The other day while flying my Trojan T28D, I was coming into my landing flare, when all of the sudden the motor locked up. Luckily i was close enough to the ground that there was no damage to the plane, but the motor started smoking briefly, and now will not turn for more than about 2 sec. before locking up and whining. Im not to expierienced with electrics so thought someone may be able to answer what is going on. I wasnt sure if it was a bad motor or esc. I havent ever had any nose over landings or anything, its only been flown about 3 or 4 times, here's the link to the videow if you're interested, it happens at the very end as im coming in to land. Thanks.
