Multirotor, multicopter and quadcopter discussion - The Drone thread

[RomanNose]

Can you link me to a frame that you'd recommend? At the end of the day I'm happy to swap out the frame at a later date once I've got the hang of simply flying the thing!

I quite like this frame

But you could design your own wooden frame spider frame. Aluminium is a decent material though anyway, easy to find replaceable parts.

Oh yes I have to show you my new IMU,

It's the GY_80 can be found on ebay for ~ £20. 10dof .
I haven't tried Baro hold and mag hold yet, but it will be interesting to see how it goes.
I hope to see some videos wonder, that new HK board seems quite interesting.

 

[RomanNose]

What the hell is an IMU? I thought I was getting the hang of this terminology!

It's just loads of sensors integrated into one board.

 

[RomanNose]

What does IMU stand for?

Also you've got the CF-2822 motors, do you slacken off the hex screws to mount the base and then re-attach?

Yeah I think you need to because you can't get the screws through without mounting the base first then attaching the top half.
You might want to see this wiki page.

[RomanNose]

Did you loctite them?

Nope.

 

[RomanNose]

Any issue if I do? I'm going to loctite the screws that attach the motor to the frame so any reason not to do those ones?

No reason why you shouldn't, if you do change motors you can just get some that fit that motor mount.

 

[RomanNose]

It is possible but only with level & altitude hold.
Well perhaps you could fly with just altitude hold but it will be really hard in acro mode.
Warthox once flew two quadcopters at the same time, while one was locked in with position,altitude & level hold.

How many x4s we have now in this thread ?.... Maybe sometime a multi rotor meet at some scenic location for good filming

There is a UK FPVr meeting each year that has a lot of multirotors, went to it a few years ago.

I will be there next year hopefully.

 

[RomanNose]

Can you recommend a better Flight Controller please? My budget was £150 but I'm really liking the look of this

3DR Pixhawk looks really nice when it comes out.

 

[RomanNose]

Fpv gear I use security cam 2000
Hobbyking has a uk warehouse, check that out.
Use giantshark for bits and bobs + batteries.

 

[RomanNose]

Doesnt give me any options to use the UK warehouse annoyingly. Dont fancy driving there either as its abit far.

Some products are not in the UK warehouse, the website is so fiddly. Needs a complete redesign imo.

What's a good radio for a F550?

I've seen a Futaba 8FG Super mentioned several times, across various forums... but I can't find anywhere with stock.

9xr is a very good transmitter for its price.

 

[RomanNose]

Spent all night hunting for various bits and pieces in the UK, it's bad enough trying to find things actually for sale in Europe! Think I'm going to have to give in and order the radio/receiver from the global section of hobby king and accept it's going to take donkey's years to get here Time to learn how import duty and stuff works I guess?!

On the quad side of things. I've been chucking my Hubsan around like a loony and whilst it charges just sitting and watch acrobatic videos all day, I've changed my mind. Going to go with a smaller quad (12" or so), 20A blueseries esc, ~1200kv motors and 8045 props I reckon. Think I can just about get everything for the quad from the UK store providing I accept that I'll need to be doing some soldering!

Seen some damn nice custom quads browsing RC Groups, Love this custom frame!

It doesn't take that long tbh.
Regular air mail has taken 1.5 weeks max for me.
And there is the new hobbyking shipping method ( option called channel shipping) which takes about 3-10 days, very fast. Usually just £2 extra on the order.
HK post is bad though, singapore mail is pretty good though. If you use channel shipping it will avoid the very long shipping times of the dreaded HK slowboats.

Care if you fpv today, just been up.
The cloud base is insanely low. Where I was, it was about 200 ft from ground level.
I was actually in the cloud at one point.

 

[RomanNose]

My most recent one I have been working on.

Runs on 4s 2200mah, 35% hover.

1.1KG auw on 4s.
I think it's a bit heavy, I may change the plates to g10.

 

[RomanNose]

I use 14 awg/16 awg. Turnigy silicone wire. Which is really nice quality.
I use a power distribution board, then an xt60 connector onto the battery.
It's so much cleaner than making a y- connector up. Also can easily add LEDs etc.

Use moongel for dampening on the fc, it's worth its weight in gold.

4s 1000mAh bolts coming in tomorrow for some liHv fun. Camera will be a yi or gopro depending on the style of flying I pick.

 

[RomanNose]

You're way way over propped for those motors on 4s. Plus, those 1000mah packs will be dead in no time, assuming the escs survive.

Possibly yes, I normally buy a bunch of props and figure out in the maiden which to use by checking motor & esc temperatures.
