Check out the new, December model airplane news magazine. Page 145 has an ad from Kangke. The plane is $447 alone, or they are offering a combo with the Revolution 3.2 engine for $898. Normally, thats a $550 engine alone. Total savings is over $100 on that combo.
If you call Kangke directly, they will probably offer you a combo using a Brison engine at a price reduction too, since they sell Brison engines as well. I have purchased two ARF's directly from Kangke myself. Unlike alot of other ARF manufacturers, Kankge is often willing to give you a great price directly from them.
Another place to check is chiefaircraft. They have Kangke ARF's at discounted prices and they would be willing to put you together a combo with all sorts of different engines (ZDZ40, Brison 2.4, Moki 2.10, Saito 180, etc, etc.
