Satellite receiver - best location?

[Mart61]

Hi guys

Just wondering whereabouts on my T-rex 500 is the best place to mount the satellite receiver? And again, do you use any form of protection for the little fella?

Mines just stuck on the side of the frame with a sticky futaba style gyro pad and then a small align velcroe strap over it so it doesnt come loose. Just make sure the little aerials are pointing on a diffrent axsis to the main unit. This is to maximise range.

same here.... stuck on the bottom of the servo tray with a sticky pad and a thick elastic band to hold it .

Thanks guys - that sounds like a plan.

I have a similar setup, I also put fuel tubing over the ariels onto the case of the receiver (its a night fit) to protect them

Sorry for the noob question but what does a satellite reciever do?

This might help Martin...

Most of the SpeKtrum Rx use one, some can use more, for specialist applications. Due to the short wavelength it allow the signal to be 'seen' by the Rx even if one Rx becomes shielded for example by Carbon Fibre. To be doubly sure its also recommended they are orientated differently and spaced apart a min of 2" from memory.

IMO dont mount it like Eddie lol
See how both his sets of aerials are running along the same plane? (horizontal)
Well i would have turned his satellite 90 degrees so the aerials are going up and down in a diffrent planes to the main unit in between his frames (ie vertical). This will give you maximum range and its designed to be like that. Some people dont bother but if ya want things to be proper then thats what u need to do
Sorry Eddie hope that doesnt sound cheeky

Havent got one of my 500 without its canopy on but heres a pic of my old knight 3D (see how the aerials of both units are on diffrent axsis?) Also notice the thick padding underneath both RX units? I think it was CSM gyro mounting tape i used on that one but you can buy rolls of the stuff which is the same thickness.

Thanks again for the input and pics guys. Much appreciated.

Hi All,
I don't think that the way Eddie has mounted his is wrong since the aerials of both Rxs are in a different plane.
Obviously there are 3 possible planes (we live in a 3 dimensional world) there is the 'X' axis, 'Y' Axis and the 'Z' axis.
Eddie is using planes X and Y whereas Lee is using axis X and Z.
If you had 2 sattelite rxs then you could cover all three axis.
The only thing wrong with Eddies mounting is that the main rx aerials have been bent back along the same axis as the sattelitte Rx.
If they were straightened then they would be OK.

Yes I quite agree. different planes is the key -if Eddie rotated his satellite so that it was vertical, as soon as he pointed the heli nose up/down, it would be horizontal anyway!

Might be 2 diffrent axsis in a 3d world mate but Eddies (sorry for using you as an example here by the way bud) is still in the same horizontal plane whether its X or Y. This is because when the orientation of the model changes then you will always have the 1 unit in the horizontal plane and one in the vertical plane. If there mounted in one plane then the model say goes into a vertical dive or climb then that axsis will change because his are mounted in the same plane. So what happens if the signal is blocked for that particular plane (lets say the whole horizontal plane)? This is the whole point of having a satelite RX surely? It will work either way but what im saying is it is a little better mounting them in 2 totally diffrent planes because both units are seeing 2 totally diffrent environments.

I don't really want to labour on about this as it is essentially correct either way.
He has mounted in two different planes just as you have.
Its just that his two planes are in X and Y and yours are in X and Z.
If he points his heli up or down then the sat rx will be pointing up and down and his main rx is pointing horizontally.
In your case if you tilt the heli so its on its end then both aerials are in the horizontal plane!
The only thing wrong is that Eddie needs to straighten his aerials from his main Rx so they stick out the sides.
