"fast shipping...great stack, I have this dame stack in 6 of my 5" builds"

Great for a Beginner

"First build ever for standard 6s on a Source One V6 frame. Very nice. I just used the Blheli-S firmware right out of the box. Works great. Flashing to the latest version of Betaflight was a breeze. I did need to de-select bi-directional Dshot to get the motors to spin correctly. Sounds like if one flashes BlueJay you can use filtering and eliminate some of the prop wash, better tune, etc. My brain is too smooth to care about that. I can get my quad screaming at 80mph no problem as is. Lastly, you’ll need a decent iron to work with those battery pads. My cheap $40 iron wouldn’t cut it. Got an entry level Hako, Kester solder, and SRA flux; life was good after that."

Best stack so far imo

"Best stack so far imo. Recently I burned a Geprc Taker on a 7 inch LR. Got the same quad, specs but with these Skystars F4 and no issues at all. Totally recommended."
