The engine we selected back in '82 was a kfm 107...25 hp at 40 lbs.? You could do a max gross of under 500 lbs with an engine like that. https://sites.google.com/site/mykr2stretch/ https://sites.google.com/site/mykr2stretch/parts-for-sale _______________________________________________ Search the KRnet Archives at http://tugantek.com/archmailv2-kr/search.
