What is best glue to fix a broken R/C Remote Control Flying Saucer propeller?

Yesterday my daughter bought my grandson a radio controlled R/C Flying Saucer. It is dome-shaped with a plastic propeller underneath and inset within the inner body. Operating the remote control when the saucer is on the ground causes it to rise and fly. However my grandson allowed it to descend onto an object on the floor whilst the propeller was still revolving causing it to snap in two. We've tried Loctite Super Glue to no effect. Has anyone any further ideas we could try to fix the propeller, perhaps a different and more effective glue. Thank you.What is best glue to fix a broken R/C Remote Control Flying Saucer propeller?
