Fighting the temptation to get a Nano Goblin from RMRC. 92 bucks for the PNP. The 2s Li-on batteries being back ordered helps though. It seems close enough to my CTH Assassin I'm not sure it's worth it? I did not win. Or the R9m+R9mm combo for 55 CAD. Golluk fucked around with this message at 20:43 on Nov 23, 2018 |

I have zero time/use for a massive wing but after hearing one fly I wanted one so bad. They sound so dangerous.

We bungee launch ours with a pvc ramp and it works fine. I've seen a relatively new flyer hand launch an x8 though in full manual.

Was doing hand launches with a FX-79 Buffalo (2m) for a while for some mapping work. It sucked pretty hard. If you didn’t get the angle of attack and the speed just right it would snap roll into the ground and there wasn’t anything the autopilot or manual pilot could do about it. If you got it right it was fine and once in the air it was a kitten but after a few gently caress ups we switched to a plane with wheels. When lightly loaded it was fine but with a big camera and plenty of battery it was hairy.

No chainmail necessary for this lil' tyke I hope: I've soldered tinier stuff but the deep well cockpit and short wire length has made it kind of a PITA so far. Still waiting on an fpv cam, so this is just a test fit / configure stuff before everything gets hot glued in place. Also first time messing with crossfire, weeeee.

Looking forward to getting mine up and running. Sadly no idea when they'll have the 2s Li-ion packs back in stock though for it to ship. In the mean time, I'm tempted to get a ground based FPV thing going. Just not sure If I want to go REAL cheap, and get something like this, then swap out the Rx and add FPV. https://www.banggood.com/2811-2_4G-...r_warehouse=USA Or low end hobby level and something like this, which would definitely handle the cut grass fields I'm thinking of. The other one, not so much. https://www.banggood.com/Syaheli-112-2_4G-4WD-Desert-Off-Road-Truck-Eagle-3-RC-Car-FY03-p-984621.html?ID=228&cur_warehouse=CN

The 2s 18650 packs with the fatshark barrel connector are, from what rcgroups has led me to believe, the same cells with a call protection unit on one end. I opened the pack up and got rid of that and used the cheaper pack in the nano gob v and haven't had any problems so far Edit: oh, and yeah the deep narrow fuselage compartment really is the worst outside of dlg pods I've had to cram electronics into. bullets cure cops fucked around with this message at 17:17 on Nov 28, 2018 |

You can also just buy cells from LiIon Wholesale, some wire and balance connectors and XT30’s and heat shrink from the ‘zon, and make your own packs. It’s fun.

Just scrape the plating off the ends of the cell with a dremel before you solder to it, and do it quickly. It works fine. I built two 3S5P packs like this (11.1V, 15000mAh, total of 15 cells in each pack) for an endurance project and they came out great. A++ would spend a whole day inhaling solder fumes again

I've found just a really, really, hot iron, tin the cell first.. and lots of flux will do it. Batteries are serious heat sinks though, so lots of heat and fast. so while we're on the subject, where's the reliable place to get 18650 cells?

I have had good luck with LiIon Wholesale like I posted earlier. Although it’s been my only experience with 18650’s, all 32 cells I ordered did exactly what they said so I have no reason to believe they weren’t genuine LG. Their prices are as good as anything and they have a good selection.

Kids glider assembly thanksgiving weekend was a smashing success! I brought enough cut foam to make 4x planes and we each made one in about an hour and a half total. My 70 year old Dad even made one, which shocked me (because normally he would rather just look at his iPhone). We fitted two with flight controllers, 2x servos, receivers and batteries and had a good time throwing them around. Longest flight was only about 35 seconds though which I think the kids were a little disappointed with after the initial excitement wore off. I had also prepared the servos centered and with linkage stoppers so the pushrod bending wouldn't take any time, and I think that saved a lot.

I have a 2 meter plane (skyeye..) that needs a battery pack. :-) I like the idea of flying it on 18650s. I also need to pick up another APM.

Speaking of 18650s, I made a lot of Fatshark packs out of some new 3000mah INR18650F1L cells. They're rated for a max of 4.8A (ehh...) but perfect for goggles. They have a barrel jack on them, and a balance lead. I'm looking for mostly just the cost of parts, at this point -- so like $7 per pack + shipping? I originally got them to build a long-distance plane pack, but couldn't get them competitive with the 18650GA's.

My Rhythmic Crotch posted:What are you guys using to charge your 18650 packs? A standard lipo charger will do it in most cases. I'm currently building a 12S4P pack with a built in BMS and got a 50.4v charger just for that.

Hmm... I tried making a 4S pack of LG MJ1 cells a while back and recall my charger hated the pack voltage getting too low. I would have to put it in NiMH mode, trickle the pack up to a working voltage, and then charge it the rest of the way in LiPo mode. Super annoying.

Most chargers have a li-ion mode is what he meant. Don’t charge li-ion on li-po settings if you can avoid it.

And now I’m reminded of my dumb fat sharks and their fixed low volt alarm again and argh. Furious makes a supposedly smart case for 18650’s and it looks so fiddly and annoying, and will still alarm at 3.5. Literally all I need from you is a regulator that’ll power over the alarm voltage when cells are over the threshold, and under the fat shark alarm voltage when they’re not so the goggles will beep. That’s it. evil_bunnY fucked around with this message at 11:58 on Nov 29, 2018 |

The only part I don't like is that last bit because I always have to make soldered wire harnesses to go to the ailerons instead of just using off the shelf servo extensions. It also kinda sucks that the USB port is on the side so you either have to mount it facing up (roll=90) or cut a side hole for access. You can't beat that cost though for a first-class F4 flight controller. You also have to watch out when you buy them because the "Pro" has a linear BEC (yuk), the "V3 Pro" doesn't have current monitoring (I think this is actually just a lie that it is a Pro), and I've also seen "V4 Pro" and "V5 Pro" which are nothing like this.

The limit is 400 feet in the US, and a lot of people cover that up yeah. They also usually cover up their GPS coords just to prevent people from figuring out who they are and where they fly.

Is there a way to snoop RC protocol traffic from a second ground-based module somehow? I'd like to pull the telemetry from my FlySky receiver into a second device for recording and processing but don't want to buy a separate telemetry transmitter for the model itself. Surely there has to be a way to just passively listen to the telemetry data that's already in the air and being displayed on my Taranis. I looked around RC Groups and everything I can find there seems to be full-blown ground stations with way more equipment than I need. I was hoping I could grab like another iRangeX module and hook its telemetry stream to a microcontroller that does what I want, which is point my big mirrorless camera at the model and zoom appropriately for the range. I'm tired of trying to find a hat camera that doesn't look like awful when I have a $900 mirrorless with a tripod, servos, and all the GPS data I need already floating through the air.
