Hey guys, I am nearing completion of my CMP BF-109 that will be powered by an NGH-GF-38 engine. I previously had an NGH 15 CC engine with very good results. There was a lot of negative info posted about the 15 CC engine as well but my experience was quite good. Maybe I was just lucky but I am not going to worry about the 38 until I try it myself. I will post pictures and info about my experience with this plane and engine combination in the near future.
Best wishes and good safe flying.
