How to Helicopter?

[Sauron]

Playing with Firespitter parts, but I'm at a complete loss as to how to make this thing fly. A: I don't really get the controls, and B, despite having enough thrust (more than enough) to lift a 20 ton helicopter, the usual tail rotors, etc, I can't seem to make this thing fly--it starts turning and doesn't stop, and I have no control whatsoever over my pitch. Halp? Thanks!

Are the center of mass and the center of thrust aligned?

Even though I've never tried helicopters in KSP, nor the firespitter mod, I'd say try removing your tailrotor, you shouldn't need one with two main rotors.

Which way does the rotors rotate?

Same here, i would suggest make sure that the main rotors counterbalance each other. take for example a look how rotors of the Chinook rotates, one turns clock-wise the other counter clock-wise too cancel its gyroscopic effect.

The Tail rotor in this setup prolly would work against the design, and would i would expect in a RL design make the helicopter spin.

Tail rotors are needed is signle Main rotor designs too cancel the gyroscopic effect, in this case the dual main rotor setup would allready making this effect dissapear.

But again, i never played with this mod, just making observations on how RL helicopters work.

Ya, so after testing it out, Firespitter rotors don't work like RL counter-rotating rotors--they work like every other engine does. The arrow just influences steering.

COM and COT are dead on at the moment.
