    TBS already has a GoPro and cam box, just picked one up for the TW40.
    They do sell battery boxes for the Z1, 4s/3300 sized.

    I ended up buying some basswood at hte local hobbystore to make mine.

It was rather frustrating. Now I've starting buying 5000mah Zippy's instead since they're about the same size and weight with more capacity.
    Yeah, I was thinking (worrying) about that too. I know HK's weight specs are usually off so its no surprise the dimensions would be too. The other thing is that batteries puff as they age and/or you abuse them (disclaimer: I abuse mine!). So making the boxes a little oversize would be good... I'd prefer to have them a snug fit but there IS a strap for a reason I suppose.

    Are your 5000's "short" enough to fit in your wings profile or do they protrude? I've seen a lot of pics of wings with the batteries protruding a bit and I guess the owner isn't as worried about aerodynamics... or as anal as I am (also, what wing are you using? Deep Reaper?)

    One thing I didn't like about my prototype was that the cutout for the wires weakened the box, so I'm going to increase the length a tad and have the edge of that piece come back up so the edge has more contact area on the end piece.

    I'm using a Deep Reaper, and yeah my batteries protrude a little bit, but it doesn't seem to really affect anything.

    Nop, they don't produce the Battery box for the ZI anymore... I asked Trappy when I saw they disappeared from the TBS Store

    BTW I'm looking for the Battery box of the old ZI aswell, I have the Nano Tech 4S 3300 and the RMRC 4S 3300

    Definitely a good idea though I wonder how much you could make.

    I wanted some for my EPP wing and since nobody was selling them I made some myself. Cost me about 12 to have two battery boxes and an electronics bay cut at a local laser cutter which I did after about 3-4 hours learning Google Sketchup.

    So here's my short list so far categorized by Wing

    Popwing/Teksumo
    2200mah 3s

    Ritewing TW40
    ??

    Ritewing Zephr
    3300mah 4s (single wing tanks? Or a dual battery central box?)

    Ritewing ZII
    3300mah 4s dual batt central box

    Deep Reaper
    4000mah 4s to 5000mah 4s (single wing tanks? Or a dual battery central box?)

    There's lots of other wings out there (feel free to suggest and I'll add to the list) but I think I'll start with...

    2200mah 3s single
    3300mah 3s to 4s single
    5000mah 4s single

    3300mah 3s to 4s dual box

    The Deep Reaper generally uses two separate battery slots with one on each wing. I also think I'm the exception using 4s on it. Most other people use 4000 mah 3s I think. Mine is a heavier more powerful setup than usual for this plane.

    I think just make single boxes which can be combined together to make dual box. Shouldn't be hard to design it such a way that 2 boxes can be interlocked.

    Oh okay. Well, in most cases 4s batteries of the same mah are just a little taller, so I'll make the box match the height of a 3s and if people use 4s then the battery sticks up a bit like yours. Was thinking that it'd be better to make it sized for a 5000mah... that way 5000 and smaller will fit, someone using a 4000mah can just use the battery straps... and/or add a strip of epp from the scrap to make the battery snug fit.

    Yeah that's a good idea!

    And... the moment you've all been waiting for, lol. Got the first 3 "standard" sizes, in bamboo and plywood. Ran out of room to cut the dual battery box so that'll come with next weeks batch. The plywood came out a tiny bit lighter, a little bit cheaper but more importantly, a bit stiffer. Also, there's less of a grain problem so the plywood won't split down the grain like the bamboo "can" (it CAN, but I haven't had this happen in any of the projects I've used bamboo for, so...). So plywood would seem to be the winner here. The other thing is that these boxes will get glued into epp wing cores so its not like the aesthetic qualities of the bamboo will really be needed

    When I was over at pdxDave's looking at the RMRC batteries I noticed that the balance plug comes out the opposite side as the power wires, unlike turnigy or zippy where both came out the same side. So, I put a cutout for the wires on both sides of the box, this could also be helpful if you put your plane together and then decided you wanted the power wires to come out the other side to make the wires "just long enough."










    Plywood 2200mah 3s


    Plywood 2200mah 3s - With cutouts to see how much weight can be removed. Now that I think of it, you won't want the cutouts on the bottom if the box comes to the bottom of the wing.


    Bamboo 2200mah 3s - With cutouts


    Plywood 3300mah 3s to 4s


    Bamboo 3300mah 3s to 4s


    Plywood 5100mah 3s to 4s


    Bamboo 5100mah 3s to 4s


    So now that plywood is the victor, I'll work on my game of tetris and see how much they cost to make and work up pricing for them.
