I did a 16 minutes flight with the RD32II and here is the result:
The form factor is definitively more interresting, with less drag on top of the fuselage. The 3 buttons are convenient to use especially because there is a virbrator that give you clear indication when switching on and off, starting or stopping filming.
Another great feature is the ability to connect the cam to a TV set and do all the settings easily. The downside is that you don't have a TVset at the slope, so once the mode, resolution and all other parameters selected, you cannot change them.
The Class 6 micro SD from Sandisk worked great.
Overall, this is a very good alternative to the GoPro 1, for 1/3 of the price ! However, the GoPro 2 made a step forward in term of quality and color rendering.
