we just used a kit for the DLE-35, which is the motor we used. I think this is the one:
it wasn't really reliable actually. Brushed motor, and the brushes failed once, the terminals broke off twice in cold weather with vibration. We just replaced with spares as needed.
there is heaps of room in the porter, and it only flies horizontally, so vib isolation is easy. We used an aluminium plate suspended on small cubes of dubro 1/2" foam, with another layer of foam blocks above that then pixhawk1 above that. Worked fine, but quite bulky. I can send photos if you like, but I wouldn't say its a great setup. Worked for what we needed.
