RE: 40-50cc engine
Have been doing a little research on this matter about Zenoah, Now the parts are made in China and are assembled in Japan,
October 1999 Established Zenoah Changzhou Machine Co., Ltd. in China
All the Zenoah parts can be bought through zenoah with name on cylinder heads or can be bought in China without the name on cylinder. The cost is about $30.00 per cylinder more.
Now if someone really wanted to deceive people they could get the Zenoah cylinder from supplier in Japan and all other parts from China and no one could tell the difference.
All the parts will enterchange
Now I have found out that the engines that I posted about do not have the Zenoah name on cylinders but are of the same quality. They will come with the RC Xel ignition just like most of the engines coming out of China and carry a two year warranty. This are not engines that are being sold without testing, Thay have been flown and tested in China for a while now.
Time will tell as with all the products out of China
As for china made clones or knock offs, Have had this said about a lot of products out of China and about 90% of all RC products out of China are clone or knock offs of some product.
Look at the DL50, When first introduced to the market was called a knock off of the DA50 and was bashed hard by a lot of hobbyist and look at it now.
Just look at the most used forum post here in the gas engine section, All are about China made gas engines Why because of the low cost.
Just some of my thoughts
