I Just Bought a E Flight Carbon Z Cub and it seems to be a pretty nice plane except for one small problem I have noticed . Every ball link on the plane is missing the little half moon shaped piece that should be between the ball and the control surface . When you put the bolt through the ball link there is a little half moon shaped piece that goes on next and that allows the ball link to swivel properly . On my plane every ball link was missing the little half moon shaped piece . On my maiden flight the elevator link fell apart because I did not have it properly locktighted. Luckily I was not airborne yet and I was able to stop with no damage . I then replaced all six ball links with new Du-Bro Ball links . . Other than that this seems to be a fantastic plane. I am wondering if anyone else has noticed this or am I the only one.Are they okay with out this little half moon piece? as long as they are lock tighted ? Maybe with lock nuts ? It just seems so much better with the proper ball links in place .

FOR THOSE OF YOU WHO HAVE HAD MOTOR / ESC ISSUES:


There have been a few YouTube and vids posted showing people who have crashed their CZC for no apparent reason. Their piloting skills seem adequate. After watching those videos I was curious about why? I have a hypothesis that it is due to the stock settings on the ESC!


If you read the manual that comes with the ESC on the CZC it says that the Voltage cutoff is set to 74% of startup voltage. START-UP voltage not battery pack rated voltage. So if you put a 6s battery in the plane that is not 100% charged (let say 4.01 per cell) then that is what the ESC is going to read as start-up voltage and calculate cut off voltage to be 2.9674 per cell. That's way below what the lipo should be discharged to.


I feel this may be the reason for the faulty claims on the ESC or RX operations. READ THE MANUAL FOR THE ESC!!!!

I have one and have other gas and glow models with ball-joint control connectors and I'm not sure that the "little half moon" pieces you are speaking of are necessary. The control horns of the CZC have flanges molded in that are a little higher than the surrounding surface to lift the ball for clearance if you installed them as shown in the drawings in the manual.

Just because DuBro solves a problem one way doesn't make it the standard for all.

CZC is a great model. We have five locally and no one has reported bromlems beyond the "hanger rash" the foam picks up. Super float plane.
