OK I have to add my input to this thread.

I met Keith and his wife many years ago at a fly-in here in Austin TX. At the time I was new to RC and didn't know much about RC engines. After speaking with for awhile and looking at his work I was so convinced I bought two engines on the spot and ordered two of his BME26 engines which he quickly shipped. Over the years I spoke with him several times and purchased several more engines and a Falkon ignition when was carrying their product. I corresponded with him multiple times on these boards and always learned a great deal. I've never had any trouble with any of his products or advice. I still don't see how it was humanly possible for him to keep up with the demands of a finicky public.
Keith is a mechanical genius and a total class act. There is much that manufacturers could learn from him.
