Seeing as the the seller on ebay can't be bothered to even reply to my two mails,
i will have to take him off of my shopping list, anyway i worked out 30% being 8cm,
and PERFECT, as i flew it today, a bit faster than i remembered, than when it was
fitted with the Rossi and it alsohas a bit more response with the OS 60 i also took
out 50 gms of leadfrom the nose.
