    Divorce
    A woman meets with an attorney to file for divorce.

    The attornney asks "Do you have a case?"
    She replies "No, we have a John Deer"

    "No, I mean do you have a suit?"
    She replies, "No but my husband has a closet full"

    "No no, I mean do you have any grounds?"
    She replies "Oh yes, we have over 100 acres"

    "Hmmm...does he ever beat you up?"
    "No I am up before him every morning"

    Getting a bit frustrated he asks "well, what's wrong with your relationship then?"
    She replies "I just can't communicate with the son of a bitch!"

    That's very cool that the Ivo and polyswitches are working out and thank you for the kind words. FYI, I set the mechanical limits on the IVO so it was a solid climb prop at one end and a cruise prop at the other end. Not really much total change, but made a lot of difference.

    One good thing about doing it that way is that I never had to worry about things like oversquaring (overloading) the engine or anything like that. At either end of travel, it wasn't a prop you couldn't run all the time. I just had to watch the EGT's and adjust mixture to keep EGT's where I wanted them.

    Herman,

    I just bump the switch to take some pitch out after landing. I will go full power on takeoff and bump the switch if needed to make 6500. The switch for my prop is right next to the throttle so I can hit it with my thumb without taking my hand off the throttle.

    If you put limit washers on I would make them nylon. The metal washers destroyed my shaft. I really dont think that the limit washers are really needed with a 582. There is not enough tq in this engine to require very much pitch change at all, just a little bump here and there makes a HUGE difference.

    I will set my prop for cruise by leveling off WOT and bump in the pitch to keep the RPM at 6450 -6500.

    Randy It is great to hear your subaru IFA results.
    Today was an excellent Kitfox day for me also.
    The rains stopped and I had my first flight with the IVO IFA system and with the polyswitches.
    Since it was the first flight with the IFA feature I have yet to install the limit washers for high and low pitch which would set off the polyswitches.
    Leni said the limit washers damaged the jack screw.
    I am looking forward to the polyswitches since I already dislike the IVO breaker since it takes too long to reset when it does go off.
    Some members of this forum do not use limit washers but I found that I have no idea what my pitch is set at unless I do a full throttle run up after each landing.
    I landed on a 400 foot sand bar this afternoon and had to take some pitch out on take off roll to get ideal take off RPM for the 582.
    I did not want to do a full throttle run up on soft sand.
    Thanks again ChrisB for helping us out.
    It was windy today so I have no idea if any speed gain with the IFA but with IFA prop and HACman I have never seen this low of fuel burn at say 5500 rpm.
    The EGT's go down as expected with more pitch and the HACman will bring the EHT's back up.
    I need advice so that I do not damage the 582 with too much pitch even with the EGT's and CHT's at or below where they belong.

    Thanks Herman Oregon 541 404 6464

    Two-stroke powered car
    My brother sent me this link about a Miata that was raced with a Polaris 600 triple. The Polaris was about 550 pounds lighter than the Mazda drive-train. Looks like they had fun with it. The Car and Driver article has a video of them starting it.

    This link goes to a forum that has a few more details

    I just thought that some people here might enjoy the article.

    That should be doable-Just tap into the manifold - maybe an unused fitting - But I don't have the twin manifold on mine.
    A lot of my classes in AMT covered the necessity and use of the MAP on engine power management - (now, if I could just figure out how to use water-injection or that JATO boost, then I could GO like the big boys did it!) ;<)
    I should have stated "ABSOLUTE NECESSITY" for variable or constant-speed props, was what we were taught.

    Randy, That's OK about not selling the prop - wont need one for a while. Can you give me the drive ratio of your engine, the specs on your WD prop, pitch used, the rpms for static, cruise, etc? I know your Stratus runs faster than my Reductions, but the seller only used mine for 25 hours and was totally in the dark about rpms, etc. First said 4800 static/cruise, then 4200....4400??? Believe my ratio is 1:1.84.
    Thanks, Ed in MO

    You have the Subaru, but I thought I'd mention this anyway.

    A friend running a controllable ivo with a 912 had some issues with high pitch full throttle for high cruise speeds. This caused too much cylinder pressure and caused leaking at the bases and heads. Leaking stopped when he gave himself a minimum rpm at full throttle of 5200. You may want to watch your head gaskets if you do this often.

    Just FYI.

    Well I finally got the IVO set up completed and did my run/torq sequence and put 3 hours on it today. I must say it makes a pretty impressive change in my plane. First off the stick controls and the poly switch set up with the LED indicator lights at the limits worked perfect. The REH450 polyswitches seem to be just right. As the motor slows down to almost stopped, the poly switch trips, the LED blinks and it resets almost immediately. Thanks Chris for that wiring diagram

    The IVO prop is great; I can get about 600 more RPM on takeoff at flat pitch which makes quite an improvement on takeoff. It is hard to say how much because the snow conditions were heavy, soft snow at 40+ degrees so the conditions were so different it is hard to quantify. But the amazing thing is the cruise performance. My plane used to struggle to get just a smidge above 80 mph cruise; now it looks like my cruise is around 93+mph. I spent a lot of time breaking 100 mph today; I sure didn't see that unless I had a strong tail wind before. It's burning around 5 gph at 93+mph cruise at 3800 rpm vs 3.5 to 4 gph at 80mph at 3800 rpm but I can still back off to economy cruise if I want to. It is a pretty amazing difference; I am impressed.

    Now after driving 850 miles today I'm the owner of a 912 for the Avid. Now I need to find a mount.

    Dunno. I haven't called the dealer yet, been too busy with work related priorities at quarter end. I do know the question of purchasing new wings was brought up by the prior owner and the dealer seemed less than enthusiastic about it as he would rather have the container filled with a complete, new high profit-margin SLSA. Apparently they are selling all they can import and are weeks into the waiting list. What recession, huh? In any event, a handful of parts such as ribs and drag tubes take up a whole lot less space so I am hopeful on that. If the dealer says no, I still have the option of going direct to the manufacturer and buying parts from their kit vs. SLSA division, or making my own.

    Sounds good, I don't know if they have gas at Shell lake but I can bring 10 g with me in bags. If you need more I know they have it at Skwentna Roadhouse but kind of spendy $7 /gal.
    Hope for good weather and no big meltdown I think I might try to borrow a buddy's bobcat to clear the snow berm at the gate to the lake just in case the snow beside the RW melts too much. I had to straddle a few bare patches of asphalt on the taxiway to get out last weekend and I am sure I will have to start trailering the plane to the snow or lake after this week of warmer weather.

    Maybe not that difficult to go SLSA --> ELSA with the right papers, but impossible to go back to SLSA with out approval from the manufacturer... which ain't ever gonna happen.

    I would never argue the "old" 912 mount is not a total pain in the a$$.



    I haven't seen the mods made to the new mount in detail, but I have seen the one that Dave was prototyping. Much improved...

    That is fantastic news. very nice to know. My information is a year old. Many thanks for the update!

    Was only trying to describe what we encountered so there would be no surprises. No suggesting not to do it. IMHO it is the best option for the Avid if it is a model that can tolerate the weight increase without destroying the useful load.

    Two of my friends are currently running the 912 in their MKIVs. One is stretched and pretty heavy because that's the way he built it, not the way it has to be. His is 670Lb. The other is not stretched and he took care to keep it light. His is 630LB. Not a bad tradeoff for the 595 it was with the 582!

    I understand the difficulties the mount has had.

    Recently a local builder and excellent fabricator modified his mount and Brett was part of this. I think he has since modified the jig to incorporate these changes and updates.

    Nice pics Randy!

    To add a caption to your pictures, when you upload them, you should see them appear in a little box off to the side with the file name. Click the little box that says add to post. You will then see the text string with the photo name appear in the reply window. Hit enter so the cursor drops below the text string and you can then put your caption under the photo. I will see if I can do a little tutorial on it with screen shots.

    HP,

    Nothing is more fun than Ski flying... right up to the point that you get stuck in overflow, then it is the most miserable nightmare you can imagine! I have done it in the Avid before and it's not too bad, but I had one instance where I was in the 180 solo and got stuck. I made up some really colorful words that I am cvertain had never been uttered before in the history of man! Atleast they had never before been strung together like that! If you are going to be out solo flying ski's you need a good rope and tackle set up that you can pull yourself out with should the need arrise. WEll, that or just stay on the full lotus floats all year around so you never have to worry about overflow or thin ice again!

    I should also add that it is possible to use the mount pretty much as-is if you mount the 912 carbs out instead of in. one friend has his this way, but it is far less than optimal in that the top cowl needs to have bumps put in it to clear the carbs and ocassionally on shutdown a carb has been known to shake out of its socket.

    If the carbs are mounted inboard as they should be, the install is very clean and the carbs will never shake off and no cowl mods are necessary to clear the carbs.
