I need some help making an invisible propellent for, say, a helicopter. I've got the particle emitted being invisible, and the lifetime is set to 1, but if I increase the mass to where it has to be, the rocket spins around and sometimes explodes in midair.

Hope I'm descriptive enough.

Make sure the main thruster is centered on the X axis of the craft (Offset X = 0). Also, adjust the positioning of the side thrusters. The closer they are to the center of the craft, the less control the craft will have.

actually for stability you'll want 2 emitters in line vertically but as far apart as possible horizontally, but equal distances apart from the center of mass (I think the center of mass in CC may be the sprite offset).

sprite offset is the rotational center of the sprite

OK, I fixed it. Look forward to an Apache delivering your troops.
