I have a F150 that can run it. Only tried it once, MPG were crap but the engine did have some extra pep for sure.
Even now I only run non-ethanol gas, and the mileage difference between even 10% ethanol usually makes up for the difference in cost.
I know on my Optimax there is a large cable with a built in fuse that protects the engine electronics. You can tell if that fuse is blown by looking at it. If it is blown, the battery will not charge. You cannot replace the fuse but have to replace the cable.
I always turn off advanced autopilot. Like you said, with wind it seems to zig-zag too much. I think on mine I can set it up to have it turned off all the time.
Cortisone is absolutely terrible for your soft tissues. One injection at a site would be max for me. I had an orthopedic surgeon tell me too much cortisone will make your soft tissues like a rubber band that has been sitting in the sun too long...it almost disintegrates when you touch it. Bad...
