Has anyone actually done a static thrust measurement for the 26, 35, 45 and 58 cc gassers?? what were the props used and what was the thrust obtained?? Amparticularly interested in the 26 and the 45 cc as i own those, but would also like to know the others

Thanks

Own measurements, not factory data. All done after the engine was well warmed up and rpm are stable. The cold engines provided up to 10% more thrust.
26cc:
16 lbs on tuned pipe and Menz-S 18x8 @ 7600 rpm
35cc:
20 lbs on tuned pipe and Menz-S 18x10 @ 7600 rpm
18.5 lbs on muffler 3271 and Mejzlik 18x10 @ 7600 rpm
21 lbs on tuned pipe and Mejzlik 18x10 @ 8100 rpm
58cc:
40 lbs on KS tuned pipe, Menz-S 24x12 @ 6100 rpm
37 lbs on KS tuned pipe, Menz-S 22x10 @ 7300 rpm

edit: My scales are accurate within 1 oz at 55 lbs

You are welcome to add your own data on the engines you have. Please state muffler, prop size/brand, and rpm along with the thrust measured
