First of all you don't need an engineering degree, you just need to be able to read and follow instructions. Years ago it was hard to get into this, as you would have to do alot of programming for the brain board etc. Now you can do it from your Android phone via Bluetooth, it's that easy.
To be honest, these are a lot of fun without FPV'ing them. FPV'ing them makes them easier to fly, by far. A good FPV setup on a multicopter will set you back if you have no idea what your doing. For instance, you can buy a patch antenna to receive video signal or you can make your own (which is much more effective budget wise and signal strength wise)
FPV planes will be a lot cheaper and easier, as you have more space to put the equipment on, squishing up equipment causes interference and unless you know what your doing will cause you to crash. One of my more funniest FPV planes is less then a hundred dollars and can easily get round a large field but is more for stunts.
Swe is in the same boat as you, not knowing much about it and taking it step by step. Following him (if he keeps us updated rectangularly) you can see how he does it and what problems he has to overcome.
I'm reading trough these two threads, because they got some quite good information. Although it can be hard to read since the OP seems to hate capital letters.
I'm currently looking at this motor. It's quite cheap and seems to suit what I'm building.
It operates between 4A-12A and peaks at 15A. Someone did a benchmark and it did between 620g - 900g thrust depending on the propeller. So an electronic speed controller that has a max current of 15A and can do 18A burst seems suitable.
I have no idea what this programming ESC deal is about, so the ESC I'm getting is limited. Sad thing is that there are none in stock at the moment :( I may just pick something else instead.
So, between 2480g and 3600g max thrust from all the four motors depending on propeller. That sounds awfully lot. May have to recheck. Anyhow, according to that post if I divide it by two I will get the amount of weight that the quadcopter has to be below to lift at 50% throttle.
So 1240g and 1800g. Obviously my quadcopter is going to get below 1240g.
By that logic I could get a liftoff at 25% throttle if my chopper is just below 620g. That's neat.
Best thread ever. Has practically everything.
Already ay $91 not including shipping.
Je hebt geluk dat er geen mocros op het strand waren.
Anyways, nice video :)
and get this programming card -> http://www.rctimer.com/index.php?gOo...8&productname=
Because you need to change the cut-off settings on the ESC so you dont get one shut off in-flight, really easy to program with this card.
Shipping from RCtimer is fast and cheap.
These are my favourite motors which in my opinion are by far the best
Ah thanks a lot!
The motors you originally wanted to get are fine, ESC's are not though.
My top two multi copters (my quad and my tri) are running those motors and those speed controllers. Both are flawless.
If you need any more help, let me know!
I wanted to get into FPV since the other thread about it but it seemed REALLY expensive to me (with fixed winged craft) since I am not willing to build a frame from foam (for a plane). And I live in a city / nearish to an airport / would really just like someone to have made a parts list for me. Maybe in a few years when I have a paying job and am done with school. :(
I could really do with a list of parts I need to buy, I'm rubbish at all this research.
I've also been looking through Hobby King. RC stuff is one of those things I'd like to get into once I have some money to throw around.
I had no idea there were such important features in the ESC's, thought an voltage alarm was enough
As most of the people here in this thread I find this really awesome and want to get in it, but I have no knowledge of anything about it really.
I did some reading though and I'll try and make a parts list and post that here. It will be based on one of those pre-made frames, since I can't really make anything myself.
The more I think about this the more excited I get
I must tell you guys one thing. If you're ordering a lot of stuff check with your mail office if they add VAT.
Just got a letter from my mail office that demands me to fork out $30 due to a things I ordered online.
I modelled this in Inventor few weeks ago to seve as centerplate for our multicopter. It will have diameter of 18 centimeters and will be cut out of probably 3mm thick glass fibre plate. Two of these will hold the whole thing together, mainly the carbon composite prisms for arms.
Also you can tell them to put the value of the package as something it's not.
Anything under eighteen dollars will not get import duty ;) Also if the item is classed as a gift, it will not get import duty.
Hey Swebonny, very interested in the Multicopter you are building. I was wondering if you could make a new post that has the list of everything in your project currently?
This is still a good thread. Swebo, spill the beans: how goes the multicopter?
Here's what I got:
A voltage detector.
And some glue. I want to add some more glue to the frame.
Here's another picture:
As you see I'm doing it really slow. But once I get my wage, I'm probably going to order everything in one go.
The control board.
The propellers, I'm most likely going to order a bigger ones as these below are quite small.
Voltage detector, not really a must.
The motors. 4 of them.
And normal cyanoacrylate glue, aka superglue. You can get it pretty much everywhere.
So yeah in the end you're (not you specifically just anyone getting into the hobby) still in this over $100 after the remote. Seems about the same price as planes, the FPV stuff is where it starts getting really really expensive though...
Yeah, I'm way over $100 if shipping or other fees are going to be included.
are you a alien???
The FPV costs and the cost of a good controller are what make me uneasy. I'd love to give this a try, but I'm a broke-ass college student! I could reasonably afford two or three hundred bucks, but beyond that, I'd be dipping too far into my "uh oh" money.
The only part of the FPV side of things that is expensive is the video display. I tend to use video goggles which do cost quite a lot but again, you can snap some up on eBay really cheap. (I will post some of the ones I have in my next post)
Swe, don't be worried about going to slow. The slower the better, you will end up with a much better Quad at the end of it. Keep us updated!
I've been looking up how to connect the ESC and the motor and other stuff. This video is really good.
Absolutely awesome Multicopter video, in the Everglades of Florida.
(Note, Alligators (or crocodiles?) included in video. A.K.A. Extra awesomesauce)
I've always wanted to build one of these, but using my power source of choice would mean a rather complicated transmission is required. Either that, or several tiny little Cox engines with throttles.
How easy are they to fly?
This thread makes me want a realistic RC V-22 Osprey.
Wait why the fuck was there a tiger
First actual physical work done on our quadrocopter.
Fibreglass and carbon, bitch.
It weights about 220grams, from tip of one arm to tip of the opposite, it's approximately about 50cm.
At least the MikroKopter control board changes the throttle on the electrical engine several times during SINGLE TURN of the propeller. You simply cannot get precise enough throttle management on a combustion engine.
Combustion engines would become feasible at much much bigger designs, where the slow reaction would be sufficient to stabilize the heavier, clumsier craft, but there's no chance you would get it working at these small scales.
If you have a boner for combustion engines, interesting idea I am pondering about for some time would be using normal electric engines for propulsion, and single bigger combustion engine with a generator, which would recharge the battery. That should be doable, and would be rather cool.
I wanted to build one, then I went to the site you linked and the controller board is £75.00 alone, not to mention the motors, controllers and everything else.
Even if I bought the barebones PCB, I could never find a store that sells all the specialized parts like gyros & whatnot.
And I don't have a hot air soldering station, which is kinda necessary for SMD parts
KKmulticopter thing seems to be the way to go.
I have zero experience with it, but I am probably going to try this $30 thing of theirs , after finishing this one.
