One of the biggest problems new drone builders encounter is shorting out their drone. They have no idea there is an issue, they plug in the battery, and the lovely plume of electronic smoke shoots into the air.
And just like that, their electronics are fried. They get frustrated, and never complete their drone build.
This is easily preventable with what I am including in this offer- a smoke stopper!
You simply plug this in between your drone and your battery when first powering up. If there is a short, the smoke stopper won't allow the surge of electricity to hit the electronics, and you can get to diagnosing the issue. The hardware is spared!
