RE: RCD 26 CC Gas Engine from Hobby King
Also keep in mind that Nitro Planes have poor manuals and many of their planes need to be fixed during assembly. Also their support is suspect as well.
To answer your second question about battery's. Yes you should use two. One for the receiver and one for the engine.
Also Jody is no longer with VVRC but they still service the DLE and are very good
