easy break in, just get the motor to at least 180 deg before starting. I made sure motor was getting over 200 for first few tanks (use foil around cooling head), Holds a tune, not real finicky on needle settings, if your off 1 hr on HSN its not going to flame out. Will buy another as soon as there back in stock. THX Dialed RC Hobbies, great motor and not spending over $300

Great engine ! Break in is very easy and tuning also is .Plenty of power also. id recommend 25% fuel at break in and than go to 30% after it makes it a monster on the track
