Sounds like you had a DYNAMIC BALANCE issue. Main rotor blades can be STATICALLY BALANCED but once they get moving if the c.g. of one is way off from the other then once you hit a certain headspeed (rotor rpm) that imbalance can and will cause that shaking.
p.s. Crashed my T-Rex today
What's the story on the Trex and what's the damage report $$ ?
Both rotor blades = $12
Feathering Shaft = $6 (pack of 4)
1 Blade grip = $7 (pack of 4)
Total cost in parts = $25 = CHEAP!!
Got it back together in less than 20 mins and was back in the air again!!!!
What caused the crash?? A brain fart. Was doing some lazy piroettes and ended a couple of them nose-in. Heli decided it wanted to go left and out of reflex I countered by giving right cyclic (nose-in I should have given left cyclic) and it went into the ground sideways. Luckily I dumped the throttle just before it hit.
