That one has the long threaded crank. If you want that one, you'll either need to cut the crankshaft or buy: http://www2.towerhobbies.com/cgi-bin...?&I=LXWY00&P=Z

Here is the same engine, but has a rotary carb: http://www2.towerhobbies.com/cgi-bin...?&I=LXXA43&P=0
and if you go with this engine and you want a slide carb: http://www2.towerhobbies.com/cgi-bin...?&I=LXARU1&P=7

by price it's better to buy the one you listed and either buy another crank, or cut the one you get with it (just don't cut it too short)
