    I hope the bombs are cheaper than their $325 heaters.

    Shoot if you have the 45s try em. Those little buggers are expensive to buy! Most people run a tiny tach. They are $40 and double as an hour meter. Very simple to hook up.

    Ok. I'll get some more tuning done. Chart calls for one full turn. I'm at two turns and running smooth around 2700. Noticeably smoothed out. 3000 was about where she was previously happy. I'd certainly like to get her smooth at 2000. I was wondering how many turns out before you would consider the 45's? For some reason I have four 45's in my stock so experimenting is cheap.

    Perhaps a clutch is in my future, however I know she can be better than she is now. That being said, I'm not running at idle for long anyway. After start, I will warmup at 3000

    My midrange and top end seem very smooth. But I'll be going through it to confirm settings.

    I did finally install a generic electric tach and reset the prop pitch accordingly. Wow. I have a new airplane!

    Hello Ed, i had some good callings with Siegfried Lanitz the owner. One part of Oratex is, that you can repair the fabrik realy easy. A man in alaska coverd his plane with oratex. He must land on stones an had every landing damages and wholes in his ruder because of normal fabrik. Now with oratex 6000 he had no problems with stones. Write a email for the price to Siegfried, and you will get a answer, maybe he call you back. Martin

    thanks,  plugs are a light brown.  I'll try the primer to see if it will bring up the rpm.  I was wondering about the tach, engine feels strong at full throttle but I dont have much to compare it to,(my KF has a 912)  I have a spare tach that I might swap out to see any difference.  Any ideas on cooling?  The radiator is hot after running the engine so the theromstat must be opening.  Do the water pumps go bad ?  How would you check.
     
    wish it sounded as strong as Joey's in his video's !

    Second place is http://www.uflyit.com/ A company out of Florida that makes aftermarket parts for Challengers. Their bomb cargo pods that strap on the strut are pretty cool.

    How ironic I joined and posted over at Rans Clan today asking a question for something on my Avid. Any chance something is plugged up in the intake or exhaust? Water temp going up would lead me to believe there's high CHT's but it sounds like you have that covered. What's the oil in the gearbox look like? All things lead that the engine is overloaded some how... Bad bearing somewhere? I've never seen a two stroke run good but not make power if everything attached to is it working correctly. The saying is true they run best right up till when they quit.

    Not sure I'm on the right track but maybe leaking seals?  Did you try to pull the choke or pump the primer to see if the revs go up?  This is the first thing that popped into my head, so take it with a grain of salt.  By the way,  what do the plugs look like after this taxeing?  Black= rich   white or gray= lean.  Just when I'm about to hit the send button, I think of something else to say.....  Are you sure your tack is accurate?  Jim

    582 problems
    Hello All,
     
    I need some of your collective wisdom on a 582 greyhead I'm trying to get sorted out.  Let me confess upfront that it's not on a KF or Avid but a Rans S7.  However as a loyal KFIII owner I hope you will be understanding.  ( I ended up owning this thing due to some reckless latenight web surfing and possibly a beer or two)  Heres the deal, the a/c had been sitting up for a couple of years.  It was running fine with about 125hrs. on it before.  We've gone through the motor, pulled the cyls cleaned the rings, decarbed, syned the carbs etc.  Now with the same prop and pitch it wont turn up past about 4800 rpm.  It also wants to run the water temp up past 180 degrees when taxing around.  The egts and cyl head temps are fine.  The radiator has been flushed and coolent replaced.  Anyone have any suggestions where to start sorting this out?  It starts and runs fine.
    Good thing I have the old reliable Kitfox to fly. 
     
    Thanks

    Ding Ding Ding... and the winner is....................RANS with a 27 minute response time, the answer I needed, a part number and a price.
     
    Out of curiosity if you had the funds to purchase a full kit tomorrow and you were hung up between two designs, how much weight would you give company support on which kit you purchased?? For example if you emailed one saying I want to give you 60K of my money and never heard back from them and the other one you got a response back in 27 minutes. Since Aviation management is a hot topic in a class I'm currently taking I am just curious. Me personally I'd have to say it would probably be a fairly large part in my decision only if all other things were equal.

    I shoot for just over 2000 on idle with my 2.62 and E box. You can also lean the idle some with the airscrews. You can back them out 1/2 turn at a time. If you run out of travel you need a smaller jet. Also if you lean the airscrew out make sure and jam in a quick burst of throttle and make sure the engine doesn't bog as it accelerates. If it does your too lean on the bottom end. I won't say it's impossible but it's pretty tough to hurt the engine running lean at idle or just above. It'll quit from fuel starvation first. Don't test that theory in the High or Mid range though!! You can sure tell a rich running two stroke at idle if you hear one after you get yours tuned though. I saw a flightstar taxi in with a 503 on it at our airport one day and I thought his engine was going to jump off the plane it was shaking and smoking so bad. That's a good way to foul plugs and build up carbon.

    Kitfox wings on an Avid
    A while back, there was a discussion about using Kitfox wings on an Avid. Someone mentioned why it would cause problems. I think it had to do with the incidence of the wings. I tried to find the post that talked about it, but couldn't. Maybe it was even on another site. Any remember it? Thanks, Jim

    I'm running a 45 on my 582, but then I have a clutch and almost no load on the engine at idle RPM's.

    Who will the winner be?
    I just sent an email to Kitfox, Rans, Quad City Challenger, and Skyraider using the information from their webpages inquiring about a few different things. Any guesses on who will return my enquiry? Debra at Kitfox is usually pretty quick to respond to my parts questions but I think I used up all my freebies as the last couple of times I never heard anything back.

    55's currently installed. Have you guys had any luck trying to sufficiently lean with the 55 or do you just go with a 45 from the get-go?

    And what rpm do you aim for? 2000? 2200?

    I dont know for sure but it is a least 1-1/2". I am planning on putting some 26" Airstreaks and probably the 8" Matco tailwheel. I want to redo the panel and put a recessed spot for my iPad (Got the idea from the iCub) so i can use foreflight for in flight weather. There is also the HAC i plan on installing.

    It is interesting the differences. I have a model C speedwing serial # 912. I have the external cowl scoop side radiator (for now). The scoop is removeable from the engine cowling. I also still have mechanical brakes (future upgrade to hydraulic) My hangar mate has a higher serial number model C aerobat speedwing. His originally had the radiator angled in front of the firewall inside the cowling.

    Oh Come On! Just look at the stats of problems related to oil injection versus pilot error. What is this, the first in how many years there is a case of the oil injection system being at fault and then it turns out to be the fault of the installer....? This is not an indictment of oil injection..it's an endorsement!!! Cheers All, Mike

    Wow short takeoff.  I haven't even paid attention to my takeoff roll in my kitfox yet.  Been too worried about the fan quitting.  Now that everything is in good working order should be able to work on my STOL abilities a little bit.

  25. EDMO added a post in a topic Leni's answer to the 800 pipes   

    If you study the sound restrictions in Europe, you will enjoy hearing the pipes we use in America - Those pipes shown are small compared to the 6 foot long homemade mufflers that some use - they have to, or get grounded. Tony Bingelis (sp?) describes how to make them in his Sportplane Builder Book.
