I just recently lost spark for my DLE30cc engine, found to be a bad Ignition sensor, I will say that the part solved my problem, and the engine seems to run fine now, but for the amount of flights I have had on this engine,(maybe 25 or so) I am not impressed with the overall quality of DLE engines so far. I have been through 3 carburetors on this engine, and finally purchased an American made carburetor that solved my fuel issues. spent a lot of money doing this! I own a Desert Aircraft engine that I have flown relentlessly for the last 3 years and have had not one problem, in the future I will be purchasing only Desert Aircraft engines made in America, due to the quality and customer service, I tried to get warranty help with the DLE engine, and only got excuses and apologies, but no help. so I am sorry to say I will not be purchasing any more DLE engines. when this DLE30cc is worn out I will be replacing it with a DA35.
