RE: LRP 28 Spec 2 Trash???
It shouldn't be an issue realistically, just give them a bell. If you where in the UK the distributor wouldn't be suprised at all, for some reason I have seen SO many blown LRP/SH engines with destroyed conrods. They should sort you out though.
Oh and the STS 28 is a completely different engine, its not as rev'y as the LRP but its got awesome power, its as reliable and easy to tune and cheaper still, overall its a cracking motor for the money.
