I bought an FPV setup last night for a quad that I dont even have in my hands yet. This is my first FPV setup, so I'm still unclear on the details. Here is what I got: Quanum FPV Goggles (Super nerdy, but also super cheap): http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=53706 Boscam 5.8G 200mw TX: http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=18972 Boscam 5.8G RX: http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=18649 Gopro AV-Out cable (so I can record and do FPV with my OG Gopro): http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=46369 For a setup like that, running on a quad with a 2200mah 3S battery, should I be running a separate battery to power the TX? Is it safe to run it off the main battery?

The gopro will also be running on its own internal battery, so it won't even factor into the drain on the main battery

I have a gopro 1 (HD), so I dont even know if thats an option for me. In the beginning I'll be flying FPV really close range to get used to it, so if my FPV setup goes wonky I can fly it back line-of-sight. So by the time I'm ready to venture out further/higher, I should have a good idea of what the battery life looks like on the gopro

I've never flown a Bixler, but I've flown planes very much like it, and it either sounds like your prop is on backwards (triple check this), or you have some fundamental airframe issue, like two left wings (one flipped over) or something goofy like that, OR a power issue, like you're running a 2S battery when you should be running 3S.

Generally, the side of the prop with the size/brand/etc stamped on it is the "front". So on the bixler, the writing should be facing the motor. On a non-pusher plane, the writing would face away from the motor.

Are you really interested in the scale looks that the beaver has? If not there are many better beginner planes, but many aren't as scale as that. Don't go nitro/gas unless you specifically want to run a piston engine for some reason. They bring a whole other world of problems and oddities. Electric is 100x easier especially for a beginner.

Just finished up the build of my HK Q450 quad. It was a decently easy build over a couple nights. Already really loving the KK board for its simplicity. Also already can tell that I'll need to replace the bottom of the barrel HK motors I ordered with something better, you can just feel that the bearings are not that great. Also the HK props are not perfectly balanceable because the hubs are drilled off-center slightly  Either way, for now its good. Had the first "can this thing get off the ground" maiden in my garage tonight. The answer is "yes, when the motors are hooked up in the right order", which they werent at first. Looking forward to maidening it for real this weekend.

Did a real maiden today. Maidened it with auto level on. That was a mistake. It was drifting like crazy and I had to fight to get it anywhere. I turned the auto level off and it flew much better. I'll see if I can calibrate it some more, because I do see auto level being useful. It yaws pretty slow and tends to overshoot the yaw. Any recommendations for adjusting that out?

mashed_penguin posted:You should replace those props asap. The vibrations will make the flight controller perform no where near as well as it would if they are smooth. Good luck with the maiden. Uh you werent kidding. I stopped by the LHS after work today and picked up a set of APC Multicopter props in 10x4.5 They were all really really close to being perfectly balanced out of the box, but I taped them anyway because the  in me could not let them go slightly unbalanced. I tried a hover with them on and its like a different quad already, much more stable and a ton quieter.The only thing I dont like is APC feels the need to file their props to a razors edge before they leave the factory. I never understood that, even when I flew APC props on my planes I felt like I had to be extra careful around them because they were so sharp.

I had the ultimate RC nerd life event tonight. Yesterday I crashed my quadcopter. Bad battery, at the end of its life, quit unexpectedly and the quad basically fell out of the air. I was flying fpv so I got to play "find the quad in the tall grass without seeing it go down". I found it with a broken arm, broken prop, but otherwise ok, just dirty. Tonight, I decided to dig my Beast biplane out, and see if she still flew. She did, but pulled hard to the right. I was trying to fly around the pull and bring it down, but wound up on the roof next door. The house is a very tall 2 story with a high roof line. I dont have a ladder high enough to get to the roofline, and no one lives in the house right now, so I was stuck. So I did what I could, I hauled the quad out, zip tied the broken arm up, stuck just barely 500mah of charge in the remaining good battery because it was rapidly becoming night time, tied a weight to a string and tied the string to the quad. Up she went with a broken arm, next to no battery and at least one bent prop in basically twilight. I took a shot at snagging the beast with the weight and missed. The weight was swinging wildly and pulling the quad around a bit. I had one more shot and basically no battery, so I went for it. I went back up, essentially threw the quad at the plane, drug the weight and string up the roof and managed to snag the tail wheel and elevator of the plane. I gave it a ton of throttle, lifted the plane up, and essentially slowly fell back out of the air with the plane attached to the string as the battery died. One last full throttle goose about 10 feet off the deck to keep the plane and quad from smacking into the driveway and both were back safely. Holy poo poo I can't believe I pulled it off!!

Blade 180QX is also a great starter, better for outdoors, but can be flown indoors as well. I have a Blade MQX, which is the same copter, just the older version and I have a ton of hours on it. Still kicking, still flies great.

MrYenko posted:I've been pondering a quad for quite some time now, but I have zero R/C construction experience, and no extraneous gear. (Most of the scratch or kit quads seem to be low priced because the builder "just happens to have" the motors/batteries/transmitter/etc, already, and I don't have that luxury.) I've been flying my S107 and Blade Nano for about a year now, and it's time to move on. I have a 450mm hobbyking sk450 based quad i can sell you. You'd need to add a receiver and replace the broken arm, but other than that it's rtf

Yeah, until this it had never been apart, was sitting on his dresser for the last couple months since he got a new iphone. Came home the other day and the battery had puffed and completely delaminated the phone. He got really lucky the battery didn't puncture and start a fire, considering the incredible pressure it must have been under to split the phone like that and all the pointy and sharp pieces inside an iphone

MrYenko posted:Flew my quad for the first time today, after a long string of delays. Even with the factory default flight controller stabilization settings, it was reasonably stable, and the only thing that kept me from continuing for more than a few minutes was the fading light. Glad to hear you got her up and running and that it's working well for you. I only ever used the Velcro strap and it never let go on me. I used a pretty beefy one though so that might help

How long had you been in attitude stabilization mode? The gyro for that drifts and is not perfect. I never used it for extended attitude holding, just to correct attitude momentarily if the quad got out of whack. As far as I know, that's what it's for, "oh poo poo" moments where you need the computer to save you, basically. If you balance your motors and props super accurately it will hold attitude for longer, but it will never just hold it endlessly. Also, it's understanding of "level" is dependent on how flat of a surface it's on during calibration. Someone more familiar with the kk guts can correct me if I'm wrong, but that's how I understand it.

As a known Slow Stick aficionado, I have owned many gws slow sticks. I learned to fly on one, put my first gopro up in the air on one and was doing ap on one way back in the early 2000's. My main gripe with them has always been the super scalloped, undercamber wing that made for great lift at low speeds, but made it impossible to fly in any wind or at any reasonable speed. It was also made of very brittle foam that would crack easily. Lo and behold, hobbyking has remade the slow stick with a normal epo wing and ailerons!!! http://www.hobbyking.com/hobbyking/store/__39818__Hobbyking_Slow_Stick_Brushless_Powered_Airplane_EPO_Carbon_Fiber_1160mm_ARF_.html I guess I'm getting back into the slow stick game!!

Yeah, he was pretty clearly directly in line with the sun, made worse by it glaring off the ocean. The plane was probably an un-orientable black blob at that point.

Built a Flite Test Blunt Nose Versa over the winter: http://flitetest.com/articles/blunt-nose-conversion-ft-versa-build It was my first scratch build and went pretty well. So far the wing has been a pleasure to fly. Its stable and rock solid in calm weather, and manageable when the wind picks up. Tough too, I had the prop saver come loose today, effectively killing power just after launch, and it smacked a bush and cartwheeled along the ground. No damage, pretty happy about that. Here it is flying in next to no wind (a rarity around here) and getting up above the fog coming off lake michigan: https://www.youtube.com/watch?v=9XtazoH_K5Q

I work at an electronics recycling company and someone recently recycled a Parrot Bebop 2, battery and charger. So rather than send it to the shredder to get melted down for precious metals, I’m gonna try to get it back in the air. The battery is extremely swollen and the light on the charger does not come on when I attempt to charge it. I’m assuming the battery is shot, so I bought one of these on amazon: https://www.amazon.com/dp/B07ZMR96ZN because it was the cheapest way to find out if the battery is really dead (more likely) or if the drone and charger are both dead (less likely but still possible). The drone has a micro USB port on the back. Is there any way to power the electronics off this to see if the drone works at all? If the drone works I’ll probably invest in some more batteries and maybe the physical controller. I really hope I can get it going because there is no way I’d spend the coin for something this advanced myself!

I’m just impatient and the snowstorms in the Midwest mean the battery was supposed to be here yesterday but isn’t yet. And I’m impatient. I’ve since done more research and the micro USB port is only for firmware updates and stuff with the battery already connected for power.

For those of you who fly/have flown Wifi drones like the Bebop 2, I have to guess its worth investing in the physical controller with the big fuckoff antenna on it? Granted, I have about 30 seconds of experience with my Bebop 2, but just given what I know about wifi and its congestion near me, I'm not hopeful. The drone has a return to home feature, which I have set to kick in 10 seconds after it loses signal. I'm used to flying a flying wing with a spectrum DX6i that has a range so long that I'd lose the plane before I'd lose the signal, so I'm not used to having to think about signal strength. Is it worth it to upgrade? I feel like the camera controls on the Skycontroller black are worth it in themselves?

Well I picked up a Skycontroller 1, 3 spare batteries and a crashed bebop 2 off Facebook marketplace for cheap to complement my free (now no longer free lol) bebop 2. So now I have the controller and some spares. The crashed drone had a broken motor, but the owner said that’s the only thing wrong. We’ll see.

It’s a very rough guess but I’d say half a second? So you definitely cannot drone race in FPV with this, but for puttering around taking videos it’s more than fine. The nice thing about the parrot and something very different from the DX6i that I use to fly my fixed wing planes is that the throttle is self-centering like the aileron and rudder stick is, so “applying throttle” is really requesting the craft to go upwards regardless of what amount of throttle that takes. Also unlike a traditional drone, letting go of the elevator or aileron causes the craft to counter its movement and stop in air, rather than coast like a normal drone would. This means that you can just let go of the sticks and the drone stops. This is a long way of me saying that the lag is not very consequential.
