Yes, the FMS fans are a drop-in replacement. No need to change the ESCs either. I got them off of Banggood for about $50 each, shipped. They give the model a very noticeable increase in acceleration and vertical performance. It’s what the model should have come with stock. Another added bonus of these motors is they are each about 2 ounces heavier than the stock 1850 fans, which helps bring the CG farther aft with a big battery like the 6250 up front. Im getting consistent 4 minute flight times and landing at about 25-30%. Battery is warm, not hot. I’m sure they could benefit from an even higher C battery. These fans made the model feel sooo much lighter along with boosting the elevator throws to 125% max travel on much faster and higher torque Hitec digital servos.
