Great wrench. Its very nice to have 4 sizes in one unit. It fits all my helies except for the smallest 3mm feathering shaft on the older trex 450 flybarred units. The one way bearings work great with no slipping. Now we just need one that does 5 sizes.Should have bought two. My friends have borrowed it and used it more that I have. Love it and for the money, it can't be beat.I have 7 heli... So u can catchNice hand tool, works well! Quality is medium but ok!Sehr nuetzlich, um gut gesicherte Schrauben aus einer noch intakten Blattlagerwelle zu drehen. So ein kleines Werkzeug habe ich gesucht und jetzt gefunden. Danke Hobbyking!I dropped it a few points because it doesn't work for my feathering shaft despite appearing to be suitable for 450 Helicopters.
Maybe (TBF) I should have realised that my particular feathering shaft is smaller in diameter than 4mm (TREX SE style helicopters use a 3.5mm shaft.
I'm hoping I can find a material to make a sleeve now that will make my 3.5mm shaft fit one of the one way bearings.
If this stops someone making the same mistake that I did, then it was worth the writing.
Looks like this unit is made by Tarot. It's great quality, arrived a bit greasy and dirty but that's fine. I'm not sure what type of feathering shafts it's meant for by my Trex500 shaft fits in the second smallest bearing, the rest are huge! I can't see a main shaft ever needing to be clamped down, but it does fit larger main shafts as well. Unfortunately, does not fit 250/450 feathering shafts. They are too small. Would be nice if there were smaller sized bearings.Fantastic tool! No more scratches on brand new feathering shafts! Also very good to remove feathering shafts for maintenance or after a crash. I recommend this product!alles bestens wie gewohntuselo para revisar las balineras del main rotor de su helicoptero
