I bit the bullet and ordered one. Looks interesting, can't wait to see the fedex man drop it off.

The helis from that company have not had a good record in regard to being able to fly
I would hold off a littel until it is a proven performer. The 300 sized sparrow struggles in the air and this just looks like an enlarged version of it.

Hey ozace, when you're talking about the sparrow, is that the same bird as the aplus?

According to what I knew, SJM400 has different size & structure as sparrow & aplus300. It is new design recently.
SJM400 provide better performance for 3D flying than aplus300

It sure looks cool. Does the recommended battery sound a little weak to anyone else, though?
