For lighter airframe, this might work. I loaded SV controllers on very old geared quad frame. All up weight is 124g, 19g lighter. Tried indoors only but flew ok without changing PID so far.
This frame is very old WLtoys V959 V212 V222 parts which I played as light acro quad before (https://youtu.be/W5OywFelzMw).
I do not see this sold any more, but see similar one available and I got one of them, mold is different but construction is similar. You can find as ‘CW CCW Motor Propellers Body Frame Gears for UDI RC Quadcopter Accessory’ at ebay.
