As you may know; Norway is not known for long stretched beaches, clear warm water or big palm trees - but cold, COLD, climate. And now that fall has "fallen upon us" as it were, I'm not laying down the radio just yet!
So I went ahead and ordered a radio glove (or radio mitt). I also got some heater elements which can be powered with 7~12 V batteries.
Heating elements, control box, wires and temperature sensor.
Trying out for how the wires should be placed around in the mitt.
Velcro tape for mounting.
Velcro taped to the bottom of the mitt.
Applying my master sewing skills
Heater elements in place.
Stuffing temp sensor inside one of the holes were a element wire comes out.
Zip ties.
Securing the control box.
Performing initial test with a 2S lipo, using alligator clamps. (Indoors).
This is before connecting battery. That's 75.2 degrees Fahrenheit, for you Americans
About 5 minutes after, at 70% power.
(80.6 degrees Fahrenheit).
Initial test success!
Went to my LHS and got some JST connectors.
Soldered.
Shrink wrapped.
All wires in place, devices secured.
The 2S lipo is to just lay beside the control box.
Outside tests, with actual flying.
Outside tempereature.
(59 degrees Fahrenheit).
After the first flight I raised the power to 50%.
After my second flight was finished, the device was off - and the 2S 1000mah was completely drained!
And no change in temp either
Can't say the outside test was a success. I did feel some heat radiate from the elements, but the glove was not "filled" with warmth as was my hope. The mitt did it's job though, I didn't get as cold on my thumbs and fingers as I would with no mitt.
In the initial tests I did try a 3S lipo, and that really put some juice through the heaters! Actually I was afraid the thing would catch fire BUT, as I see now, the 2S may not be the pack for the job - so I might do a 3S set-up none the less. We'll see.
