*Note the sensor may not work directly with the Vortex. The Vortex has a lower power supply to the ir sensor. If you wish to use it on the Vortex you will need to bootstrap the 5v power pin to the laser sensor.

Can you explain the bootstrap? or a quick schematic?

Good vibrations.

Sure, in the attached image (sorry its an old image), connect the red wire from the Laser module to the center pin of ACC2. Hope that helps.

Dear Drone Users,

Our AirTune software has been updated to perform simple 2 blade balancing.

Dear Friends,

We have just finished updating our Platinum software. The latest version now includes full functionality for balancing turbines. A lot of guesswork has been automated and you can now calibrate your test rig once and then use that data to run balancing on multiple rotors. The new code is located under the "Jet" button.

In addition, we are also working on a complete balancing system that will include a professionally manufactured balance rig. Watch this space!

I just bought the Impulse balancer. Can anyone tell me what to use for balancing weight for the EDF fans? What do you use and how do you attach the weight?

You can use epoxy putty. Mix it, apply it like a putty and shave weight off until you have the right balance. When it cures it will bond to the EDF surface. Only apply it to the inside of the center hub so it doesn't fling outward.

Sorry not an expert but can one use a self tapping screw instead?

I use aluminum duct tape on the inside of the impeller hub. Attach it in such way that centrifugal force would press it in even more.

Have ~100 hours of cumulative run time on 2 Eflite fans. Still holding on strong.

I would not use anything that puts holes in the rotor. Tape or glue applied to the inside of the rotor hub or spinner makes the most since. Like others have posted centrifugal force keeps the balance weight firmly attached.
