Yes, it's a great engine. I had a few that ran great on 15% Cool Power. As mentioned, use an OS "F" Plug.

As Flying Freak noted, the pushrods in the rear get good protection in case of a crash. But the bad news is, this slants the glow plug forward and very near the prop.

Be VERY careful when removing the glow igniter! In fact, you might really want to consider a DuBro Remote Glow Igniter pictured here:
