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.
Pliars do not "work fine", they scar up the feathering shaft. This costs less half the price of other tools of this type and supports all the commonly used feathering shaft sizes in one tool. Buying these sizes in the Align wrenches will run you over $30, this thing costs $8.
Sorry to say but no.The smallest size on this wrench is 4mm which is for use on the 450 class helicopters.A 250 class feathering shaft would be 2.5mm.Too bad they couldn't have added one more sizing of "one way bearing" on the wrench.
Exactly, this tool is very useful, it's common to have one bolt slightly tighter than the other so only the less stuck one comes off with that technique, then you have to hold the bare shaft to get the other one.
Most the time you are changing the shaft because you bent it and pillars will work but if not, then you will score the shaft and have to chnage it anyway.
Or just press a bit harder on that hardened steel feathering shaft :D
Over 1000 helicopters built and never needed one of these before lol.
Nice tool , but like those multi screwdriver bits theres always something that you never really need :D
Works great. Slight imperfections in the plastic handle. I look the handle off the wrench itself anyways, as I will only be using it on a 450 and do not require that much leverage. This way I same some space in my toolbox. hehe. PS, it came in a TAROT packet, so I suppose its a TAROT product with the Turnigy label engraved. Sweet.

Tested it yesterday. Tool works great, firmly holding the shaft without scratching it. Must have tool if you need to disassemble the shaft without thowing it away.
