This may be further house cleaning after the ousting of Hightower. I had met Chad last summer. I didn't think he was a bad guy. He had some fans and some not so much. There were quite a few people who believed he was just one of Hightower's yes-men...

Did a little looking and found some detail here:http://www.faa.gov/aircraft/gen_av/ultralights/sfa/. Looks pretty straight forward as far as paper work. Did I mention I hate paper?
Wow, I just checked on it.. Looks like all you have to do is print it out and fill in the blanks and carry it with you. Looks pretty darn simple for you! I can't belive our government made something to do with airplanes this easy
Looks like I better get on the laptop tonight and start looking for central places to visit!

Does uncle Sam let a Canadian fly in with an advanced ultralight license? Would have to check out the cross border requirements to fly over there.
I am not sure, I will have to check out the requirements for us getting to your side also. Do you need a transponder to fly on your side?
I would think that your ticket is probably pretty close to our sport pilots, maybe there is some reciprocity
I know...
Lets all join a couple thousand other close friends at Wittman Regional Airport about the last week in July!
If I can get my hitch rolled over I may be able to pull it off Larry, but right now I am scheduled to be working then... damnit!

I'm right at Whitehorse. I generally fly off of 2800 foot strip on the west side of Whitehorse called "cousin's airstrip". There are a few ultralights around but I only know of one Avid magnum that a buddy has. A few chinooks and challengers. Couple of kitfoxes but I don't think they are getting any use. Lots of cubs, aeroncas, cessnas etc. around here. There was a flyin down at carcross today but -26 celc. is down right cold in my plane so I didn't go. Much below -15 and the heat just doesn't keep up. I'll go on google earth and check out the route. I think for the most part people follow the Alaska highway over here. Cheers.

Just thinking out loud here guys. There are alot of Camping flyins down south so I think we should put one together up here. How many are interested? I am thinking a couple days of camping and flying and hitting various strips and gravel bars. There are alot of places we could go that are in range, or I can have fuel flown out and staged if needed.
Give me some ideas of possible destinations that are doable for you guys.

I know that my ea81 is mechanically on spec. It was a total rebuild, everything new, done by a 'professional' while the previous owner still had it. It runs perfect.I will compression test it though just to know. Burns no oil and fires up like it should. Haven't checked the timing but I see that the distributer is turned as far as it can go for the advance. Warp drive actually recommended cutting the prop down because of the 1.84 reduction. He also said that the 68 inch would still be lots of prop if I up the horsepower later. Apparently there are many smaller props running with a lot more power on gyros. It does have an air filter(foam) and carb heat box system. I do notice that the engine doesn't slow down with carb heat applied like you see on aviation engines(0-320). I'm thinking that is because of the hot water running through the intake. I'm going to take the filter out and see if that lets it breath better. Meanwhile I'll start disassemble on the other one to get the cam sent away. Thanks. Ben
Ben,
Where are you at in the Yukon? I am thinking about trying to put a fly in together this summer for the Avid / Kitfox folks.

If Kitfox or Avid cant supply the original undercambered STOL ribs for your wings, I can send you a pattern. I also have some rib-building fixtures for sale. I can have the Kitfox 1 manual copied which is the same wing.

Ben,
I can't give you a comparison between the stock EA81 and the 100 hp Stratus since I have only flown the Stratus in my plane. There are other factors involved as well such as the Stratus redrive ratio being 2.2:1 with my 72" IVO vs. your 1.84:1 and 68" Warp Drive, but I think the additional HP from the milled heads, reground cam and possibly the carb/manifold set up may be pretty significant. My Avid+ is much heavier than any of the MKIV's mentioned in this post so 1150 to 1200 lb's is pretty common loading for me. With the IVO flattened out I get about 4800 rpm and about 800 fpm at that weight. At 1500 lb the climb is more around the 300-400 fpm range. With the advantage of the IVO IFA prop, cruise is somewhat dependent on how much fuel you want to burn. I typically cruise at 3600 to 3800 rpm and lean to 1450 degrees on the EGT's. 70 mph is under 3 gph, 80 mph is under 4 gph and 90+ mph is about 4.5 gph. I usually am flying at under 2000 ft AGL but I have found when I am up at 4000 I can can lean to about 4.1 gph at 90+ mph. I don't know how much of that info may be useful to you in deciding if you want to have your heads and cam reworked.

Ben, that 20 to (35 advertised) extra hp will surely make a big difference for you - However, you will probably need longer blades on your prop - The shortened blades are not good for climbing either - I am wondering if you may have a slightly "sick" engine - have you checked the compression, timing, Valves, etc?
The Stratus is about as good as it gets with the 81 - Just $7000 more than I wanted to spend at the time I bought mine.
I really dont think the twin carbs are any better than the Holley or Carter 2 brl.
EFI might be better than either, but costs $.

Looking forward to your performance results. 912 comes in almost 100 pounds lighter. Is your engine the 80 horse version?
Yes, 80 HP 912. We will start having calmer day here before long and I can get back to the phase 1 flight tests.

I went to the doctor's office the other day at my wife's request
and found out our new family doctor is a young female;
friggin drop-dead gorgeous!
I was embarrassed but she said, "Don't worry,
I'm a professional - I've seen it all before.
Just tell me what's wrong and I'll check it out."
I said, "my wife thinks my penis tastes funny."

Yup for now this plane will be a nose dragger with the 912ULS. Working on getting ready to rib stitch the covered wing.

Gentlemen. I started at 8.5 degrees but could only pull 4200 rpm static. I took this up to 4425 (needle tach) with 7 degrees static. Going to turn it back to 8.5 to see if it does grab more air and actually get up and go. Too flat with the pitch versus the torque range of the engine with a stock cam is what I'm thinking. By the way I'm no expert. Ben
Just did a little math and the numbers do seem to jive. 582 total weight is 585empty +420crew+90fuel=1095 for 700 fpm.(2 passengers). EA81 total weight is 712empty weight+200me+90fuel=1002 for 800fpm@65. I have the avid wide gear, heavy duty truss, big skis and heavy duty custom tail spring.(home made). I better get with it and up my horsepower. Still waiting for that elusive 912 who must be viewing this to put it on record. B

I'm still curious what a mark IV with the 912 empty weight is. Is it 50 lbs lighter than a sube? is it 100 lbs lighter? And how does this translate into performance? Anybody out there reading this actually flying one? Cheers gents.Ben
My MKIV with the 912A weighs 616 empty. I only have 1/2 hr on it so far so no number to report at this time.

Great place for it for CG but strap everything down real good and check it frequently, it will take a pounding back there. Check your ELT after every landing in rough stuff.
It smooths out when you move the 3rd wheel up to the front! :lol:/>
Tailskis are better tho!

I would sure like to have the formula for fpm - probably got it somewhere, but easier to ask, and memory fading fast!

Ben,
I hope you will be able to give us a comparrison report when you get the new engine installed.
It would be nice if you guys could get together at Tok, or Northway, so the Alaskans dont have to leave their pistols home.
And FAST EDDIE"S is at Tok for good food.
