Helicopter 4 Channel RTF V4 LAMA 2.4G review and specification

The Lama small Helicopter v3 & v4 models are a balance of engineering sophistication and manufacturing simplicity. The V4 Lama requires a measure of coordination and dexterity to fly it well. Unlike regular fixed pitch or collective pitch model helis, the Lama uses a set of upper and lower counter-rotating blades to maintain heading. It is intended for indoor flight in a large space, or outdoors on a wind-free day. Controls are throttle (up and down), nose heading (left/right steering), side-to-side movement, forward and reverse motion.

You will want extra blades. While the unit comes with 1 set of each lowers and uppers (which is more than can be said for the CX2, as they come with no extras) the standard E-sky blades are very fragile. They "cone" upwards while in the air, which makes blade strikes a real issue. There are 3 real options. The standard replacement blades are fairly cheap compared to the CX2 blades. Or you can purchase some Xtreme blades or helitek-rc hardened white blades, as both are good 3rd party options that are stronger than the stock blades.
Unlike more expensive and technically advanced model helis, you'll find yourself spending more time actually flying & very little time worrying about crashing it - it's that stable in the air.
Unlike more technically advanced helis, the Lama is simple to adjust, and is remarkably durable. Operate it like you would the family car: drive it into a wall or tree & you wiill definitely damage it. Replacement parts are readily available, and cheap. Battery charge time is around 2 hours for a fully drained battery. Flight time is around 15 minutes. This is normal to better than usual for an electric aircraft.
