Safe, Tested Changes to Ardupilot for SV 2450GPS
I’m a retired system programmer but a newbie to rc quads. Got a small SV quad for Christmas and I haven’t looked back. The 2450GPS is the third quad I’ve gotten and I love it. Been learning and flying the 2450 for only 4 months.
The SV web server is so cool but way to easy to fu. I’ve learned a few dos and donts and wanted to pass it on to help newbies, especially kids and non-programmers.
Under Actions on the SV web server, TMode_Action 1 thru 6 below are my personal favs but you can set them to whatever flight mode you want, except TMODE_ACTION3. It defaults to disarm and I recommend leaving it as is, although you can set any transmitter button sequence to disarm. The power button is the easiest and most logical. Turning off the motors quickly when you crash is very important. As long as you leave it set to disarm, it will always work whether you’re flying or not. TMODE_MODE1 is the initial flight mode when you first takeoff. It defaults to Loiter, I just like PosHold better. Don’t change this to an expert mode like Acro or Sport. I recommend AltHold or PosHold. Don’t get confused about Indoor mode on the transmitter because indoor mode doesn’t really exist per se. Indoor is really Loiter without GPS.
Under Tuning in the web server, PILOT_ACCEL_Z is the vertical speed. It defaults to 400 but I increased it to 500. This is your choice, just keep it reasonable, probably best to stay between 200 and 700. Haven’t yet found the actual rate in cm/sec. RC_FEEL_RP defaults to 50 but could be 1 - 100. The higher the value, the quicker the quad will respond, particularly roll and pitch. The lower the value the smoother the quad will respond.
Under Radio in the web server, BRD_RADIO_TXMAX defaults to 4. The value can be 1 - 8. This is transmitter signal strength. I noticed when my quad was over 100 feet away, there was a half second delay when performing roll and pitch. Increasing it to 7 resolved this problem. See below:

More parameters will be discussed in the days to come.
