The Howard DGA-5 "IKE” evolved from one of two almost identical prize-winning racers "MIKE” and "IKE” developed by Benny Howard in 1932. From 1932 to 1936 both planes won plenty of racing prices culminating in 1935 when Howard aircraft won the Bendix, Thomson, and Greve Throphy – a season of racing events that became unofficially known as "Benny Howard National Air Races”.

Ultimaker Cura is available for free. No need to spend extra money for a slicer software to get the "IKE" printed in high quality.
The model requires a minimum print bed size of 190mm/180mm/171mm. The provided Cura project and gcode files contain multiple model parts and require a print bed size of 240mm/200mm/171mm. Some parts can be simply removed from the project file in Cura to adjust the print area to your printer requirements.
Version 2.2 allows to (optionally) insert a carbon fiber pipe into the wing as extra robustness margin for cutting flight maneuvers. Some parts of the landing gear are reinforced as well and slightly increased louver openings in the fuselage further improve the scale impression. Last but not least, the engine side pull was increased to improve the take-off behavior.
