This is the NEWER and improved version of the original OCTOblade hub--a 3D printable 8-blade propeller hub. This one is smaller and lighter, and is designed to use the DALPROP folding propeller blades. While this began mostly as a novelty item (and because nobody makes eight bladed 7" propellers), I think it may have potential to be useful in some applications. Balancing definitely needs to be improved.

LiPo BATERIES CAN BE CONFUSING!!!! But by the end of this video, you should be able to confidently purchase, charge, fly, and take care of a lithium polymer battery for your RC aircraft or vehicle! Helpful resources: Voltage chart: https://blog.ampow.com/lipo-voltage-chart/ Connectors: https://www.grepow.com/blog/exploring-lipo-battery-connector-types.html C-rating: https://www.batteriesinaflash.com/blog/battery-c-rating-explained-and-demystified/ Inexpensive one-battery charger: https://pyrodrone.com/collections/chargers-1/products/isdt-608pd-dc-240w-10a-lipo-1-6s-usb-c-universal-pocket-charger A solid two-battery charging option https://www.getfpv.com/hota-d6-pro-325w-15a-1-6s-dual-channel-ac-dc-smart-charger-w-wireless-charging.html ******* And here are the bullet points: 1. What the numbers/info on the battery mean
* Chemistry (LiPo) - (what kind of battery)
* Voltage (cell count) - (thrust/speed)
* Capacity — Milliamp hours - (flight time)
* C rating - (how quickly it can be charged and discharged) (Higher C rating will help give longer/more powerful "bursts" of thrust)
* Balance lead - (used for safe charging)
* Power lead - (main power connector to drone)

2. What to know when buying
* Connector type
* Voltage must match your specific need
* mAh does not need to be exact

3. what to know when charging
* Can burst into flame if overcharged
* ALWAYS balance charge
* Charge at a rate of 1C - (divide mAh of battery by 1000 to get the charge current in AmpHours) (1500mah x 1C = 1.5A or 1500mA)

4. what to know when flying
* Battery will be damaged if overdischarged
* If a battery is ruptured/damaged in a crash, it could catch fire
* Try to end flights with 20% charge left over (about 3.7V per cell)
* Don't fly with a battery that is very puffy or physically damaged ******* Want to watch this video without youtube ads? you can over at RCwithAdam.com 00:00 BLUF 2:43 What type of CHEMISTRY (LiPo)? 4:45 How many VOLTS (how powerful)? 5:03 What CAPACITY (how big)? 6:45 What is "C" rating? 9:57 Which type of CONNECTOR? 10:54 CHECK THESE 4 THINGS BEFORE BUYING A BATTERY 11:00 IMPORTANT SAFETY STUFF to know when CHARGING 17:09 What to know when FLYING 19:59 NO SAFETY PROTECTIONS 21:46 Storage charge after flying

Hiya, again! Building a water-lovin' FirstPersonView drone has been a bit of an obsession of mine, and I'm always getting a little closer to it! So today I'm testing a flotation setup and waterproofing quality for this 7" FPV drone. This didn't go smoothly, but it was an excellent, educational testing session. My mind is tingling with different design ideas to try. Most importantly, the waterfoofing seems to be holding up well (yes, I know I misspelled waterproofing, but it sounds so funny I left it that way. 00:00 Hello, Friend. BLUF. 2:32 Our watery adventure begins early in the morning 3:47 Turtlemode / Flip over after crash mode behavior 4:29 First flight 7:24 2nd flight 10:30 3rd flight (almost killed the camera guy) 17:11 4th flight

The idea was to see how this 7" FPV quadcopter would fly when all the motors are mounted with a forward 25 degree tilt angle. BUT because I didn't take into account the arm geometry of this particular frame (Source One V1 7"), as well as the extra wire length needed, the motors ended up being angle inward (front) and outward (rear). That's pretty weird, and not at all ideal. However, I wanted to see if it could still fly like this and how it would handle. I was surprised. If nothing else, this is a testament to how good/resilient/flexible modern flight controllers are!

The 3D print files for this angled motor mount are not available yet because I want to do a bit more redesigning so that they are more useful right away.

I thought it might be helpful to show the size differences between the new Radiomaster Pocket and the TX16S, TX12, and Flysky FXi6X radios. I'll also explain why I prefer this over the gigantic "gold standard" TX16S.

If you are using a Crossfire Nano Rx and AUX channels 5-8 (or, channels 9 through 12) are not working (but you know they SHOULD be otherwise), you may need to change your Rx into the 12ch mode. I'll show you how.
