tricopter? NO! tri-helicopter!!!


I hit on today,if I made tri-helicopter,I need not cope with main rotor torque.
So,it's enough buying 3 MINI-CP,need not buy 4 MINI-CP,I am lucky!

I don't understand your rationale. By "not cope with main motor torque" you mean no need for tail rotors? In your drawing you have them, and I think you do need them, regardless of configuration.

My English is too bad,I'm sorry.

In the case of quadcopter, running torque disappears.
But as for the case of tricopter,torque remains by one rotor,so a mechanical rudder is needed in order to erase it.
It is a little troublesome for me.

But I will build multicopter using by HELICOPTER,so I only need 3 helicopter,not need 4.
It is very simple.

I can understand a quad does not have torque, because two rotors are spinning CW, and two CCW, thus cancelling each other. Are you planning to mod one of the three heli's to have opposite rotation? Referring to your drawing, I can see that if the two rear helis' rotors are spinning in opposite directions, then only the front heli would need a tail rotor, is that what you are thinking?

just as drawing,3 helicopters has tail rotaor as usual,main rotor rotation of 3 heli is same.

just only connect 3 helicopters.
