E-flite Blade CX3 Helicopter
Author: Bill Cousins

The E-Flite Blade CX3 is a coaxal heli, main rotor diameter is 13.6in. and has 180 size motors. The overall weight with the battery is 8.0oz. The RTF {Ready to Fly} comes with the CX3 heli, LP5DSM transmitter plus batteries, an E-flite 2-3 cell 7.4-11.1v Li-Po balancing charger, plus one 7.4v 800 MAH 2 cell battery pack. The BNF (bind and fly) comes with the heli. The balancing charger and one 11.1v battery less transmitter.

The BNF model will bind to the following transmitters, E-flite LP5DSM, HP6DSM, JRX9303 2.4, E-flite MLP4DSM, Spektrum DX5E, DX6I, DX7, Spektrum modules and JR12X 2.4. The CX3 also has a heading lock gyro built into the heli which makes the tail very stable. You can also purchase a light kit, comes with 3 flashing lights and a spot light. The coaxle heli has good power but outside in a wind with the 180 size motors does not have enough power to buck a wind. But calm it flys good.

You can also purchase an optonal main motor heat sinks which I highly recommend you install if you do alot of flying. The heat sinks take away some of the heat away from the motors when flying.

There is also optional aluminum parts that can be purchased which includes a swashplate, lower rotor head set, and a bearing holder with bearing. With this installed the controls are a little more precise. Also I highly recommend after one flight that you cool the motors in the CX3 to ambient temperature before the next flite, also do not charge the battery until it is also at ambient temperature, they both will last longer. Do not charge any Li-Po battery inside the house because they can explode and or catch fire. Charge them outside in a Li-Po safe bag, purchased from a hobby store. This is just a precaution.

If balanced and trimmed out properly you should have as much fun as I do with it. It should be treated as a machine and not a toy, and if this is your first or second heli I recommend you purchase a training gear set for it before your first flight. This will make it more stable and if you touch the wall the little yellow balls on the end will hit first and save the blades. If flying in the house make sure you have enough room for it, and make sure small children and your pets are in another room, and also keep it a good distance away from your body and face.

On a hard landing, the landing gear seems a little weak so I added two plastic cross braces on it. These cross braces added extra strength to it also kept them from spreading outwards. All I did was drill two holes in the plastic braces, one on each end and pushed them on the studs on the landing gear and added small O rings to hold them in place.

Read the manual two to three times so you don't miss anything before you fly and fly lots. Have fun and I also recommend you purchase an extra battery as they take about an hour to charge.
