Hey guys its my first post in the 1st gen section, I am going to go look a SA later today if it all works out right and was going to do a compression test before I buy I know my FC is aroung 130psi max on each rotor but is a 12a the same? What compression numbers should I get out of a good 12a? I know how to do a compression test on my 13b, just wondering about the numbers on this one. Thanks

 

Between 100-120 is good. 80 Works even but expect a rebuild in the near future.
