cheers guys, I've beein looking round ebay seen some good prices for the 8 port on there and also other motors like the Rossi Mamber.
I have heard those mamba's are a pain to break in. The OS are easy to break in and hold a tune well. Even an axial .28 spec 1s will run great and they dont suck down fuel either. And they are great engines. For how cheap they are. They are a great mill. But axial does make the mills for HPI.
