There exists a Spratt forum on Yahoo. Some info gathered there. Plus there is a Spratt 103 site maintained by the Spratt 103 designer. I have read everything about it I can find. Plans aren't released yet. Supposed to be before the year is out, but who knows? Anything can happen. Bernard Geffray (the designer/builder) recently had a mishap while testing various esoteric permutations. Think he is exploring the extremes of the design so folks like me don't have to. I am also interested in this design.

Hi: I was recently informed by Bernard Geffray the designer iof the Spratt103 that he had installed a set of grooves in the Briggs& Stratton engine he is powering the Spratt103 with. For information on Grooves go to www.somender-singh.com My friend Sing holds a US Patent on the Grooves cyclinder head modification.
Sing was the first trike builder flier in his State in India with over 1500 flying hours. His trike has a Rotax 503 engine with Grooves which flies as no other Rotax can. I introduced my two friends' As soon as Bernard gives me the results I will pass them on to this form.
