Nitroplanes and Xheli have a new line of higher end servos called the
Solar Servo brand. Based on dissassembly, these are made by the same
company that makes the EXI servo line, Batan in China. I
3 types of servos to test and will review them here. I got in
different sizes: 2 Micro, 3 Mini and 2 Full size servos.
Much like the
EXI servos, the Micro and min servos have foam tape on the bottom to
secure the board and wires from vibrating and comming loose during
flight. The full siz servo has the wires silicone glue'd into
place. Overall, I found the mechanical contruction of these servos to
be sound and much better than the contruction you see on budget servos
like the Hextronics or Tower Pro servos.
Centering is the
ability of the servo to return to the same point when commanded by the
reciever. I compared the Micro and the Mini servos to
cooresponding digital hitec servos and the Standard servo to a budget
Hextronic to show how well the Solar Servos are doing with centering. I
was very impressed at how well the centering was with the Solar Servos
compare to even the Hitec servos. In all 3 servos I tested,
was difficult to see any error in the centering from the Solar Servo.
The Solar Servos did as well or better than the hitec servos.
In a test (not video recorded) comparing it to coorresponding
servos, the Solar servos did better than the EXI servos with the Hitec
servos doing better than the EXI servos.
