    Does it have an electric starter?

    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.

    Also ribs are 18" center on speedwing, 12" center on aerobat.  Both use the flat bottomed rib style. JImChuk

    Bungee diameter?
    I am going to go to cub style gear with a cabane on my C model. What diameter bungee do I need 4 6 8 or 10 mm?  How many feet do I need?

    The Aerobat wing is the same as the Speedwing but with thicker wall tube spars and larger diameter lift struts. Here in the United Kingdom the gross weight is 911 lbs which on the Aerobat can be increased to 1020 lbs if stiffeners are fitted to horizontal and vertical tail surfaces.

    Be most appreciated if you find that page. It looks like gross is 911 lbs, empty is 491 lbs. However I don't know if the aerobat wing is the same as the speed wing, or if it is a different wing all together. That pics shows a trike gear. Essentially I will need some sort of documentation to go back to Transport Canada airworthiness inspector with.

  19. wolves200 added a post in a topic Avid STOL airfoil -some calculations   

    I have a very short airstrip, so short you can´t call it airstrip, just a patch of grass, my take off technic works pretty fine, standing still, WOT, no flaps, start ground roll until I reach 35Kt full flaps and it will jump in the air shorter than starting the ground roll with flaps; conversely when I coming in for landing as slow as I can full flaps; touch down at 37kt (I´m heavy @$$pilot) kill the flaps and it will stay on the ground; if I leave the flaps on, I will be hoping along until I run out of space.-
    Playing with the flaps does have a good effect on short take off and landings.-
    Though I would love to try the suggested modifications of Riblett on the undercamber to improve cruise speed without sacrificing the take off roll.-

    Got looking a bit more at that info I was referencing last night.  Here it is.  Notice there is an asterisk at speedwing and Commuter.  In the note down on the lower left side of the page (some of the print isn't shown) it says that it can come as a tricycle gear or taildragger.  I would think if you can access that page complete, you may have what you need???  I think I have it somewhere, but didn't find it today when I was looking for it.  Did have the pictures though.  JImChuk

    On my Kitfox 1, I tried a two blade Warp, that same 64" three blade IVO, and a 3 blade 68" IVO.  Not much difference between the two IVOs, but the 2 blade Warp was way better in both climb and cruise at same RPM.  It did have the taper tips, not the square tips.  Don't know how much that helps. That was with a 582 with 2.58 ratio.  Cheapest new Warp 2 blade square tip is now $540.  JImChuk

    I've got a Warp Drive 3 bld HP hub that came with the engine and 60" blades. I was just going to order new blades for the hub. All reports that I can find on props state that 68" 3 blade is about the best for around 2.59/2.58 ratio. Most say the 2 blade gives better cruise and the 3 blade gives better T/O and climb performance.  I'll give Hirth a call and see what they recommend. I like the 2 blade but the 3 does sound quieter and smoother in normal use. Way too expensive for the "gimmie prop" way. As in gimmie that prop over there and I'll try it.

    My buddy that had the A model Avid with the same engine as you had a 3 blade IVO 64", and later went to a 2 blade 66" powerfin.  Had better performance with the powerfin.  I have a pair of LH 66" warp drive blades, but no hub. Warp's cheapest hub is $105.  JImChuk
    PS  3 blade was smoother, but not as efficient as the 2 blade

    Getting ready to order a prop for the Hirth. Considering everything, looking like a 3 blade 68" is the best option for a 2.59/1 gearbox and max 5500 RPM w/55 HP.  Anybody have any pro's or con's to speak of?
