YS 120 SR and the Srimok 90N ECO

[Tom Kreuzberger]

Hey guys, We managed to finally get a few flight scenes of our Srimok 90N ECO with the YS 120 SR and the Hatori 120 FS-3D on it. We went through about 10 tanks so far and are pretty satisfied with the power it delivers on the stock gear ratio of 8.25. We're running a head speed of 2030rpm and 14° pitch on 690 FBL Radix. Fuel is 20% Rapicon with an Enya 4 plug. Hope you like it guys!

Very nice, would I be correct in saying, at that headspeed you would be spinning the engine at 16,750rpm a little too much for the 120...............

Jup, a little too much for the 120 but it looks to run very consistent ... anyway ... we got the 13T pinion from Kasama and try to run a 7.6 ratio lets see what this does!
