ORIGINAL: proptop Guys...I just got an X45 and X60 off *bay. I had never seen the X45 before...and the guy I got them from said it's like a longer stroke X40, only w/ a front intake. Looks like I will have to do some comparison flying this spring with my K&B 6.5's Question: The X 60 came in a side exhaust and a rear exhaust version. Is there any noticable performance difference between the two? The pic in the auction was for a FIRE X60 but he sent me a side exh version by mistake. Thing is though, the side exh. version is in great shape...virtually brand new w/ only a little test stand time on it. If there's no or not much difference between the rear vs side exh. versions, I might be happy to keep the side exh. version, but if the rear exh. is better, then I'd rather have the FIRE... -------------- I may be wrong, proptop, but I think that the side exhaust X60 is a bit of a rare bird here in the USA. All I ever remember being sold at Tower in those days were rear exhaust versions of the X-60. It is easy to have a header made up to divert the exhaust gasses around the cylinder and up the center of the model, if that is your think. On the other hand, using a rear exhaust engine in anything but a pylon or pattern model is a bit of a PITA. With all things being equal, timing/porting/etc., I see no reason why the rear exhaust will have a power advantage over the side exhaust. Ed Cregger
