RE: Which is better OS .91 or Jett .90 and for that?
Just got back from a club race. My Jett 50 in a Matney Models Zoomer went in at about 160mph from about 500 ft. from total control loss. Dug out my old (4th year) Jett 35, cranked her up and won all three heats, lapping most. Darn thing just keeps getting better each year of love and care. Same for the 50 and especially true of the 90. They are all getting better with age, love each and every one of the things. A OS run the same way and hours will be lucky to make it through the first year, period!!!!!!!!!!!!!!!!!!!!!!!!! Just my opinion.
