Some other neat videos on this link as well.

I still dont understand how they claim 40+ min. flight times.

japp 40 mins hmm and 140 per hour. These resellers dealers have to start sharing their secrets

 

[BorisS]

But it must be a misunderstanding because the same guy in hover managed with no payload 20 mins

We used our new 16inch paddle props and 340kv brushless motors. So far so good, some small changes are still needed with this setup.
We managed 20 minute flight time using 10,000mah 5cell batteries and NO payload.

Yeah, seriously, this has to be a mistake or a serious outright lie to gain interest.

Regarding that XP2 quad, although I work for a laser cutting, sheet metal fabrication company and I have spent countless hours trying to figure out a design utilising the tools and aluminium sheet at my disposal, I eventually realised there is no ways to make a frame as strong or as light as simply using some G10 and some aluminium extrusion for the arms... 450g is too heavy for that size of quadcopter, different materials can yield such better results.

Here is the frame I laser cut, also weighing in at around 450grams. It works, but I have ordered a sheet of G10 and will replace the aluminium components (Everything but the amrs lol).

Orracle, I like your design, very neat! The first one on this post isn't bad, but a bit ugly for my liking!

I also like it a lot ! I just don't understand the handles that are going up from the landing gear legs. Wouldn't they be in the way of the props or at least reduce the efficiency of the props trust ? The less in the way of the props thrust the better concerning efficiency and vibrations was up to now my believe.

450g just to much for that size, isn it?
you can do same frame out of four alu square booms and some gf, weigh will be 150-200g, so you have about 200-250g "free" - thats weight of any modern p&s cam with 1080 video.

save your money and thus increase you flight times guys)

cheers

Hi Boris

I designed them like that, because I realised that as a beginner I would probably crash a lot (which was true) so I wanted to try and protect the motors, being in South Africa getting spares can take a while. I know most of newbie crashes are flips landing upside down which can generally bend a shaft, but that is easy to replace. But these legs have saved my motors in the few cases I have managed to ummm... cartwheel my quad end over end lol.

Below is picture of the quad showing the clearance between the legs and the props. And below that some of the damage I have done learning to fly, the one on the right was redesigned to be stronger.
