A superb 'funfly' power plant and with more than enough power for most .40 sized trainers. RCM&E magazine wrote of the MDS 38 Pro: This really is a sweet little engine. It clearly liked to rev and yet proved more than capable of pulling an oversized propeller if requested. The quality and performance is equal to and in some cases exceeds that of many higher priced units of similar size.'
  Prop: 9х6 or 10х6
