Big change from V1.0 to V2.0 is no longer resin printed. They now come ABS regular 3D prints. MUCH more durable and they come pre-colored now painting sanding etc no longer required!
Next change is the trim servo can handle higher powered motors due to a new linkage design. ALSO the trim servo can work with brushless outrunner motors now since they mount differently and dont need to ‘clamp’ to the motor.
You can still skip the trim servo and just adjust the trim manually but now its 100x easier to adjust then before, just 1 screw in the back under the motor cover.
