I replaced the stock eflite servos on my 300cfx with these and so far they have been excellent.

This servo is used on both the Blade 250 CFX and 360 CFX both of which I own and love flying. I've crashed the 250 badly many times but never damaged this cyclic servo. However, I have laid over the 360 twice on the ground and both times I broke one of these servos. One time, the entire metal servo arm shaft sheared and the 2nd time, I broke a gear tooth and one of the plastic housing mounts. The good news is you can separately order a new servo gear set (SPMSP1040) for $13.59 or case set (SPMSP2052) for $7.49.

There are (2) main reasons that servo damage is more likely on the 360 CFX. First, the blade grips and swash are all metal and unless you mercilessly pop a link, something is going to give and it’s probably going to be one of these cyclic servos. The other reason is the plastic 3-hole cyclic servo arms that come with the 360 CFX are longer than the single position metal servo arms that come with the 250 CFX and the 360 comes with the ball joint mounted on the 3rd hole thus providing maximum response but also maximum leverage & torque strain in a crash.

Being just a low intermediate heli pilot, I already had the rates dialed way back and expo’s on 30 until I get used to this bird. With all this servo damage, I went ahead and put the ball joints on the center hole to take the crash strain off the servo and compensate with increasing rates if needed. I haven’t had a chance to try it because I’m waiting for new servo gears and a new tail case that blew apart in my last crash!

I have had two light crashes with a 360CFX using these servos. First crash, the elevator servo gears stripped. 2nd crash, TWO of these servos stripped. Even the main blades were fine. Very weak internals. The price point for these servos is just too high for what you get. They should realistically be priced in the $14.99-18.99 range. NOT $27.00 each. These servos will strip out before linkage bends or pops off......GLASS GEARS. Be warned. KST's are 2X stronger or only $3.00 more each...

A very smooth powerful servo, but after 30 flights 2 servos lost their bearings. I may have a bad batch, but not worth loosing a heli to try again

First time out Had a rough spool up because I didnt center the blades properly before doing it, heli laid over and had a blade strike and totally stripped one of the cyclic servos but the other 2 survived, the carbon fiber blades however did not survive.... Lesson learned.
