Multirotor, multicopter and quadcopter discussion - The Drone thread

That volcano video is awesome !!

I finally got round to buying a case for my Vision. It wasnt the one I linked to a few pages back as they had sold out. I bought this one instead.

Is there a guide/template somewhere that you use to make the holes in the foam for the aircraft, or is it a case of just drawing round it with a pen then cutting/plucking it out?? :confused:
 
As mentioned the other day, been planning a quad in 3D since I'm pretty indecisive at doing anything practically! Allows me to play around with layout.
Currently looking like this - was wondering what people think.

Plywood Frame, Carbon Fibre arms. The arms pivot on bolts, my thinking is that with a combination of the softness on the wood and tightening the bolts before a flight they'll be plenty rigid enough for actually flying, whilst having some give should (when) I crash.
The carbon fibre bar along the top is just to offer some protection to the Flight controller - have bent the pins enough times already on my KK2.0!
Mobius camera fits in front of the battery at the front, Receiver at the back.

Need to ponder over the wiring to check it isn't going to be a pain. The cabling from the speed controllers to the motors actually works perfect at the moment with the current lengths - saves me re-doing the bullet connectors. Will have a lot of slack on the signal cable though, but I'll just tie that up somewhere.

Any comments / criticism would be awesome :)

looks pretty good,if your thinking of using the carbon fibre 10mm x 10mm tubing for the arms (hobbyking) its not very strong, goes out of shape very easily.

I built my mini 250 with it, but soon changed to 12mm x 12 mm wood as all the arms got distorted over time.
 
Cheers for the comments. Yeah I'd been looking at the Hobbyking stuff, I guess you do get what you pay for there! I guess it is at least really light weight. Might still give it a shot anyway but look to get some wood for the arms also, both will work in terms of design - plus there is always Aluminium or sourcing some better CF :)
How bad would you say the HK CF actually is? Are we talking really fragile and a little flexible? Or just not quite meeting the rock solid reputation that CF gets normally? - ie it won't be surviving heavy crashes.

Made a design change since those images already, as you might be able to tell (not hugely obvious) the arms are mounted on top of some blocks which are on the actual base piece (to get the clearance required for battery etc)
Have swapped it around so the arms are lower and the wood spacers are above. Makes it a bit more compact when folded up and won't really be an issue in terms of centre of gravity.
 
Any pressure like bolts holding the motor in place squeeze the tube together,instead of the hollow section being round it starts to go oval shape and eventually will split.

ITs hard to tell when the motors are on tight too,have to be very carefull not to apply too much pressure.

Wow, wasn't expecting it to be that soft.... Will have to have a rethink on my plans now. Might as well use some plastic straws from the sounds of things! :p
 
I spent today building rather than flying. I just finished the remote zoom control for my Nex5 on the gimbal. I've rigged up a continuous rotation servo to a belt drive to drive the zoom mechanism.
It works well, on the ground.

The S800 EVO is pretty much complete now.

Pondering some more over this. I figure I could just get some thin wood batten to sit in the middle to stop it being squashed where I put the screws through.
Let me know if that is actually a terrible idea though! :p

Looking online at box section aluminium as an alternative...

Did a full systems check on the S800 today without props attached. Ran it on full throttle for a while to check for any issues with the electrics. The ground station is awesome by the way.
I have got a small issue with interference on my AV2 channel of the iOSD Mk2 but I think this is caused by my sub-standard soldering on the connections.

Everything looks good for a flight test very soon.
 
Floyd can you send me or post up a picture without that carbon fibre bar on it? So I can show you my idea :)

Strapped a my old gopro to the tri earlier as I had some light left (mate has my hero3 so had to do with my trusty HDHero!) She flies a LOT more docile with the extra weigh, she just sat there.


On the Deck:

Airbourne, didnt get the sunset as I'd hoped :(

Landed, on the garden table :D
 
Here you go Pazza:

Based on the fact this CF is really weak I've already decided I will do something along the top. Torn on what to do with the arms though, but think once I'm happy with the basic shape I'll certainly buy some wood if I can't get the CF or not got any Alu by this point just so I can build something that flies again. It's been too long!

Looking good,you can allways get some 12mm x 12mm wood from wickes,i think B&Q do it as well.
 
Someone was flying a phantom at devil's dyke yesterday - not clever considering how busy it was. No one flying HG or PG at the time but there were a few unhappy utterances ...

Anyone flying the HK FPV250 frame? Tempted to build an FPV racing mini quad as the ground station is nearly finished


The right setup can fairly shift for something so small

Finally got a box for my Vision, and spent what seems like hours plucking it.

Im a bit paranoid the case will bend the props, but I dont want to keep removing them. Ill just see how it goes.
