I am using a Ivo ground adjustable with my 912 and highly recommend one for your 503.  Very easy to adjust for Climb, Cruise, and Normal for your engine.  Ivo can get you into the right one.  Other than that, every prop maker's prop is different and the maker will be your best bet for info.

Here is the complete Mark IV 912 Rotax  installation Manual Section IV Chapters 1-7 from Avid dated 11/2/1992.  These are in the tiff format.

I just found out that on my IPad only the first page is visible so if that is the case for you then try it on a computer.

Cool Site!!

Does anyone know what size and pitch of Warp Drive prop is recommended for a Rotax 503 dual carb? I need the specs for a three blade.

Thanks

I replaced the pilots side of my seat with memory foam from http://www.seatfoam.com/ I was going to reupholster it to until I got a few quotes! Upholstery has gotten crazy! The foam was pretty dense and heavy that's why I only did the left side of it. It made it much more comfy on those longer legs. I logged 10.5 hrs in a single day last year with two 3+ hour legs and I don't think it much matters what you have if your doing that...

Absolutely perfect day to fly in south Louisiana today. Got my t-crate and legend cub flying pals out of the hangar and we spent the day burning gas.

Ok, here are my new stats.

I have not yet changed the main jets. Probably should have done that prior to this testing.

I adjusted the prop for the first run. Just tossed a few degrees at the blades. Static run was at 5750. Ok, a bit low, but lets see what she will do. On the takeoff run, I noticed the rpm actually decreasing! Ok, back to the barn. Too much pitch

Set the pitch again and got a 6100 static. BTW, my static is consistently 600rpm lower than WOT. So I knew I was going to get 6700 WOT. Test flew. No love yet. Temps still running up to 1200.

Adjusted the pitch yet again, and I think I hit the sweet spot. 6000 static and 6600 wot. Much better. Mid-range temps stayed in check below 1150. CHT is at 125. Interestingly enough, my CHT has indicated 125 throughout all this testing.

So here I am. I think at at the end of my props efficiency. Either I change the prop for a longer blade, or go with a harder set of gears.

What i want to say, but Im going to let it die, is:

 

The Carbon Cub is a 1320 MTOW (400 useful), 100 mph, light sport, two seat plane.  $175,000

The Highlander SS is a 1320 MTOW (450 useful), 110 mph, light sport, two seat plane.  $100,00 - that will totally embarrass the CC in performance

The Highlander is a 1320 MTOW (500 useful), 100 mph, light sport, two seat plane.  $80,000

The Kitfox SS is a 1320 MTOW (500 useful), 120 mph, light sport, two seat plane.  $75,000 ($89,000 SLSA)

The Kitfox IV is a 1200 MTOW (500 useful), 110 mph, light sport, two seat plane.  $40,000

The Avid Mk IV is a 1200 MTOW (500 useful), 90 mph, light sport, two seat plane.  $30,000

 

WTF?

 

you´ve got to love this comparison.....same fun for way less money! --that does it--- my next plane has to be a FAT AVID to match the owner of course!!

Hey Guys,

yes they are insulation foam; and they are held in place with tabs of epoxy, how ever, I notice that this ones are too tight rubbing and compressing, I would like to be little bit loose like 1/2 milimiter or less and I will covered all around with tape.

Regards

Dimitri

Dimitri, how are those held in place? Thanks, Bryce

Great! I like that patch! Bryce

Be sure and post some pics of the finished product.

Dimi3:

One of the things I've noticed about this type of foam is  it takes a "set", that is it tends to compress  when under load over an extended period of time,get loose and permanently take on the shape of the gap it is filling.If it is the same insulation foam where you are as in my area. I'm playing with marine foam in the gaps as the seal,does a decent job. Working out some minor bugs.

I`m happy with my sling seat, however is old an looks crappy, even thought the plane haven´t flow that much in total since they build it; 

I removed the 2" cushion foam from inside, and I will be putting reinforcements on the critical areas, not cushion but soft fabric instead, few layers; allowing me "hopefully..." to lower the seat without compromising comfort. the seat have some awful welding marks on it, so I bought new textile, and also a sew on custom patch (the one on the picture is a paper copy),

I´m planning to cover the flaperon push rods area making some sort of hanging bags right behind the seat shoulders; much like some of kitfoxes have.

I  have 2 aluminium protections over the push control rods, in case the sling seat fails, I will be not seating on top of the controls.

if you guys see anything wrong let me know please.

What, you didn't notice them down there in the canyon?

Nice video!

Nice vid but I have to admit I kept waiting to see a couple of naked people pop up with that music

Here is my fist attempt at a video I made Thanksgiving day.

the only way a welded tank will work in a kitfox avid wing is to make it a full floater and have an over sized tube put thru on the right angle for a cross brace to be installed thru it,..fore and aft connect points of the tank would have to be rubber mounted in a fashion to allow .25" flex up and down so by doing this a compression tube would also be needed to replace the existing tanks function as a compression tube,..one of the possible down falls,..when the wing is in fold position..you  might get  allot more  flex ie twist which would absolutely require transport braces if trailered 

the other option  if you have the tools required to do it is make a tank that has rolled seams with tank sealer in the rolls / folds,..it wouldn't be hard to do ,..using 3003 aluminum it has good working properties with enough rigidity to hold any manipulated forms.// in the attached pic is how it would look ready to fold the seams..

Pretty easy to figure out what is going on in the first picture.

I'm guessing... Airworthiness?

let's go!

Doug... where did you go?

The toughest HD "Iron Butt" bikers in the 115º heat of the Sturgis South Dakota summer all carry and use baby power for lubrication of the baggage...

when heading out for a long snogo ride it tough to explain to the wife why we put vaseline on our nuts and buttcrack just to go hang out with your buddies... after a few hundred miles of hard riding and sweating the chaffing without it is brutal! 

Dose it come in a larger size?  After all he has big boys.
