Default Motor shaft spinning in rotor, help!

Hello Guys!

I have two motors with almost same sympthom:

1. Suxxfly 1800kv 1:8 motor: nealy brand new, motor is working but at high speed motor shaft escapes at motor back until pinion stops it.

2. LRP Vector 8: one of the hottest-shittest and not able to "warrantiest motor I ever met
(because after 10 uses it dies in a stock LRP RTR car, moreover it discontinued and local providers selling stock ones at 50% because 90% of them are failing. If u are lucky u get another one in warranty and it will die again. Baah, sorry, iam a little bit angry.

So this LRP motor isnt totally melted yet, only the motorshaft is spinning in the rotor. Is it any chance to glue back somehow the shaft?

Thanks for your answer.

remove the rotor shaft from the rotor. Rough the shaft a little and clean both parts well. Use Permatex green retaining compound on the rotor. Reinstall rotor shaft and let dry. Should be good as new. Others have have used other types of epoxies and retaining compounds with success as well. Green retaining compound seems to be the most popular and has a proven track record.

Also if you do a search on google you will find all kinds of info.
