550 3GX placement

[CW.]

Hi guys,
Im about to start building my 550 V2 3GX, looking at the instructions the 3GX unit is placed upside down under the mounting plate (below the boom block) is this where everyone is putting it?
I only ask because it looks to me that it would be impossible to get to the setup buttons and pots in that position.

I put mine up top as per 2nd placement location in the manual

Simples!
Cheers, I did see the other plate position up top. Just the diagram shows it underneath, and photos of other 550's seem to have them underneath too. It does look better down there but would be a pita to set up.

put mine on a extension plate made from scrap carbon. cyano' ed below rudder servo, with wires going into body. This way i didnt have to change orientation settings and can plug in usb lead for updates and can access button and see light. No problems to date

Not sure if this applies for the 550 but on my 450 I was told to try under the main shaft as it was less likely to take a hit in a crash and it was closer to the centre of rotation (although for roll pos 2 would seem better). Doing the setup was not too bad as the button is still accessible but was a pain to see the lights (ended up using a mirror)

Hey.

On the carbon plate fitted in the frames above the boom block, or i found mine was best on the lower carbon plate between the under carriage struts and behind the motor. Near enough directly under the mainshaft, for no other reason except it seemed to get less vibration there i felt.

Thanks guys,
@ coolice, how do you get to the setup buttons etc. with it in there?

It seems my posts take a while to show up, they have to be checked by the mod first , dont know how long that lasts?

Hey buddy.

Well there are 2 ways really;

1. A soft, pointy screw driver. Or
2. A very bendy little finger ;-) lol

Either way needs a keen eye to see the led labels, but as you only really need to get to the button 2 times its not too bad.
I then leave the dongle adaptor lead in place for pc connections.

Cheers mate,
As said I haven't started the build yet, waiting till i can get my teeth into it properly!
Nice to have a plan though..

Had mine mounted above the boom, easy to get to everything from there. But also due to the fact I was using sbus - i mount the receiver in the bottom position.

Thanks for the pic sunny manku,
It does look easier to deal with in that position.

put mine on the cabon plate with the 4 tabs on and fitted it at the back just above the base plate if i needed to ajust i could just fit a plastic screw driver in or removed one skid screw and pulled the plate out

where mine is also.

Best place if you need to adjust the pots etc. in the bottom position you need to keep the USB lead in place, as you have no chance of getting it afterwards.
