No matter what I do or how I tune my DLE 30 (V1), it runs poorly and invariably dies, either taxiing or in flight (3D flight especially). The engine has a mortal design flaw and I basically got fed up with it. I believe this line of engines was brought to market too soon and lots of unsuspecting customers are paying the price with crashed airplanes. DLE acted irresponsibly and needless to say, that was the last time I bought from them.
