I tried a couple of years ago, but the heli I bought started dying immediately after taking it off the charger... had to return it.
I do have another little one coming in for my 2.5 year old though. LOL She loved making mine bounce all around... it was $10 bucks and I needed to fluff up the cart for free shipping. LOL
I picked myself up a little micro rc car for sh!ts and giggles.
