I ordered a Tekin combo today and ordered it with the 2050 motor. Is their a big difference between this and the popular 1900? I also ordered a Reedy 4s 60c battery. I have a friend with an SC8 that has a Castle 2000kv with a Reedy 4s and his is crazy fast. I will be racing against him in the unlimited class. With my rc8e factory team with this motor/battery be close to his SC8? Thanks Also what kind of servo should I buy?
