I Called Barry this morning and he told me he would not program the ECU to reach 145K because of safety issues. Barry also told me K 80's are 80N class turbines which equates to only 17.89lb of thrust which is just shy of 18lbs.
The specifications clearly state
Thrust: 8618 g @ 21.1° C. (19 lb. @ 70° F. )
Is King Tech representing K80 series engines as 19 lb thrust engines, when they are really 17 lb thrust engines? If this is the case we have a serious problem with them not being truly honest or sincere by providing consumers with false information. It clearly states in the owners manual and the King Tech website the K 80 is a 19 lb thrust engine.
Is there anyone else having this issue?
Hibbler,
I have an older K80 that is putting out over 20lbs of thrust. I have read in other threads that the manufacturer test runs the engines and tunes them to the thrust they should be putting out and the advertised max thrust is just a that, whether its 139,000 or 145,000. The manual just shows the max RPM the engine is not to go over, not the RPM it is to be set at. I know all my Kingtech's put out more than the advertised thrust and the RPM's vary from what the manual says. I also know that other manufacturers use some kind of formula to calculate thrust base on 15*C temp, sea level, barometric pressure and such, but all my Kingtech's put out the power they say it should. Have you put your engine on a bench and tested the output? Do you know you are not getting the proper thrust at 141,000rpm? Let us know what your real output data is before you cast stones!!
