RE: EME new engines, 35,60 & 120 twin
maybe 100+ rpm's,i still think it will improve a little when the ring fully seats.i ran the 60 from day one on redline @ 32-1, now with four gals. of fuel the ring still shows dark spots, meaning that it is still not broke in.despite what EME and Frank Bowman says to break in on dino oil.the last time i flew it it was on pennzoil @ 32-1 and i will stay there till it fully breaks in.one thing i did notice is that i lost 75 rpm's when switching to dino oil.
a friend has just bought a DA60 with a Falcon 24-9 prop,now i can compare the two with the same prop,if i can talk him into trying out the prop.
i will let you know what happens with the 24-9 prop.
one more thing the engine is smoothing out nice at idle,but it never shook to begin with.now it is just starting to rip the the Xoar 23-8 and i will stay with this prop,i like the speed and the FAST vertical climbs,unless the Falcon 24-9 can beat the Xoar.
