I have experienced that on a 300CBI ( 269C) a few years ago, in dual commands with an instructor. i remember to had react quickly by increase colective to recover hover, then return to land and all was ok, my instructor told me that's the good reaction to have ...
A bit of an ignorant comment. Ground Resonance can occur in any helicopter with a fully articulated rotor system, including the $17 million AW-139 I currently fly. I simply used all H269 based models here as a level comparison.
The HU 30 (Hughes 300) helicopter is a twitchy little machine that needs to be actively controlled at all times!!! My first flights with this type of machine were thankfully with an instructor. I later moved on to the much more forgiving Enstrom F28 to complete my piston engine training before moving on to the much more powerful turbine machines.
I find it to be much more forgiving than most high performance and advanced rotorcraft. I thought it was a great beginner trainer. By the time I was instructing, everything was done in R44s which were capable of much higher performance. They were a bit much for new students.
this just confirms my theory that fixed wing planes want to fly, whereas helis just want to fly apart.
A fixed wing aircraft will cut itself a graceful path through the air where as a helicopter beats the air into submission.
Kudos to that student. Most students would panic and try to keep it on the ground.
How to get out of ground resonance.
1). Get it off the ground.
The helicopter gods were testing that student and he passed 👏

Helicopters are tough to fly.
When in Doubt…. Throttle out!
What did they all have in common?
They all occurred with that little egg beater helicopter.

You get what you pay for when it comes to helicopters
I agree with you in a way. I got pretty damn good training, but it also wasn't cheap.
