The venerable JOULEBOX just got even better!
The JOULEBOX 190 MK II has been superseded by the JOULEBOX MK III.
Building on improvements already made in the MK II,
this version has been refined for additional weight reduction
and installation provisions for the Cobra 2203/28 brushless E36/F1S motor.
The JOULEBOX MK III 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 Cobra 2203/28 brushless motor, a set of 7.5 X 4 Graupner folding prop blades with a Texas Timers prop hub,
a 12 Amp ESC, a micro servo for DT operation,
an electrical connector set with 2MM bullet pin connectors for the ESC to motor connections and a Deans Micro single pin connector set for ESC to LiPo connection.

Design Features of the JOULEBOX MK III:
-
Wing construction includes built-in washout method to provide this important characteristic as you construct the wing.
-
8.8% Neemeyer flat bottom airfoil section is utilized for wing and stabilizer.
-
Custom designed spherical motor mount assembly makes thrust adjustments easy for power trim settings; something not seen on any other E-36 design to date.
-
Lightweight construction method that features interlocking features throughout.
-
The JOULEBOX as designed and flown by John Oldenkamp, one of the founders of the E-36 class of free flight competition,
proved itself in competition even before being kitted as the JOULEBOX 190;
We took the design and refined it even more for light weight, fast construction and even better flight performance.
Build a winner right out of the box and step into E-36 competition in the easiest possible way.
