Convergence: update to 4.5

[robertlong13]

The parameter file for this is old and is not minimized. I have upgraded it to 4.5 and reduced it to defaults. The formatting is a tad different, because I use Mission Planner to generate this.

Here is a log from a short test. Seems to fly fine.

While doing a motor test (to test ArduPilot/ardupilot#25670), I found a bug in the RFX. Output Channel 7 (the rear motor) has the Input applied twice. This means that the motor doesn't kick in until way late and saturates way early. I'm actually impressed it manages to fly okay with that broken.

Flight test after fixing still looks fine

Here's the diff of the actual rfvehicle file within the RFX to show that I didn't accidentally change anything else. The only other things that changed were subtle lighting differences (I guess) in the autogenerated thumbnail on export and some changes to the g3x.enc file inside there (I have no idea what that file does).

Actually, I take that back, fixing the RFX made the back-transition significantly worse. I'm digging into this some more.

[robertlong13]

I made more changes to the RFX.

1. Removed stray double input on Channel 7
2. Slightly increased rear prop diameter (slightly bigger than the prop on the real convergence, but wanted to get the thrust closer to what the front can put out)
3. Reduced front motor power from 200% to 70%.

The hover throttles for the motors match each other better now. Still plenty of power, and I didn't really have to adjust too much on the TECS for the reduced front motor power.

I retuned the hover and forward flight gains. Mostly because the changes to the RFX model needed this, but also its flying significantly better as a whole now than before. I'm very happy with it. Log attached:
