I loved my pepperf1sh. But indoors I was breaking a lot of props and leaving many marks on walls and furniture. And for outdoors i by far prefer my pepperfiish on the tinyshark frame. So I transferred the electronics from the pepperf1sh to the betafpv whoop-style frame. I designed a TPU adapter plate to mount 16x16mm hardware to the betafpv frame. Finally, I adjusted flexrc's 16x16mm cam mount to my needs. It is running betaflight with the settings from project mockingbird which makes this thing real fun indoors. The motors are the new style 0703 from boldclash (sealed bottom) at 15000kv. I fly for about 2 minutes before the 260mah 1s lipos come down pretty hot :). Maybe I'll try the 550mah 1s lipos once they are available anywhere. It weighs 25gr without lipo.
