BETAFPV Upgrade Lite 1S Brushless Flight Controller SPI Frsky D8 Rx Compatible with Silverware Firmware BT2.0 Connector for Tiny Whoop Quadcopter FPV 1S Whoop Drone

First and foremost, it isn't mentioned anywhere but this FC is expecting props to wash OUT, not in. Like a Inductrix FPV+. That means instead of the front left prop rotating clockwise, it needs to go counterclockwise, and all others reversed similarly. Otherwise, all yaw actions will be inverted and the quad will probably just spin in place, violently. There is a motor direction config page in the OSD, however it cannot reverse the control yaw direction as can normally be done in BF/CF CLI. This doesn't usually affect flight performance, actually sometimes decreases prop-wash, but is definitely something to be aware of in troubleshooting.After a few days of flying and tuning, I feel I've gained a good understanding of what is and isn't possible with this flight controller and it's included software.My reason for purchasing was to replace the betaflight FC that was included with my HX100-SE after accidentally bridging the 5v regulator to ground during a repair. I've been using a Spektrum TX lately, but didn't have any spare micro receivers so this seemed perfect as I could fly on my old X9-E and install a Spektrum RX later. It flies nicely, but I've never had a FC that I thought was actually bad at flight control. It works, but not how I'd like it and to me that's not worth spending $35 instead of $45.Airmode, if you'd call it that is always on, and has a very aggressive idle speed that can't be adjusted. While diving in acro mode, for example, the quad still flies forward probably 2 meters for every 5 it falls. It actually feels more like an old idle-up setup with no vbat pid compensation.Speaking of falls, when it does fall turtle mode is included but does not respond the way betaflight does, and has generally been much less effective so far. This is my first experience with Silverware, but from some research it seems there are usually more settings available on stock Silverware than are on this FC through the OSD menu. Therefore, tuning, for me will never be perfect due to parameters I'd like to change not being adjustable.I think this is best suited for horizon mode house cruisers, whoop racers and such where you just want to get flying and not mess around more than you have to. If there were an easy way to flash betaflight to it, or it were significantly less expensive than its betaflight counterpart I would definitely keep one as a spare in my kit to just throw in and get back to flying. The bottom line is that it's 75% the price and is missing much more than 25% of the features of a "normal" betafpv 1s betaflight FC so for now, I won't be buying another.

Put in the battery and it went up in smoke and now it doesn't work. No continuity so something burned up. Im not happy with this that shouldn't happen.
