Hi Mike.. as much as the wood bearers/engine plate might seem out of date or otherwise.. it really is a nice way to mount the engine.. and.. those bearers play an integral part of the forward structure, and cheeks of the plane.. they add alot of rigidity. They really are nice to use if a little time is taken in building them. I've found just liberal coats of dope is all that's needed to keep them solid for years... and nice thing is its all there in the kit. If my memory serves me.. all I remember having to do is dremel out a bit of clearance for the engine mount screws(engine to plate)... as the plate just seats in and secures with 4 screws... you really can't beat that mount.. even with a plastic/resin mount.. The stock mount will definately give you a stronger front end.. it only stands to reason.
Just a thought here.
