My 7 year old boy hoping to have as a helicopter of this type I have studied well before it would get there. And yes it is useless to put in check. There very pleasant surprise: easy handling, extremely strong given the number of crashes before proficiently. 3 days of manipulation to bluff his world, what really fun. Great product! Works with rechargeable batteries unlike the "Special Edition" version with no explanation of the SAV service. Parts available from Silverlit. I also want one now !!!
