I have heard that the 5-foot-long Swiss mufflers are so quiet that you need a horn to warn people at the airport - only hear the prop - This is because they have the most restrictive noise regulations - you are quiet, or you are grounded!

A friend of mine put a 2.5 Soob in his RV and added a muffler sold in the U.S that almost made his that quiet - it had some changeable baffles in it - cant remember the name of it right now.

Weather on the prairies north of the 49th has been so crappy these last 2 springs.More often than not I've managed to have my plane up and flying in mid to late march and now...May 4 and I haven't spun the prop yet?If it isn't cold and wet its cold and windy and that pattern is interrupted by typical bouts of cold and dry! cold cold cold !

The pc680 is an AGM battery and yes, they charge like a normal battery and can be mounted in any position.

If you have a radiator, it's not a 503, if it has one spark plug per cylinder, it's a 532, dual plugs, most likely a 582.  Also, most 532s had an A style gear box.  Jim Chuk

EXCuse mE!?!

Thats not a GeeBee! That's a super duper ultra fast XLi GLX Super Bee with some Gee! ^™ in it!

The thing stalls at 189 Miles per hour and flying it is like taming a angry bush animal.

I would know because I flew single engine fighter planes in the war. This thing, gents, is a completely different kind of flying, altogether!!!

Just ask the pilot, he's holding on to that cowling getting ready for a turn, and that Schnulli (mouthpiece oxygen enhancer) is going on high gear!

The engine will have a placard on the crankcase "mag" side, side opposite the prop.  The placard will say "type 582, type 503....etc.  About 1.5x2.5 inches in size, black.

Thanks a lot for the pictures! It's interesting seeing how it compares to the original. If you have a chance to measure the tube diameters, that would be great too.

Thanks again,

I used the concentrated heat of a plastic welder to soften the glue. Works not bad. Very much like a small concentrated heat gun.

Here are some pics of the seat truss mod on my Mark IV.

Here are some pics of my muffler. It's only about 2 feet long. Didn't have a tape. I guess it's a mini swiss muffler. Not real quiet but it does sound good!

All,

Trying to figure out the engine on a Avid Flyer. The plane has a radiator on the belly. The Intake is on the right side of the engine (if your sitting in the cockpit). I am a newbie on the rotax engines.  

Thanks in Advance.

Leni: no worries, you had me second guessing the two header tanks for a second there!

Luke: the PO left me all kinds of Hysol presents!

Thanks to both of you for the heat tip!

One of my double puck calipers has both pistons stuck like Chuck! I got the other calipers pistons out by forcing air into the caliper. I tried it on this one and nothing happened. I tried soaking it in some WD-40, then some carb cleaner, and basically anything that eats corrosion, and they are still stuck!

Any ideas?

Has anybody tried drilling and tapping a shallow hole in the piston face, then threading a bolt in it to get some kind of turning force to break it loose?

Thanks,

Ron

Those 680 batteries - are they dry-cells? - and does your alternator system charge them just like lead-acid batteries?

A lot of things get powder coated - including fuselages - I am just telling what the engine mount "experts" said, "Powder coating forms a solid shield, which may not show cracks in welds".   And, I have heard the same from others.

 Personally, I don't like PC, but guess it is cheaper than epoxy paint for sales purposes.

That other coating - Anodize - that was put on aluminum - was not so great either, because we found corrosion under it on lots of propeller parts when we inspected them.

Nothing a few grand can't take care of

Gotta a kid that loves a geebee

Looks like they are having a great time

Attlee powder coats all the engine mounts. Powder coat will crack through like paint, but especially on a seaplane mount it will help with corrosion issues like mine had.

Doug the tool that you are looking for is called a torque adapter, if you do a search for 11mm torque adapter it will come up. Expect to pay $10-15 bucks and you don't have to deal with the guys at the airport. I would send a link but this site doesn't allow me to send links from my computer and IE .

Guess I can paste from the IPad.

After the rain we had last week, I might make em!

Very nice set up! I just clipped my Icom over the panel and put some velcro on the back of it. My key and ignition switches are right below it and I have no noise issues. I did start getting noise though after putting my Ivo IFA on. If my squelch is low I get static when I bump the pitch. Be sure to spend the money and get the Icom power supply that has the box in the line.

Bump for Herman

Too bad she suffers from that terrible disease called itty bitty titty

7 hours to the Bahamas - in an Ultralight?   I thought Ultralights could only carry 5 gallons of fuel and be flown not farther than a few miles from the home airport?

 If he can get past the FAA rules and the ADIZ and the Coast Guard, then he has a good chance of being shark bait.........Hope it floats!

Haha!

Happy surgery recovery to your daughter and that thing needs some amphibs! Seriously!
