    Rear Rotor Blade of SR Keeps Breaking



    I've run into an issue with my Blade SR where the rear rotor blade keeps breaking. Iknow it has to do with the amount of torque but Icannot seem to find the correct amount of torque for the "capping" hex screw. Please note IamNOT talking about the twohex set screws. I either put it intotoo much torque and the blade breaks off (without even hitting anything including the ground)OR it is too little torque and the blade slips on the axle and fails at rudder control. Anyone out there have the correct (perhaps secret or mystical)way to torque the hex screw that caps off the actual plastic rotor blade so it won't break when the rotor blade begins to spin?

    BTWIalways place the white rear rotor blade ontothe axle hub so the leading edge of the blade is leading to the counter-clockwise movement of the tail rotor blade spin. So Idon't think it is a blade direction mounting problem. Any help anyone can provide for me with this Iwould greatly appreciate it as Ihave gone through at least a dozen tail rotor blades as a result of this problem. 4 of those occurred in one 10 minute period of time!!

    Thanks!

    RE: Rear Rotor Blade of SR Keeps Breaking

    I thought I had tail rotor blade slippage one time, and tried tightening on a CP Pro 2. I didn't break the blades, but it took me some time to realise that it was the motor itself that was causing the problem. What appeared as blade slippage, was in fact a motor that couldn't keep up.
