For 1s eflite batteries, if they are in a charger and the charger says they are charged, then they're charged. Otherwise, they need shoved in a charger. Bigger ones, it's just two piles and a multimeter, I really should be more organized and keep track of number of charges, but  .

Martytoof posted:Speaking of batteries -- How do you guys keep track of your spent batteries vs fresh, when you go out? Just curious. I use the rubber caps that batteries usually ship with over the XT60 connectors. If there's a cap on the connector, it's charged. If not, it's spent. Pretty fool proof since there's no chance of me putting the cap back on a spent one in the field. For the ones I don't have the vinyl caps for I just 3d printed some xt60 caps and use those.

I'd swap it. the QX3d takes different batteries than most of the eflite stuff. Though.. the nano qx2 uses the same batteries... so.. maybe?

The QX 3D is usually cheaper from what I've seen. I've flown my friends before and think it's a lot of fun but I've heard of some issues with the quality control regarding them. Also the propellers are a bit more expensive I think and there's not any cheap china propellers you can get that I've seen. Also wow didn't know they released a Nano QX2! I Got my Nano QX FPV in December. Oh well not that much has changed on it but it looks neat. Granted I just watched a video and it didn't click before that it uses the QX 3D Battery. That's my one major dislike of the Nano QX FPV minus the crappy motors it comes with, the flight times are very short. Looks really cool Opinionated fucked around with this message at 11:26 on Apr 7, 2016 |

I'm looking to upgrade my ECSs and motors from the cheapo babbie's first quad kit I got a while back. To check my understanding, a 2204-2300Kv motor will have 2300 RPM per volt. Therefor, to get the most thrust, the higher the Kv the better. However, I've been reading that lower Kv's will provide more torque if your voltage isn't high enough. If I'm flying a 250 quad with a 3S, 5x4 props laden with a FPV and recording cam, should I be looking at the biggest Kv I can get? I'm thinking of upgrading to a set of 4S batteries, should I do that before I upgrade the motors?

You'll see some BIG benefits going to 6" props, if they'll fit. Or going to 5x4.5.

 I just bought a whole bunch of spare 5x4s. The arms installed just *barely* fit 5x4s. Ironically, I have a second set of arms that could fit 5x4.5s easily, but the motors I have don't fit the mounting points on those arms.

Erm those are both 5 inch props, there should be no difference in length. The 4 vs. 4.5 is the pitch. In any case if you go straight to to 5x4.5 without upgrading your motors or ESC's, you might actually see worse performance (or worse blow an ESC if the amp draw is too high). I dunno what your current setup is though. You need a lot of power to push those aggresive props.

Wait, I thought the .5 was indicative of a bullnose prop? Either way, assuming I stick with the 5x4s for now (At least until I break them all) and go with 20A ESCs, should I go with the 2300Kv or the 2000Kv motors? My instinct is to say mo Kv mo betta mo fastah, but some of the finer points of this are most likely eluding me.

Nah it's just more pitch. 40 vs 45. Bullnose props will be labeled as such, like the gemfan 5045BN's (and are even more aggressive). Bullnose or not, it's still 5 inches and should fit fine on your arms. I'd go with the 2300 for 5" props.

thats a lame price for last years ESCs and motors.I feel like you could do better elsewhere, even in the US rmrc's t motor and somewhat newer blheli ESCs (maybe littlebee, maybe ztw spider, not sure) is $160. Their DYS combo is $90 but I don't know how much nicer than what you currently have, that is. edit: hell, you could just buy 4 of the emax red bottom 2300kv motors and the xm20a ESCs for less moron izzard fucked around with this message at 21:26 on Apr 7, 2016 |

I'm running 6x3's on 1806 2300kv motors. I've done some testing, and found that they're the upper limit of what the motor can spin at low speeds. Actually, there needs to be some good data posted of this. That said, I've got a motor test stand, and a bunch of motors that are ready to test. DYS 1806, Multistar 1704, emax 1806, and... I can't even remember most of them. And I have data from testing the F550 airframe motor... Is it wrong I want to sell testing data? Instead of just giving it away.

The question is whether or not people will pay for it. For the mini quad hobby crowd I think you'll have limited success. However good thrust and power data of quality non-Tmotor prop and motor combos can be hard to come by so you may get some people from the industrial and custom UAV building crowd looking for that info (but undoubtedly for motors that are larger than you'd probably have)

I recently went through with registering my quadcopter with the FAA and I'm pretty upset with the process they've got set up. Basically, anywhere I could potentially fly my drone is within 5 miles of an airport or heliport. So I went to work gathering contact information from all the airports and heliports that could possibly be in my flying areas and many of them are so small they don't have a tower or control center and some "airports" are just loving grass fields, one with a phone number that appears to be disconnected. I can't even fly my drat thing in my backyard without violating the FAA regulations unless I can make notification and not be be blocked by these airports from flying? So I've been trying to learn as much as I can about this whole thing because I don't understand how the FAA can regulate the airspace in a private backyard, but has there been any progress with some of the lawsuits going on over the registration process, and should I expect these rules to change anytime soon? Are you guys having trouble with local airports or small airports that presumably have no way to contact?

Start looking into the atom 122 frame and similar sizes (my fav is the insect 130 from banggood US), and 1105 series motors. 6500kv and they rip on 2s and kill on 3s. most craft end up being under 150g WITH battery. So you're under 250g and gently caress em. I know this is probably not a good answer or solution.

Is it a small craft you're going to keep in your backyard or a park, probably below the tree line? I'd suggest not giving a gently caress is your craft geofenced and kept from taking off? make a tinfoil hat and follow my previous steps. I googled around about this for a while and found some sites that would list phone numbers, but literally every convo I read about others experiences actually calling people have been either "ok," or "why the gently caress are you calling us"

So you're under 250g and gently caress em. My understanding was that the 250g limit is for needing to register aircraft. Anything under 250g still has to follow all the FAA guidelines (including staying away from airports), but I really doubt anyone would care about someone flying a 250g drone in their backyard.

So you're under 250g and gently caress em. No, in fact maybe looking into sub 250g is the way to go. But I'm more into the aerial photography aspect of drones and not just flying them. Most of the features I want from an aerial photography drone are on phantom sized units. I just don't think I should need any sort of authorization from any agency to fly in my own backyard or private property that I have permission to fly on. Basically, having to contact any and all airports within 5 miles as a hobbyist is onerous at best and prohibitive at worst. I don't think just saying gently caress it and ignoring that aspect of the registration guidelines is the way to go. I haven't had a problem yet, in one case I called the airport number and left a message that was never returned. There are 4 airports in my home area and having to notify them each and every time I fly, or work out some long term agreement, is asinine.

Yes, a "good" transmitter makes a world of difference. post here if you make that decision. I probably have a DX6i to get rid of, and I'll do a goon price. Beyond that, it's time to pick up a 250 class FPV rig. They're fun to build.
