Today i installed a brand new Saito 72 that has been sitting in its box for more than ten years and today was the first time it has seen daylight since then. The stock aluminium engine mount was too small for the big Saito but as luck would have it i had an old Hangar 9 universal aluminium mount that came out of an Alpha 40 and this bolted straight onto the firewall without any modifications required. I also used a Dubro fourstroke throttle linkage that i have on all my fourstroke planes to connect up to the throttle lever on the engine. This works great everytime without any problems.
