I just canceled my Tower Hobby back-order based on what I have read here. Thanks for all the effort guys. The last thing I want is stalling problems. While it looks like the problem MAY be limited, and the factory MAY make design improvements, I don't want to be the guinea pig, plus I need to fly in cold weather. At least a few people here were having problems with the DLE30 stalling. I used to work at GM Rochester Products and I have a huge respect for fuel pooling, carburetor & manifold parts design and quality. Tremendous effort was always required to make carbs and manifolds that worked, it was an art. You have not even touched on the 10% alcohol, and range or Reed Vapor pressure fuels that the carbs have to contend with. In other words, it is no surprise if it takes $500 to build a small gas engine that meets all our requirements.

I have four planes I would like to use a DL30 on because they are very expensive to run, good 4S fuel is over $30 here. They are currently running ASP 180 [CMP Katana 72"] and ST-2300 with Perry carb [SIG Rascal 110] . I concluded that I want to get into gas with a 50cc. For 30cc, OK let's say cost is no object but I need 18# thrust and weight [eng, muffler, ignition] under 3# . What should I buy ? For example, EVO 26 [$450].
