EP 72. Tiny Tach Battery Replacement. For my Challenger 2 Ultralight Airplane

[@Russellsperry]

I have the exact same tach my paraplane, and this information is excellent 👍

Glad it helped

Interesting video....as always, but ONLY 360P? That´s kinda like flying at an altitude of 30 meters....in town 😂😂

KZbin is taking longer than usual to process the HD version. It was shot in 1080p, so the high res should be up shortly.

I’ve never used one of those mini spot welding tools, but I’m wondering if it could hurt the battery or the electronics? There are also amazing new soldering techniques I would like to try as well, but they seem to good to be true? As always I appreciate these videos 👍

[@challenger2ultralightadventure]

The current flows from one probe to the other, so the electronics and the battery are not effected at all. Don't use too large of a battery, as this kind of tool has no output regulation other than timing. A motorcycle battery or small yard tractor battery is about the right size.

AT THE VERY LEAST I CAN CHANGE THE BATTERY NOW AND THEY ARE AVAILABLE AT WALLY WORLD!

I LOOKED ON MY TINY TACH AND IT SHOWS IT IS ON WHICH GREAT BUT THE AIRCRAFT ISNT DONE YET. IS THERE A WAY TO TURN IT OFF.

[@challenger2ultralightadventure]

They never turn off. Battery is expected to last at least 5 years, some have lasted over 10. They are a great little unit, but now their are some others on the market that have replaceable batteries. Which I feel is a much better option.

[@tlcasey1002000]

AND THERE ARE A LOAD OF 12 VOLT SPOT WELDERS ON THE MARKET. LIKE THE ZERO LAB.

Tiny tach crap. They couldn’t have put a door to replace battery. Oh yes planned obsolescence I get it. I will never buy another one of these stupid tachs
