Quadplane tips and hints

Hi Mathew, yes I just realized that you mentioned there max.weight is 4.5 kg. But I am surprised that using composite airframe (I assumed not EPO) with 230 cm wingspan and 2 hours endurance only 4.5 kg… This is excellent. May I know how big is your battery?

Lynx VTOL uses a pair of 99Wh batts.
