Get the new OS 75AX It weighs about the same as an OS 91 4-stroke and it is a SWEET engine!
You got that right. Mine started on one flip and idled well right out of the box. After a few flights I leaned the low end just a little but that's about it. People look at engines like this and automatically think they are over-priced. Well, you get something for that price. You get a no-fuss, strong running engine that will rarely let you down. To me that's a better value for my investment than something that may cost less but gives me trouble.
