Anyone have the specs on this motor ? Could this motor hold its own compared to today's motors ?

RB C5

Thank you Pedro, but do you know if its a 7 port ? or any info on the power/RPM's ?

There is a CS and there is a C5.

The C5 is a 7 port with M.E.S. (3 exhaust ports) and will not do much under today's high end mils.

The CS was a limited edition motor with the same specs as a C5

Not as long as I entered the modeling world in 2006.
I did not find anything about the RB engines in terms of Practical Regimes and horse power.
I think RB has never released this HP information and Pratical Regimes.

Thanks Roelof for the info again you are the man!
