I found this: http://www.horizonhobby.com/Products...?ProdID=SUL689

Would this fit? If it does, what else would I need?

I'd probably need this wand: http://www.horizonhobby.com/Products...?ProdID=SUL686
Will that wand fit in my rotostart?

If it does fit, does it spin it the correct way? Or do all engines turn the same way?

Thanks for the help.
