Default Bad Vibe in Cal 30

Had my Caliber 30 out to the field yesterday. I am a noob so I have been getting the assistance of some experienced Heli pilots. Unfortunately nobody with Cal 30 experience. I had them hover my Cal to get everything trimmed and set up. Trimmed up beautifully, Heli would fly "hands off" for awhile. Put Roto Pod training gear on and another pilot hovered the Caliber to trim it out with the training gear on. He got things trimmed up with the gear on. He then attempted to hover again and the Cal 30 started shaking like an 'ol dog trying to pass a peach pit! Low frequency vibe which was really evident through the training gear. Had some excitement, vibe shook rx battery loose and it came disconnected so we had a runaway heli on our hands, luckily it just sat there at high throttle on the Roto Pod spinning away for 15 min. until tank ran dry. Thank goodness no harm to people property or Heli.
Couldn't find anything loose or bent. one min was hovering nice and the next bad shake. Any ideas?
My fellow club members advice was to get a Rappy
Thanks for your input

Some people have this problem wih training gear and they make it shorter and it lessens the shake. Another eason that is just my 10c (because now we don't have any 5c) is that the training gear isn't attached perfectly to the center of gravity...

It's most probably the training gear finding it's oscillation frequency..... Unfortunatly for you it's at your hover speed! Try increasing or decreasing the hover speed. Have you got fine tuning sliders or trims on your transmitter?

Don't get a Rappy..... Everyone's got one

it's most likely the training gear, I had problems with mine when I was learning and just shortened each rod a few inches..if that doesn't work you should maybe try decreasing your headspeed.

Thanks all for the replies! I will shorten the rods and see if that helps.
Thanks,
