Whats wrong with the engine you already have in your old trainer?I would wait myself.
The economy thing? Can't help you there. It is effecting alot of us. I have been laid off since the beginning of December so I can't afford to go to the field often. The only thing I can really do is plan on spending the day at the field when I do go.
Well it is an O.S. .40 LA and it doesn’t have the power I need. The metal thing that holds the glow plug and attaches to the crankcase (have no idea what it is called) is leaking and the previous owner striped the screws [:@]. This has apparently lost me about %10 of my power. That is what most of my club member say so this sounds plausible.
