Can't decide
I have the Hot Hots and it flys beautiful. I also have the OMP 540 P . I can't pilot either one to their capacity but I give the OMP 540 the vote. I have the new Magnum 52 XLS on the 540 and the vertical is out of sight. If I remember the 540 was $60.00 but I changed the wire landing gear to composite, and that added a few $. I would say you probably would be happier with the 46 on a pipe for a better climb out from hover.
