JOULEBOX 190
E-36 Competition and Sport Model



Build a winner right out of the box and step into E-36 competition in the easiest possible way!
 
The Joulebox 190 is the first E-36 turnkey kit on the market and allows for quick building and clear and simple setup for electric powered high performance free flight competition. 

The Joulebox 190 is available in three kit configurations to give you the most options to enjoy this design, see below for the  details of our Deluxe, Standard and Short kits.  

The basic JOULEBOX design proved itself in competition even before being kitted as the JOULEBOX 190.  The JOULEBOX was designed and flown by John Oldenkamp, one of the founders of the E-36 class of free flight competition.  We took the design and refined it even more for light weight, fast construction and even better flight performance and dubbed the production model the JOULEBOX 190
