GWS has just released a new economically priced speed control engineered specifically for the burgeoning number of slow and park flyers out there. The GWS GS400 15A speed control is primarily for use with park flyers, such as the SFM Soarstar, but can be used with slow flyers as well. It is fully proportional and includes an "auto shut-off" feature that saves battery power for the receiver by shutting down the motor when battery power dips below a certain level. Available now.
