Hi
Interesting when i looked up the numbers last night I thought the YS came out 3.5mm shorter than the OS from the centre of the mounting lug to the prop driver. My reason for asking is too have a back up plan for my Synergy. So far it has run okay with the Minto but in case it proves a problem I am looking for a back up plan. Pricipal problem is the header keeps coming adrift but i beleive there is a fix for that. ( ps One of my pet hates is manufacturers using modellers to do there development).
