial acceleration, which has contributed to accidents (I find this a little far fetched, although could be part of the problem)

Am I now registered in the League?

Don, so true

JD 8, many of us knew it as Trawfsnydd as you say strictly the station, although it was seen as a package by many. The point I am really making like so many of the fixes, it is really a fudge that comes at a price, be it a system that is not amicable to fast ramp up, or a system that has issues with no or high wind speeds. One of the major problems that some are so committed to a method of generation (or anything else) that they either do not see the difficulties and often wave them away as irrelevant, or that others no nothing.
