bikinidan That is a problem with the V761 planes fitted with the bigger 10mm motors - when the prop stops suddenly (or gears jam with grit) the extra power spins the motor pinion loose and off the shaft. No brass replacements yet but you can use the 11 teeth pinions for the Hubsan H502 quads (and some others.) However you will have to ream or drill them out from 1mm to 1.2mm to fit. Then glue them on with loctite bearing retainer or super glue. There is no motor fail-safe with the V761 planes either. If you lose signal they will fly away. EDIT!....Hooray! The latest versions of the V761 planes now have motor failsafe - finally fixed after all these years. Check that yours does have it before flying though as there will be old stock out there!
