    I'm seriously considering trying to find some type of squirrel cage fan to use.  I'm not happy with the dual 4" computer fans.  They do not move enough air through the exchange to heat the cabin sufficiently, IMO.

    You should be able to purchase an RV6A assembly (the one of your pics with the unfinished wheel pant). That's what I have on mine (including Avid drawings for same). I'm planning on taking mine off later this year to install Grove taildragger gear I purchased. Thought about selling it but I'm kinda thinking of hanging on to it as a boost should I sell in the future when the Bearhawk is done. Although I'm really falling in love with this bird. Thinking about the possibility of the enclosed trailer route for retirement ( or pre-retirement) travels... 
     
    As Ed mentioned, it also provides stabilizing compared to the original style Avid nose gear as it puts the wheel farther forward.

    Like the Flyer, the Catalina is a testament to a great Dean Wilson design.

    I absolutely agree about the Seamax being great. The only thing on my my avid catalina I prefer compared to the Seamax is the really big luggage compartment (or child seat). There is hardly any space in the Seamax.
    Besides the cruise speed (90 vs 115 Mph) the Catalina and Seamax are nearly identical in performance. Obviously the folding wing Seamax is still WAY..to expensive (for me at least) at 150'000 USD (2012) a second hand one not below 95-125'000.....A nicely built Catalina with 912s will end up around 35-45'000   
    In my opinion the A5 is a hyped up rich man's heavy toy. The usefull load is small, empty/gross weight too high and rate of climb pathetic (a very well hidden secret number). Another secret is the relatively high stall speed at gross (45-52 Mph vs 37 Mph for Cat/Seam.)...Water take off at gross is crazy long...
    1510Lbs gross for a 100Hp..........really not good weight to power ratio compared to Seamax and Catalina (15,1 vs 12 Lbs/Hp)

    Unless you can find one on Barnstormers or some site, I guess Kitfox would be the only place to buy one?  They were $1500 the last I heard.  I made mine with Walmart mountain bike parts I got out of a trash bin!   ;<)  It is not finished or tested - I still need to weld the side support tubes on it.  EdMO

    Mark - I had a thread about the different cowl/582 engine mount differences a while back on the TKF forum. If you are registered you might find the info and pics helpful. LINK
    Also, you can see the different KF engine mount p/n's (and all other part #'s too) listed on the Packing Lists from the KF3 and KF4-1050 kits I listed in the Classifieds HERE . Attached is a quick screen shot from the KF3 records.

    Icon is a scam, I think the SeaMax Amphib with folding wing option is the best bang for the buck now.

    Your Post was put in the wrong category, but I will answer it anyway - Maybe an administrator can move these?
    "Are there any issues moving the front portion of the three wheel base rear a bit?  Stability?"
    I have some info about that in one of my books - the more angle from main to nosewheel, the more chance of flipping over to one side - in other words, the shorter the triangle from mains to nosewheel, the less stabile it will be.   The Avid is an already short triangle, so you don't want to shorten it more.   The Kitfox / RV / Grumman type nose gear puts the castering wheel farther forward than the original Avid.   EDMO

    Shame all the Photobucket pics were lost. Sure wish folks would just post a copy here rather than link offsite, not that hard.

    Castering Nose Wheel
    Hi,
    I'm looking for leads to acquire a catering nose wheel assembly for my Avid Flyer Speedwing.  Just getting tired of the tied rod steering assembly and the pivoting nose wheel seems unstable, is prone to shimmy, and like to try to turn 180 during taxi.  Also concerned about the feedback forced into the pedal assembly.
     
    The first two pics is my current set up. before and after the assembly snapped after three hours of flying.
     
    The next set of pics is what I am looking for.  I'm sure if I could get the wheel assemble, having a local welder put it on my nose tube would be easy.
    Where can I find this assembly?
    Does anyone have any experience or tips on a trailing link castering nose wheel?
    Are there any issues moving the front portion of the three wheel base rear a bit?  Stability?
     
    Here are the specs on the steering tie rod (that broke) and nose tube:
    Push-Pull Tube Part # from Avid:
    CLG 21  Forked Connector for nosegay steering
    CLG 20  Push-Pull tube for nose gear steering
     
    Bolt through nose wheel tube: AN4-27, or 1/4”,2 drilled end with castle nut and pin
     
    Push-pull rod =  0.37” thick, 5” long, 7.5” eye to eye on ball sockets
     
    Ball sockets = AN3 or 3/16” bolt or .1875
     
    Nose wheel tube =  1 3/8” or 35.08mm thick

    My CFI DRILLED these things into my head. I’ve only got about 50hrs on the log so I’m still WAY green. I actually put together a trng flight plan when I go up. So I hit, slow flight, stalls (still freak me out a hair), turns around a point and split S (all the ground reference stuff)

    Another option might be to also look at if those side cowling tubes even need to be there.  I know the Model III and later did away with them, though dont know if there were any modifications to the fiberglass for added support.

  19. nlappos added a post in a topic Bush gear failures   

    I just bought the gear from Lowell a few days ago. We exchanged emails about it and he knows it works, and that it is strong, but how can he control folks who land off site?  As I said above the gear is quite strong enough for landings at 8 to 10 feet per second. As an indicator of how hard that is, the max landing at 8 feet per second is a 4 G landing while not damaging the gear. In a UH-1 helicopter, 8 feet per second (480 feet per minute) will spread the skids and make the belly touch the ground.

    The best heaters I’ve seen are in cabin heat exchangers with computer fans on them. A 1/2 line that is T-d into the main line feeds them.

    Engine cooling
    My model c has the belly radiator and no provision for cabin heat.  There apparently have been several arrangements for in-cowl radiators.  The one that I currently favor has one radiator mounted behind the starboard-side motor mount strut.  This allows a  simple radiator mount, along with a very neat setup for cabin heat - just a little valve-box/dump on the firewall.  But man, that rad is darn close to the firewall!  Does anybody have this arrangement, and how well does it work?  What are the specs for the radiator?  It's clear to me that a good in-cowl arrangement will save drag and fuel over the belly rad.  I'm also thinking that instead of a fixed gill to exhaust the hot air out the bottom, a sort -of  variable cowl flap could reduce cruise drag while allowing for lots ot airflow for climb.  Of course it would likely make removing the cowl kind of a pain.  Gotta work on that.  I'm not too keen on the dual-rad-in-nostrils approach.  Vibration, and so many opportunities for leaks.

    I assume you are using the shorter (unmodified elbow) as the extended one wouldn't work for your application.
     If able let me know what two lengths you have and I will try to confirm on a local model II
