Some Lego spaceships have handles attached, made out of Technic beam and pegs, and attached to the model using Technic bricks, pegs, and axles.
This handle is great for play, transport, and mounting, and I'd like to incorporate this feature into my own designs. However, I don't know what a safe number of pegs and beams is relative to the weight of the model. To be really useful, it needs to support not just the weight of the model, but a reasonable amount of centrifugal force caused by rapid course adjustments as it flies around my living room. Are there official Lego Group guidelines on this, or has someone done a study of the strength of peg-and-beam constructions?
