  Dave Lemon,

  You might be interested in this super simple turbo installation
  on a one rotor engine. Owned by Randy Lewis in the Simi Valley.

  BTW there is a huge interest out there in an all aluminum one
  rotor with or with out turbo. People bug me once a month about
  a rotary LSA engine for the last five years.

  Jeff can make the shafts and counter
  weights if you order a few. Since you have a bunch of E-shafts
  just sitting on the shelf for the last ten years these can be
  converted to one rotor version rather cheaply.

  This engine would fit the new Light Sport Aircraft class.
  All you need to fly one is a drivers license. Google it.

  The only engines available  now are the Rotax and Continental
  O-200 which are only 100 HP and cost $20,000 each.
  You could easily get $15,000 for this 1 rotor with a gear box.

  We have a new super simple gear box and prop flange design.
  Ed Carver and I are building prototypes now. Uses low cost Ford
  C6 auto tranny planetary gears. There are hundreds of
  similar Ford C6 based gear boxes flying now with 2 rotors.

  Or you could use a cog belt like Randy's engine.

  A Holley 2 barrel carb with leaning kit would work fine. Ignition
  is super simple using 2 RX8 coils and one hall effect
  sensor firing both plugs at 22 fixed degrees BTDC.

  The titanium rotor would really pay off in weight reduction
  as the weight saving is doubled due to the lighter weight
  needed counter weights.

  BTW Dave, it is in the tradition in engine development history
  to use a one cylinder test engine.  It is quicker to take it
  apart and put it back together. I suggest the same thing
  for your titanium rotor development. Build a one rotor test
  engine.

  One item you mentioned below needs some clarification.
  The RX8 coil can not be used in a simple ignition as implied, because of
  the
  2ms dwell time required. The trigger is at the rising edge of a 2ms square
  wave, and coil firing is at the falling edge. This will give you a 90deg.
  retarded ignition at 7500RPM.
  I believe we talked about that already a few years back.

  I would be nice, if someone came up with a simple electronic setup,
  without
  a microprocessor, taking care of that.

  Real easy to do that Richard with a 555. It is called
  a non-retriggerable one shot.

  I would seriously be interested in how that works. I could not figure it
  out.

 After thinking about is some more the single chip computer
 may be the cheapest solution.

 The computer in Henry's $10 tach does half the job already.

Paul,

Here are a couple updated photos.  i dumped about 25 lbs from my redrive.
