I've had RS 333 RB retracts for a few years in my H9 Hellcat and they have been used very little (maybe a dozen flights). Today, I cycled the retracts and one of them just keeps running (motor is spinning, nothing else happens) in the down position. Has anyone else had this issue and did you resolve it yourself or send back to Lado? Since Magnum RC no longer carries them, I'm assuming I'm on my own to repair. Ideally, it would be something which could be done on the workbench. Thanks for any insight! I'll continue searching on this site for related issues and remedies as well.
