Multirotor, multicopter and quadcopter discussion - The Drone thread

It looks like I have a dead speed controller or motor. I tried to take it off but one was spinning not as fast as the others so it flipped right over and broke one prop. It's great how little damage was done :D. They are all brand new, would be surprising if it was DOA.
Ahh I think I need to calibrate the speed controllers, doh! I have forgot about that.

What does calibrating the speed controllers entail?

Just turning the throttle on the transmitter to 100% while plugged into the receiver and then put it back to 0%. Fairly easy.
Here is a picture of the completed build. Going to tie it down in the garage tomorrow, to see if it flies okay without damaging it all.

Zomg it actually properly flies yaw is fixed now with a bit of left yaw trim. Don't know why it needs so much though. Hey ho, it sounds alright when flying and is controllable. Might enable auto leveling next :D.
 
Awesom, I,might get a new frame that is stronger and lighter, still has an awful amount of power though with just a ratio of 1:3. Goodluck buy has some cheap fibreglass stuff. If it does break it will be harder to repair than my wooden frame though.
Had two flights last night, my god it is easy to control.

Is it possible to make smaller cheaper versions of these?

Yes. You need smaller battery, low ampage speed controllers.
I am beginning to get basic control, keep tracking of orientation is damn difficult though. I am getting used to fly in gyro mode, level mode takes away a lot of the difficulty but you need to get the PIDs right first.
Ordered a bluetooth module for a tenner, going to be quite helpful. Also Easter holidays are soon, which means I can ram in a dozen flights a day.
 
I just use rcgroups, just get stuff off giantcod instead of hobbyking if you can.
I am really annoyed with European law about fpv, it means that 99.999% of all FPV pilots have to break the law. Why? because we are limited to a measly 25mw.
Where can we get 25mw equipment? The only company in the world is immersion RC and it is incredibly overpriced. It's just not worth the hassle and in all honesty it does not do any harm and ofcom don't have the equipment to tell between 10mw and 100mw.
I would say that a large %age of households already break the law with the use of wifi boosters which are sometimes around 1w and I have never heard of anyone care about that.
/Rant

I would say that if you are in the UK and are about to do FPV ( just like me), you will probably have to break the law but why would ofcom care if you are flying in a open field away from civilization on 5.8/2.4 ghz band which are just a "dump band" where anything goes.

Just seen that this has finally been bumped :).
You will have to learn to solder as you need an awful lot of bullet connectors. I think I can count 20 lol.

Wish I had the ability to make this! Looks pretty good!

You do :)

I'm currently building a tri, frame is complete and ordered some components. I'm worried after reading about the care needed over Lipo batteries about keeping it in good condition. What (if any) Lipo alarm are people using/can recommend?

Check to see if your flight controller has it, you just need a potential divider circuit and a buzzer.

Hi guys, I fly RC planes for last 10 years or so now. I am interested in this FPV though.

Is it expensive. Light etc? Let me have some details of cost and what is needed, could be interested in getting this into one of my models.

Could be a lot of fun and another area of RC i have yet to explore.


Thank you

You can get kids on fpv hobby for about £70. And with low gain antennas ( preferably Cloverleaf and Skew-Planar) you can get about 1-3km depending on your location.
Aside from the kits they sell, you will need a small TV, a BEC on the plane to power the camera + transmitter and a BEC on the ground station to power the video receiver.
Where do you live? There is an annual FPV meeting next weekend around the oxfordshire area, you need to be quick to sign up. Head to the UK FPV thread on rc groups for more information.

Just got back from a UK fpv meeting oh my god it was pretty much a multi rotor fest.
Naza's, massive huge DJI stuff, a few multi wii gear. Videos will follow shortly, let's just say that buzzing things was fairly common :p.
I also nearly got hit by a spider as I stood up and walked away, then 1 minute later it crashed where I was sitting.

Never tried a simulator but I heard they do help, haven't had any bad crashes but had a few tumbles and that was because I was flying 20 ft away with no way of keeping orientation.
I would for a quad-spider frame design, as if you go down the fpv route in the future then you have much more room in the center for electronics. I still think that wood is one of the best choices as it dampens vibrations and is easy to fix in any crashes.
Power distribution boards take up a bit of room, y harness is better in my opinion.
What flight controller are you going to use?
