I don't know how the prop adapter is attached on that engine (I know it has 4 bolts holding the prop on, they should be fine turning the other way), but if it's held on by a bolt or nut of some sort, be sure to loctite it well, otherwise the only thing that needs to be changed is the timing, change it to the other side from top dead center (probably either 28 or 30 degrees), with piston ported engines the only thing keeping them running in the right direction is the timing... nitro engines have a port in the crank, so they're more picky... I'd say the hardest part would be finding a matching reverse rotation prop...
