Tag, thanks for that motor. The first time I I spun it up was with no load and it sounded weak compared to the Novak 17.5 I have. Then I took the new 12r5 with the Duo I got from you for some practice and tuning, and was I surprise. It was playing possum with me till it got on the track. That motor felt and look ballistic going down the straightaway. So thanks to you I now have some good HP to play with.
