Quanum DIY FPV – Fully Integrated Receiver

The Hobby King Quanum DIY FPV Goggle Set with Monitor is a cheap FPV headset but if you use the provided wiring with an external video receiver it ends up a bit cumbersome.

To make it easier to use, I embedded a RX5800 video receiver right in the screen leaching power from an existing regulator.

Leaching power seemed to work fine for a bit but the receiver started to work intermittently. I think it was drawing too much current for the existing regulator. I threw in a LM7805 with a 10uF cap on the input side and 0.1uF cap on the output side. Given the internally mounted receiver and regulator I may need to add more venting but I’ll give it a try as is for a bit longer first.

I insulated the screens pcb using some electricians tape and hot glued the video receiver into position.

I velcro and strap the battery onto the headstrap (not shown) when in use.

Tricopter – Airframe Selection

The RCExplorer Tricopter V2.5 appears a strong option. Unfortunately, when I was ordering bits the motors they recommend were not in stock. Not wanting to munge my motor/esc/batter mix, risk being under/over powered or otherwise messing up, I decided to skip this design.

Upon further research the INFINITY T3 – DIY Carbon Fibre Tricopter looks like a great option. It appears to have excellent 12-15 minutes of battery life and looks to be an excellent platform for putting a GoPro on.

The official design is made primarily out of carbon fiber. My initial go of it will be out of wood to reduce expense when I inevitably crash it. Once my flying skills improve I’ll upgrade the frame.

The T shape appears to provide better visual orientation than the Y designs which is a plus.
