COB Strips

These are cob strips designed for your whoops and are PERFECT for UWL. 

13.75” is the exact length I use to do a full wrap of a Meteor75 frame. It weighs about 1.83g after removing the adhesive and paper peel  

16.75” is the exact length I use for a Mobula7 v4 frame. It weighs about 2.08g after removing the adhesive and paper peel.  

14.75” is the exact length you want for a Meteor75 Air to be fully wrapped. A strip this length would weigh about 1.9g after removing the adhesive and paper peel.

13.75” is the length I’d recommend for a Meteor75 air if you want it mostly wrapped but need to save weight. If you want a full wrap, you’ll definitely want to buy the 16.75” as the 13.75” is too short. If you cut off 2 segments from the 16.75” strip, it will be perfect for the air frame. 

Note: because of how cobs work, the colors of the cob strips are a different color than the light that comes from them. For instance, white cobs, which shine a bright, white light, actually are a little bit yellow in appearance when turned off. This is simply the nature of cobs and really, LEDs in general. This isn’t something exclusive to this product; you will see this with any cobs.

If you’re worried about making sure your whoop looks great when it’s plugged in AND when it’s off, use the information below to help coordinate colors. 

White Cobs: Yellow when off

Red Cobs: White when off

Blue Cobs: White when off

Green Cobs: White when off

Pink Cobs: Orange when off

Ice Blue Cobs: Yellow/Green when off 

You can expect the 13.75” strips to be about 2g of weight, once you remove paper peel, the goo adhesive, and apply e6000 across the whole frame. You can also leave the goo if you want extra secure adhesion and/or a little more weight. The goo alone weighs about 0.15g on the 13.75” strip  

To install, first, peel back the paper peel and a little bit of the goo from the end of the strip. You may remove all of the goo and the entire paper peel at this time if you want, but you at least have to peel back enough paper and remove enough goo to uncover the solder pads. 

Note: If you do not remove the goo, you won’t be able to solder to it. The goo is hard to see, but it completely covers the solder pad so you must remove enough of it to uncover the pads, or you won’t be able to solder. 

Solder a wire to both the 5v and GND pads. You can use pretty small gauge wire. However, I usually opt for at least 32awg silicone wire as I find it to be more durable and longer lasting. It might be overkill for what these cobs need but I would rather have the durability.  I’ve used 38awg magnet wire and it tends to be a fail point very quickly. 

Once the wire is soldered to the 5v and GND pads, start using e6000 to cover the frame and the cob strip, doing just a little bit at a time. Use baby clothespins, zip ties, tape, or another method to hold the cob strips in place while the glue dries and you move on to the next section. If you try to apply glue to the entire frame at once and apply the entire cob strip at once, the e6000 will likely start drying before you can finish and won’t give ideal adhesion. I find it helpful to use a toothpick to apply e6000 to only about 1/3-1/2 a duct at a time, using a clothespin to hold the strip in place, then doing the next half of the duct.

Note: regardless of whether you leave the goo on the cob strip or not, using e6000 is recommended as the goo does not give enough adhesion to be ideal.

As you’re gluing the strip to the frame, make sure the strip is pulled tight or you will start to see gaps where the bottom of the strip doesn’t come into contact with the frame. If this happens, you’ll have to go back later and use a toothpick to apply e6000 in the gap for ideal adhesion, which can add significant weight  

Once the strip is fully applied, you can cut the wire down to length and solder to your flight controller. Most people, including myself, use the top side of the pads used for the battery lead. We typically do not use the 5v pads as these cobs seem to be absolutely perfect on VBat and using the 5v regulator could put unnecessary strain on it.
