ok, cheers ballsie...
and agreed... bugger
On another point... I want to check that the spring rates on my chart are correct. Has anyone got the rates from a different source?
The reason I ask is becuase spashett was using HPI Blues yesterday, because they are apparently slightly softer than the Tamiya Yellows. However I've checked, and on my sheet, the yellow is ment to be 2 lb/in
lighter 
I've checked my calculations, as the HPI's are specified in gf/mm (1 lb/in = 17.9 gf/mm)... and it still comes up with the Tamiya springs being softer.
Thanks in advance
Ed
