Hi Guys,
Let me just say my postulation posted earlier is just that. I have no experience with using that many digital servos on one system using a gyro. ( I use 8411's and 8417's) I have not tested any of the voltage regulators out there. I am speaking from the viewpoint of general electronic engineering experience, much of which gained designing RC related sytems. These include our own ECU and GSU as well as RX's for long range use in target drones. Our ECU used a switch up/down switching regulator that can work from anything between 2V and 12V for the very same reason. Unless I analyse such a system close up, I would only offer it as a possibility. My main issue is with adding gizmos to a system not included in the design brief of the very good JR R&D engineers. But I hope the issue can be resolved before someone loses another jet. I did not see the impressive twin AMT Rafeale go in at FJ but I heard the very sickening sound of tarmac rash, reportedly due to a similar problem. The solution may be as simple as adding some low ESR high value capacitors in the Gyro voltage regulator circuit to keep the analog amps happy.
The need for good voltage tolerance on the RX is well taken care of on JR's. The RF section works from a regulated 3.3V
Cheers
