It didn't come with the gear? Hmmm, sounds like they may have shorted you on your kit since they are clearly shown in the marketing photos. Does it appear that there is a model number of any kind next to the gear as depicted on the plan? I have two MK kits in my closet right now. Though both are intended for use with retracts, they both came with nice tail wheels. I would have thought a fixed gear model would come with the main gear.

You might want to check with the store you bought your kit from. If they don't have it, Hobby Net Japan has the MK Mighty Gear M Type (48-63) listed for $23.00. I think I would try to find out if the M Type is what's right for your kit before placing the order though. An email to Hobby Net Japan should get you an answer pretty quickly.
