    Andy replied to a thread Luna-Tic improvments in Featherweights
    For the base, id say if it is a structural member of the chassis stick with thickish hdpe, if it is only really holding the internals in then 5mm hdpe or 3-4mm alu would be fine

    A dab of hot glue between the servo lead plug and the receiver is usually enough to hold them in, but easy enough to peel off if you need to remove the plugs at any point.

    Depending on your current draw, the standard is the Andersons SB50, or EC5 or EC8's. Silicon wiring is nice to use as its more flexible, but if not anything else works, as long as its big enough.
