I did have the Pulse with the Himax 50 in it. I use the Makita Li-ion batts in a 6s1p config. Worked very well but I wanted something a little more aerobatic. Flies much like the old Trainermaster. Does the generic aerobatics very well but the semisymetrical airfoil limits it. but that's just my own take on it. Didn't have to beef up the landing gear as I had no trouble with it.
