    Did some more work. It has been a pain moving the airplane around with the wings folded, so yesterday I made a towbar. Would have just bought one but the prices are outrageous.
    I also made a tube straightening tool that I've already put to use with excellent results. There are  some pictures of it in use on the airplane and a before and after of the fuselage after straightening. I was able to get the longerons straight and they won't need to be replaced. Two of the truss diagonals have a little kink in them, so I'll have to splice or sleeve them .  Looks like I need 2 6 inch long pieces of tube to fix this one.

    The Rotax 912 mechanical fuel pumps have a 5 year replacement interval so all of the bad pumps "should" have been replaced by now. This airplane is going to get the return line when the engine is re-installed. when I do the install I am going to follow both the Rotax install manual and the Kitfox manual, but in cases of a conflict the Rotax manual will win.
    I was thinking about going to a dual electric pump setup and eliminating the mechanical pump but I see the Rotax pump is only priced like it is silver plated, not gold plated.  I'll probably stick with a electric-mechanical setup, but my experience with electric-electric is good. My Sonerai has electric-electric and has been flawless.  I've got plenty of time to think about it though.

    Yeah I was thinking about an electric pump. Will have to do some research.

    Yep. Speedster it is.

    I also had a chance to get the fabric off the aft fuselage and eye up the truss damage. It isn't as bad as I thought. I think all but 2 tubes can be straightened but maybe 3.  The one picture with the colored lines shows the bent tubes and the green ones are ones that can be straightened, the yellow might be able to be straightened, and the red will probably need to be replaced , or at least the kinked section sleeved.

    Got a second run in today. Ran fantastic. Only issue is that I have the prop pitched too high and could only get 4800 static.  Really really happy.

    That's why I'm good with the $90 (per pair) Nanco 21s.  Might not be as good but they are good enough for me.

    You have to do training for Basic Med and see your family doctor but not an AME.  For operating as a sport pilot there is nothing, except you still need a BFR and can't fly at night.

    Finally got some time to mess with this one and got the Rotax 912 running today.  I know the guy this airplane used to belong to and it was a afternoon flight in late August last year when the engine quit when he was at about 1,500 ft agl. I didn't really do anything to get it running.  I just ran a hose from the pump inlet to a gas can on the ground, put some run out blades in the prop hub and it started pretty much right away.  The only things are:
    1. The temp and dew point (23/15 deg C) are right in the middle of the "moderate icing at cruise power"/"Serious icing at descent power", so I guess it is possible it was carb ice, but this Kitfox has the short filters back at the firewall which everyone say are not ice prone. I guess the reasoning is that with the carbs back there they are drawing in warm air from inside the cowl.  I wonder about that theory though.
    2. The other thing I notice is that this airplane doesn't have a fuel return line as called for by this Rotax Safety Notice.  I wonder if this could have been a case of vapor lock.
    Anyway, I'm happy it runs and for the price I paid I'm really happy. To let the cat out of the bag, I paid $5100 for the whole airplane and it looks like the only real problem is the little kink in the fuselage. It has a newish Garmin SL40 comm radio, a Terra transponder with encoder, and a flightcom intercom. I figure those are worth about $1500 all together.

    I've actually almost bought one a while back and should have. I have a son who has CP and is in a wheelchair. BTW, today is actually National Cerebral Palsy Awareness Day. Anyway, when he was little I would ride him in front of me on the sled but he got big enough that I couldn't handle him that way anymore. His lack of balance and muscle control wouldn't allow him to ride behind even on our 2-up unless strapped in, which I wasn't comfortable with.  So he hasn't been on a sled for 6 or 7 years. Below is a picture of him and me in 2010 when he was 15 years old. He's holding on to the bars because he would fall over if he didn't. I would love to get him back out there and I got over what people think of me a long time ago.

    Oh.  I'm also taking my wfe's car to the dealer today. we will probably get carry out from our favorite BBQ joint over there, and we have to get a normal amount of groceries today.  That's what an Illinois lockdown is like.

    Illinois is just under a "stay at home" order from our dip$##T governor.  Basically, he hasn't declared martial law, so it is really only a recommendation from his office. It is his office telling people to stay home as a way of forced social distancing. 
    I've made 2 trips to empty my father's house in lower Michigan since the order took place. Drove from my house to my father's empty house with zero people in it, loaded up and drove home. Repeat.  Only stopped for gas using a credit card at the pump.  You can still practice social distancing and do what you need to do if you aren't an idiot.

    Yeah. When I'm done it will be setup for left seat flight primarily, but will have enough that right seat flight would be easy too. Main thing for me would be switches easy enough to reach from both sides. I can still remember doing solo right seat practice  for my CFI and having to lean way over from the right seat  in the C152 to reach the switches. I'll probably have a home brew digital ASI/Altimeter/Tachometer on the right for convenience but not really necessary.

    Most I've seen lately install like a pitot. Here are a couple examples, Garmin and Dynon.

    Another Kitfox IV rebuild project
    So I finally got a chance to get my project airplane home today. This is a Kitfox IV speedster powered by a 80 hp Rotax 912 UL that I bought from an insurance auction. It actually belonged to an acquaintance of mine and was located only about 30 minutes away. The airplane suffered a loss of engine power followed by a forced landing to a waist high bean field, which ended in a rapid nose-over.  The vertical tail struck the ground and the aft fuselage got bent as did the vertical stab. The horizontal and elevator look OK as do the wings and struts. The plan is to rebuild the airplane while incorporating a few key modifications which will include these main mods but also a lot of little weigh next to nothing mods:

    1. Landing gear area reinforcement
    2. Tail spring mount reinforcement
    3. Fuselage widening (Murle Williams style)
    4. Provisions for future autopilot servo mounting
    5. Upgraded panel with only engine monitor, Garmin G5X, tablet computer for navigation, intercom, radio, and transponder.
    6. Upgraded baggage area.
    It will probably be a little while before I can really get into it as I have to clean out and sell my father's house since he passed away recently. He was a pilot too and I had wanted to get him airborne in the other Kitfox I have but his health never got well enough. I know he would have also loved to see the rebuild of this project airplane.  I learned most of what I know about fabrication, welding, machining, and general mechanicing from him.
    Anyway, Here are some pics of it stuffed away in the storage part of my barn.
