    thin heat shrink for 600mW VTX

    Hi,
    The heat shrink on my 600mW VTX is all cracked and pealing off.
    I have some really thick heat shrink at home, but I would rather find the same type as used on the VTX originally.
    Does anyone know where I can purchase this type of heat shrink.
    The closest I have found i think is, Ultra thin PVC heat shrink, but I could only find it in 100m rolls for 75 (don't need that much !!!)
    Cheers Lee

    Think this is the same stuff http://www.hobbyking.com/hobbyking/s...ear_1mtr_.html
    They measure the width of it as a circle not flat , I think
    Cheaper if it's wrong anyway

    I think I got that one. It works and it's clear but thicker than the stock one.

    Example of repaired vTX using it:




    This one is the same:

    Very nice. The SMA solder could be better if you add some flux solder but ok.

    Not really, in my experience the thicker the better after the trace is damaged.

    At RF doesn't mather the section of the wire but ok. I have noticed that the traces on PCB were designed with care so the LC network is balanced and proper impedance achieved.

    Oh, that soldering work is lousy.
    I wasn't in a good mood after it happened.

    Btw, any idea what these two componentes are, last crash made these fly away.
    I know the vTX is toasted but it was ok for some short range flying and bench testing.

    I would say 1.6pF capacitor and 3.9nH inductor, very sensitive stuff, hard to find. Those components are the most important.
