just finished R&R of my main motor tonight. i was flying with my original motor today (10mph wind, 100F) and noticed slightly lower headspeed from liftoff but continued the flight anyways. i landed to relax my thumbs and cool the motors after 6min of flight. when i spun up and lifted off again, i noticed a very sharp drop in headspeed so i headed down again nearly tipping it before executing a half*****ed auto-type landing thingy. upon inspection, i noticed the jps connector on the motor was melted. when i removed the motor it clicked like a tin can when i spun the spur.

i was lucky that my main went out only 3' high. i plan to start a detailed flight log and implement routine motor replacements. my first lasted about 5hrs of flight.

i'd appreciate any advice as to how many hours of flight i should go between both main and tail motor replacements. i'm using the gws dd motor btw.
