I have think about that too.
Putting the weight lower to the center of gravity could benefit.

Just a bit harder since you need longer landing (which add weight on tip of arm … which is worst than the camera thing)
I fly a similar design and really … no problem at all… lol
You can’t see it the pictures but there will be a CCD camera under the plate for FPV (First Person View).
Also remember that the props are higher than the top plate…

222

Yes i see your point. G10 is quite a heavy material. Plus i like the length of the landing legs so another reason not to lengthen them. :wink:
8)

223

Here is another SpyderQuad i made.
Taller landing… smaller center plates… And it was using some hand made acetal boom clamp.
Those where hard to manufacture and time consuming…

But i like the new one much better… :wink:

I wonder if you can buy inexpensive Carbon/Kevlar like 3/16th inch thick sheet then machine it from there?

Honestly I would love to buy one of those frames from you!

… You need to get skype I have some questions for you about my quadcopter… since yours ovbiously lifts off the ground for more then 3 seconds without failboating.

I can buy cheap carbon fiber sheet…
On the way to have a link in US to buy a good price. Also would like to setup a water bed for cutting carbon.
That particular model use 1.5mm for everything but the bottom plate which is 2.4mm. But G10 Glass fiber sheet.
It take a complete sheet of 12x24 inch and some more for the bottom plate.

I do have skype… :stuck_out_tongue:
Use a lot for work.

Hey, What size are those boom clamps? I could probably produce some to your spec for pretty cheap.

229

That one use some already availible clamp. (For that customer)
I have my own which i make 3D print but they are a bit on the high price… so people don’t want them.

Here is two model

And an assembly on my Spyder FPV QUad

Which material you have in mind ?
Cause i tried delrin and it’s the worst material … to slipery

230

I was thinking microballon filled polyurethane. Very light and definitely stronger than a 3d print. I could probably make them for around a buck a piece(?) . Ill check it out. And they’d definitely be much grippier than delrin.

231

My last little baby…
DiaLFonZo-Copter MiniVTail … :wink:
Fresh from the new cnc … !!!

Assembled quickly to confirm the fit of parts… then packaged

Very nice kit!

Your design?

233

Loving the color scheme on that. Ill order one… its about time. :wink:

234

Of course it’s mine… :wink:
It’s the Mini version of it’s big brother in 400mm and 500mm

Here is a 500mm

In flight… :wink:

235

Beautiful design! Ever consider incorporating small wings and pivoting props ~the V22?

236

Thanks… :wink:

Well, i am kind of limited to what the controller can handle.

237
  1. What’s the weight of the frame for the 500mm version?
  2. What battery do you use (voltage & capacity) and how long does the copter last under average conditions?
  3. Which controller? Ardupilot? (my apologies if you said what it was in a previous post).
238

Weight of the frame without any electronics on it (sorry for my oh-so-nice scale…)

I have not fly the frame a lot myself… just no time.
There are many sold and they are putting info on the RCGroups thread (rcgroups.com/forums/showthre … st21161449)

Battery would be around 3000mah 3S LiPo (or similar depend on which motor you put on there)
500mm is for 10" size prop and 400mm is for 8" size.

The most popular controler would be a Multiwii based controller or a KK board.
I have see both in nice flight on the thread.

One person did it with a DJI Wookong and custom setting to get the VTail setup.

239

Pretty cool looking. You have been busy up on the RCGroups with over 5000 posts! May have to try one some days…

Yes i am more active on RCgroups than here.
Mostly because i am better at making Copter frames than i am at programming robots… LOL

But throw me any design oriented project and i can do it for you… :slight_smile:

I would stay away from a VTail quadcopter for the first copter.
This thing have a LOT of yaw authority… And it’s a bit tricky to dial the PID value to have a good flight.

But here what it look like in a PRO hands…
