Raptor G4 - Servo Support Failure

[Jamin_00]

Very nice!!

How much they charge you for the unit replacement Stu?? Only ask as mines apparently dead to although it came off flying heli, go figure!

[jwatts007]

If I was too go electric that is I would do, did you buy a nitro kit or is it a E model with a yellow canopy....

[Stuart]

Under warranty Ben its only a two weeks old....

[Stuart]

Its a Nitro kit converted to E

[jwatts007]

The only other thing that is different on mine too all the others I have seen is I am using normal servo horns the balls are a little further out than the TT ones that come with the kit...I wonder if this could be adding more leverage too the mount enough too snap them...the reason I have these horns is when I built the model the JR fitting were not available.....

[Stuart]

A possibility anything away from a std stock setup would be outside the manufactures parameters - I would be surprised if this was it but again the extra loading may be just enough. At the end of the day you can only remove each element until its spot. Mine is completely stock on the servo mounting I have done a minor mod on the washout arms to reduce some movement using a smaller inner bearing and some washers from synergy and my tail servo on the nitro is rear boom mounted. But other than that I've never suffered touches wood any snapping of the elevator mounting.

We will find out JR fittings on there way and a new servo mount...even managed to get another servo case.....

[jwatts007]

It has happened again too my G4...this time both mounts broke in flight...amazingly the heli is undamaged...I just cannot fathom out why it keeps happening...could I have the numbers others are using in there V bars cyclic ring...but I just cannot see how the servo would do this each time...they are JRs and the spec says 17kg of torque...i am not a 3D pilot the hardest I push the ele servo is doing a hard stop.from FFF and flip it inverted...anyone got any ideas this is the 4th time now....JWG4eleservomount_zps77acad36.jpg

And I got it on vid. According to JW the drop just before was not commanded.

[jwatts007]

here is the Vid the blade fart must be when the mounts let go....

[Jamin_00]

That was the blades??? I thought it was you

Sorry to see this John , hope the damage wasn't much :-(
what mixing have you got on your v bar , 120 , 135 or 140 degrees ccpm ?
I can only think this is binding ?!

Hope you figure it out , mechanical failure is so annoying

[rachel]

In the swash tab, select the doctors hat to create your own swash.


For the Angle you want to type these numbers in:


CH1 = 270
CH2 = 135
CH3 = 45
CH4 = 0


And for the Distance:


CH1 = 70
CH2 = 99
CH3 = 99
CH4 = 0


Hope this helps

Sorry to see the video, but glad you landed without damage. Mine is just on the standard HR-3 Swash in Vbar (not sure if this is correct but it's what I run lol)

Servo parameters:
ch1 270/100
ch2 150/100
ch3 30/100
ch4 0

Geometry correction ON
Digital servos
85 cyclic ring
20 pitch pump

96 on pitch
98 on cyclic
690mm blades

cyclic:
style 74
agility 104
108 gain


May you please post your vbar file here or your settings?

Cheers

Swash angle 270-135-45-0
Distance.....70-99-99-0
Cyclic ring...80
pitch pump..30

thanks for your help...
