The T580G is a larger version of the Lotus T380G. The T580 is capable of carrying an extra 200g payload than the T380 so can carry a larger camera, a higher capacity battery for longer flight times and best of all the Lotus PTZ camera mount (more info on that below). The larger size also makes it a little more stable in flight. Inside is the same futuristic technology found in the T380 with advanced GPS positioning and intelligent automatic flight control. The technology found in this drone is usually only found is much more expensive models. GPS automatic position hold, altitude hold, automatic take off and landing and even automatic return to home on signal loss are all found on this model. Check out the full feature list below. This is the ARF version that stands for almost ready to fly. An ARF model has everything still pre-installed, but is missing the battery, receiver and transmitter for customers who already have their own so don't need to buy them again.
