I have had an A.E. .15 engine for quite a while now, and most of the time it is an amazing engine, really Fast! But for the second time in 3 months I have blown the connecting rod and the engine has seized both times ruining the piston and sleeve. It has a lifetime warranty so getting it fixed is not that big of a deal. I was just wondering if anyone else has had this problem with this or another engine. A.E. engines are made by Thunder Tigre, usually a great brand, but I was wondering if I should consider switching to O.S. if this is a common problem with A.E.
