REFLECTOR: new electronic ign.

[Ronnie Brown]

Keith,

I'm sorry that wasn't very nice of me, I didn't mean to step on toes.

Just my opinion - everybody's got one, most of them stink!!!

I think Honda has already joined forces with Continental to build a flat
four, water cooled engine.  See half way down the page of
http://world.honda.com/AircraftEngines/

| Ronnie,
|
| Yeah, but I went with the LASAR in part on the recommendation of the guys
at
| Lycon.  If you ask around enough, it's possible to find any given opinion
on
| any component.  In the end we all have to "pay our money and take our
| chances"!!  If it doesn't work out, I'll let you know!
|
| I'm really waiting for someone like Honda to get serious about piston
| engines for GA aircraft.  It looks like they are moving forward with their
| jet, and I'm betting that they will be a major force in piston engines
| within a few years.  If they do decide to go after the market, both
Lycoming
| and Continental are liable to be crushed.  The old-line companies are
really
| sitting ducks when it comes to engine and manufacturing technology.
