AK420 390mm Carbon Fiber Main Blades

Great for practice. Great price!

I’m running these on my TB40. I love Align blades, I even run them on my S2 max, but I like these a little better honestly. These feel a little more floaty and does better collective stops than the Align 380’s.. the style and finish of them is beautiful ! They match my Fusuno canopy perfectly! These are definitely a little louder and have a little more bark than the align blades.. the motor seems to get a little warmer, but nothing concerning.. I’m running the Hobby wing 60 and align motor that comes with it.. ive also ran it with these mains and the stem 74mm tail blades and haven’t had any clearance issues.I’ve bought 3 sets of these bad boys so far, very happy with them!

Went with these to try out a much cheaper option for main blades. Made a few quick flights and they seem to work just fine.

I'm surprised at the quality with its low marked price. This is actually a decent quality blade.

Needed some spare blades for my heli that uses 380mm. These worked great and are well made. The big yellow 'STEAM' logo is actually on the underside w/ just a small logo on the top. Perfectly balanced out of the package.

These are an excellent set of blades, balance was spot on, fit was perfect and the color is nice in the air. They make a little less noise I would assume from the shapped tip.
