Been flying glow 2 strokes for about a year. I just put an OS FS70S with a 13x5 Zinger wooden prop, using Wildcat 15%fuel on my H9 Twist. This my first 4 stroke. My question is that 1/2 throttle and full throttle feels and sounds the same is this normal? Also I seemed to have quite a bit of oil under the fuse. RPM's were about 10200, do I need to maybe lean it out a little more for better verticle and full speed throttle response?

Thanks,
Joel
