I agree with squirrel about those JR 285M's, they really aren't meant for 450 Helis, maybe 250's. No good for 450 3D flying. They just don't have any real world torque or speed, even if you over juice them to 6.5 volts. The larger JR servos for the bigger birds are great though.

Yeah they supposed to be, but the main gear is designed to break off " they are designed to sheer away," that is what I researched.

Rather to leave sources nameless. It is better that way.

It looks like a cool design with good intentions. However if they are breaking like that chances are its due to Hydrogen embrittlement. Ti is a very hydroscopic material and if the sintering process is sloppy you will have alot of extra Hydrogen that comes from just plain old water moisture. Those gears should not be breaking IF they are processed correctly, the cost of the equipment is close to $80k USD to burn the specimen and measure the H content, for a $100 servo I highly doubt they will ever get that capability. I will almost be safe to say if you sent the broken gears to a lab you will find the H content does not meet ASTM specifications.

Yes, I too would be very curious of where you found the information, would you mind sharing.

thanks ... Khan
