Hi Folks,

Apologies in advance for a simple question. I have noticed on a couple
of postings that there is a counterweight on the front of the main
shaft. If this is to counterbalance the eccentricity of the rotors, how
do they accommodate two or even three rotors, since I assume they are
offset? Is the balance a compromise on a multi-rotor engine?

In a single-rotor engine, is it possible to fully balance the engine
using this counterweight? Or would the counterweight need to be
excessively heavy?

Thanks in advance,
...Now back to regularly scheduled reasonable questions :-)
