RE: NEW DLE 20cc Gasser! (Data & Links 1st Post)
I think the QA is inconsistent. I had 52 flights on the DLE-20 on the Ultra Stick until I sold it. Now I have that at least on the Velox and I have had no issues with Stihl HP Ultra and I fly the Velox very hard. I am running no alcohol gas if that makes a difference.
