Steam AK420

People this is a nice heli to build! Quality at a reasonable price. Smoth drive train, prefer the tail servo mounted on or in the frames is my only citique, so I altered it. cold for flying now I will update after some flying.

Great bang for the buck

I picked up the Steam AK420 on Black Friday. I can truly say that this heli is one of the best buys on the market right now. The build went smoothly, and the quality of the kit is astonishing at this price point.

Great value

This kit is well made and many of the more complex parts come pre-assembled. Would be nice if kit had an instruction book.

Best 420 made

Build, flight, and overall performance over 50 flights is the best I’ve ever flown.

Das good heli yoh!

Hasn't been flown or built yet but i'm sure it's gonna fly like a Dream. Still currently sitting on my shelf. Awaiting monetary funding for the electrics. Its an on going fulfillment goal.

Update: just buy it. It's a good heli. Just having issues, I want more cyclic, tho I'm running 14° of pitch. I'm limited mechanically. That's a me issue tho. Good n' cheap kit! Went together nicely. Some bits can be over complicated. All in all 4/5. Great ripper. Cheap to crash! Probably the cheapest! 420 is a weird size but good.

Best value for the money.

Went together easily. It flies like a much bigger heli. I really think its going to be a tuff little beater without being overly heavy. I though the gear drive was going to be loud. Surprisingly it is very smooth and quite. The only real complanate I have it the autorotation bracket have supper coarse self tapping screws. I believe it the only piece of plastic besides the landing and links. They keep loosing just enough to notice. Ill install a longer bolt with a lock nut on the inside. I think it will become 1 of my favorite smaller helis.

Very nice for the money

Durable where it needs to be. Fits together well. It has some ingenious, simple design in certain areas but overcomplication in some others, nothing egregious. I would prefer a different mounting system for the rear swash servo. It does have an external mounted servo for rudder, which I enjoy for ease of access. Very sharp looking. Started and finished my build today. Programming tomorrow with a maiden in the evening. Can't wait!
