Re: Compass
CompassWell known problem in big metal ships. Apparently they used to sort it with some strategically placed magnets (or a big lump of steel)
Well known problem on airplanes as well. Even on fiberglass gliders with little to no metal components a compass will be noticably out of alignment if not corrected. (And TINY amounts of metal can already influence it.) A sunroof and aluminium roofrack are not going to cut it, there's still way to much metal in close proximity.
On aircraft the compass has a small tray for mounting small magnets or iron blocks, used to counteract the influence of the aircraft frame on the indication.
I doubt the LOHAN compass will have any sort of adjustable compensation built in. It would still be a good idea to slug it up a hill, set it on a non magnetic table (Preferably something you coble together from some old planks without using ANY nails or screws) pointing due north, power everything up and stand well back while noting what the compass reads. Then turning it 90 degrees, rinse, repeat.
On the video is also seems to me like the canard has some trouble returning to neutral after making a full deflection. Is this just an illusion or is the servo drawing much more power at that point?
