Hey Jim.Īre you talking about a true ultralight or lightsport? If you meant ultralight, Challenger's are far too fast and heavy. Unless they offer some kind of unlimited warranty for that time, it's just a number. Jim, if you go in with the expectation that the Hirth engine will last h, you sure to be disappointed. So far the F33 would be my 1st choice in a 2 stroke, should i go that way 2 strokejust would like any and all information on these engines, the good and bad of them. My question, does anyone have first hand experience with a F33? I read that TBO is around a hours, compared to on a Rotaxplus i've read that all 2 strokes are prone to stop running, especially during idle. A Challenger is another choice, however there we go with the 2 stroke. Second is the Belite, however if you choose the 4 stroke, it jumps the price up to around 32k, up from around 17 with a 2 stroke. It has the 4 stroke which i would really prefer.
