Simple Mobius FPV

...cheap and effective

For a while I've been considering getting an FPV system but, with the complexity, cost and choice of systems and components out there, I had deferred on the matter indefinitely.

A few things bothered me; firstly having to have two cameras because the supplied FPV cameras only supply video without storage capability. Secondly goggles; purported to be the best to provide an immersive experience but having low resolution and a limited field of view for the most-part, unless you're happy to spend the best part of $1,000 on HD goggles. And having to buy corrective lenses separately if you wear glasses.

Then I discovered that they'd released a Mobius Docking Station with a built-in transmitter. This takes care of getting the video stream from your mobius while still enabling you to record as you would usually. All that is required is a 2-4S power input on a JST plug, making it a simple plug-and-play application.

Next, reviewing FPV screens as a cost-effective alternative, I came across the RX-LCD5802, a  7 inch FPV Monitor with a 800x480 screen. What's nice is that is has integrated 5.8GHz 32CH diversity receiver and built-in battery. Furthermore, the screen image is clear and bright and it has OSD and an auto-search facility. Only, get this off eBay; the same thing just much cheaper!

The net result is remarkably simple and effective; connect the antenna to the dock, slide the mobius into the dock and connect a power via a JST lead. The mobius should power-on automatically and you'll now be transmitting video!

Then, screw the antennas onto the RX-LCD5802, hit the power button and within a second you'll be seeing crisp clear footage straight off your mobius.

It's as easy as that...

Spektrum DX6i. Rates & Expo.

...how to set up rates & expo

The DX6i has programmable Dual Rates as well as Expo, features not found on the DX5e and other basic transmitters.

D/R Expo is on the Adjust List, just under model select. Clicking on this takes you to the D/R Rxpo setup page, where the middle column is the Rates i.e. the servo travel percentage, and the right hand column is the Expo, which is set to INH (inhibit) by default. 

Clicking on one of the INH values and then scrolling will change this to a percentage value; the higher the more damping around the centre of the stick.

Dual rates allows you to set the travel of each control individually, and there is a switch for each as well to enable you to selectively change control travel e.g. setting elevator to "high" while leaving aileron and rudder on "low".

Clicking on a percentage in the first column will allow you to adjust the Rates, or servo travel, individually for each control. The actual amount will depend of how much response you require or how sensitive you plane is.

It's worth researching this before your first flight, as super-sensitive controls (aileron especially and also elevator) can be disastrous...
