Rick,



My point is that there is no handicap penalty for "being a motor glider". The only factor that is measured in the handicap calculation is the additional weight of the motor equipment. The FES is a new situation in which it has both additional weight AND IMPORTANTLY it also has a significant, measured aerodynamic disadvantage which needs to be taken into consideration objectively when considering its handicap.



In this case, if you run the numbers, the FES handicap for the Lak17bFES is only considering the additional weight (75lbs not 135 I think boys). Regardless, no consideration or calculation has been factored in (current US handicap) to compensate for the aerodynamic drag penalty of the system (propellers, etc). These propellers effect the Lak17bFES performance each and every second it flies in contest flight. It should also be considered in the handicap ALONG WITH the extra weight.



I think the current handicap is incomplete and unfair to owners of the Lak17bFES and highly discouraging to potential new owners or those considering a modification to a current pure glider.



Sincerely,

Sean

Duly noted, Sean. Way too much noise on a 2% handicap change that nobody besides yourself gives a flip about. A couple of years ago the handicap on my LS8 was changed from .925 to .915, no idea why. Rather than screaming like a little girl about it I just concluded that - just like a fine wine - my glider is getting better with age. No conspiracy here, Sean, move along..

Herb,
Thanks for your opinion. Brilliant as usual.
