"Using such a remote control would be pretty “risky” in the sense of premature detonation due to the presence of other radio signals in the area."

I thought the receiver was identified as a 2.4 Ghz unit from a hobby-grade R/C helicopter (I own similar). If so, the DSM-X or DSM-2 receiver is bound to a particular transmitter and is almost invulnerable to common modes of interference or jamming.

Just How Good is DSMX? In multiple tests, 100 DSMX systems were operated simultaneously for extended periods of time. During these tests each of the 100 systems was monitored in flight and on the ground. In every test not a single case of RF link loss, latency increase or control degradation was experienced or recorded.

If that's true, and I hadn't heard that, then yes, it's very doable. Not quite as dangerous as the 47MHz receiver, and much more reliable.

For my Raptor Tiger helicopter, I'm using a Futaba 50MHz radio, but I had to send them a copy of my FCC license before they would send it to me.

I wanted a frequency that others on the field wouldn't have.

I would be more worried by accidental RF from unknown sources i.e. other radio services that might be present.
However, I’ll take your word on the new stuff as I haven’t done RC in over 15 years.
The other though that occured to me in some of the discussions on this thread is that there wouldn’t be any need to worry about the metal pressure cooker blocking the signal if you taped the RC device outside and just routed a couple of wires into the detonator inside.
I haven’t definitively heard what explosive was used?
