I placed an order for a $20.00 "explorer" kit (86635) at 1am and within two hours I changed my order to the all in one "ft explorer get started package" $190.44 with a $5.00 upgrade on the power pack from "B" to " C" and the authorization to charge my Amazon account on file the increase on the charge. I received the $20.00 airplane kit and nothing else. I have sent two emails asking for an update on the upgrade to my order with no response. Finally I received an email the content "your order has been received" and nothing else. I have requested a phone number for customer service with no reply and I requested customer service call me with no reply. As of today I would not recommend a purchase from Flitetest Test to anyone!
