Not sure what deals, if any, 3DR has with the Chinese wholesale market, but it is interesting that one wholesaler has a "genuine" 3DR APM V2.5.2 board with a jumper pad to enable / disable the…Continue

Carbon Fibre Brushless Gimbal for NEX and smaller.

I now have an RCTimer OpenSource BGC board ("Martinez") and a couple of LD-Power Gimbal Motors which are large enough for an NEX or smaller.  I looked over a number of BGC frames for sale but they all seem to incorporate metal or glass fibre, both of which do not have…

Just spent a couple of hours getting my head around the MultiWii V2.1 serial protocol.  This involved looking at EOSBandi's MW-WinGUI Visual Studio c# code and adapting the essential bits I need to a simple test VB 2010 app.  The app sends the commands to get the GPS bearing and distance to home as well as the Baro altitude.  The BT module connected to the Pairs…

I might go a step beyond this and get a new 2.4GHz Tx module and add that to the joystick to make it a transmitter.

Fly-Dream make an affordable and reliable…
