    Just reviewing the numbers under the Speed Wing Commuter Section provided by Jim - I know Transport Canada will ask me what these things mean exactly, since there are no side labels can someone confirm what I am seeing here and fill in errors and all the ???? or the blanks. Really appreciate the help!
    Length of Aircraft (Nose to tail) - 23ft 11.5 in.
    Wing Area = 97.31 sq ft
    ???? = 42 in
    ???? = 51 in
    ???? = 5.50
    ???? = 9.36 lbs
    ???? = 17ft
    ???? = 17ft
    ???? = 7 ft. 9.5 in
    ???? = 67 in
    Empty Weight = 450 lbs.
    Gross Weight = 911 lbs.
    Usable Weight = 491 lbs
    Fuel Tank Size (single wing tank) = 18 gal
    Fuel burn approximate = 3.5 gal/hr (depends on the engine and rpm setting???)
    Range no reserve = 566 miles (Statute miles I would think not nautical miles)
    Recommended prop??? = 64" ground adjustable (Seems this would depend on the engine?
    Solo - 580 lbs (why only 580 lbs gross weight when solo???????)
    Cruise Speed = 110mph
    Stall Speed = 33 mph
    Never Exceed Speed = 125 mph
    Rate of Climb = 1200 fpm
    ???? = n/a
    Best Rate of climb = 57 mph
    Best Angle of climb = 52 mph
    ???? = 125 ft
    ???? = 250 ft
    ???? = 500 ft
    Service ceiling ???? = 20000 ft (seems odd - unpressurized cabin)
    Dual - 911 lbs gross weight
    Cruise = 110 mph
    Stall Speed = 40 mph
    Never Exceed Speed = 125 mph
    Rate of Climb (850 fpm)
    ???? n/a
    Best Rate of Climb = 60mph
    Best Angle of Climb = 55mph
    ???? = 300 ft
    ???? = 500 ft
    ???? = 600 ft
    Service ceiling??? = 15000 ft (seems odd - unpressurized cabin)

    The Hirth dist and two dealers said the same thing. A 70" two blade is the best prop for that engine. So that issue solved!

  6. skypics added a post in a topic YAMAHA RX-1 (140 HP) install in Kitfox 5   

    What is the weight of the Yamaha? 
    If too heavy (200+) you will most likely need to balance out with weight on the tail.
    A friend put a Subaru on his MK4 and had to add weight at the tail wheel to prevent it from being too nose heavy.

    No they did not. The axles on my Mark IV are 2.5 inches longer on the outside than needed and both ends have cut threads in them. I'm sure I will have to make something up but I have axle material and a lathe.

    Gross weight increase Kitfox IV 1050-1200
    Does anyone have the instruction and pictures (both rod through carry through tube and strap between strut attach points) of the Kitfox modification from 1050-1200 for float operation?
    The reason for asking is that I intend to operate the plane on floats and would like to make it as rigid as possible, not to exceed the gross weight limit.

    The way I read it, the capacitor created the minimum load necessary for the rectifier to properly regulate the voltage without a battery. With no load, it tests at about 11.6 volts. It burned out my new strobe without a single flash, so something is not right. The capacitor is properly connected. 
    My wing tanks are in transit. I’m excited to get them in, but I’m going to wait and check the weight without them before installing. 
    Still no registration. It has now been nine months, and I’m tired of waiting. They did cash my check. I hope that means something.
    I have very little left to do. I wanted to do something different with the quarter windows. Maybe plexiglas. 
    In the meantime, my job is getting really busy again, working twelve hours and driving two. The first Copper River opening is tomorrow, and we’ll be buying fish in Cook Inlet next month, which keeps me pretty busy until September. 
    I haven’t gotten a strip cleared out yet. I have a D7 torn apart in the yard, which is where it begins. But... I did get a lot on a grass strip near where I work in Kenai, which will be awesome. Less driving, more flying. And yes, yet another project to keep me busy.

    I suppose it all depends on where the power curve comes in.  I guess I would follow his recommendations.  JImChuk

    I just talked to him and we was comparing the 55 HP 3202 to the 65 HP 3203 engine. The 3202 is more torque than the 65hp and can handle at least 4 deg more pitch than the 65 can. Most 3202 55 HP engines are running at least 15 deg of pitch and pushing static redline. The 65HP engine might be a tad over rated in the HP range. But its a gamble I'll have to take. He has always been straight with me for 9 years that I have been dealing with him.

    Well the Hirth dealer should know his engines.  Like he said, you can always cut it down.   Big difference between the square tip and the taper tip though which maybe should be considered.  The square tip is about 3" wide at the end, the taper tip is about 1 1/2" wide.  Lots of extra surface with the square tip to push against the air.  JImChuk

    My Hirth dealer just E-mailed me and said a 70" 2 blade would work really well since the Hirth 55 HP engine puts out enough torque to turn it. He did say I could always cut it down to 68" if necessary. Which still poses more questions than answers.

    What would you advise? I am an A&P, not a prop guy. My experience with props are strictly FAA regulated.  I don't really know what or how a 66" or 68" would perform with 55 hp. I do think a 70" could be a little too much prop for the Hirth. Wonder what the 503 Kitfoxes and Avid's ran? Maybe a call to Warp Drive would provide some answers?

    Before and after
    I've already posted the dumb stunt but for those who haven't read that post I left the wings folded while unloading my model 1 off the trailer and the tailwheel jumped the track and the rear fuselage smacked down hard on the trailer frame and bent the lower longeron and even got the top one a little. So here's the after the accident but before the fix: and here's the after:

    And here's me and the magician that did it:he managed to straighten both bent tubes with a slide hammer. I meant to have him show me the tool and technique but we were busy with other stuff. The guy is 85 and a true artist with a welder and body work too apparently since that's where he got the slide hammer. The accident ripped the fabric at the lower longeron  and he cut the slit you see at the top longeron but otherwise didn't do any other damage to the fabric fixing it. Until recently he did most of the welding for matco. It's irritating him tremendously that age is finally catching up with him. But he can still get an incredible amount done in a short time. Without him my bird probably wouldn't fly for a couple more years.

    I think 70" would be to long on the 55 HP.  I ran that on a 582 with 2.58 ratio.  If you have to much prop, it may make more drag then pull cause you will have to run it so flat to make the RPM.  If I remember right, Joey and John before him ran a 70" square tip warp on the 582 with C box at 2.62 ratio.  Worked good for them.  My takeoff roll was much reduced with the two blade.  You mention 100', and that might be about what it was, but if we're are talking maybe 300' and 200'.  That's a 1/3 improvement.  JImChuk

    I measured everything today and can run a 70" max dia. prop, but will 55HP handle it is the question. A 2 blade standard hub WD from AS&S is around 485.00.  I might consider getting one to test and experiment with till I know from the results. I am not surprised that the 2 blade performed better on your model 1. A lot of factors come into play with props on different engines, airframes and ratios. I like the looks of a 2 blade better. I am curious about T/O performance of 2 vs. 3 blades difference. Anything less than 100' difference is not an issue since weight, pilot ability and technique can easily add 100' on any aircraft or remove it.  And if a 100' makes the difference of ending up in the trees or weeds, then I probably shouldn't have been there to start with or should have been in a helicopter.

    Whenever I've had to tote mine anywhere I borrow my buddy's race car trailer. It has a big air dam up front that really helps. Drug it from southern Washington to southern Oregon with no issues.
