Well I finally got to run my clockwork B5 yesterday for the first time and it ran great. I really lile this engine. I was getting right around 10-11 minutes a tank with the temps in the low 200's, 205,206,212. I thought that was pretty good for the temps being that low. The straight stretch wasn't very long so I didn't get to wind it out very much. I had 1 flame out all day and it just happen to be the 2nd lap of the main. My pit man got it fired back up and it ran flawless the rest of the race. I had a few people come up to me and say damn that thing is a beast. Thanks Neil for such a great engine. It made my day so much better not having to worry about tunning. I tunner on it when I first got there and it was good all day long.
