The quality of motors is rather subjective, but here is a list of motors and their general quality:
Table 30.6. Motor quality
Quality Manufacturer
Best Plettenberg, Lehner, Actro, Neumotor
Better Hacker, Kontronik, Mega
Good Multiplex Permax, Astroflight
Fair Himaxx, Feigao, JETI, Model Motors AXI
The motors in the best category are relatively efficient over a wide load range.
The Kontroniks are slightly better than Hacker for helicopters due to better part load efficiency.
30.3. Motor selection table
Here is a table of motors sorted by weight to make motor selection easier.
