Then what Hans says is correct, the Viper should be officially measured by a Texel official or an official accepted by Texel committee (ISAF measurers I guess) to get an official handicap awarded. Currently it has none.
So, if the Viper was designed to the F16 rule, and meets all the requirements then it should race on:
F16 1-up Texel = 101
F16 2-up Texel = 102
We don't have any scales at our club so weight cannot be verified (but it does "feel" a lot heavier), and there aren't any measurers locally. Giving itself a rating of 104 isn't really justified until it has an official measurement cert to qualify that number.
