Chris -I have been thinking on this 5300 rpm Static and your claimed 5300 rpm on
Climb out. 
With a fixed pitch propeller and constant throttle: 
If the engine is properly tuned (carburettor balance) and everything is as 
expected
and you have correctly performed your Static run up engine rpm check - you
must get an rpm rise, as the aircraft gathers speed, on ground role and Climb
out.
The only exception to this would be an abnormally high Climb out angle (above 
best
climb angle), which may have the effect of limiting rpm (you should still
have some rpm increase in ground role.)
Is your tacho working correctly?
If you are not getting an rpm rise, something serious may be wrong  get your 
local
Europa or LSA aircraft guru to help diagnose the problem.
