- Brace yourself!!! 2-cycle pipes and coupler material

[Woodward James R Civ 416 FLTS/TPS]

Despite two minor crashes, and a "accidental" competitor induced stab total
break-out, I've managed to keep my prototype together!  I have Ken Blackwell
(who also is on the list) to sincerely thank for his trust many months ago,
regarding his design and my involvement with it.

Hey, how come you have a Phase One, and I was told they are not 
available till spring?
