So, here it is again with the motors/props and electronics
Ok Mifau, please take a seat , you will scream when you'll see the noodle stuff on your sweet frame lol!
I'll clean up things later, I did it just to test the frame out..
So I used an MK fc with some turnigy plush 10A hooked up to a i2c to pwm converter from Timecop. As you can see, there's also a PPM encoder (and the rx on top of it). I also used a plate to be able to turn the fc 45° clockwise; I know I could have done it within the Mktool, but I already had bad surprises with that feature, so.. I prefer to do it myself! And too because the .mkm file is a bit special.. I did this also because there wasn't enough room on the top plate to drill the holes. But anyway it doesn't matter, if I'm satisfied with the flight, I'll redo a clean build
Regarding the motors, they are some rctimer 2208/12 1800kv with some 5" tri-blade props. Those motors are a bit heavy regarding the frame's weight, but as I already owned them I wanted to give them a try.
The lipo is a turnigy 3S 2200mAh.
I tried it in the living room and woow! the beast is quick! 'got to get used to it, as i'm used to 8" or 10" size props.
It's really not difficult to balance the frame, just by moving the lipo forward or backward, and it's okay I'm eager to try it outside.
Total weight (including lipo): 770g.
But I think I'll head towards the roxxy 2216/25 you use, because they seem to be as (or certainly more) efficient for half the weight of those I use. It will be a plus.
So far, I'm happy
Cheers and I'm gonna post a vid of it's outside maiden flight

This is not a scorpio now, but it's a spider
But ok... for the experimental purposes it's OK
Weight is quite ok, don't worry.
Frame is designed to have motors installed under these "ears", but I think that it will fly just fine like this.
Heavy motors will weaken "ears" so you have to be gentle with hitting ground
And just remember to balance props!
Nonetheless....congratulations, it looks it will FLY!
You have put lots of work here. It have to fly well
So, I'am eager to see it flying!

Today I made some photos of scorpio frame accessory... GoPro Home
It can be easily mounted to the frame...and... just look at the pictures.

Excellent! This would be a good complement to the frame
Please keep me posted about availability..
Right now I'm rebuilding completely the electronics, and have ordered some robbe roxxy motors; they are somewhere between Germany and France!
Does anybody know where I can find some 3-bladed 5" props? I have only six of them, and I don't remember where I bought them, a long ago.. Any idea?
|Nov 07, 2011, 06:07 PM|
Yep, I flew it as a test outside and it did pretty well! But I've just received some robbe roxxy motors, so I'm gonna swap the rctimer ones with those. They look really tiny and light, they certainly will fit the frame a lot better.
Do you plan to make a 8" or 10" props version of that frame?
Video coming soon

I just have to think how to install motors to arms...
It cannot be made as in mini frame, because these "ears" are to weak for bigger motors. Direct mounting motors to arms is also non good idea, because of frame profil height....

Thank you for the DFX file. I will use it for scaling up around 14" props some day in the future. I was wondering what if this is scaled to use 4" props with a 4s setup.... Would it still be able to carry the gorpo? I am planning a trip to an exotic country and the smaller the better to fit in the suitcase
Very nice frame though really liked it.... In fact i doubt i ll sleep through the night now...... I think it has better functionality against the frame shrediquette.
The Fov is very good. You barely see the props in the video.
I was also going for those roxxy 2816/25 motors but since my goggles are broken and need to buy new ones i guess they ll wait. I am also going for the ones on giantcod.
As for CW and CCW 5x3x3 GWS props try here

4" props will not lift GoPro
But I think that it will lift some light FPV camera with small video TX.
Yes! Shrediquette (Willi) was my inspiration with that frame (As can be easily seen).
I had to make longer front arms to have wider FOV.
As I said... feel free to use those plans! It's a pleasure to me that someone will use them

Unfortunately local laser cutting donesn't even now what FR4 is so theres only one way.... The Cyberdrones way!!!!
2 more questions though.
1) I currently have the kkmulticopter board. I want to upgrade to cyberdrone FC at some point but i am not sure whether the FC mounting holes will match the ones of the kkmulticopter to be placed 45 degrees right or left since it is a X configuration platform..
2) I am about to order some batteries.... 3s or 4s? Would 4s provide more flying time?

It all depends on your motor-propeller configuration, and efficiency.
If you add some extra weight (going from 3s to 4s) and your drive configuration is ok for this extra weight than the will be some additional flight time (2-5 min I think).
For standard frame quadrocopter (40-50 cm from opposite motors shaft to shaft) I usualy choose 2200mAh 3S LiPo

I'm waking up this thread with a short vid of the flight of the Scorpio frame
So far, I'm very happy with it, especially with those 2226/25 roxxy motors. I was worried of using some 2200mAh lipos because of the weight, but the hexa handled it with no problem.
Lots of power and very agile, so a very nice setup for FPV!
The flight controller I've used is a TMF pro one. Works very good.
Next time I'll try some onboard video
PS: here's the vid:
