Great thread guys, thanks for the info.
I don't have experience with the OS .46LA, but I did recently finish a Deb with an OS .40LA. I don't recommend this engine at all. Besides being horribly underpowered for the Deb, it failed during flight on roughly half of the 10 flights I had on this plane. Unfortunately the last dead-stick occurred during a very low-level banked turn, causing the plane to nose-in at high speed like a lawn dart. Fuse was fractured in about 3 places (wing undamaged). Mind you, I was very careful to properly break-in this engine as well.
I have an older OS .40 with ball-bearings (can't remember model), which has been fantastic, but I will never own or use an LA again, especially after learning that others have had similar problems. [:@]
After reading this thread I've ordered a Thunder Tiger .46. Again, thanks for the info!
Smooth
