      Ellery, if I understand correctly the "warp drive Prop that you had trouble
       with was made by a company that doesn't exist anymore, in fact taken over 
      or purchased by Daryl, the current warp drive manufacturer. Is that correct
      ? I am a bit confused, in that I have a Warp Drive prop from Daryl that I r
      ecently managed to send a hefty pair of side cutters through, and it didn't
       even leave a mark on the blades. I know that they went through them, becau
      se they hit the roof of my hanger and that is 15 feet off the ground.
      
      If my information is correct and Daryl had nothing to do with the manufactu
      re of your defective prop, fairness would require me to differentiate betwe
      en the two when a discussion of Warp drive props was mentioned.

      I have 3,000+ hours on Warp Drive solid carbon fiber blades over the last 1
      8 years.  Never had any kind of problem with WD products, even after sendin
      g exhaust pipes, bolts, etc., through them.
      
      Believe we determined recently the Warp Drive blades Ellery was using at th
      e time of their failure were probably first generation cored blades built b
      y the initial Warp Drive Company.  Daryl has been the owner/manager of WD f
      or more than 20 years.  His company, the second generation company, has onl
      y produced solid carbon fiber blades.  WD is a big producer of solid carbon
       fiber blades for the airboat industry, using the same technique to build  
      them as the UL/light plane community blades.  Some of those six blade WD pr
      ops are being turned by 350/454 Chevy's, 6 cylinder aircraft engines, and o
      ther high powered exotic hot rod airboat engines.  I am sure none of the ai
      r boat gang are using cored WD blades.
      
      I have also flown factory Kolbs with IVO props.  They performed well.  Only
       problem I can remember was the SS tape pulling loose and cutting my finger
      s trying to repair and replace.
      
      Remember seeing Ivo walking around Sun and Fun many, many years ago with an
       IVO prop over his shoulder.  That was his first visit to Lakeland, with hi
      s prop.  He was trying to generate interest to get his prop shop up and run
      ning.  Cannot remember what year that was, but probably mid-80's.

      Seems like I read that the real hard bolts aren't recommended for prop
      bolts because they are a bit brittle. My prop hub (PowerFin) requires a
      much lower torque rating than the softer SAE 5 bolts can handle anyway so
      that is what I use.
      
      Also I use a standard nut on my prop bolts so that I can get accurate
      torque settings. My prop flange isn't threaded. Then I put a nylock nut on
      as a lock nut.

| Subject:  | Some things to check before covering the fuselage pod | 
      
      After spending over an hour removing two screws and getting a sore back in
      the process, I thought I'd offer this to any builders out there.
      Before you cover the fuselage, assuming of course that you've installed all
      the goodies in the fuselage first, check to be sure that all the fasteners
      are accessible with ordinary hand tools. Mk III builders of both kinds,
      check how hard it is to get at things when your only access is through the
      door frames. Check to see that all those nylon ties are trimmed to
      eliminate any sharp ends (see photo of what happens when they're not)
      Basically, think maintenance. How will you get to any item in the pod to
      check, lubricate, or replace it as required. Believe me, spending an hour
      to remove two screws that were installed upside down where there isn't room
      between the screw head and the fabric covering is not fun.
      Okay, back to the hangar to install the new instrument pod pedestal and see
      how much weight was saved by taking out the solid wood console.

      Sounds as though you are concerned about compromising a lawsuit. Just to be
      clear, I don't get free props from Warp either, but I did get what I paid
      for and that was a damn good strong prop for my airplane. I don't have an
      axe to grind in any of this, just wanted some clarification since what was
      called a Warp drive by you, didn't match with what I have on my plane.

      Hi Rick
      I looked into the "hardness issue some while ago". The bolts are not "brittle"
      they are stronger in tensile sheer and tension. Its the same with grade 8 bolts
      they are much stronger than 5 which in turn are equivalent to AN bolts, and
      same with grade 10 bolts. The price difference is small so I opt for the stronger
      stuff whenever I can. I agree that in most applications the cheapest bolt
      we can find is more than adequate, but as a matter of personal satisfaction, and
      cheap prop for my ego I spend a few pannies more and buy the stronger ones.
      Hell if I was bigger, better, richer, and better looking maybe I would not want
      to over compensate but it is what it is, or maybe I just like the best quality
      whether I need it or not.  :-)
      
      Here is a table I found by a quick search, I am sure there are better tables out
      there.

      I don't mean to butt into a private conversation, but when I decided to put
      a spacer between my Warp Drive Prop, and my HKS I asked about finding AN
      aircraft bolts for it and someone informed me that the 8.8 bolts were what
      was needed and the harder bolts were not better for the simple reason that
      they were too hard and therefore brittle. I may be wrong, but I believe it
      was Daryl of Warp Drive that told me so.
      For what it is worth!

      Ed:
      The brown should go to ground.  The yellow and the yellow/black should go to the
      input (A/C) to the Key West.  The output (DC) of the Key West would tie into
      whatever you have that requires the 12V DC.  The brown (ground) going to the
      negative side of the output of the KW may have been someone's way of getting the
      engine ground to whatever is being fed by the KW.
      
      For further confusion go to Google and put in "Rotax Wiring Diagram".  It'll make
      your hair hurt.
      
      Your results may vary.

      George,           I was the one who wired my firefly originally and have 
      170 hours on  it.   Do I need to   run    
                                the brown wire from the engine to the airframe?  
      That is the only one in  question. It seems 
                               Crazy at this point, but I may not have had it 
      right ,all along.

      Wow, that's new to me but may be true.  Someone smart one to give 
      them a call and see if this is true and why they may not like the Key 
      West regular.  I've been running one for years, although I do run a battery.

      Yes I have run into this myth several times over the years, it reminds me of the
      over square myth that was a fairly widespread reality back in the 70's. It 
      finally went away, not sure if it was me or that people finally thought about
      it. 
      In any case and the best comparison I can make is the difference between 1100 aluminum
      and 2024 aluminum. Or another away is that by the time you would reach
      the brittle factor between grade 5 and grade 8 the grade 5 has already failed,
      I am too lazy to look for fatigue or brittle factor between the grades but as
      a SWAG I say we would not find much of a difference if any. 
      
      But I would love to be corrected, anytime I learn something factually new I am
      happy.

      I don't mean to butt into a private conversation, but when I decided to put
      a spacer between my Warp Drive Prop, and my HKS I asked about finding AN
      aircraft bolts for it and someone informed me that the 8.8 bolts were what
      was needed and the harder bolts were not better for the simple reason that
      they were too hard and therefore brittle. I may be wrong, but I believe it
      was Daryl of Warp Drive that told me so.
      For what it is worth!
