If you are planning on getting a DL 50cc engine then plan on buying a new muffler within a few weeks... I have 2 of these and the exhaust rips off on the top of the stack right at the canister due to poor welds (that Leak) and too thin of material. There is no support for these engines either as i can write this and no one will respond... But i though i would let everyone know they are good running engines but the exhaust is terrible garbage and i received no help... I bought mine from a claimed U.S dealer on ebay which probably sums it up there.

Any way here is what it looks like after a few weeks of flying...
