    top 10mm SHOULD be fine (as there is new gen nasty axes coming)
    I would normally agree but after Manchester, I've revised my opinion. 10mm is OK when paired with something else, such as a hardox wedge laying over the top of it. Then again, no axe got through the lid of The Honey Badger 2, it had to be ripped off. I suspect that is more down to the way the panel was anchored to the chassis though rather than the material itself.

    Yeah thats a good point, how is the best way to attach HDPE panels together? Would have assumed just screws? Maybe angle brackets/blocks?

    Hence the Should XD, for armour that will see a spinner get something a bit thicker, but saying that i am currently helping AL_ find a place to make a Ti ram for pressure point so it can be armoured up. that can go through 10mm like butter

    The Honey Badger 2 used 3 blocks of wood to attach the panels to. It is positively archaic :P I would bolt straight through if I wanted to secure it properly or use threaded inserts.

    You can screw HDPE together, however it does not hold the thread very long, the thread deteriorates each time you take it apart/put it back together and its generally not the strongest joint. Threaded inserts or barrel bolts will give you a much stronger joint and both can be both cheaply on ebay or the like. Lots of build diaries on here showing those types of fixings. Angle brackets or blocks with the HDPE bolted to or through them is another option. Easy to do and if done with some nice beefy pieces of metal can also give a good strong joint, at the expense of a bit of added weight.

    Verily, this is how I mounted the axe mechanism to The Honey Badger 2. Some big ol' M6 bolts through the panel though I should have used Spring Washers I think.

    I can get hold of wood easily and a guy at work can cut me the pieces I need so using the flip bot base and rear/sides going to get something working and moving and once I have all the electrics running can look at a more durable design and the HDPE pieces, ordered some samples of HDPE so can have a play with those.

    The RW guide mentions a "dual RC switch" what sort of switch should i be getting for that?

    Just need that and the ESC and then can get started

    Can you provide some context for this (perhaps a quote with this phrase in)? A dual RC switch, when I search for what that was, came back as being either as a literal switch controlled by the TX or as a ESC.

    Not got the book with me at work but on the layout diagram it refers to it as an "RC Relay" shows that along with the ESC and receiver
