This was already posted in the training board but was hoping to get some more input from someone who's been in this position. One of my students owns a Cessna 185 i which he has almost 500 hours. He now wants to get his commercial i it. Do I need to have a Tailwheel endorsment to teach him power off 180's, lazy 8's, fly XC's, etc? He has a current medical and biennial and can act as PIC. I would just get the tailwheel endorsment myself but there are none in my area except for a Brand Husky for almost $200/hr.
