quite the opposite, there is no decay on the pipes, I explain, and I heard this from a European car mechanic in comparison to American car, all metals contract in cold and expand in heat, meaning this temperature changes fatigue the metal and that´s why the exhaust pipes rust, because they get warm and cold rather quick, at least on cold weather countries, and much less in warm weather, I remember back in Venezuela 20 years ago, we didn´t have any problem with exhaust rusting as fast as they do here, VW top end models have their exhaust pipes wrapped and for that reason no need to change the exhaust pipes.
Wrapping the exhaust will prevent this RAPID expansion and contraction of the metal, especially for vehicles that are turned on and off very often, this apply to airplanes in some extend... Helicopters wrap their exhaust to prevent heat inside of the engine compartment. check Rotorway Exec or talon for example.

I always heard that wrapping the exhaust was a performance gain in HP and the only downsides were the extra weight and faster decay of the pipes due to the confined heat. Anybody know if that is true or false?

Ed,
I think these are the ones you were talking about...they are small and the pic on the side is of an ultralight with floats. That being said I know the sum of Jack and Squat about floats

Awesome pics as usual Randy! Did you talk to Steve Henry about the SuperStol at all?
I didn't get to talk to him and actually didn't realize who it was until you mentioned him. I wish I had. I got to look over his plane a bit. He had additional strips of aluminum taped on the flaps and aelerons to add another inch or so to the chord. Also bungeed the leading edge slats to hold them open. For some reason he didn't have an exaust pipe from the muffler out through the side of the cowl, just the hole in the side of the cowl and the paint on the cowl was fried in that area. Makes me think it must have fell off and he didn't get a chance to replace it... or it was a weight saving mod.
There was one at the Aviation Trade Show in Anchorage the week before that was really stripped down and set up like the Lil cub with only partial covering, no cowl, had a plastic firewall and nitrous. It was very minimal and looked like it was run hard and put away wet but it probably performed pretty good.

IN AVIATION PARTS - Lady says they are for 2 place cub or experimental, and if refinished and relisted, will be a lot higher - I don't know how to post the ad - and for some reason, the number is not listed for the ad.
This is 12:20 AM CDT - and the ad is good for another 19 hours only - Just wanted to give you FLOATERS a heads up.

Herman,
I thought that all of the Matco MCs now were 5/8 bore - at least that is what Spruce says. The original MC-1 had 1/2 inch bore and a reservoir - So, what MC did you get? Did you buy the inserts? I have several MC-4 sets, but I sold my MC-1s long ago.
BTW: The Cleveland MCs are 9/16 bore from what I have read - half way inbetween the others.

Hi Ed
I just installed the Matco 1/2" bore MC's and what a night and day difference in brake performance over the 5/8 bore with 29" tall tires.
Before the brakes would only hold 3000 rpm and now they hold full throttle static (5400 rpm) with a 912S (100 hp)
I am sure Matco will sell the forked ends (clevis) separate since I needed the longer ones to get my brake pedals forward of the rudder pedals.

I feel accomplished that I can takeoff in under 200 and land in 250. These folks make me look like a 747.

Randy,
I think you pretty much nailed it on Desser's plans. On the next edition though, they, at least I think , they said, there might be tires similar to the ABWs and able to be used on 6" wheels. I guess we'll just have to wait 'til next year to see what they actually come out with. I did think that the rep said they were looking at a new technology for duplicating ABW's tires.

Don't yell at me for being dense, but I am years behind on tires!
What Brand are the 21 - 800-6?

The nanco/nanking/ name of the week ATV tires are for 8" wheels. They can be found for widely varying prices on the interwebs from $40 and up. They will wear quickly on pavement, but they are cheap to replace.
The reason I like the 21-8.00x6 tires I have is because they are basically the same size as a 8.50, but only cost $100 each, they are 4-ply and weigh 10# each. They don't mind pavement and for the grass runways I use they are awesome.

Well it seems that Leni is right about how much freedom you guys are enjoying over the states, don´t want to open a can of worm here about political views, but this kind of government attitude really piss me off; and this builder is by no means A JOKE, his works seems very legit...
I`m afraid I will have same luck with the Swedish Authorities if I do the same over here, so guys enjoy while you can!!!

Mine is also very quiet outside, people asked me if the plane is electrical, however I would love to have a quieter cockpit, when I speak on the radio some of my friends complain about background engine noise, I`m using 3 different materials for the isolation they are light not that heavy. I will post more pics once they are fitted.

Hey Bryce....long story short, I free fall from a latter 2,5m fixing my new house and landed on my left ankle, like a say nothing that a 8 weeks of inactivity and a good surgery with a couple of screws can´t fix, how ever it will take 4 weeks more to be fully up and running, can´t wait to fly again!!
in the mean time I´m also busy fitting another of same engine on the plane, adding instrument on the panel, such as MGL E-1 engine monitor, Fuel Flow computer also MGL, the new radio, and a complete fuel system; reconditioning the seat and behind the seat, also a baggage compartment, sound/temp isolation, ETC...
I really want to go for a long camping trip this summer with my buddy and produce tons of videos along the way.
regards

how about yourself, bryce, haven´t seen any videos from your little robin bird!

Where do you get the Nanco 21" - What are they, 6" or 8" and how much weight and cost? Tubeless, or not?
Are they good for on pavement or off, or both?
You can tell that I have never ventured past McCreary tires. Better / Lighter than 8.50 x 6"? But Leni says that he cant find 8.50 4ply anymore.

Thanks Doug, that would be the tab I don't have. Is that your outlet pointing diagonally towards the side? I thought it should point straight to the front? maybe its not as critical as I thought. any other pics of attaching it without the factory mounting tabs welded in? I'm thinking of using hose clamps somehow

I may need to replace the ends of the MC rods with forked ends, but I have not found where Grove or Matco offers these separate.

I ordered from Matco the 1/2 bore MC's.
Mike
You are correct about the the more pedal travel required when using smaller bore Master cylinders and in my case it is a non issue and the only way I can get the brake performance I need for 29" tall tires.
I could have stayed with the 5/8's bore MC and gone with the dual caliper system per side that Matco offers which many of the Just Highlanders use.
The dual caliper system would also increase the pedal travel

It is definately inhospitable country once you head up the Knik Glacier there is no good place between there and Valdez except a few miles of snowfield at the top of the glacier, everything else is vertical or knife edge rocks or ice or cold ocean. I do like the way that Subie hums along though; after 325 hours behind it it does help build confidence in it. I don't want to get complacent with it but it is about as close to operating like a car as any plane could be. I still pop the cowl and check things over before every flight though.
Oh, I guess I should learn to spell Valdez; sorry to all you Valdez folks about that.

The Lil Cub was covered with the Oratex. I didn't ask him what weight he used but suspect it was the lightest weight 600 since you could see the light through it. He didn't even have any wing tips on it; you could look right into the end of the wing all the way to the fusalage.
I think Paul got some of the most intermittent gustyness to contend with of anyone, on both the heavy cruiser category flying his 185 and the bush plane category with the cub. He managed to get the bad wind for both on each pass. Still did real good.

This are some of the OLD installation photos I had on hand, the electrics were VERY wrong, and the radiator as well was very badly installed... instead of bolting the radiator on a frame to the engine, I decided it to let it "float" on a small compartment on the front of the cowl, works quite well, but in HOT summer is not that effective, I will go for a belly radiator; far easier.
I will post more pics later.
