This is my upgraded Vector SR48. I used a Fei Lun FT012 3500kv motor, 50a esc and a 11.1v 2200mah 45c battery. The green coupler is 5mm longer than stock and required due to the motor shaft being shorter. A T-PLug to XT-60 adapter makes it all come together. The speed increase is impressive while retaining the nicer qualities of the SR48.
