I think this is called Karma, DLE basically stole the design of its engines from DA and sold them to the us market. Only marginal at first they finally got a decent product (not to say that I would own one). Now years later after they have become a real name in the RC community somone has theatend their business by copying their copy, imagine their suprise. Who would do such a thing? Well I say good for them, I hope they have a wonderful time dealing with the outcome. Desert Aircraft may have came out with their own engines after dealing for 3W for a long time, but it was not a copy, it was a brand new design all its own. I understand that DLE isnt the first company to do such a thing but they have been the most successful which puts them in the crosshairs of the consumer and the competion. As a business owner myself I have a real problem with theft of ideas, patents, product design, you name it just torques my Jaw.
