Evolve 300 CX RTF Review

Avoid collisions with this considerable coaxial heli
There are twin things that mount out about a new Evolve 300 CX coaxial helicopter from Innovative Flight Technologies (IFT) — a stretch and innovative on-board Collision Avoidance Technology (CAT). Well, actually, there are other considerable features, though these twin unequivocally squeeze your attention. Loosely styled after a Eurocopter AS350 Ecureuil, a Evolve 300 CX is most bigger than your standard indoor micro coaxial heli and is permitted in Ready-to-Fly (RTF) and Ready-for-Receiver (RFR) versions. The RFR chronicle comes prepared for we to implement a receiver so we can use your possess transmitter. This examination is formed on a RTF chronicle that includes all you’ll need to fly—straight out of a box.


There are twin CAT sensors on a sides of a heli. Remember, we should not supplement any decals or markings that would cover adult a sensors.

Under a nose is another CAT sensor and it looks like a scale hunt light. There is another sensor mounted in a finish of a tail boom.

Flying a Evolve is a block of cake—even within a proportions of a Model Airplane News editorial office! For accurate hovering in really parsimonious spaces, it’s best to switch a CAT complement indication to Low and rest some-more on your piloting skills.

The Evolve 300 CX RTF is a really finish package. It comes with AA batteries for a 5-channel 2.4GHz conductor and a 6-channel receiver (already installed), a gangling set of rotor blades, a 800mAh 3S 11.1V LiPo battery, a sincerely thick instruction primer and a DC balancing horse with an AC adapter. There’s zero else compulsory to get airborne. The factory-installed CAT procedure and ultrasonic sensors and an modernized 3-in-1 control section and 7.5-gram digital sub-micro servos also come commissioned and prepared to go.

The helicopter’s physique is done from stout lightweight molded cosmetic and is connected to a categorical support with screws extrinsic into stretchable tubing trustworthy to a frame. This provides a tiny give to forestall enormous of a physique connection points. The DC horse is easy to use and has twin LED indicators. The horse is powered and prepared to assign when it flashes red. You bond a white balancing connector to a horse and afterwards red and immature will sojourn plain during charge. When it is no longer green, a assign is complete. If it starts flashing red and green, there is a charging fault. The charger’s putout is 0.8A.

In a Air

Before any flight, we contingency spin a conductor on before joining a moody battery to a on-board control unit. The stifle hang and stifle trim spin should be set to a lowest environment for a control section to initialize and arm properly. Switch a conductor on and wait for a transmitter’s red LED indicator to peep fast and afterwards sojourn solidly lit. Place a heli on a flat, spin aspect and bond a moody battery. Wait for a control unit’s LEDs to peep red 3 times and afterwards immature 3 times. It will heat solidly immature to prove it has been scrupulously initialized and armed for flight.


  • Stability: The Evolve 300 CX has glorious fortitude and with a exam model, a mixer/gyro pot adjustments were right on a money. The heli carried off and a nose never drifted off heading. It demonstrated “hands-off” fortitude (with low rates) even when a stifle is modernized or reduced somewhat to control altitude.
  • Control response: Evolve 300 CX has a good feel and it responds simply both during high- and low-rate settings. Because of a fundamental stability, it does take a tiny “push” of a controls to trigger brazen flight. However, it marks simply and we can simply govern figure-8s within a cramped area. Straight out of a box, a rotor blade tracking was nearby ideal and no adjustments were required.
  • CAT System: It was fun to play with a Collision Avoidance Technology complement and we tested it in an area of about 20×20 feet square. we put a Evolve into a float and afterwards usually let it deposit about. As it approached a wall, we could clearly see a complement “nudge” a intermittent control to “push” a heli divided from a wall. we also attempted it with a nose and tail indicating to a wall as good as with a side confronting a obstruction. Every time, a heli was changed to a safer position divided from a wall. Pretty cool!


I also hovered and flew a Evolve outward in ease breeze conditions. we felt that it had copiousness of mass for glorious fortitude should a tiny breeze try to pull it off course. With a CAT complement incited off, we can fly during will and a heli stays really commander permitted for amateur and gifted pilots alike. The instructions do discuss a shorter (optional) stabilizer flybar (IFLH1319X) that we can use to boost a Evolve’s control response. we do not suggest drifting a Evolve in blowing conditions or when there is a breeze above 10mph. There is usually so most control permitted and a breeze can over-power a intermittent controls. In ease conditions, this heli is a blast to fly.

The Hi/Low mode switch for a CAT complement is permitted by an opening in a bottom of a fuselage. Hi responds quicker with a longer operation and Low is for a slower response with a shorter range.

The simply done IFT 5-channel MP5H conductor is 2.4GHz and facilities automatic trim levers, a twin rate switch, and a rigging switch. Four AA batteries are also enclosed for a conductor and there is a digital voltage arrangement during a tip of a conductor case. On a reduce right is a tiny induce cover underneath that is 4 servo reversing switches (for a primary controls) and a rigging name switch for normal/slow.

The rigging switch during a tip left is used to switch a CAT complement on/off and can be activated before and during flight. Flipping a rigging switch so it is indicating divided from we turns a CAT complement off. The twin rate switch (top right) controls a settings for both aileron and conveyor control.


The Ready to Fly chronicle comes with all indispensable to fly including a 2.4GHz transmitter. Not shown here are a LiPo battery pack, charger, and gangling rotor blades.


This is a initial RC helicopter we have flown that has this feature. Using ultrasonic sensors and modernized software, a IFT-exclusive Collision Avoidance Technology (CAT) automatically commands a 300 CX to equivocate collisions with walls and furniture. There are 4 sensors with one during a front, back, and any side of a helicopter. The sensors measures a stretch to an intent so a control complement can request inputs to equivocate a collision. According to a instructions, a complement generates sound waves in a 40KHz operation and it suggests not drifting a helicopter around pets and dogs who might be uneasy by a high-frequency sound. This is a good underline to assistance a first-time commander drifting in smaller indoor spaces to forestall crashes and damage. It is also not endorsed to fly by doors or other slight areas with a CAT complement incited on.

The Evolve 300 CX is versed with a 3-in-1 control section that combines a functions of twin ESCs, a mixer, and a gyro. The section also has gyro benefit and mixer composition pots. These are set during a bureau and should not need adjustments. If, however, we find that a nose of a heli constantly wants to spin in one instruction or a other, we can mislay a section and make a automatic adjustment. The instructions explain a routine in detail.


The Flying Squirrel

Eurocopter AS350 Ecureuil (Squirrel) is a single-engined light helicopter creatively made by Aérospatiale, (now partial of Eurocopter). Developed in a 1970s to reinstate a Aérospatiale Alouette II, a AS350 went into use in 1975. The Ecureuil has turn intensely renouned in both Europe and a United States as a rescue helicopter. Several versions including a twin-engine chronicle can be seen behaving military, firefighting, and EMT “Life Star” collision studious depletion roles. An Ecureuil AS350B3 was used to set rotorcraft universe records, for tip of both alighting and take-off. On May 14, 2005, commander Didier Delsalle landed his Ecureuil during an altitude of 8,848 meters (28,756 ft.) on a tip of a Mount Everest. The Fédération Aéronautique Internationale (FAI) compulsory a aircraft remained on a limit for longer than twin mins before returning to Lukla. Didier indeed landed on a limit twice and stayed during a limit for about 4 mins twice.
