Oh I forgot to mention before: I did order the OS radial mount set for OS FS-30S (part number: 71908300). It arrived too late for the LT-25 as I had already drilled the firewall for the
Irvine mount, but I thought I would post the weight anywayas I was unable to find it anywhere online when I looked.
For comparison, the stock LT-25 two-piece nylon beams are 45 g, the
Irvine 1-piece mount was about 41g (trimmed down to 36 g), and the OS aluminium mount 71908300(with tapped holes) tips the scales at 35 g. I was amazed. If I had the patience I would have waited, as my drilling of the redIrvine mount was not my proudest moment. Also as you would expect, the OS mount provides unobstructed access to the throttle on this four-stroke engine, whichcan bea problem with the stock SIG mounts.
