TEST: ESKY 150X, the first CC3D 150mm helicopter

null

INTRODUCTION

Here is the new revision of the Esky 150mm flybarless helicopter. Now it includes a CC3D board for a better stablization and by consequence more easy to fly and more adapted for beginners.
This new generation of helicopter becomes super easy to fly almost as a quadcopter can be.

OVERVIEW

Any real difference can be done between the original Esky 150 with the X revision. A compact 150mm flybarless helicopter with brushed motors
A plastic canopy is protecting all the electronic and the battery bay. The canopy is cliped via two latteral O-rings

A 2mm carbon boon as tail. The vertical stabilizer is strong. No visible tiny switch to power up the system… You need to directly connect the battery.

null

33.2g for total weight. Thanks to flybarless system, some grams are saved… a positive for the flight duration

null

Motors

The main motors is a 8.5mx20mm type

null

For the tail motor, we have a 6mmx12mm corless motors

null

LiPo

A compact 150mAh Lipo ending with micro-JST SH connector. The same of battery we can find for WLtoys V911 for example.

Disassembling

Unclips the two latteral O-rings to open the Esky 150X. Each time you want to power the machine, you will have to remove the canopy. The plastic is so thin that after few assembling/disassembling,
the pastic will crack especially at the lower section.

The battery mount welcomes a pre-installed double side tape. No doubt a larger battery model can be easily installed, a 250mah certainly without disturbing too much the CoG.

null

Two mini linear servos controls the swash. Ball bearings are installed on each side of the cyclic system. It’s a good point.

null

null

A compact serial port is here. I tried with two USB to serial device but not successful connexion to OpenPilot. The CC3D board have probably a proprietary firmware
so no real possitility to tune some settings.

null

UNBOXING & QUICK TESTING

In beginner rate, the machine is super docile with a slow yaw rate. It’s super easy to control the machine and no shifting while yawing. The CC3D board job is efficient. The machine don’t offer
great ascend rate. In expert mode, rates for all 3-axis are largely increased and more adapted for outdoors flights

CONCLUSIONS

This Esky 150x is probably the most stable flybarless Helicopter thanks to its CC3D board. The machine is more adapted for indoors flights but can handle moderate breezes.
What’s a pity, the battery insertion/connexion requieres each time to remove the canopy.

PROS

+ More than 5min of flight time
+ Super stable machine
+ 2 well tuned flight modes
+ Flybarless
+ Same radio protocol than former Esky model

CONS

– No power switch
– Need to remove canopy to insert/remove the battery
– No connexion with OpenPilot software
