We recieved a defective apache helicopter. worked with Xheli customer service to get it going. Recieved replacement battery and replacement controller. Nothing worked. Returned everything to them in Nov 2008. Got confirmation of return receipt. Phoned and emailed Xheli several times. Each time they claim the refund will show up within 10 business days. It never does. It is now March 2009. All hope is lost. Xheli is an unreputable company and is not to be trusted.
