Cabling

[Cralis]

Hiya Guys - me - again!

Trying to see the best ways to run the servo cables to the Rx. Battling. The only way I can see to get them down is getting VERY close to a servo, and the swash...









Do you think this will be OK? Do you know a better route? Rx is is at the bottom, at the back, but I can't see other ways to get the server cobale down there. That is, the 2 servos at the top.

I will of course neaten it up somehow... but that's the route it would follow...

You can't leave the cables like that, it will interfere and can result in a crash bird.
I have my RX up front and run the cables form the front 2 servos inbetween the frame forward to the RX, all the other cables form the rear servo and gyro run along the outside of the right hand frame to the RX on the top plate at the front.

I'd take off the blue stuff as it just adds weight and maked the cables bulky.

Mine is not all that easy to see from image but I ran them inside and cable tied them to the frame by the swash (there are two little holes there that look made for the job) and brought them out though the empty servo space on the right side

I was under the impression that this was a bad thing. Having the Rx in the front near the battery (mounted above) and the motor? I heard this can cause glitching...

Is it not frowned apone to have the Rx mounted there? My heli was previously configured to have the rx in front. Would this be OK?

Heres mine running through the inside of the frames with the RX to the rear & the esc up front.

I've since put spyral wrap on the servo leads where they exit the frames to prevent chafing on the sharp edge.

[Cralis]

I like that, Gazza. Seems it's the best setup. I have that funny blue stuff on my cables. Need to get that off somehow, and then - I get the feeling my servo wires have been shortened... but, I'll give it a bash.

Where's your tw3o front servos cables going? I can't seem to spot them... I seem to have prblems getting around the gears...

[gazza]

They just run from the servos down the inside of the RH frame tight enough so as not to foul the main shaft and exit at the vacant servo hole at the rear.

Alright guys. I have removed the bulky cable mesh stuff, as most people seem not to have it, and it looks like cabling will now be a bit easier.

I have tried to do the internal cabling, from the top 2 servos, down to the Rx, the way that some people say they are doing it, but I am failing.

Looking at the heli from the BACK, I am trying to make both servo cables go from the front two servos, along the inside of the frame, and then out the back servo hole on the right side of the frame. (The empty servo holder).



Both wires will make it to the Rx now, but, the wire coming from the LEFT servo (Looking from the back) is touching the main shaft above the gears. The one from the right is clear, but is 2 mm away from it.

Am I doing something wrong here?



Difficult to see there, but you can see the 2 cables leaving the servos, and heading towards the back servo opening.

Hope someone can shed some light there.

[gazza]

You've got the wires routed correctly you just need to loop a cable tie through the frame where I have circled and tighten the wires against the frame with it. Make sure the wires from the servo to the ty wrap arent under tension though, just tight enough to keep them out of the way.

Hope this sorts it Oh and put something round the cables where they exit the frame to stop them rubbing. Some of that blue stuff maybe!

Here's mine...


Before anyone says anything I know the servo arms are wrong just not had any reason to change them yet. Too lazy to do because I should as well

[gazza]

Sod the Servo arms thats a marvellous kettle

Out of interest Phil, what sort of duration should I be looking at using 2170 mah packs and 12T pinion with standard 430L motor.
Been timing my flights and landing at 6 minutes to be safe...

No 3d just yet

[Cralis]

Aha! OK, Thanks Gazza.

Rerouted that way again, and it looks good. Put a tie on, but now my worry is that the servo arm is MIGHTLY close to the ties 'Locking square'.

Here is a front view. Notice how close the arm (or what ever the thing is called) comes to the tie on the outside of the body..



That is looking fron the front, along the left side (as you loof fron the front) of the frame. Is that OK?

Here's the side view:


Those ties are pretty small. Maybe you get smaller, but these are the smallest I could find. In the photo, they look large...

If I swivel the server all the way up and down, it doesn't touch the tie...

Safe?

[Cralis]

PS: How do you attach photos?! I'm having to upload to my web server, and then add links!

[gazza]

If it doesnt touch then its safe mate
My Raptor 60 pitch bellcrank and roll bellcrank were as close as that by design so I shouldnt worry.
