Is there a difference

Is the Cyclone a omni-directional version of the P-50 or is the P-50 the rotational version of the Cyclone since they sound the same?

There is no difference in the Cyclone and P-50, in that they use 50hp motors, and 8/12 choppers. The only difference is that the Cyclone is 125dB whereas the P-50 is 135dB at 100'.

Speaking of the tone frequency, listen how deep the low note sounds on this P50(RM 135, 1st gen T135) sounds! That is a very penetrating tone! That probally travels far.
