ImpulseRC Alien Butter Kwad (Kit)


ImpulseRC Alien “Butter Kwad” (Kit)


Smooth. Just like butter!


Multirotor technology has been advancing at an unbelievable rate. Not long ago, the go-to method to achieve smooth flight with a multirotor was to opt for a large frame design. With the development of faster and more capable flight controllers on the rise, the size of the multirotors available on the market is decreasing. But how small do they really need to be? We decided to take a step in the opposite direction to find out.


Good Quad, Better Quad, Butter Kwad!


We started with the ImpulseRC Alien 6” frame, a tried and true multirotor design that has made drone history. It has set a benchmark for other frame designs. Electronic components are nowadays much smaller than they were a year or two ago, so the extra space isn't needed. Therefore we switched out the frame body for the smaller Alien 5” body. This makes for a slightly smaller and lighter setup that can still run 6” props, while pushing heaps of power and speed! It also brings most of the mass (HD cam and battery) closer to the center of gravity. The longer arms increase the leverage each motor has on the quad, adding to the "very planted" feeling when flying! The end result of all these factors was a quad that flew so smooth that we dubbed it the Butter Kwad. Oh, and it's so quiet! It makes a great stealth quad if you cover up all the LEDs. Perfect for those #guerillafpv flights!


Butter isn't Purple or Red


The gentle yet powerful flying characteristics of the Butter Kwad are unique, so we had to give it it's own color scheme. After requesting several color samples from our hardware supplier, we settled on the obvious choice: buttery gold colored hardware. We think it's quite fitting!


If you don't buy the hype, try it yourself!

Awesome Frame- But not so durable

First flight and I already have one of the arms that has the top surface lifted up in the middle of the arm. Almost like the top surface has been glued on and the glue has been undone. I love this frame and I give 5 stars for that but as for the arm doing this after the first flight, I am pretty disappointed. It was only one arm that has done this. May just be a defect in the 1 arm in the machine process but for the money spent I was expecting more durable carbon fiber. :(

Most frames these days are pretty good, the only things that separate them are overall quality , how much room you have, and where you want the battery. This is one of the good ones. It's so nice to have plenty of room and not be worried about components being squashed when the frame is assembled. Including diamond files is a nice touch, and overall build quality and fitment is exceptional. I had to lightly modify the camera plates to fit the Runcam Swift 2 (I had to file the back plate a bit to clear the connector block, and open the camera pivot holes on the side plates to fit the new camera's larger diameter standoffs). In hindsight, the alternative would be to use the additional case with a bushing/o-rings over the screw to take up the slack. I also used the Forever Tubes Antenna Mount from The 5mm version fits very tightly over the standoffs, the 6mm is a little loose and will need a sleeve of heatshrink on either side to stay put. The vtx antenna is mounted per finalglide's build video, so the vtx and rx antennas are in a nice V cluster at the back of the frame. Flight characteriatics with Kiss FC and ESCs running dshot600 through 2206 2300kv motors and 6040/2 props is so smooth, so controllable, but still had boatloads of punchy grunt and responsiveness. I am in love with this quad. It makes me want to just hang out and fly a few more packs.
