Multirotor, multicopter and quadcopter discussion - The Drone thread

Picked up the Tricopter today, man I have some reading to do :D

Got the gopro2 with 2 spare battery and charger for basically £20 as he didn't have the fatshark camera and used the gopro for fpv so knocked some cash off. Just hope the weather holds out so I can fly it!

Pics!
 
Whos a free and easy host to upload some from a phone? Only just figured out the charger so time to move onto the radio, turnigy 9x any thing I should do to it or advice?
 
Postimage.org works from my Windows Phone 8. Don't have a 9x myself but a few here do. I imagine its already bound (paired) to the receiver (Rx). There really isn't much to do to make it fly tbh. Id take the props off and test the channels are set correctly by giving it some throttle and testing all directions. Make sure the trims are centered before your first test flight, or rather hop. Don't run before you can walk ;)

Tris sometimes need a bit of rudder trim to stop them yawing on their own, depending on the prop and tail assembly setup
 
The Turnigy 9x needs pairing with the receiver when new.

Rebuilding my quad again today. PVC pipe frame! Half way there, just need to sort out the motor mounts and attach everything :) Pics later!
 
Well I had a fly about and it's a monster, took it easy and it feels a lot nicer than the hubsan I have. Fpv is really weird and worrying when you can see yourself a fair bit off but it sounds like it's on top of you but I'm sure i will get used to it....need a holiday now so I can spend some serious time flying :D
 
Quick picture of the rebuild:

-H shaped frame made from 21.5mm PVC pipe.
-Battery sits protected from impacts on the inside (there are GF plates on top and below take from my old HobbyKing frames)
-Bolted together with M3 bolts. Frame isn't glued at all, the individual motor mount sections are held in with bolts so I can easily swap them over when (if?) they break on a crash.

I could do with the motor arms being a little longer, the props overlap more of the body than I'd have liked and the clearance to the receiver in particular isn't big at all. So far I've only tested a hover but it seems ok. Will try a proper flight tomorrow if I get a gap in the weather.

Looks awesome, do you happen to have a rough BOM for this?

Assuming you want info on the frame - it's maybe a metre of PVC pipe, and 4 T connectors. The pipe is about £1 a metre in B&Q and you can get the Ts there too, looks like they're about £1.50 each though :eek:
I just had the stuff lying around in the house, although going forward I'll likely get more pipe. I can't see the Ts ever breaking though!

On top of the PVC, there is 8 3cm bolts along with a handful of nuts to hold things together. To make the motor mounts I just boiled some water and stuck the ends of the plastic in, it makes it soft enough to form - once soft just jam between 2 blocks of wood to flatten it out.
The top and bottom plates are from another quad frame, but you could make something similar with a cut sheet of glass fibre. The bottom one isn't really vital, I just had it lying around to make things stronger and protect the battery.

If you want a more detailed explanation and a list of all the quadrotor components let me know. Although I'd not recommend going this scale now, the smaller 250 builds with smaller props look to be the in thing now :D
 
Looks good PinkFloyd, I agree that the arms look a tad short for the prop setup though. The pipes look a clever way to cram a lot on a lightweight mid sized frame for buttons :)

Yet another weekend where it's been too wet/windy to do any flying :( I can feel the season drawing to an end already :mad: Time to investigate some abandoned buildings/factories when the rain draws in! Trespassing? **** yeah :D
 
I've been toying with the idea of building a frame from wood, but those pipes look like a great way to make a home built H frame.
 
I sometimes use a bit of stripped wire as a solder wick, essentially the same thing as desolder braid you buy. Works best with high quality multistrand copper cable.

Wood is also good, might try it for my next build. Seen many people using balsa and plywood for a arms+body combo, also builds where a single sheet of plywood is cut for the whole frame. Pipes definitely seem good though, flew it earlier in a break in the rain. Flies really well, nice and smooth in the air :)
