I have the Walkera G2D in the lightest plastic version. It works just out of the box with its own controller. But indeed a bit tricky to get the remote tilt function to work properly. But once set up, it just works although the plastic isn't as sturdy as metal and it starts to vibrate with a lot of wind speed. Other then that it's great value for 59Euros incl. shipping form China.
The FC40 with stock propellors is quite nose stable. It doesn't really need a 3 axis gimbal to get smooth pictures, only smooth operating. With a P2 with 9" props the yaw compensation is less smooth and you could see slight yawing movement in your footage (depending on wind conditions). At least that's the difference I noticed between my FC40 with stock props and my P2 with stock props. I tried the 9" on the FC40 but didn't like the result.
For telemetry you have to install a IOSD (mini) and a PMU upgrade board (quite simple DIY soldering). However, to see the IOSD data you need also to install a 2.4 or 1.2 GHz transmitter on the Phantom and a receiver on the ground end, connected to a display or goggles. For the PMU and IOSD Mini you will spend around 120Euro or Dollar together. There's a big choice in 1.2 and 2.4 FPV systems that start from 75Euro for a Tx/Rx set, screens come for many different prices starting at 50Euro, you only need 640x480 resolution which is very low cost nowadays. Car backup monitors are also fine. Some even come with a build in DVR.
