    Engine failure today and forced landing.

    The float bowls fill up under gravity only, and the goal here is to speed up this process. By opening the throttle fully, the low pressure at the venturi maximizes the low pressure in the float bowl, and this low pressure 'sucks' the fuel in. By closing the choke, which is upstream of the venturi, you are further decreasing the air pressure in the carburettor and in the float bowl, thereby increasing the 'suck' effect. I would add one caveat to Roger's advice. More often than not, a hot engine will refuse to fire with the choke closed, and it's possible that you could end up cranking away even though there's plenty of fuel in the carbs; thus, I would be inclined to open the choke every few seconds during cranking in the hope of hearing her fire up.

    FD Production

    The following reasoning might suggest a long-term supply problem for the US market: 1. The Chinese light aviation market is likely to explode in coming years - lots of new money to spend. 2. The fledgling Asian GA market will experience strong growth for an extended period of time, whereas the US market is 'mature' and will not exhibit anything like the same demand. 3. Naturally, every manufacturer wants a head start in a fledgling market, especially one the size of China. 4. AJ manufacture in China. There's a lot of incentives there for AJ to prioritize home demand. That could leave Europe and the US with a long term supply problem of new aircraft.

    Thanks for the report. They're not allowed over here yet, (in the UK) but I think they are so good that it's only a matter of time. Its not often you see an upgrade that offers such a huge improvement without any apparent drawbacks.

    Gravity Knight, Would you care to give us your history with the big bore kit and your impressions after a bit of usage?

    Newbee with landing flap questions.

    That's what I thought. But Roger's point was that in his experience, there's no difference between -6 and -12 regarding top speed.

    Newbee with landing flap questions.

    I can't argue with your empirical evidence, Roger, that there was no difference in performance between -6 and -12, but surely if you change the shape of the wing so that angle of attack and subsequent drag is reduced, it simply has to change the performance too, even if it's a very small change. And if there is no difference in performance, why would FD make a special model exclusively for the US market with its own flap setting? I can't reconcile the physics and your experience with the two negative flap settings -?

    I'm off to Fast Eddie land

    SkyCatcherPilot, on 26 Nov 2016 - 03:30 AM, said: I think there's a lot of truth in what CT is saying. The post above (from 'Can we talk about NASA') may seem reasonable at first glance, but when you actually consider what's being said, he's really saying 'Nobody is allowed to say anything contrary to my opinion, because you'll hurt my feelings and I'm going to create a big fight that everyone will hate'. Effectively, he's calling for an end to expressing any opinion that might offend. Most people don't want to live in such a sterile world, and that's why excessive censorship always kills things. In the NASA debate, there was little to nothing that amounted to personal attacks in CT's posts - he cited opinions and arguments and referenceable sources. And as far as I could see, he won all the arguments. Sure, he might be touchy, but I have to say it was others who dragged things down to trading personal insults. In my mind, that's intolerable. Censors should curb those who bite lumps out of other people, but they should also consider silencing whingers who cry foul all the time and want to throw a wet blanket on any spirited debate because it's too honest and frank for them. In the long run, they're the most dangerous.

    There's something else that may be of help to you in this thread: 'CFI considering CTSW for flight instruction' In particular, look at post 15 and the final two posts. It seems to me that much of the transitioning issues with the CT come from the lack of a visible cowl and the fact that the pilot's seating position is not close to being parallel to the centre line; both these factors seem to require a major mental rearrangement of 'normal' cockpit references. I think the advice offered should help with this issue.

    They are hugely popular over here. They're built by an ethical, family-run company in eastern Europe that has put decades of development and refinement into this design. By all accounts, it's by far the best Avid clone in production, and it's the cleanest, too. No way it'll do 120kts though. If you want accurate performance figures, visit the website of the new UK distributor/builder at www.eurofoxuk.co.uk UK and US models are pretty much identical airframes, I believe. They are very popular here as glider tugs and you generally hear very good things about them.

    CT - Going the way Eddie went isn't a good way to go. Sure, there'll always be someone somewhere who will get offended at straight-talking people (like you) and the reverse is also true - there'll be times when we get ticked off too. As the good Lord said, 'offences must come'. However, don't let offence stop you from speaking, because then you've lost and in this case, so has everyone else. In my view you are among the top four or five contributors, especially because you are willing to question conventional wisdom and to defend your view. That makes everyone look again at what they hold to be true, and that can only be a good thing. I'm assuming your intended exit is over the current space exploration post, and if that's so, permit me to suggest that the issue is not one of political correctness versus freedom to speak your mind. Rather it's a simple one of submission - the moderators want to keep NASA out of it, and all we have to do is respect that. So, in summing up, what I'm really saying is, Please don't leave!

    Repairing a $1300 part for $15 + shipping

    Corey, in some cases R&D does justify high prices, but that's a simple PCB that any electronics guy could draw out on a napkin over dinner. R& D costs to design that would be negligible to zero. I think the reason for the high price is more like: we have a captive market so we can charge what we want. Of course one doesn't begrudge a good profit, but within reason, please! The same astronomically high prices are commonly charged for PCBs that come out of heavy plant, agricultural machinery and industrial equipment, so it's not just aircraft manufacturers who make exorbitant margins on such items. They do it just because they can.

    Congratulations - that's a great use of limited knowledge to make a fix. Combining limited knowledge with a bit of sound reasoning and a willingness to experiment and learn new stuff can go a long way - I love it. What I don't like is manufacturers charging such astronomical amounts for PCBs that cost literally a few dollars to make - $1300 - come on!
  13. I think admin makes a good point - while nobody wants a brawl, neither does anyone want an anaemic forum where you can't debate something vigorously and thoroughly. In my view, the 'acceptable line' is crossed as soon as one person in a debate takes a personal swipe at the other. Often these are innocuous little comments, but they are always personal in nature and they always succeed in changing the debate into a personal fight. I would also add that I have observed more than one person here making such comments. It always takes two to tango. I would suggest that anyone who makes disparaging remarks about another individual should come under the three strikes rule - no questions asked. Cite a few examples of what this entails so everyone is clear on it to start with. That might keep the discussion lively, but without allowing it to descend into innuendo or insult. (Such comments are usually emotive in nature rather than factual, and they are a clear invitation to argue personally rather than debate a subject. For example, I would say that Post 28 in this thread is a good example of the type of comment that should be banned.)

    Flight Design insolvency

    For heaven's sake, read the posts - they're not bankrupt! (See post 396.) Once again I'd like to reiterate that many members of this forum are interested to see what the settlement will be, if any, for customers who prepaid. I hope some of you will let us know when everything is settled and it's appropriate to do so.

    Flight Design insolvency

    Broadly speaking, in a bankruptcy, existing assets are seized and the proceeds are arbitrarily distributed among creditors. However this is not a bankruptcy, so all the assets and liabilities will have to be negotiated. FD's liabilities include those customers (creditors) who paid in advance for aircraft that were not received. I am interested to know what kind of settlement is achieved in these cases.
