@ actionplus   man that is looking good. We will have to fly soon so we can have 2 yellow jackets in the sky!

 

Got my Gemfan wood props. Very high quality and even better finish. Did a test hop in the driveway and it looks like the first wood props that produce no jello for me.

 

I love the black and yellow!

After 4 weeks of "no fly", I have finally sneaked in a batt worth of time on the Ov3rquad. I say 1 batt, as I have the rest of my batts and chargers in the storage while I'm so called homeless :unsure:. Bunking in my brother townhome till I find a place.

Anyways, thought I will continue tuning the fellow a bit, but got lazy and just did a simple hover and little circuit over the parking lot to see if the gopro had any jello effect on it. Well, I think there is none or if there is, verrrryyyy little which I did not see yet. I'm going to the storage today to pick my charger up and get more flight in this weekend.

posting a gcode file is not necessarily useful as each machine has its "own behaviour" and this why we provide the DXF file instead. for a start I use mm and JC used inch. Then some units have tool change, flood coolant, etc. So if you look at the output section of a CAD system, you see so many specialised post processor files.

I use Mach3. I like it because it works, I have lots of support and is easy to load and run. I have heard that linuxCNC has come along since I started making CNC's over 10 years ago but there is still a bit of effort needed to setup, especially for servo's.

 

So I managed to dredge up our copy of CAMWorks and have been pounding through that as of recently.  Still feeling my way through it.  Since I've never cut G10 or really done much machining at all I was wondering if you guys had some speeds and feeds that you recommend for this stuff?  I saw a lot of people talking about taking two passes or so and then a finish cut.  I'll probably follow those same guidelines but was wondering what speeds you were running with what specific tools.

 

I have access to quite a few different tools in our machine shop but wasn't sure if anyone had any good luck with any ones in particular while cutting this frame out.  

 

Thanks for the help, looking forward to finally cutting one!

hi there. i've made jc final 2013 version and i came across one problem: the sides are higher than supposed standoffs. i mean the side and camera holder are 1.5 inch and 1.496 wich translates in roughly 38.1 mm wich is more than what i expected 37 mm and the djii arms are like 36.something mm. Is everybody experiencing this ? i mean i have to place a lot of spacers under the two djjii arm screws like 3 spacers or somethig. could this be fixed ?

I use G10 specific cutters. Also known as PCB cutters. Here is an example:

http://www.ebay.com....984.m1438.l2649

 

 

Sppeds and feeds depend on the machines ability. My unit will allow me to cut 1500mm/min, but i tend to slow it a little to 1000mm/min and I take 2 passes. I found 1 pass left the edges a little dirty which required more post work to clean. 2 passes leaves a crisp clean cut.

I've probably cut close to 20 units now and this method work well for me

The JC version is imperial and has 1.5" stand offs. You need to buy or machine 1.5" stand offs and then shim out the difference between the DJI legs and the bottom or top plate. I dont like this and so I drew up and cut a file that hass 37mm side walls. No shims required. However, this means that I spend 1hr just in making custom stand offs (14) for my frames and then the 30 minutes to cut each frame. So it is a lot of work, but the product is better. Having said that, I expect Luis does it this way to keep the cost of the unit down as each unit probably costs me money if i were to charge for labour.

 

Search the thread as I did post my version of the file with the 37mm side walls. You can take the walls from this file and just cut them again. But as i said, you may have to make the stand offs as I couldn't find any at 37mm.

 

Good luck and please post pictures

yeah, well i will see. i will just go with is as it is and see what happens :) i will go to one shop and make myself some 38.1 standoffs from aluminium rod. Here i can find only plastic ones or metal(wich are way to heavy for my liking) But overall it is a nice frame and i will post some pictures after build.

I asked to a friend to make PDF from DWG on scale. If someone need it to build this frame in Wood, here it is the PDV version of 1-7-213.

 

To check if scale is fine: The retangle of GoPro on Layout2.pdf must have ~ 42mm x 60mm.

 

Cheers,

Thanks to seafurymike another ov3rquad will take to the air. Slow progress at the moment assembling it but that's ok because this will be the "nice" quad in the fleet. Normally I'd solder up extensions for the ESC leads to reach the power distribution but for this one, I want to get the cabling nice and tidy so I'm making custom length ESC leads for each one.

Should be a nice home for the future Revo :)

Nice. Looks pretty stable and smooth. What's your hardware setup?

Looks like a nice open area to fly too. Is that around Pakenham?

Thats the way Haych, give those seagulls a hard time!! The overquad seems really well sorted and stable. You flying that in rate mode or attitude?

Cheers, I like the frame, this is my first attempt at FPV flips in the Ov3rquad, its a perfect place to fly if you don't want to look at anything exciting... Yep, its just on the edge of Pakenham, we don't bother anyone around there, the police often stop by to see what we are up to but soon leave us alone when they see we are harmless drone flyers... ;)   my big boring brown paddock is now a big boring green paddock...

That was all rate mode, it bobbles around a bit after the flips though... cant do anything exciting in attitude mode on Naza as it limits the angle, I tend it fly rate mode for fun, and attitude/gps mode for stable hovering (mostly when taking off and landing) I still haven't bonded with the CC3D yet, I need to spend some more quality time with it...

Is anyone selling the frame plates and spacers for the ov3rquad?  I would really like to buy one but I don't have a CNC machine nor do I know anyone who has one that I could use.  If someone could give me a quote via PM for cutting the plates and spacers that would be pretty cool.

thanks mate, but Naza doesnt give me any D adjustment, I need to tune the CC3D next instead of mucking around with this Naza thing, I will need help with that Im sure.
