Mine is a Classic with wings which needed about 1000 man hours of careful effort. I built a crude insulated "box" and placed two electric fan heaters to blow hot air in through small ducts low down at either end, being very careful not to allow direct blasts onto the flying surfaces. In the early instruction manual was a warning from Ivan Shaw not to allow anything being cured to exceed 50C, lest the blue foam inside should swell and your carefully created masterpiece would transform itself into the proportions of a Snickers chocolate bar. Also, if the wing was supported on trestles and left unattended in excessive heat, the resin would soften above 50C and the wing would sag between the trestles. So it is highly recommended either to have thermostatic control of curing temperature, or to place a few thermometers against the pieces being post cured and to monitor the curing process at 15 minute intervals throughout the long hours. This I did by briefly opening the box each time and quickly reading the thermometers. I then adjusted the fan heaters as required, which meant that I was being the thermostat.

I know this might put the cat among the pigeons... I have self powered back ups - dynon has its own battery - Back iLevil with its own battery - hand held radio I have a crowbar and I believe that the rotax alt will generate a maximum of 18 amps on a very good day. The only things that dont have their own backup power is trim and prop. So would having everything wired into a single ON OFF switch present any drawback? This arises out of reaching out to my GPS and a sudden bump causing me to miss the GPS and turn off the bat (which I immediately turned back on). I have separate bat and alt switches .(which is probably not in an case the best arrangement I admit but leaving that argument aside for now). Th obvious thing to do is what is recommended by Bob N in the Z16 which is to have an OFF - ON (BAT) - ON (BAT+ALT) switch...but Im curious.

Using a 1,500 watt electric heater that oscillates back and forth. I had to disassemble and mutilate the thermostat to operate at temp required. Using a muffin fan to inflate and have several thermometers to monitor temp. Draping packaging bubbles allows yo to get temp just right.: http://www.europaowners.org/main.php?g2_itemId=27216 Works great and packs into a very small package when not in use. BTW check out inflatable painting in same folder. Ron P.
