I couldn't possibly be happier with this frame! This is a VERY light frame and the carbon quality is the best I've seen so far. Its shockingly stiff for how small it is. I think the short arms really make a difference with strength too. Everything by this designer is pure gold by the way! This frame blows every other lightweight 4 inch frame out of the water. I used to use the superlight 4r by catalyst machineworks, but this frame is sooo much lighter and more aerodynamic. I shed nearly 20 grams switching frames using the same electronics. The sl4r had wide, thin arms that werent particularly strong. This frame has narrower, more aerodynamic arms, but they are shorter and thicker which seems to make them stronger than the arms on the sl4r. Its actually noticably faster too! The Quattuor takes lightweight and low drag to a whole new level. This frame is actually almost identical in size to most 3 inch frames, yet it fits 4 inch props perfectly! I cant wait to try the 158mm stretched version and the 3 inch tribus by this designer. If you are on the fence about trying his frames just do it! You wont regret it! Just make sure you are comfortable with tight builds. It can be a little tough to fit everything, I had to split my stack and mount part of it to the top plate so that my canera would be able to angle backwards into the gap. You also may need to use a file just a little bit for everything to fit flush. This is a good thing in my opinion because this way I can make sure everything fits snug.
