Dave... Thank you for offering the videos. One of my issues with glow is the rpms needed to obtain good performance. I was greatly encouraged by HH reps offering that the power band was wide enough on this engine to run a prop that didn't have to scream to perform.

I thought the video of your use of a 13x6 was cool and the tach to me showed a pretty good number with the 13x6. It encouraged me that I might get away with a 14x4 funfly prop on a slow flying funfly plane and it not be a screaming meme... my nerves will greatly appreciate it.
