This is a long term slow build))))
But it is actually the neatest build I've ever made.

The build is based on the Flywoo Explorer LR 4 inch frame, with custom components. And running iNav.

Because it is made with iNav in mind, I had to add a separate magnetometer (compas), bacause the smallest GPS I had does not have one.

The build it's on final tune, and after maiden, I will add (maybe))) the statistics of flights with 4s Li-Po 850mah and with 4s Li-ion 3000 mah
