Arcturas posted:The receiver plugs directly into the flight control board almost all the time. I barely know anything about quads (only what I read, no hands-on). Can you clarify "One of the ESC connections needs to have power"? I thought ESCs had battery and flight controller in one side, motor out the other.

I assume he means one of the servo leads from the esc needs to have the red positive connection attached so the 5v out BEC gives power to the flight controller.JawnV6 posted:Is there a concise resource for getting into quadcopters? At least sorting out the terminology and options for various subsystems?  Here is a simple wiring diagram to give you an idea of how a fpv quad is wired. The only invisible magic not shown is that the pads where the arms attach are actually all connected to the battery as a lot of quads use a printed circuit board for a lower frame. The flight controller is the Motherboard and your power distribution board/frame is your power supply. Each ESC must be connected for power to the power supply, and each esc also must connect to the flight controller which sends it throttle signals. Most ESCs also have a regulated BEC which outputs 5v via the servo connector. This is more important in planes where it would power your receiver directly. Your receiver is abstracted from direct control of the ESCs and connected to the flight controller either by individual cables to each channel(elevator, throttle, etc) or using a single cable that carries a signal with all channels(ppm, sbus). The flight controller will power the reciever. Other than that the only hiccup is some flight controllers are not able to be powered by the ESC's BEC and have separate voltage monitors/controllers which handle powering the unit as well as work as a battery level sensor. For those controllers it is recommended to remove the red power wire from your esc servo leads. tehk fucked around with this message at 23:21 on May 1, 2014 |

I got my mini Y6 built and flying around. It's a bit too underpowered to carry the Mobius gimbal right now, but I think with some weight reduction it's possible. It flies great with the Mobius and a 2200mah 3S, though. AUW is 575g Using Suppo A1510 2200kv motors with 6 amp ESCs and 400mw 5.8ghz with a PZ0420 camera. Naze32 FC and Rangelink UHF.

My FPV camera and other gear came in  just waiting for the actual plane, etc. Tested the gear and it seems A-OK.I'm considering ImmersionRC's EzOSD to add on to things because I love the feature set and seems genuinely useful. Can anyone fill me in on the difference between the "plain" ImmersionRC EzOSD (http://www.multirotorheli.ca/products/ezosd-on-screen-display) vs the "Team Black Sheep" version (http://www.profotouav.com/product/tbs-immersion-ezosd/)? Other than like $60 more  I don't really get what's different (other than one of them can't be found in stock for neither love nor money at the moment.)

What's the reason you have up and down props on all three arms? Just getting more power on each arm in a smaller footprint?

Arcturas posted:What's the reason you have up and down props on all three arms? Just getting more power on each arm in a smaller footprint? It's a Y6 hexacopter, so the orange props spin one direction and the black props spin the opposite. The copter yaws by spinning the orange ones faster or slower than the black ones, which "twists" the copter from the torque generated. It can also offer some redundancy in case a motor or prop fails, but the flight controller has to be able to compensate for the failed motor.

Yeah the general idea is to have the power of 6 motors on a frame that's the size of a tricopter. They are slightly less efficient when stacked though. https://www.youtube.com/watch?v=0Y6JtgN1kZA

I had my first good proper fpv flights with the qav250 yesterday. I'm still getting used to it but it is so much fun. Much more fun to fly than my bigger quad. I'm getting a bit of jello on the mobius so I need to do a pass balancing props etc and add a bit more foam on the camera mount. https://www.youtube.com/watch?v=cd96ZWsYqO4

That x8 with the split arm booms is pretty dumb. Wonder why they just didn't just mount the second motors upside down on the same arm and save a ton of weight. This mini quad craze has me tempted. Is there a reliably restocked source for either the Tiger MN1806 2300kv or the Sunnysky X2204 2300kv? Are they the only worthy 3s options? Frame wise is the blackout actually worth it or is it just bandwagoning? Better options?

Those motors are in a worldwide supply shortage. I'm running my 250 on cobra 2204 1960kv motors on 4s. The extra power is nice for pulling out of a hard dive quickly. Flight times are good at arrond 8 mins of mixed flying using 1300mah 4s packs. Punch out at full throttle is pretty

Nice. Thats a lot of  to go to the trouble of making that  I had my 250 out in a pretty strong wind yesterday. I still need to balance my motors and prop adaptors to get rid of my mobius jello but it was a good time. The mini handled the wind so much better than I was expecting. I didn't even bother flying my Caipirinha as it was too strong to have fun with it. https://www.youtube.com/watch?v=pv1fW3OEvng Warning loud motor noise. Best to mute. Unless you like the sound of angry hornets.

Thanks yeah it was a lot of talking but I'm just getting so tired of reading everywhere about a 400ft FAA law or this or that, even magazines and newspapers don't do any research past calling the FAA's local office and asking the receptionist it seems. I thought I posted this earlier but didn't post it here, but the annual Colorado FPV meet is coming up soon, here are the details! Hello all Colorado and nearby FPVers! The time has come again for another FPV meetup and campout in South Park, CO. Every year has been a great turnout of FPVers and a great time. We have a great location picked out on BLM land away from everything where we can fly all we want over wide open spaces. We have woggle courses and races and contests as well as just hanging out by the campfire. Location: 38.921331, -105.761771 See our main meetup thread on FPVLab here: http://fpvlab.com/forums/showthread.php?25680-2014-4th-Annual-Colorado-Spring-FPV-Meet...-June-6th-8th quote:Bring your planes, bring a crash kit, bring your camping gear, and bring some meat to cook on a stick over the camp fire (don't forget your favorite beverage to enjoy too). It is time for 4th annual Colorado Spring FPV Meet.

It seems like everything decent miniquad wise is out of stock everywhere. I am keen on either a v2 qav250 carbon/plastic, or the blackout and they seem to be impossible to find like the popular motors. I tried ordering from two Lumenier distributors only to find out they actually dont have any on hand but forgot to mention it on their site. Giving getfpv or readymade a week to get poo poo in stock or I guess I will take a pass until my Vector flight controller proves to be more than vaporware I paid $200 for.

Are there any miniquad frames that have prop covers/prop guards? I'd really like a frame kinda like the Parrot, but half the length/width, that I could build with. I'd like the guards partly to save on prop replacement, but mostly so I can feel safer around the thing.

If you want a miniquad you better get used to breaking props. The 5x3s will break during normal flight.

Yeah, 2.4 ghz and spektrum were not a thing in 2000. Now, Hobbytown does not sell 75 Mhz hardware anymore. I was excited things are easier now, but figuring out what hardware I could salvage was annoying. To add to that, I can now buy a homebrew 2.4 ghz DSMX module and plug it into my Hitec Prism and make it do the modern bind and fly dance for $100

After impulse buying a Syma X1 and enjoying the hell out of it for the last month or so, I decided to build a larger quad. This is what I came up with: It's based on this hobbyking build. A 330mm frame, HobbyKing KK controller (sadly not the KK2), with 8x4 inch props and 1200KV motors (on a 3s battery). I'm hoping to eventually have a setup with a more fancy GPS enabled flight controller on it, probably a Pixhawk, but wanted something to get me in the air right away before I sink $$$ into control boards. It had it's maiden flight today, and to be honest it scared the crap out of me; it's REALLY fast/aggressive in flight, I could only just control it (as evidenced by the scratched up propellers). I'm going to try dialing down the sensitivity on the transmitter handset sticks (there's a "dual rate" feature that will let me set the range of the sticks), is that the recommended way of taming an overly aggressive quad?

So I have a E-flite Apprentice and bought a charger, but the cables don't match up, and I can't find any information on what the hell I need to get to actually charge this thing (the charger it comes with is DC only, and I didn't want to buy a power supply or use a car battery). Anyone have information on what I need to get? I'm sure it's obvious if you already know what you are looking for, but for whatever reason it is hard to find information on all the different connection types. I also ordered a couple of 2S 180mAh batteries from E-flite, what other thing will I need to charge those? I'm sure it won't just be plugging it in and being happy. subx fucked around with this message at 05:17 on May 29, 2014 |

If/when you break the arms on that 330mm frame, you can just get the 450mm frame since that motor/prop combo can easily lift way more than you can squeeze onto a 330 frame. Also you can tame down the lift/fall balance a bit by adding more weight if you're having trouble hovering at 50% throttle or descending. Though try setting your radio's dual rates first of course.

Depends on the charger, but most can use a decent range of DC input. As for the cables you need, take pictures of the connectors

I fired up the Live Chat on the Hobby King website and it went fine. The chat responder connected me with a product specialist who confirmed the wings in my kit were faulty based on my photos. They waited in the chat while I filled out the online RMA form, then processed the RMA, confirmed replacements were available and connected me to a customer service rep who finalized an order for replacements to fulfill the RMA. Lots of waiting in between chat updates, so almost an hour and a half from start to finish but it all went fine. I'm disappointed I'll have more waiting before I can fly, but that's life. Unless I find some way to MAKE these fit in the meantime. (It's styrofoam like a cheap picnic cooler, so I don't think boiling water or heat gun will work, but I might as well try something.)
