We love the ingenious design - there may well be a Doctoral Thesis in the way that this flies in such a stable fashion.
With its two blades mounted on flapping hinges and skeletal propeller bar, it is one of the most unlikely things ever to fly. Well, fly in such a stable manner, anyway. The delta-3 offset and mass balancing are part of this, and the technology used forms the basis of its highly educational aspect. A truly unique and very clever design.
So how does it go in the air?
We agree that it is stable (does not fall over) in flight, but does it do what is commanded on the remote control?
The short answer is, eventually.
There is lag in the control response that calls for anticipation of that delay, otherwise there is a tendency to over-control. The simple push-button direction controls are on-off in nature - so no great precision is possible, and the power control is linear but tends to lag due to the delay in spinning up/down of a fairly big rotor. So if it is plummeting towards the ground, it can start spinning harder just before it hits! That is, if you remembered to keep the controller aimed at it.
You *have* to keep the controller aimed at the machine all the time - this takes more getting used to than (say) the popular Picoo Z.
The instructions state that this is for indoor use only, and we agree. It has a very low forward speed, and the lightest breeze will blow it away. But it does prefer a big room, and we ended up in the biggest bedroom in the house to avoid all the clutter and ceiling lights elsewhere in the house. It likes conservatories, and a barn would be ideal.
It does not like ceiling lights that hang down - they seem to attract it, then knock it out of the sky!
But it's tougher than we thought. Ours is now over 3 years old, and the battery is now stuffed, but whilst it was good the Bladestar just kept on flying and is still in one piece. I keep meaning to extract and replace the old battery... Maybe one day...
Comes in a strong plastic carry case that protected it well in the mail, and is well up to the job. You need to remove the blades to store it again, NB.
Loads of fun if you can relax and get used to the delayed control response; a highly technical solution to a minimalist helicopter at a reasonable price.
Recommended for those interested in unusual flying machines. This tiny aircraft is as far out as it gets, and it works, albeit not perfectly.
