There is a Dynamite engine on ebay with a red head and says dynamite in red letters down the side of it from top to bottom and nothing on the other side. The person selling it says its a .15 engine, but by the looks of it, it is not a mach or an spd, or s. It definately looks older than that. I was thinking about buying it, but parts are already becoming scarce for my Mach15 I have already. Anyoneknow what this thing is? youcan go on ebay right now and see it, it has multiple pics.</p>
