RE: O.K guys, lets talk about engines...
Jim,
I didn't necessarily mean that comment as a jab at the YS engines, but the YS fuel system does require a higher level of attention to detail with respect to fuel cleanliness and fuel line connection security and tank integrity than non-pressurized systems.
The YS system should solve the problems associated with the high tank placement of the P7 arf, and that's a good thing......
