RE: CH Ignitions
I know that most people who fly RC model gas engines do not know this but bill is the pioneer of RC ignitions for RC gas engines, I am sure that somewhere along the line somebody else might have done it but he was the first, A few years back if you flew a RC gas engine it had his ignition on it.
It is so good that one of the best ignitions out of China is manufactured form it.
I have converted a lot of chain saw engine in the past as well as others using his ignition and never had a problem with them,
I do not know how bad his health is but Bill here is hopping a speedy recovery and hope you have long time to enjoy the later years in your life.
