Hi! I have bought DL 50 at
www.peakmodel.com for my Spirit of Pitts , pictures here

The engine has worked 2 hours on the ground and never flied with airplane. Work of the engine was astable and suddenly it has stopped. The compression has been lost. I dismantled the cylinder and have found the damaged piston, the cylinder and a ring. The engine does not work. I have E-mailed to 3 addresses at peakmodel.com ,but did not recieve any answer.
Where can I buy parts for this engine?I have information, that there are some manufacters of DL 50 ,and parts are incompatible.
