    Subject: Re: removing Pitch toque tube
    --> Europa-List message posted by: "Tim Weert" <tim.weert@hccnet.nl> Hi Jeremy, I have done this job a few month ago because I had to repaint the pitch torque tube. It is only possible if you remove all the items above the Pitch toque tube first. Then you remove the Pitch toque tube bracket (port side) with the bearings from the Pitch toque tube, after removing the bolts first. This bracket was glued with epoxy to the bukhead during the building process, but because the alu bracket wasn't cleaned enough we were able to remove the part from the bulkhead with a little bit of pressure. The starboard bracket doesn't need to be removed. After removal of the port bracket you will be able to remove the Pitch toque tube at the port side. (The push rod to the elevator should be pushed in aft position during removal) In our case (aircraft was G-KITZ before) the most difficult job was to loosen the bolts from the Pitch toque tube to the flight controlsticks because they were glued with locktite.

    Torque tube. --> Europa-List message posted by: "R.C.Harrison" <ptag.dev@tiscali.co.uk> Jeremy, You have mixed the Descriptions and Part Numbers. TP 10's are the tail plane torque tube nylon bushes. If you mean the long pitch push tube which passes under the tank down the tunnel, just musing about this I'd say if you have the luggage bay mod. I'd suggest you will have to take it out the rear through the rear bulkhead and fin close out. On the other hand if you mean the Pitch torque tube (CS 10) across the fuselage this is possible since we had a mandatory mod. to do by changing the bearing support caps in it's ends. I would like to know why you need either out ....what can we expect to see on ours? Regards Bob Harrison.

    Pitch Torque tube. --> Europa-List message posted by: "Jeremy Davey" <EuropaFlyer_3@msn.com> :-) You are quite right, Bob. I meant the CS10. No panic on having to take yours out. Mine needs two lugs adding to it for the pitch servo of the autopilot. Any tips on getting the bugger out as easily as possible? I imagine I need to remove: 1) Remove both the guards that stop the tank hitting the roll link-rod 2) Remove one CS10 support bracket 3) Remove (or just disconnect?) the roll-link rod 4) Disconnect the under-seat pushrods 5) Disconnect the steam pipe to the back end Do the roll arms need to come off their torque-tubes? That strikes me as being the job from hell!

    --> Europa-List message posted by: Graham Singleton <graham@gflight.f9.co.uk> From: Mark Burton <markb@ordern.com> --> Europa-List message posted by: Mark Burton <markb@ordern.com> Hi Folks, >> It shouldnt be necessary as they are supposed to be factory balanced. > > The propeller may be well balanced when brand spanking new but by the time it has been attached to the aircraft and a spinner popped on the front it is very likely to need balancing. In the unlikely event that the prop/spinner combo are perfectly balanced to start with, they won't stay that way for ever due to dings on the blades. Apparently, if you take a propeller off and replace it 1/1000" out of centre then that will produce a noticeable amount of vibration. Mark there are a couple of issues here, firstly it's essential to pull the blades out before fully tightening the bolts so that they seat properly in the hub. Also the spinner rarely goes back in the same place. The factory grp backplate is rather floppy, to say the least. I have made graphite epoxy backplates in the past which are at least circular, but they can never be perfectly balanced. I have bought one of Marks prop balancers, to balance the wooden prop on my Long EZ, so I can help people not too far from Derbyshire balance their prop. No doubt there will be something of a learning curve ;-) Graham

That gave me enough space to manouvre the pitch torque tube out of the fuselage. (You can position the roll arm plates opposite sites if roll push rods are removed) Regards, Tim Weert.

    Pitch Torque tube. --> Europa-List message posted by: "R.C.Harrison" <ptag.dev@tiscali.co.uk> Hi! Jeremy I bedded both my tank guards and the support brackets on redux with a cling film membrane under the guards and brackets to ensure they weren't permanently attached ....just in case ! But mark the positions to replicate them on re-assembly. I would remove all the roll linkage but don't mix it up, mark it to relocate it for putting it back all in the same position. I don't see why the radius arms would need removing. I would make a good effort before I did that. Obviously you need to establish the location of the new lugs before you disturb anything too.

    Pitch Torque tube. --> Europa-List message posted by: "Jeremy Davey" <EuropaFlyer_3@msn.com> Bob and Tim, Thanks for that advice from you both. Looks like this will be easier than I'd feared :-) Not removing the roll arms is a big relief! And I know my tank guards will come off no problem. Interestingly, the lugs are not perpendicular to the CS17 steam pipe at central stick. Looking in there, this is by design. The AP servo lugs will need to be perpendicular - so I've measured up for that, too. All I need now is a second person to work the other end of the screws. Well, my fiance did say she wanted to help out on the plane, and she's handy with a spanner....

    Subject: Prop balancing
    0.44 FORGED_OUTLOOK_TAGS Outlook can't send HTML in this format --> Europa-List message posted by: "Alan Stewart" <alan.stewart@blueyonder.co.uk> I acknowledge each case is different, however perhaps my experience might be of value. My WD fixed pitch prop did vibrate significantly when first fitted. The classic spinner was solely responsible for this. I could easily confirm by flying spinner-less (to Scotland and back as I recall) with no sign of vibration at all. My 'economical' solution, owing partly to my Glaswegian ancestry, was home grown. I flew about 12 flights (all on the same day), selectively adding penny washers of various weights to the three prominent spinner attachment screws and recording my findings. I finally found a solution that worked. In the subsequent 7 years, I've managed to avoid dinging my prop, and haven't had any significant vibration. Hope this helps, Alan PS. Flying 'au-natural' didn't seem to have very much affect on performance, as I recall. _____ I've stopped 1000's of spam messages. You can too!

Hi Brian, I will answer on William's behalf. The PV50 is a composite 3 blade electric VP prop manufactured by Arplast in France. It is quite popular in Europe because it is light weight, relatively cheap and it performs well. Quite a few are fitted to Europas. Another vendor to look out for is Woodcomp. This company is based in the Czech Republic and have a couple of nice looking electric VP props (along with lots of other propeller designs). From your point of view, it's a shame the USD/EUR exchange rate is so poor. It makes these European offerings relatively expensive. Cheers, Mark

    Subject: Over Voltage
    --> Europa-List message posted by: "Troy Maynor" <wingnut54@charter.net> Hi All, I have been wondering if an over voltage protection circuit is widely used in the Europa community. I have been recently reading on the Aeroelectric forum of the ups and downs of it, as well as competing designs. It is a little difficult to take the good ideas of many and the requirements of Rotax and graft them all together to make a reliable and safe design and know that it will work without equipment damage when called upon. (whew what a run on sentence) I was thinking that if I used Eric Jones' overvoltage module, that is "more polite" as he puts it, meaning not putting a direct short on the buss to trip a breaker, and incorperating it into something similar to Bob's newer Z16 schematic that is for the Rotax, it might be the ideal situation. Could one just forget all this and depend on the fuses in the diagram as per Europa? see figure Z-16 at http://www.aeroelectric.com/articles.html The kinder and gentler ovm at http://www.periheliondesign.com/LOVM.htm Troy Maynor N120EU Europa Monowheel Classic Left to finish: Paint,interior,engine install, wiring.

Fred A194>> It has. The Arplast has about 6 degrees more twist than the Warp Drive. There is now also a revised "faster" version of the Arplast that has yet more twist and apparently works well on the BanBi. However, it's not for "...slow girlie Europas...." apparently, although no-one has actually tried it on a Europa. Good luck with finding a distributor in the US! Manufacturer of a similar prop (i.e. with similar twist to the revised faster Arplast blade) can be found at http://www.avtek.it/html/eliche.html#E2 although their new "Bayblade" is not shown at that website.

It is an electrically driven VP three blade prop. There is also another similar three blade prop made in the Czech Republic called a Woodcomp or Kremen. This one has now been fitted to several Europas and is available as a constant speed prop. Very good value. Google will find Kremen or Woodcomp, but I don't think Arplast has a web site.

    --> Europa-List message posted by: "Jos Okhuijsen" <josok-e@ukolo.fi> About a year aga there was a thread with the same subject. In my humble opinion there is very little chance of a dangerous over voltage situation with the Rotax standard design. If it ever should happen then there is time enough to switch the generator off before any damage occurs manually. Any added circuitry has its own added failure possibility. The end result could well be worse then the simple, clean design which is laying in front of you. Regards, Jos Okhuijsen

    From: "Erich Trombley" <erichdtrombley@juno.com>
    Subject: Vent lines and the 914
    --> Europa-List message posted by: "Erich Trombley" <erichdtrombley@juno.com> Can anyone flying with the 914 tell me if they have routed their vent lines from the Oil sump and air box so that they terminate just above the air filter? I have seen a picture of this somewhere and was wondering if this has worked well. I seem to get quite a bit of oil collecting on the belly of the plane and have traced it to the vent lines. I was hoping that by rerouting the lines to the air filter, thus allowing the oil to be consumed by the engine would mitigate the problem. Any thoughts? My only real concern is contaminating the air filter with engine oil. Kind regards, Erich Trombley N28ET Classic Mono - 914 Now includes pop-up blocker!
