Designed with the help of the ExpressLRS team, theย Happymodel Pancake AIOย is aย true all-in-one flight controller. The Pancake comes with an onboard 2.4GHz ELRS SPI receiver as well as a 5.8GHz OPENVTX. Mounting options include both 30.5mm and 20mm spaced holes. With a price point comparable to most AIOs without a VTX onboard, you’re getting more out of your board at a lower cost. It is a great cost-effective FCย replacement.
