    Thanks W9GFO I didn't see any in the picture you posted earlier they are from a thicker material than the chassis parts. Hopefully Ken will chime in.
    Fix it, if it ain't broke! .......... D Rat .......... Dave ..........

    If you look in the upper right hand corner, you can see the ends of a few. They are made of 1/4" Delrin, it measures 0.262" thick.

    I will admit that mine is still in the box it came in. Things have been very busy around here.
    While I have started to assemble mine, I haven't flown it yet because I'm still without a radio and battery. I guess I'd better order my Spektrum DX6i sometime real soon! :-)

    You are not the only to crash !

    Waiting for spare parts I found aluminium flat bars at the next DIY (2 m long* 2mm thick*15 mm width)

    Easy to cut and bend it works nicely to make a new landing gear and fly.

    Hey Kevin - I just purchased 6 of each type of propeller from Tower Hobbies and the accessory packs from Hobby King.

    Can you guys offer a package with ONLY your parts in it in case we bought the others from a 3rd party?

    I would want:
    2 - Top and bottom Delrin motor mounts
    2 - Landing Gears
    4 - 5/8" Nylon standoffs
    8 - 3/8" 4-40 Screws

    Or better yet, offer motor mounts with screws and Landing Gear with screws, etc as individual items to buy?

    I agree with kmc123 on offering the parts you make in smaller packs. Like landing gear, delrin parts, etc, with the screws/nuts/nylon bits that go with them.
    Also, a Prop set pack.

    I think the most common things to need replacing are going to be props and landing gears, and I foresee myself having a huge pile of all the other stuff in the crash pack just because I need more props and landing gear bits.

    Also agree with kmc !

    I need only parts made by Parallax:.

    Beginning with the more important

    1 : Top and bottom motor mounts

    2: 5/8 Nylon standoffs

    3: 3/8'' 4-40 screws

    4: landing gears ( as I live far from California I learned to make landing gears in aluminium after i broke 2 Delrin ones)

    I'm ok with the single parts/crash pack as originally described.

    Anything that comes from HobbyKing takes a long time to get to me. And, I had to go to the post office to sign for it (Suggestion: Maybe Parallax could stock some of the ESC programmer cards too :) )

    If you start breaking it down into smaller chunks, it just means more work for Parallax. The Elev8 is not a major product line for them (yet?).

    Personally, I'm ok with getting all of the parts in it - but I don't need screws/bolts and standoffs. I've got plenty and I know where to get more (Microfasteners, Mcmaster Carr, Digikey, Mouser, etc.). I'm not going to ask Parallax to have a version that leaves these out.

    Maybe two versions would be ok. The one originally described and one with only Parallax-manufactured parts.

    I agree with everyone's comments and points of view. Like it has been said in previous posts, the ELEV-8 Kit is not as streamlined as we would like it to be yet. We are working toward making all parts available individually, so that if anyone needs only a few standoffs, or a Delrin piece, then you can order that piece by itself.

    Also, letting the cat out of the bag a little, but we have ESC Programming cards on the way, and will be available within the next couple of weeks. I will let you all know when we receive them, and when you can anticipate them being available as the time gets closer.


    For those of you who are in need of parts and the Crash Pack, it is now available for pre-order at the link below. They should be ready to ship mid next week. If there is a delay, I will let you all know.

    -Nick

    W9GFO or Whoever - Since you just cut a bunch of parts, you must know the answer to my question. I was just going to laser cut a couple things and figured I'd use the DXF files posted on Parallax. Downloaded those and as best I can tell they are pretty much worthless for cutting. I suppose I could redraw what I need from viewing those, but what a lot of work! Just wondering what files you cut from? I loaded them into Autocad and then finally tried Corel, but don't see how I can use what I'm getting. They make nice prints, but I want to cut!

    Thanks ...Tiger

    I can easily provide you with the file in Corel Format or I can export to dxf. Let me know which you need.

    For those of you playing with lasers, I thought I'd upload a picture of a mod I made to my quad tonight. I replaced the black delrin plate over the HoverFly board with one that's clear acrylic. I started out doing this because I'm taking the quad to a club meeting tonight and I wanted people to be able to see the goodies. Now that I've done it, I like it so much I'm going to leave it there. The acrylic is more than strong enough for the short span of the cover and I really like being able to see the connectors when I'm plugging things in. It also makes the LED very visible without the use of the light pipe. Notice how nice the lettering comes out on the clear material. You wouldn't think it would. No need for a second op with paint or anything else to make it visible. I plan to add a little more text tomorrow including the Parallax logo. I just couldn't find the file tonight. All of this and the material cost is less than half that of delrin! :-)

    That looks really cool! I don't have a laser, but my CNC should be able to do that just fine.

    Thanks to Cats92 I went down to the local hobby shop and bought 2 lengths of 1/4" aluminum tubing and fashioned my own landing gear while I wait. Kind of flimsy but I am back in the air again.

    Looks nice John! No reason not to use acrylic there since it is not structural. Same goes for the other piece underneath the board. I think I will copy the idea.

    Not structural? What do you think I use as the handle for my Elev-8? :)

    While it does look nice and costs a lot less to use acrylic it won't protect the board on a direct hit. We went with Delrin for this part based on my own experience with a crash that hit the board directly (most expensive part in the kit). Also, if you ever start using altimeters you want to keep direct sunlight off those types of sensors. Don't get me wrong, I prefer the look of the part you made but functionality is an important factor.

    Hi Kevin - I agree that the acrylic is not nearly as tough as delrin, but I really don't think it's an issue here. We're only talking about a span of about two inches. The acrylic is 1/8" thick (thicker than your delrin) and supported by screws in all four corners. Even if you took a pavement crash dead on, the screws alone would probably be adequate protection for the board. You might crack the acrylic where you wouldn't the delrin, but I'm not worried about a few cents worth of acrylic in a really freak crash. I'm guessing that in your board crash you probably didn't have any protection at all. Putting nothing on top would be a disaster for sure. I suppose if a guy was really worried, but wanted the clear properties of the acrylic, he could use Lexan. A piece of that a third the thickness of your delrin would probably offer more protection than you have now. Whatever... We'll be finding our real soon. My quad will we done in a few days and I plan to crash a lot! :-)

    Edit: As for the altimeter, I don't know what one they are using so I don't know if the issue is light or temperature sensitivity. If it's light, a dab of black paint fixes it better than a cover that's only on top. If it's temp, that's pretty easy to deal with to.


    All input welcome here. Thanks!

    i am making my platform from 1/8 light ply (actually 3mm) everything fit together nice and tight and required no glue to stay together. I glued them anyway. :)

    Hey Brian! Been waiting for these pictures - the first wooden ELEV-8 variant! It's a lot of fun to see people like you and Tiger using the drawings to make their own editions. I think we're going to see some serious improvements come out of this effort. I talked to Tiger the other night and I really like a mod that he's got in store for running the wires through the tubes - it'll be slick, I'm sure.

    Keep us posted on your progress and check in more often with photos.
