Electrohub with a bunch of DIY modifications to minimize cost and allow for easy repairs in case of a crash. I still have a long way to go for a stable AP platform, but I am slowly getting there.

I actually found the following FPV receiver/transmitter/camera combo at a garage sale for $45:

Iftron - YellowJacket 5.8 Pro Diversity Receiver with USB DVR

Iftron - Stinger Pro 5.8 250mw AVD Transmitter

600 TVL Camera

To do list:

Upgrade frame

Mount FPV gear

Upgrade batteries

Upgrade to GPS FC

I will post some flight footage soon.

Any suggestions?
