Heads Up On Board Quirks
Posted: Mon Nov 16, 2015 4:04 pm
Just in case anyone else out there bought/buys a RTF Quads Mega Multiwii Pro 3 "Blacked Mag" edition FC, there are some quirks and inconsistencies in the instructions provided on re-flashing the board.
For anyone who doesn't know and who may be interested, the "Blacked Mag" edition is a MW Pro much like the HK Pro but the mag has been removed. The board has no mag at all. Why? It is designed to work with a remote mag on a GPS unit. As far as I know this is the only Mega board out there that can run a remote mag. On this board, the GPS plugs into serial 2 just like a HK board, but the mag plugs into the I2C.
On the RTF Quads sales page for this board they state that this board, if to be re-flashed, should use the following board definition: FFIMUv43
Trouble with that is there is no FFIMUv43 in the boards list. The RTF Quads MW Pro 2 uses FFREEIMUv043. Trying that on the Pro 3 it does nothing like it should. Using that definition, the Gyro stops functioning, and there is no sign of a mag anywhere.
After I dropped Paul over there at RTF Quads an e-mail asking WTF, I got busy trying to resolve things on my own. Turns out that my solution was to recomment ALL board definitions. Then using the independent sensors section, I uncommented my sensors. Wow, hey, it worked!! Trouble was, everything was still messed up (without my knowledge yet) and when I tried to fly the quad did a beautiful flip landing squarely on the prop shafts.
More investigation using the GUI revealed that the sensors were not responding correctly. I used the section right below the independent sensors to enforce my individual sensor orientation. After working with the quad and GUI I got everything responding properly. Test flight later today.
I'm having trouble grasping at how they can give that BS definition on that board. I reviewed the board on his site but he has not yet published my review.
