 Flight characteristics were found to be pleasing, but before plans could be made for mass production, Iberavia was acquired by AISA.The new management decided to continue with development, but made a few changes to the design, reducing the size of the canopy, and replacing the undercarriage with a taildragger arrangement.This configuration entered production in 1952 with an order from the Director General for Civil Aviation for 70 aircraft for use in Spain's aeroclubs.
