Design and development

The KR-03 was designed as an ab initio training glider. The name Puchatek is Polish translation of Pooh Bear.{{cite book |last=Milne |first=A.A. |date=2012 |translator=Irena Tuwim |title= Kubuś Puchatek|edition=29th |language=pl |publisher=Wydawnictwo Nasza Księgarnia |isbn= 978-83-10-12033-5}}

The aircraft is made from aluminium with some parts covered in doped aircraft fabric covering. Its {{convert|16.4|m|ft|1|abbr=on}} span wing employs a Wortmann FX S-02-158 airfoil.

The Puchatek has a baggage compartment with a capacity of {{convert|5|kg|lb|0|abbr=on}} for soft baggage items.{{Cite web|url = http://www.ae.illinois.edu/m-selig/ads/aircraft.html|title = The Incomplete Guide to Airfoil Usage|access-date = 1 August 2011|last = Lednicer|first = David|year = 2010|archive-url = https://web.archive.org/web/20100420012244/http://www.ae.illinois.edu/m-selig/ads/aircraft.html|archive-date = 20 April 2010|url-status = dead}}
