The port bottom one should be changed to 80 degrees outlet tubes from Rotax. Don't forget to take the pump of first. New seal must be added when putting it back. Also the upper tube has to be removed in order to get the bottom one of. 120-130 degrees Celsius is what it needs, locally. It can be a good idea to wait until the engine is mounted. After the new tube has been connected it must not point to much downwards i.e. as close as possible to the support ring. Otherwise the hose will get too close to the silencer. (My was to close and have to take the pump of and start over again) By the way. ROTAX calls for Loctite 243 instead of Loctite 680 in new manuals. This probably because 680 is very strong and difficult to deal after cure.

They can be heated up and moved. But you only have one shot at it and you need to get it hot enough, otherwise there is a good chance they'll leak. Alternately, take them out completely, clean them up and reset with fresh Loctite.

Guess what the postman's just brought me!! One Mod 70! I should explain, I asked to be prioritised for my 'Classic' (Kit 71, G-BXLK, 400 trouble free hours) because, although not on 'the list', as the Permit to Fly ran out on Thursday of this past week by the criteria laid down I'm grounded until both annual AND Mod 70 are completed. (I'm also now building an 'XS', kit 494, but being no where near putting the lid on I asked Roger to put me to the back of the queue). So, I have it, and I think Europa should be commended for this speedy delivery. I shall email them accordingly. Next question, do I want to fit it .........? I WILL fit it, obviously. But do I WANT to fit it ...... call me an arrogant 'big head', but I spent a very long time setting up the restraining cables in my aircraft, and without turnbuckles (only 'cos I'm stoopid and didn't think of that :-) and the existing set-up works perfectly, no signs of distress, no sideways movement to speak of, doesn't rub on anything, doesn't clonk from side to side, no ground loops or heavy landings to have weakened it or any of the multitude of other parts that such events may inflict on any aircraft ........... but, like others on this forum, I'm only an amateur engineer, so what do I know .....? Do I WANT to fit it ................ ummmmmmmmmm. What if my second Mod 70 for my XS arrives a few months down the line, marked as 'Mod 70 Mk 2', with no rubbing strips included and, instead, cable restraining lugs welded on ........ ummmmmmm ........ errrrrrrrr ......... Would I want to retrofit a Mod 70 Mk 2 to my 'Classic' ....... ummmmmm ......... errrrrr. I think Mike Parkin and others have raised some very pertinent issues. Added to this, I have a personal problem! My other 'toy' is a Gazelle helicopter, hence I'm a helicopter pilot too. And what that means is this ....... as American newsman Harry Reasoner once wrote:- Airplane pilots are open, clear eyed, buoyant, extroverts, and helicopter pilots are brooding, introspective anticipators of trouble. They know that if something bad hasnt happened, it is about to! I'm uneasy. I'd like to know more ...........

If they don't make a profit, support disappears, along with our dream machines! And looking at what you get for 58 including carriage and tax, if anything I'm concerned they're charging enough. (Now I'm REALLY unpopular!). I suspect if I asked a local engineering company to make that lot, the charge would be easily into 3 figures. I think they're being VERY fair in charging what I suspect is barely, if at all, covering their costs ...........

Please put me in the "turnbuckles too" category. It was short, sharp and dead easy compared to using four hands to tighten, adust and fabricate inb one swell foop. I see no advantage whatsoever to cutting the apronstrings and throwing them away, so - barring Europa permission, I'll take the new rod to a welder and have the ears for the turnbuckles put on. My reason is greater than above. Once in, is was so easy to adjust the turnbuckle tension to achieve centre position of the weights, I had to chuckle. In fact for future adjustments, I have six t'bucks in all - two on counterweight arm, two in tail section (tailwheel cleanup) and two in centre section of rudder cables. They are marked with liquid plastic to indicate proper re-install position and tighten/loosen direction, so I can actually 'do' them without looking directly. To Tim Cripps - if you haven't ordered mine yet, please indicate desire for cable flanges on new rod............... I will take "no" for an answer but only if everyone does...

Ron also told me how to set things up to check this measurement. His setup worked nicely even with the entire gear assemble installed. ( it isn't any more ) I installed the swing arms per the manual, and went on my merry way. Did I miss, somewhere in the manual where it says this is a positive over center stop and a way to check this, or a measurement? I searched the old archives ( thanks Andrew, http:// www.sarangan.org/europa_forum/ ) and found a measurement of 1.5mm, . 060 or 1/16. I was much luckier than Ron, removing the powder coat from the stops got me dead even. I think if I use a little blueing on the swing arms then file the witness marks off the stops, I just might make the 1/16th of an inch, and have flush contact. But now my FL24 up and down gate is junk and the rubbing block has to come out, and all my flap setting have to be redone. Wish I new about this sooner, but on the bright side I didn't find out about it the hard way. I was standing near a 80 inch valve once when a 2 1/2 inch hardened steel actuating arm snapped like a twig, because someone set a positive over center stop. Funny how things like that have you blocking out the very idea of a positive stop with out even thinking about it. Chat Later, Steved. ________________________________ Message 9 _____________________________________ Time: 11:47:00 AM PST US From: "Rmi Guerner" Subject: Europa-List: Mod 70 From: "R\351mi Guerner" Europa-List message posted by: "Rmi Guerner" I am not happy with the design of Mod 70, especially with the lack of positive lateral guidance of the balance arm and those awful rubbing blocs. From the description of the incident, I understand that the part which broke was the AN490HT8P fitting. So why is it necessary to replace the whole balance arm assembly ? Providing our authorities do not force us to implement the Mod 70 as it is , I think I would do my own fix as follows : Do not remove the cables. Do not remove the balance arm. Remove the bolt on the lower arm. Remove the TP18A/AN490HT8P/AN316-4R assembly without changing the original adjustment. Design and machine a single piece replacement. Make sure the 4.8 mm holes are drilled at the same distance as the original assembly. This would allow the same tailplane movement range as before. Install the new fitting. I see a lot of benefit in this fix, when compared to the Mod 70 : the cables are retained. No possible additionnal friction on rubbing blocs. No threads to be stressed. Easier to fit. Cheaper. Am I missing something ?

It seems to me this would be a much simpler approach and permit us to retain our Turnbuckle adjusted cables!
