JOULEBOX 190 MK II
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 MK-II is the only 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 MK-II is available in four kit configurations to give you the most options to enjoy this design:

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.




The venerable JOULEBOX 190 just got even better!

The JOULEBOX 190 has been superseded by the JOULEBOX 190 MK II. In addition to other minor changes, it has a redesigned fuselage with lower pylon, smaller fin and cleaner front end with an enclosed battery compartment. These changes make for a cleaner installation of the electric drive train.

The JOULEBOX 190 MK II is offered as a Short Kit, a Standard Kit and two Deluxe Kit options.

Deluxe Kit Option A comes with Starlink-Flitetech's electronic timer.
Deluxe Kit Option B comes with Texas Timers eMax electronic timer.

Both timers come with the optional RDT pigtail for use with your RDT system.

Both Deluxe Kit options come with all the other necessary drivetrain components (with the exception of the LiPo battery which the builder must supply). This includes a AX1806N brushless motor, a set of 7.5 X 4 Graupner folding prop blades with a Texas Timers prop hub, a 10 Amp Hobbywing ESC, a micro servo for DT opeation, an electical connector set with 2MM bullet pin connectors for the ESC to motor connetions and a Deans Micro single pin connector set for ESC to LiPo connection.
