I'm not knocking the BK117....it's one of my favorites. I was just pointing out that the bell works best with linear control, unlike most others. For yourself, Nicola_M, it's a mute point, because you got rid of your bell. For anyone else, trust me, the bell flies alot better with linear control. Conex tells you in his manual to set it up that way. James Hetfield, that is very interesting. That looks like an affordable way to have a good cyclic control. I'll have to take a look at the Warthog.
