Lutz, being a novice in all of this I am a bit bewildered. I have done my homework and understand the importance of noseweight and thought that a gauge made for the job ought to be accurate. Are you saying that they are not made to an acceptable tolerance? If this is true then surely, if something happened due to incorrect noseweight setting, the manufacturer could be held responsible? Are these things not checked for accuracy before leaving the factory? Im sorry for seemingly putting you on the spot, its just that I have noticed youy do tend to give factual and precise information. Cheers, Derek.
