Thanks for jumping in with thoughts!!! Bluetooth is used between the PC and the handheld “remote control” and then it is a 2.4GHz signal of some type from the remote control to the receiver on the vehicle. From what I can find, even the older bluetooth 1.2 or so had a bit rate of 1 Mbps and in practice could transmit 700 kbps, so that should not be the trouble. The 3DR radio is only about 64 kbps and the serial connection to each end is running at 57.6 kbps. So theoretically, the Skydroid should be capable of a lot higher speed.
But, I don’t really know. It could be a Bluetooth issue.
You do make me think… I need to hook up via USB instead of Bluetooth to see if that changes anything. I will do that!
