LMAO....I think the point to be made here is not that the DA 50 is some uber GREAT engine but that pretty much any of the brand name 50's will make similar power on a given prop.

Where the DA stands head and shoulders above the rest is in the customer support provided by DA themselves. I have no personal experience with any of the other brands like BME, Brison or ZDZ but I have read of MANY satisfied customers that own them and I think that is great. Will I buy one of them myself? Probably not, because I am totally satisfied with my DA and they have my engine business for any of my future GS projects. That decision is based completely on my experience with DA's customer service thus far that has been above and beyond that of any other hobby manufacturer I have yet dealt with.
