All of this plus flashing LED searchlights and factory-applied decals are included.

    The Estes Mini Helicopters come Ready-To-Fly with everything you need in the box except six AA Alkaline batteries. The R73-OPS Attack Helicopter has a military green finish and decals that give it a rugged look. The SF-161 Helicopter comes in a red and white scheme.

    The infrared transmitter has a band selector switch that should be set to either A or B to match the letter on the bottom of the heli. This allows several helis to fly together. Spare blades and a tail rotor are included but I have not needed them even after considerable abuse of the heli. The model is quite rugged! A multi-language manual is included with excellent photos and setup instructions.

    Charging:

    The transmitter requires six 1.5V AA Alkaline Batteries (not included) to be installed before you can charge the model. The hatch is held in place by a small screw. The charging cord is stored in the rear left handle of the transmitter. A hidden latch simply slides down for access to the chamber. Once the batteries are installed, the Power and Charge indicator just below the band selector on the front of the transmitter will light green when turned on. When the batteries get low, this indicator will flash red, indicating it is time for a new set of batteries.

     

    With the transmitter on, plug the charge cord into the helicopter. The controllers green LED will change to red, indicating the heli is being charged. Note that the connector will only fit one way into the heli.

    The helicopter can fly for 4-5 minutes after 30-40 minutes of charging. Charging is complete when the LED turns green again. Remove the charge cord, store it back into the transmitter handle, and you are ready to fly!


    After charging my heli, I turned the transmitter back on first and then set the On/Off switch on the heli to On. When I throttled up, the heli lifted off the ground nicely to a few feet. The counter-rotating blades provided very stable flight. I then used the trim knob on the front of the transmitter to eliminate the slow rotation and was off on my first indoor adventure around the house!

    I was happy with the ruggedness of the heli. After banging it into several objects, there was no damage even after it hit the tiled floor. I showed the heli's versatility in the video by flying in small areas and the infrared link between the transmitter and the heli was tested in a wide range of light sources. The only times I had problems was in bright florescent lights and outdoors. The heli simply stops when it encounters interference. Otherwise, the infrared link worked quite well.

    The flights were about 5 minutes long and the heli would not lift up more than a few inches once the battery was drained. The charging system appears to use a diode in-line with the connector on the heli, preventing use of a standard Lithium charger from recharging the model. I have recharged the heli about 10 times from the transmitter and the batteries are still going strong. Only the charge time increased.

    The Estes Micro EP Helicopters seem to be a great low-cost model for beginners that have never flown a heli before. Designed for entry-level flyers 14 years and older, it is easy to fly, safe, and difficult to damage. Further, the model is Ready-To-Fly (RTF) right out of the box and requires no assembly. I suspect that pilots younger than 14 will also enjoy this low-cost flying model as it is much more than just a toy!
