Hirobo’s Lepton EX kit is the first in a series of true mid-size electric helicopters. Designed for outdoor flight, it can also be flown indoors in a gymnasium environment. Capable of 3D maneuvers, it sports a 37” rotor diameter and a 33” length. The Lepton’s dimensions help it deliver dependable as well as aggressive performance. It has been engineered to handle the rigors of 3D aerobatics.
The Lepton draws on the World Championship engineering of Hirobo’s Sceadu Evo, Freya and Eagle. For instance, the design of the aluminum rotor head, mixing and stabilizer control arms are Evo inspired, as is the Direct Tail Drive system for driven tail aerobatic autos. What’s more, parts normally optional with other mid-size helis come standard, including carbon fiber, single piece frame plates, a CCPM 120 degree control system, aluminum swashplate, tail case and more.

Both XRB minis provide the opportunity to fly mini choppers indoors, at home, in any weather. Learn, train or practice, they will both do just about any maneuver a full-size RC chopper will do, including hovering, reverse flight, pirouettes, fly backward, side-to-side, funnels and more. Both are 14.04" long; 3.51" wide; 13.65" rotor dia; 7 oz . Both feature counter rotating blade (XRB) engineering that is proven to provide the rock solid stability needed for close quarters, indoor flying.
The Sky Robo is tether-free RC. This radio control mini features a 4-channel helicopter transmitter, receiver and two servos, 720 mAh Lithium polymer battery and wall charger... and delivers a 15 minute flight on a full charge.
The Mini Lama's power and control signals are fed through 12 ft tether. It’s complete with two stick, 4 channel, remote control system and a power source that plugs into the wall for a constant power supply allowing you to fly without pause, as long as you like no batteries, no charging.
