Has anyone tried dieselizing a Norvel .049?

Thanks Ian,

I have been watching the NV site for a while to hopefully purchase a .061 and .074 diesel head. I will keep trying. I have had good luck with the RJL head on Cox engines. MECOA says that they will work on the .049 and .061 Norvels. If I am able to get some time tomorrow I will try one on a Norvel .061. If I am able to try it out I will post the results.

Well, I tried the RJL head on a Norvel. I grabbed a well used Big Mig .061 Revlite R/C and clamped on the RJL head along with a MAS 7x3 prop. It was beautiful! Within a few minutes the engine was purring along at 13,400 RPM. A little backing off the compression and it was rock steady at 13,000RPM with a good idle and good transition. Also, the head temp was much lower, like on a purpose built diesel. I think it is because of the head size in the revlite engines. WOW, this was beyond my expectations. I also tried a MAS 7x6. That yielded 9,600 RPM but the idle and transition weren't as good. Maybe I will try a 8x4 next time. But, I am so happy with the 7x4 that I might just stick with that. I am thinking that this might be the ticket for an Ace Alpha. This made my day.
