![]() ![]() The prop choice is also dependant on the type of model and style of flying, so choose accordingly. The OS ad YS will spin the larger props with ease, wont dead stick (when set up correctly) and last longer. I currently have a SC 120 and a 180 ,both came second hand so I knew they had decent comp but they are still down on the OS or YS Engines power. Get your money back and buy a proper engine OS or YS. My colleague has a Tiger Moth with a ASP 120 FS for pulling power, unfortunately I don’t know what the prop size is, maybe 16 by 8, the performance I would describe as adequate plus, and it’s done a lot of flying, usually up to 20 minutes per flight, and 2 - 3, sometimes even more flights a session, and that includes something of everything. Dont be put off by the old "it needs more running in " or "they develop the compression when they fire" fob off. If your engine has low comp when warm return it while in warranty. Occasionally you will find one with good compession and therefore a good power output but most have at best a soft/poor compression and struggle with a 15 x 8. A Club mate bought Three FS SC's, 2x 70's and a 90 from a well known supplier in a sale and only one had good compression and run properly with a reliable tick over/idle. Your right about the ASP/SC's FS 120's being down on power. ![]() This is a bit off topic but it is relevant. ![]()
