How would one of the Minicircuit Prepackaged can filters be?
My guess is smaller, lighter and more robust than what I can build.

I've been using some adhesive backed Cu and Al tape to shield things,
tried shielding the Rx, to no avail, but a front end bandpass filter
was going to be my next step.

This may be simple overload of the front end of the RC reciever. I
suspect it has little selectivity before the first stage and the tracker
unit is simply blowing through the filter.

It's been quite awhile since I did any RC work, but if it has a separate
Rx Antenna input to the RC reciever, you might try wrapping the reciever i
tin foil, and adding some high pass filters between the antenna and the
reciever. Make sure to shield the filters too, that much energy could
easily couple into the coils used in building the high pass filter.
