all the adds I read was that the engine was a .5cc engine. Now I am seeing that the one in my kit is a .8cc... The kit is done, I switched to a 5 cell pack due to the use of Spektrum, but With the spektrum receiver, I wasn't able to use the on/off switch. I am thinking of putting the receiver on the steering servo and use the on/off switch, but hadn't done it yet. Sorry, no pics yet, wifey has camera at work.
