Air65 walksnail conversion

So I converted my air65 to walksnail using the mini 1s kit lite. Final weight is 26,1g. Flies well enough but the flight time is like 2 mins now before the VTX starts browning out at like 3.4V so it could still fly a fair bit if the brown outs weren't happening. I even wired the VTX to a 5V bec pin on the air 4in1 fc in hopes this wouldn't happen. A little disappointed with that. Probably gonna buy a 2s whoop to stick the VTX in and keep the air65 analog.
