RE: Rhino 4900
Nickolay, Ihave a Vanquish with 2 5S Rhino 4900s, a Turnigy 1000 2S pack for radio that I've connected with HD JRplugs and a DigiSwitch. The whole aircraft ready to fly is just under 5Kg so no prob. Ican fly a UKMasters schedule using less than 70%of the pack capacity. I can do 6 flights with the Rx battery and it is only uses around 25% capacity. I'm using an AXi 5330/F3a motor and never need to use full power until the very end of the flight. Hope that helps.
