  I would suggest to adjust the handicap of FES propellers equipped gliders down by one point.
For example: Discus 2c 18m FES from 106.0 to 105.0, HPH 304 eS (Shark 18 m FES) from 110.0 to 109.0 etc.
This reduction of handicap by one would only be applicable if the FES propellers are installed.

Hi,

It is a fact that the propellers of the FES don't help the performance of a glider.
Some other handicap lists already have made adjustments to handicap of FES equipped gliders vs their pure glider/Jet version.
I would like to request to adjust the BGA handicap/ Glider Speed Indices of the gliders that have the FES propellers installed?
