It occurs when opening the throttle.
When on the glide, there is no obvious porpoising on the glide or when diving (going faster). In short not obviously speed related.
-
Using a Futaba Tx, with assignable switches and mixers, I want to set at least one TX Switch to the throttle position.
The objective being to set a small amount of down elevator (the same as having feed in down trim) to opening the throttle.
How would you do it?

The heading says it all.

Those pictures are spot on IMO. The X3 has been of interest for a long time.
I have seen the Doulas 558 (Crimson Test Tube) at Pensacola, where it is fastened to a wall in the foyer. One of your collective images. It is tiny.
A long with the (Gut less) Cutlass (also in Pensacola), engines and the lack of power was a major issue, many engine programmes failed or were cancelled.

What do others think about the newspapers revelations about Jos Verstappen. Quite a bit a colourful history now being printed in the newspapers, no more coyness, just this happened, to whom, when, where and so on.
Is it in Toto's ( and Mercedes) best interest apparently being seen to be having chats with Jos.
My wife found some information on the internet with respect to the alleged complainant, that is a picture, suggested as a good acquaintance of Jos. That is other than a name, their role. I am left baffled why a picture is supposedly fine, yet no other details.
Then there is the suggestion, that much is a power struggle to switch control of the team from the UK to Austria, and loosening the grip of the principle shareholder of RB racing (apparently a guy from the Far East). Is it about revenue and advertising, or perhaps control freakery or other?
Then what is it the Horner is alleged to have done, other than the very vague allegation.
If Horner goes, would others to, would another team want him, would RB go into decline. Would Verstappen remain, if he were to stop winning races?

Grumpy, Hmmm, who was or is it then?
Surely not some one to nobble RB?

I remember reading that one of the problems with Tungsten Bulbs was that most were coming from outside the EU at prices that EU manufacturers could not match and make the level of profit they wanted/needed. It appears that Low Energy bulbs initially came with a number of issues, damage to some fabrics and colourants, the Lux rating being generous (particularly on start up), that wave lengths not being favourable to human eyes. That the wasted energy was often overstated, in that in the darker winter periods, that the heat omissions supplemented the Central Heating. All of this came from the Institute of Electrical Engineers Mag. I understand that they were leaned on to tone down their observations. More recently I read that LED street lights came with a eye sight health warning.
However when I switch on my home lighting now, I do not notice that they are dim. As for fabric damage, sun light is a similar hazard, so maybe overstated away from the Museums and NT historic housing. Brightness claims (wattage) now seem to be more realistic, or maybe perceptions of the wattage required have become realigned.
The problem for European manufacturers, that these dam foreigners will soon retooled their production lines.
As for lower cost European EVs, a good thing, for those who believe in personal transport. German manufacturers appear to be committed to the top end price EVs and want relaxation on IC cut of dates.
I do vaguely remember that family cars have always been to small, for a family, with nappies, toys, suitcases, never mind model aeroplanes. I need a 4*4 to get down and up to our field, my 2 wheel drive, non limited loc diff, is not up to it in this weather. I do not knock SUVs, I should have purchased one.
As some hint, I you get used to what you have. Not all is what it appears. There is often a hint of self interest in saving the universe, as well as dogma.
-
Predictions done.
Some one dislikes Red Bull or Horner, maybe both.
The latest finger of suspicion is pointing to some one called Jos, Never heard of him!
Max Verstappen is heavily dependant on RB, I hope it is not someone close to him. I have read that one of his relatives, has quite a reputation, delivering many column inches, even known to authorities, Wow.

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.
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.
Why do models porpoise and how to prevent or stop it.

Simon, I did think if fitting a gyro that was activated on opening the throttle, switching off when closing the throttle. Although not clear in my mind, if it was possible.
I had another thought that perhaps mixing in down elevator when opening the throttle, which I had mixed in some 30 years back (if my memory serves me well, with respect to time), I just cannot remember how I did it.
