With absolutely no disrespect intended ETC, I'm wondering how you can possibly give Ripper an estimate on the cost of repairs to his P4 Pro when you have no idea of the extent of the damage? You haven't examined the craft, and you don't know if the camera has any internal damage, or if there's any internal damage to the Quad itself.
Sorry, ETC, but I think your guess of "probably less than $20." is a bit irresponsible and gives Ripper false hope for his repair costs.

Perhaps you never crashed and have never repaired any of these copters. I can see by the photo the arm is bent - under $20 and an easy repair. Worst case would be a ribbon add another $30
Anyone who has had multiple crafts and multiple crashed knows what it take to get them back into shape. No disrespect.
