    Hello,

    I recently moved from a DX8 to a Graupner MX-20 with the big GR-24 receiver. With the Spektrum I used to mount the receiver in a boom of the CS8 but if I mount the GR-24 the antennas wires appears on the camera when I rotate the gimbal.

    I know I have to mount it on the frame, but I would like to hear some suggestions of location and position for it and its big wires.

    Thanks,

    Hi Arthur,
    I have mine mounted on top of the center plate on the open section next to boom #5 (the back boom). In the photo below, I'm using a GR-16, but I've had a GR-24 mounted at an angle. I didn't notice the antennas in my footage. To mount it, I used 3M double sided foam tape. It's super sticky, and able to be trusted when it's used to mount something with small contact points.

    Thanks for the photo.
    I'll try that. I was worried about the receiver signal and the carbon frames, but since you are using it this way, it must be ok.

    Sure thing. I haven't had any trouble with it thus far.

    I mounted my GR24 vertically so that the "rabbit ears" antennae are pointing upwards to correspond to the orientation of the antenna on the MX-20 -- and to better ensure that the side lobes of the radiated power for the GR24's telemetry are likely to be horizontal rather than vertical.

    I located it between booms #1 and #8, so that, given I fly nose out (which I do most of the time), if the signal gets weak, I have the option of rotating nose-in to get better line of sight back to the MX20 to bring it home.

    The two cable ties still allow me to press the button for Rx binding. I'm tempted to add some foam cushioning as the GR24 is in hard contact with the frame and the associated vibrations.

    Hope this helps.
    Andy.

    Hi all, just my 5 cents worth. We placed our GR-24 standing vertically as per Andy's, but we mounted ours within the framework between booms 6 & 7. Using the per drilled hole in the frame and securing it in place with a single cable tie as the frame stops it from moving left or right. No problems that we've experience with reception so far. I took a piece of sanding paper to just take of the very square edge on two of the sides and it slid in quite securely.

    The material selected for the "rabbit" mount was plastic to prevent RF blockage. It is easily collapsible by removing the o-ring which is a FF silicone ring. Sorry, no data on range improvements at this time.

    Are you still able to fit the velcro strap through to hold 2 batteries?

    Do you use the outermost slots, Josh? I find that I use the narrower next-inboard slots even for two batteries.
    Are you putting the batteries "across" the battery plate -- that is across the short axis of the plate?

    Andy.
