After seeing one of these first hand I just I had to have one and let me tell you after I received the steam 420 and inspecting all the components o was like wow I'm impressed with the quality and craftsmanship especially for the price. the build is precise and goes together with perfection. with that said I really looking forward to see what else come out the the steam camp. two thumbs up here.
D
This is a very good chopper for the price!! 👍🏻👍🏻
R
Great helicopter. great price.good quality parts. Flys excellent fews things I will change like the tail. but at this price it can't be beat If they keep the price for the kit and the parts at these prices it will be a big hit and a very wanted helicopter to fly I will by more ak420's and a ak700. Highly recommend it. The other brands better be paying attention.
B
Assembles easy, everything fits as it should. Parts appear to be good quality and very good price for parts.
Flies exceptionally well, and is perfect size for me as a back yard practise heli.
r

SteamRC AK420 PRO Helicopter Kit (with Blades)
E
I haven't finished this heli yet but the kit seems great. Instructions must be downloaded elsewhere. They are not great, but good enough. Quality of the kit seems really high.
M
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.
J
Best 420 heli for me...cheap enough and flys amazing 🤩
P
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.
