    There's nothing high tech about the reinforcement.

    You just cut triangles from plywood and hysol them onto the openings in the truss. Make note of where the bungees pass through and don't fill in those openings.

    Bandit, my avid isn't going anywhere.. The $450 fuel for 4.3 hrs flying is going to put a dampner on my 180 just for fun time! Holy cripes!

  5. herman pahls added a post in a topic Avid visability   

    The Avid Model C that I measured to find out how the gear placement compared to a Kitfox had an upside down 582 with cheek radiators.
    I now understand why the upside down 582 in an Avid allows the cowl to be lower than a Kitfox for better visability.
    It appears that the  top 4 of the 6 Avid 582 engine mount bolts would come  close to fitting the Kitfox.
    Otherwise the Avid and Kitfox engine mount attachment to the fuselage firewall are not even close to interchanging.
    Without a custom engine mount I will not be lowering my Kitfox cowl for the better Avid visability.

    I measured an Avid Mark 4 and an Avid Model C today and you are correct, the gear attach points on the longerons are almost Identical to within a 1/16" of my Model 2 Kitfox or less and could be adjusted with a file.
    All 3 aircraft are within a 1/2" of axle placement in relation to the leading edge of the wing when the fuselage lower longerons are level as when doing C. of G. calculations.
    Av8r3400 said his friend recently ordered a swept forward gear for his Model C Avid, which according to Trackwelder and my measurements should fit the early Kitfox's that do not have the forward float attach points.
    According to Grove's website, their Avid Mark 4 TD gear costs $300. more and weighs 8 pounds more than a Model 3-4 gear.
    The reason for the increased weight is the extra material needed for the forward swept feature of the gear and that it is 5" instead of 4" wide where it clamps to the attachment brackets.
    Av8r3400 said the Grove gear on his Model 4 increase  his empty weight 12 pounds over the stock bungee gear which I could live with.
    Since my Kitfox would require the swept forward gear, the weight increase would approach 20 pounds which I do not think I can live with.
    Thanks for all the comments to help me come to a conclusion.
     
    Where do I find Steve Winder's posts on how to reinforce the seat-bungee truss?
     
    Thanks  Herman

    Fat Avid weight and balance
     Hi guys, well things are getting closer with my fat avid and i.m just wondering if the datum line and formulas  on it, is like the avid c . I have the manual walking you threw it and have a friend thats did them before but want to make sure the extra 18" in length dont affect  using the avid c method of doing the W & B. Randy if you happen to have any of your numbers handy and get a chance to post them ,that would be appreciated, Thanks Willis

    machining a prov 8 case
    I know that someone has done this so I won't ask if someone has done this so I will ask this question
    about what is involved in this. The case is a prov 8 case the holes is already drilled but not taped are there any more to do to the case other than drill the holes for the correct size and tap them to fit a rotax c box to it? do you have to do anything to the crank [a standard 582 crank]
     
    thanks Bob

  9. BryceKat added a post in a topic Rudder peddle pressure and nose gear from the right seat   

    When mine was a tricycle, I had the same problem. I switched to a taildragger to fix it. However, someone makes a swivel type nose wheel ala an rv-6 for the avid and it works very well. Chris B had one on his mkiv and really liked it. Pm him, he'll help you out. Bryce

    The Kitfox and the Avid gear are not the same, but 5 minutes with a file will make that change, up until model % I believe they are almost identical fuselages, There are several ways to strengthen the seat truss that Steve Winder had described, the easiest is to use an Epoxy ( he used Hysol 4130 I believe as hat is what Kitfox sells) and glue little triangles into the seat truss. If I was doing a complete teardown I might think about welding in 4130 plate, nothing any bigger than .062.

    Rudder peddle pressure and nose gear from the right seat
    Flying right seat brings out a couple of problems with the rudder forces, left peddle to nose gear linkage, and nose gear centering springs.  The rudder pressure through the peddles seems excessive and seems to center around the springs for centering the nose gear – which are “very stiffâ€.   Any thoughts or cures to this problem?  Left seat has the problem also, but it’s not as noticeable since the nose gear linkage doesn’t encroach on the rudder peddles – giving more space on the peddles for your feet.

    Chase,Sounds like your ASI was very accurate at that speed - Airspeed almost never matches GPS groundspeed anyway. Good cruise.

    Folks, thanks for the introductory advice.  I have my Beech Sundowner up for sale and am looking for the KitFox 4 or 5.  One, KitFox 5,  just popped up today on Barnstormers with a Lycoming O-235 engine @$39K.  200 hundred hours, with all white exterior paint in Denver.  Based on your experiences, does that sound like a good combination and a reasonable asking price?  Mark

  18. C5Engineer added a post in a topic Hi, I'm new to Avid Fox Flyers, looking for info and a plane   

    Welcome to Avid Fox Flyers!
     
    The first question you have to ask yourself is what is your mission? Are you wanting to just unload a plane on the side of the road and go check something out while traveling or will you also be using is as your primary plane at home as well?
     
    A 912 powered Model IV cruises at 115 ish and is a bit bigger and more refined than the earlier models. They also fetch an almost double the price tag to an early, simple, two stroke powered one.
     
    I would say steer clear from a Kitfox I or Avid A model. They were very basic machines. A lightweight 2-stroke powered Kitfox or Avid would be perfect for hauling in a trailer and unloading on the side of the road to go and do some airborne sightseeing. Performance and visibility is amazing. The downside is if you are planning on doing crossing country stuff they have a realistic cruising speed of 80 mph.
     
    Here's some basic info to consider while looking for a bird.
     
    Avid models: B, C, Mark IV
    Kitfox models  2, 3, 4 The Kitfox 2 and 3 were similiar to an Avid B and C but the Kitox 4 is a totally different machine than an Avid 4. The major difference is the Kitfox 4 used the Riblett Airfoil and a different control system.
     
    Avid wings are either STOL (undercambered airfoil) or Speed (flat bottom) The speedwing is unpopular unless it's been extended by 2 rib bays.
    On Avids a 582 is about your best match to the airframe for STOL ops. They fly great with Subaru motors too but unless the fuse has been extended they tend to be very nose heavy and they won't get off the ground nearly as quick as a two stroke powered one. If you are ready to drop 30K one one a 912 powered Kitfox 4 like Larry mentioned is the nicest of the bunch. They are in high demand and good ones sell very quickly off Barnstormers. A 582 powered earlier model is running in the mid teens right now.
     
    If I were towing one around the country I would go for as light and simple as possible but that's just me. I have a friend who does this. He has an Avid to tow behind his motorhome. A Zenith CH601 is his everyday flying machine and a Tripacer for when he goes camping with his wife and dogs. And he lives at an airpark 100 yards from the runway. Living the dream.
     
    Stick around on here and don't be afraid to ask questions. The goal of this site is to be a one stop shop for all things Avid and Kitfox.

    Almost twice the displacement without much weight gain, good thinking on the shared aircleaner, wet sump lubrication with PSRU lubricated by engine oil.  Overhead cam rather than pushrod.  I'm guessing that it actually makes it's horsepower while HKS usually mostly disappoints in that regard.  I wonder how much?  If you look at the power/torque curves it's really peaky.  Like a 2 stroke.

    No snow yet. I went out today and put a couple more hours on her. On the west side the snow line was around 2000' and the ponds above 1500 were starting to freeze up. It's no avid when it comes to getting in or out, but after 6 or 8 splash n dashes with a 10,000 hr 180 time driver copilot, I learned a few techniques that cut my take off run to about 1/3 of what it was. It's an amazing bird in the hands of a good stick! Much of what we went over was already stuff I knew, just tweaked it a touch to what the plane really likes. Damn, I got spoiled with the control forces on an avid when I thought I had the yoke all the way back to get it on step, I still had 3" more to pull. Thought I was gonna pull the damn firewall out!

    $.02 worth of advise: Hold out for a 912 powered Kitfox IV or newer.

    The design had matured by then to a great little plane and you will not find a better engine for the type than a 912. From there look for the doo-dads you would prefer.

    Your budget may dictate other tid bits of advise.

    Hi, I'm new to Avid Fox Flyers, looking for info and a plane
    Hi, I hope I am in the right section. I have been flying for 30 years in Cessna and Baby Beech products.  I would like to migrate to an Avid or KitFox that I can fold into a covered trailer and haul around the country to drive-n-fly.  I am curious about engines and airframe models.  It looks like this group knows a lot about both.
