This is a high quality feathering shaft wrench for use with RC helicopters. It features one way bearings in 4mm, 6mm, 8mm and 10mm which will hold your feathering shaft in place so you can unscrew the bolt from the end of the shaft.

This is a very useful tool to keep in your heli flight box as we all know how difficult it can be to get that last bolt out of the feathering shaft. With this tool there is no need to use pliers which will damage the surface of your feathering shaft. Simply slide the shaft into the appropriately sized one way bearing to lock the shaft in place for bolt removal.

*Note: Fits feathering shaft sizes 4mm, 6mm, 8mm and 10mm.
