    503 rebuild

    Deskpilot replied to Deskpilot's topic in Thruster

    Many thanks Jason. It seems that my engine is a mixture of old and new. i.e., provision for rubber plugs(early models) and o-rings(later models). The step in the plugs must be due to wear as there's no mention of orientation in the manual. With regard the o-ring fitment, seems I've got the wrong size in a couple of places. I thought they were all the same size. I've been advised that "most people" leave them out and seeing as I have the plugs, albeit a bit worn, I'll rely on them. It would appear that they're there only to prevent the bearings from rotating in the housing rather than providing compression sealing between cylinders or the outside world.

    No-one?

    He should have put a pilot in it. Any kid would have done. Personally, I think a model that size is a waste of time and money. Might as well built it 100% scale and flew in it himself.

    Calling all Rotax 503 experts. I'm in the process off rebuilding my engine and, being a very early(si/sc), it has main bearing plugs in the upper crank-case half. These have a step on them as to indicate a fitment orientation. Anyone know how they should be aligned? Also, when sitting the crankshaft in place, the O-rings (64 x 2) get pushed up so as to be too big Any advice? When I stripped the engine, only debris from earlier rings was present. P.S., engine has still to be finally cleaned so I know it not ready for bolt down.

    Looks can be deceptive. That wing just keeps bouncing back into the correct position.

    Here's a true story re the rear floor hatch in the tail boom. The para exit hatch is located at the rear of the 'upper floor' of the plane, just in front to the toilet door. On one para exercise, a soldier was in the loo when the hatch was opened. He stepped out and fell to his death. After that, a safety device was was fitted to prevent the toilet door being opened when the hatch was open. Ground floor paras went out via doors inset in the Clam Shell cargo doors. For heavy dropped like vehicles and supply pallets, the clam shells could be taken off, and wind director(vortex generators?) fitted. Back to the top floor, It was possible to open another hatch (in the loo I think) that enabled one to climb out onto the tail plane. Great view from up there, but not when flying The plane could also be fitted with rockets to assist heavy load take offs but I never saw them in action.

    Hi guys, thanks for your responses. IBob, I was there in late 60 to late 61 then went off to Yatesbury for my 'fitters' course. Neil, I visited Southend regularly as I was raised in Thundersley. In later years I went the see their Bev and was so saddened by it's condition. The cockpit had been vandalized due to being totally open to young kids with no appreciation of the aircraft. Most gauges has been smashed and part were stolen. Very sad. It's gone to that great airport in the sky now. OME, enjoy that flight, nothing like taking first timers up, especially the children. This is one of my grand-daughters when she visited from the UK. Note the foam, makes headsets 'one size fits all'.

    Yes, and I fell off one. Actually, my first posting in the RAF was to 47Sqdn Blackburn Beverleys at Abingdon, Oxfordshire. We often had to clean the soot from the top of the wings and that required a stiff broom and lots of soapy water. A safety harness was mandatory of course and actually saved me from the long drop. Slippery stuff soap. I was left dangling between the engines until a "Giraffe" (pump up ladder) was bought out to rescue me. The mighty Beverley was a magnificent plane to work on and I wish I had more time with them. Only one exists today it has had its spars cut so will never fly again.

    Seems like my Great Grand-kids are taking a liking to flying and following in my footsteps Tattershall Lakes Country Park, UK

    2-stroke! really. It sounds too slow reving to me but 'll take your word for it.I

    What engine is in that and what causes the whistle?

    Ian, you have been doing a fantastic job running your site but I understand your need for respite/help/change of scenery etc. I just hope that in taking on others to form a 'board' will not end up in the chaos that RA.Aus has been in recent years.

    At least 2 different engines being shown here guys. The 'first run' engine only has a single ignition set-up. The image of the engine alone has twin spark plugs holes per cylinder. Also, three types of valve covers shown. I had hoped to find that they were using electronic valves but not so, would make a huge difference to weight and performance. Before you comment, I'm basing that on the use of them in the Koeninsegg super-car engine.

    Makes one wonder if a qualified pilot was in command.

    If you're brave enough, you could go the Hell and back. Lovely place to visit.

    Will I be able to re-register my T84 Thruster under it's original number 10-1346 even though its been de-registered since 2006 and has been modified by me?

    A couple of clever fore-thinking guys in the US have come up with a winner. Enjoy

    Hi Debb, getting back to your parking problem, how wide is your hangar, how much clearance at the wing tips? Asking and wondering if you could actually taxi the plane in. You still need to get that step fixed and a couple of iron plates would easily do it reasonably cheaply. Pushing the plane out with a nose wheel steering arm would be easy for you to handle as well. Just a thought.
  24. Deskpilot
    Neat, but how are you going to seal it against rain and wind noise?

    Welcome LD, nice to have another South Australian in board. I've flown over Towitta many times but never knew it was there. Where do you fly from and what do you fly?
