I'm at a complete loss (what with not really knowing how to mod actors properly, but working it out as I go along) for how to increase the power of jetpacks so that heavier stuff can actually fly. I thought that maybe inreasing the number of particles from a jetpack would help, but I can't actually find the place where Jetpack data is located (everything is copyof = Jetpack/HeavyJetpack etc and I can't find these) I'd rather have the data for each actor that I make contain the jetpack in the same file as the actor itself, so it'd really help if someone could explain how to make them more powerful and possibly post the code for a jetpack, so that I can include it.

It's in base.rte/effects/pyro/pyro.ini. Search for
