Running a 12X6 wood prop it turned a little over 10K in the air and never missed a beat. I have leaned it out considerably from factory settings, using the tach in the telemetry module. I now have a very reliable idle at around 1800 which barely moves the plane. Really nice. Throttle response has been crisp and even a bit more linear than the DLEs that I am used to.
Starting is almost instantaneous and no dead sticks yet.
Are you using electric start? I find electric starting to be instantaneous as you say but hand starting is a little more difficult than most gas engines. I'm thinking perhaps the timing is a little more advanced. When hand starting it will fire many times in succession but often fail to start and I'm thinking that is indicative of greater timing advance.
Yes to your comment about the throttle being more linear than most gas engines.
