    Kitfox flaperon position question
    Hoping someone with a Kitfox 4 or later can provide some dimensions. I am building a Kitfox(ish) wing for my C model Avid and feel the position of the flaperon is critical for proper control response. I have attached a drawing with 4 dimensions for the position of the flaperon relative to the trailing edge of the wing. Any assistance would be appreciated.

    That is very heavy.  Would almost wonder about your scales.  Rotax says one should wipe the floats off, and let them air dry for a couple of minutes before you weigh them.  Bing says it sells only for motorcycles on their website, but I've bought from them and used these floats in my 912.  I've always been tempted to try the white single piece floats they show, my type 94 on my Jabiur engine had that float from Jabiru, and it worked fine for 20 years.  At least it looked to be the same looking at the pictures.  Like I said, I've been tempted to try, but haven't.  JImChuk
    PS,  Leading edge airfoils, and Lockwood aviation sell them as well for more money I believe.

    Jim,
    One pair is 10g and the other 11g. I got Fat floats.  Any recommendations on who to get them from? Thanks, Bryce

    I noticed a post of a new owner on Rotax Owner with starting issues and a few years back I experienced some worth noting. This happened on a trip to Idaho after fueling and running on 100 LL.  ABOUT THE SECOND FUEL up the 912 would not fire at all. Finally changed out the plugs and it fired right up.  The fellow with me fueled at all the same places had no issues at all. The next time I stopped same issue. Running short of spare plug I found I could change one plug and the engine would start and run just fine.  Once I returned home and running on auto fuel, 91 alcohol free, no more issues.  To this day I do not know what was the cause but suspect some chemical related issue with the lead in the combustion chamber related to temperature of the burn.  Anybody else ever have this issue. I was not running Iridium plugs at the time.

    My NR hubs do use drive lugs.  They are not threaded, but rather have a 5/16"/8mm hole through them.  I think the bolts where the deformation shows were not tightening up correctly or enough.  Even though the torque wrench said they were tight enough.  Might be that the galvanizing (if there is any) was being squeezed off the bolt threads and galling and binding up.   
     
    PS   When I submitted my first post on this topic, I put the pictures in the order I wanted them to be in, and wrote my description accordingly.  Just looked now and they are not in the correct order.   Picture one and three are the 80 HP with about 175 hrs run time, pictures to and four are the 100 HP with about 15 minutes run time.

    I have ran quality 8.8 metric bolts in my props for the 912 engines without issues.  I suspect that the bolts may be counterfeit and of poor quality.  Looking at the hub there seems to be deformation where in contact with the washer’s perhaps it is just the pictures.  I guess I would need to hear about the report on the recent KF crash in AZ where there has been some doubt cast on the prop.  These of course are just my thoughts from looking at pictures which doesn’t mean much.  I do wonder what grade of aluminum is used in the hub.  Does the hub use the standard Rotax drive lugs? Mine are threaded for the 8.8 x8mm bolts but I know they are available clean bored to be used with nuts on the rear.

    8.8 is similar to SAE grade 5, which is comparable what AN hardware is.

    The bolts have an 8.8 marking on the heads.  JImChuk

    I'll take a look for any head markings on the NR bolts.  I did replace them with AN5-36 bolts, so shouldn't have any issue with bolts going forward.  I'll have to change the clamp bolts out as well.  JImChuk

    So what markings are on the heads of those socket head bolts? From what I've read online they are supposed to be made to a better tensile standard then grade 8.
    They are supposed to be on par with ISO metric standard of 12.9 or better which makes them a cut above grade 8.

    NR prop bolts concern
    Hi all,  I have about 175 hrs on my NR two blade prop on my Kitfox 4 with 80 HP 912.  I've adjusted the prop a number of times between winter and summer, but never actually took the bolts out.  The other day I put a balance master on it, and got new AN5 bolts for the install.  Here is what I found.  I've always torqued the bolts to correct torque, but a few times it did seem like a couple of them acted weird.  Like not turning as much as I expected at the next torque setting.  I would say that apparently, they weren't tightening up to correct torque, at least some of them.  I'm back to working on my new built Kitfox 4 now, and I took the NR two blade prop off of it, so I could work on the engine and cowl install better.  I had ran this engine/prop about 15 or 20 minutes last summer, before I got side tracked.  Both times I used the bolts that NR supplied with the props.  Last prop I know of that came from them didn't come with bolts.  Maybe I'm not the only one who had an issue.  I like the prop, gives good performance, but if you are running their bolts, you may want to have a look.  First and third pictures are the 80 HP, the number two and four are from the 100 HP 912 with 15 or 20 minutes run time.  JImChuk

    New set of dolly wheels for the skis
    Recently I saw someone had made dolly wheels with two wheels and it looked like a good idea to me.  My single wheel ones sagged to one side and weren't the best.  Made a set of the duel wheel ones and finished them today.  Much better.  Pull the one 1/4" bolt and they come off.  They are a bit wider than needed for these skis, but I may make another set of skis, and they will be a bit wider.  JImChuk   
    PS  not sure how this ended up in the close calls and dumb stunts the first time.  Moved it now and will try to delete the other post.

    I've flown on wheels with 4 or 5" of snow.  Heavy wet snow would be worse than light fluffy stuff of course.  Skinny tires will cut through the snow better than wide ones.  Try for three point full stall landings as well.  Don't wheel land it.

    When to put skis on
    My Northern Friends,
    How deep does snow have to be before putting on the snow skis? Diva has the big Aero Classics on her, but I don’t want to find out the hard way

    Jim. I don't think my plane has any of the upgrades you mentioned. I'll try to get a look at it in the next couple days. I know it doesn't have the rudder pedal mods for instance.

    I built those skis myself.  I have a sketch somewhere that I was making and never completely finished.  Some one else was asking about it the other day, and I couldn't find it.  Here is a post I started a few years ago.  JImChuk

    Jim, I'm jealous. Not that I have a lot of use for skis, but I am curious if those are production pieces or did you make them? If you made them are they plans you could share or are they in your brain?

    The heavy hauler wing has two ribs between the ribs with the long tailed ribs that the flaperon hinges on.  The STOL wing has only one rib between the long tailed ribs.
