RE: Are this diesel engine good ?????
FOLLOW-UP.
I contacted the Sharma factory and they are working on a muffler design.
If this is a good runner, with RC carb and muffler, it should have a place with the small field group.
I prefer a 1.5cc to an .049 because they are usually not as temperamental, you can use a larger prop to hold the noise down and they fly a model that is only slightly larger than 1/2A. Many 1/2 A models actually include the .09 or 1.5cc as an option.
