    I added a comment to your Avid Yahoo Group query and will repeat it here, as several folks have commented without your acknowledgement. A quick courtesy post to let folks know you received and appreciate their input is helpful, and will likely pay dividends the next time you post a question.

    The removable wing tips look like standard issue KF tips as well, and the fact that the owner is connecting the flaperon control tubes (all KF models from 4-1050 up require disconnecting to fold wings) all pretty much tell the story here. Again, if all the fellow did was attach KF 5-7 wings and struts to a stock Avid Mk-IV, Steve Winder or any of the old Avid factory representatives would tell you the aircraft was still only good for 1200lb M.T.O.W. ...period. Is the wing physically stronger? Sure, but load that Avid to 1550lb then over stress it once and I suspect the wing is not what will fail.

    IMHO, the owner/seller is waaay too optimistic on his gross weight claim and, without extensive build modification and flight testing documentation, is setting himself up for a hell of a liability suit. You did right to question it. As always, caveat emptor.

    update one year later :
    the primer was the origin of all troubles, now it runs perfectly, i made several flights with no issue and even in hot air with the free air pusher config.
    so my judgement has changed and i'm thinking to put mz 202 in my C model.
    the hard thing is to put 5000E on a poker table to be the lightest/simpliest avid mz202 tester...

    lift strut fairings
    Many have said the lift strut fairings are worth 8-10 MPH on a Avid/Kitfox.
    I ordered the plastic snap on style for my 1 inch diameter Kitfox liftstruts from John Mcbean
    I am looking for alternate methods to esthetically blend the 2 fairings where they blend together at the fuselage end instead of using the aluminum cuff material they supply.
    Maybe the aluminum cuff will look acceptable after all?
    Does Bondo or structual adhesive stick to this plastic?
    What glue do I use to glue the fairings to the lift strut?
    Do you also glue the snap together joint?
    Should I have considered other lift strut fairing material?
    Thanks Herman

    Hey Dave,

    Is that John Stoner's old KF?

    For the 8" wheels, the Nanco tires are about the biggest you are going to get. SuberAvid had a set of 10" wheels made so he could run 25" ATV tires. Your best bet, if you are looking for tires that big is to bite the bullet and get a set of 6" Matco Wheels and mount up a set of 26" bushwheels. Randy has them on his fat avid and loves them! I got tire envy cause they are 1000% better than my 24" goodyears.

    With the Matco wheels it is not a big mod job cause they come with the 3/4" bearings too so it is just an issue to cut a spacer or slide your axle in and re-drill it.

    I cant remember if John had ski's for that bird or not?? If so, we do quite a bit of playing in the winter around the valley and up the river..

    Thanks Larry! Elevator linkage bolt issue
    When Larry went flying with me the other day he noticed I had a little bit of slop in my elevator linkage back on the tail where the clevis attaches to the elevator horn. I took the bolt out and this is what it looked like. Clevis bolts have a shoulder on them but not this deep. This could have been a disaster in the making. Thanks Larry!

    This is worth pulling out every year at annual to take a peek at for sure!!

    Tundra tires
    I am getting to the point that I need a new set of tires, and would like to replace with the biggest I can get. What I have are 22x9x8 atv tires with the nubs ground off. I've seen the $100 21x12x8 pair on ebay but would like to get closer to 30" if I could. Does anybody have any experience with tires of such size on a KF? I don't have time to do a big mod job, so would like to stick with the 8" rims. Any pointers?

    Well....I think I am calling my attorney in the morning. Stace said last friday,25 November, that I would get a call a week later...possibly on Saturday that he would be leaving to deliver my kit and another plane. He said it had been long enough. I heard nothing all weekend and have not been able to make contact with anyone out there. Not sure what to make of it from here....I have passed up a few really good deals on flying gone. If anyone out in that area knows something...I would appreciate a heads up. And not taking my calls is not good with me.

    ear ache
    During a commercial airline flight an experienced Air Force Fighter Pilot was seated next to a young mother with a babe in arms. When the baby began crying during the descent for landing, the mother began nursing the infant as discreetly as possible.

    The pilot pretended not to notice, and, upon disembarking, he gallantly offered his assistance to help with the various baby-related items.

    When the young mother expressed her gratitude, the pilot responded, "Gosh, that's a good looking baby, and he sure was hungry!"

    Somewhat embarrassed, the mother explained that her pediatrician said that the time spent on the breast would help alleviate the pressure in the baby's ears.

    The Air Force Pilot sadly shook his head, and in true pilot fashion exclaimed, "HMMM, and all these years, I've been chewing gum."

  10. akflyer added a post in a topic 582 Cruise RPMs   

    I cruise 5800-6000 depending on how fast I wanna get somewhere. Just make sure you have enough pitch in that the EGT's stay around 1150 at straight and level cruise.

    Edit... Love your Avatar! That one has to have you wrapped around her lil finger

  11. C5Engineer added a post in a topic 582 Cruise RPMs   

    I run mine at 5700-5800 for long range cruise. Fuel burn goes up almost a gallon an hour at 6000 with my set up and I only gain 2-3mph. If I'm just out dinking around I'll run at 55-5600 and see around 4.0-4.5 gph.

    I would add a degree of pitch to your prop. If your seeing 6500 on climb out your going to over rev it if you go wide open straight and level. I turn 6300 on take off which gives me around 6500 at WOT straight and level.

  13. BryceKat added a post in a topic 582 Cruise RPMs   

    Hi Randy,
    I have an in-flight adjustable prop on my 582, but when I had a fixed pitch I would cruise at 5800-6000. What I'm most concerned with is keeping egt's less than 1200 so the pistons stay solid and don't melt! Remember, 582's are originally snowmobile and watercraft engines that run at 8500 rpm. I run mine 6800 for take off and add more pitch at 500 agl and set rpm to reduce fuel burn. Have fun, Bryce

    582 Cruise RPMs
    Was wondering what most of you cruise at for RPMs with your 582. Ive got 6.5 hours on my Skyraider now and if the weather holds true for the weekend I want to venture out of the pattern aways.The wind has been blowing so much around here lately that I dont want to get to far from the airport.At full throttle on climb its a tad over 6500 so would 5800 be a comfortable cruise rpm?Thinking about putting a little more pitch in my prop,the climb is unreal,these things are little hotrods,just have to get used to them.

    I have done a few "strafing" runs and more than a few bombing runs in my avid. Its alot easier to drop stuff out when the floats are not on it as I can just release.. I gotta give a good toss to clear the floats. Looks like a great use for the BRS to me!

    A liar.... well.. Truth be told yet again, there is no hard and fast gross weight. If the builder did a little beefing up here and there when he built it, and loaded it up to a 2000# gross during phase 1 and documented that, then you could fly it at 2000.. Not saying that is smart or prudent, but that is legal to do. You as the builder set the gross weight. I am not aware of any factory "gross" weights over the 1200 that Doug mentioned.

  17. akflyer added a post in a topic First flight   

    The numbers look good to me. What does your EGT do at cruise? I run mine on the 3rd clip also and run 165 in the summer and 170 in the winter. Idle screw is spose to be 1.5 turns out for a starting place. If the carbs are not synced you will never get a good smooth idle. The prop pitch is set just perfect as 6500 is the max HP / TQ so you have that dialed in!

    Mine shows 7- 7.2 GPH on the fuel flow WOT so your right where you want to be.

    Mine will idle smooth as a babys butt at 12-1300 all day long, but I have it set at 1650-1800 depending on whether it is cold or not. NO vibration in the airframe at all. Did I mention how much I love the clutch??

    Hi Herman,Glad to see you got it back in the air,does it outperform the Jab? My 582 starts getting rough alittle below 2100,make sure and dont let it rattle and shack on a steady diet because its hard on the gearbox.I had to sync my carbs to get mine to idle right,wish I had a clutch but maybe next year.I have my idle screws backed out one turn and my needle is in the 3rd position from the top.Ive been running 162 main jets through the fall but just put in 165,s but havent tried it with them.Daytime temps are in mid twenties now so had to fatten her up.My EGTs have been running around 1120 give or take,our field elevation is 2120,what is yours? 170 mains seem like alot to have that high of exhaust temps,maybe you are at sea level dont know but 1150 is good according to all the Rotax guys.Im flying mine this weekend if all goes right so I'll let you know what it does with 165,s.Randy

    First flight
    Yesterday I made my first flight with a 582 Bluehead in my Model 2 after removing the the 80 HP Jabiru.
    I sure miss the smooth 800 RPM idle of the Jabiru.
    This #490 Kitfox performs well with this 582.
    The 582 does not smooth out till 2700 RPM so I have some tuning to do.
    I have #55 idle jets and ordered #50.
    How many turns out should the idle screw be?
    How low will these engines idle without shaking the airframe apart?
    I get 6250 RPM full throttle at sea level with the brakes on and it climbs at 6500 RPM.
    With 170 mainjets I am showing 1150 EGT's and 225 CHT's at full throttle climb out.
    The needle is in the 2nd from the richest position.
    It was a 50 degree day and the water temp was 175.
    The fuel flow meter was showing 7 GPH full throttle climb.
    The EGT's seem a little high but would like advice on what all these numbers should be to take good care of this engine.
    Thanks Herman

    When I look at that picture i have the urge to mount that = shaped BRS canister to a quick release under my plane and make a whistling noise as it plummets.

    That being said I think the Avid might a good flour bomber... any thoughts?

  24. DBVZ added a post in a topic To Chute or not to Chute ?   

    I have an Avid, that had the BRS in it when I bought it. Mostly, if I have trouble in flight I plan to land ASAP. In-flight structural failure is very unlikely unless you hit something, but if you did it may save you. The other possible application is for flight over areas without any landing space even for a plane like an Avid or Kitfox that can land almost anywhere. Again, unlikely. I do not plan to take it out. The weight penalty is minor, and I can still fly 2 big adults with full fuel. My wife likes the fact the plane has it, and that is worth something.
