TEST: Esky F150X (180mm Helicopter, CC3D, 35.5g)

null

INTRODUCTION

After the introduction of the Esky 150X, probably one of the first cheap brushed flybarless microhelicopter offering a 6-axis stabilization like quadcopters, here is the Esky F150X, the airwolf declinaison. We will find the same ingredients: CC3D board for the 6-axis stabilization, flybarless system, 8mmx20mm main rotor coreless motor & 6mmx15mm tail coreless motor.

BOX CONTENT

null

+ 1 x Esky F150X (with a 1S 150mAh LiPo with 1.25mm microJST connector)
+ 1 x Transmitter (using 4xAA batteries not included)
+ 1 x USB charger
+ 2 x Spare props
+ 1 x Screwdriver
+ 3 x Spare EM tape
+ 1 x Instruction manual (English/chinese)

OVERVIEW

In term of design, no external change with the former Esky F150: we have a full plastic based struture whithout any carbon element immitating the famous airwolf helicopter. The plastic canopy is very flexible and thin; assembled in two parts. IMHO, the structure will present some cracks in the plastic after hard crash session. The F150X seems less solid than the E150X comparatively. The F150X is also a 180mm machine, so clearly targetting indoors applications.

Through the transparent Windows, we can guess the two ports. the left one to plug a microJST PH 1.0mm for USB connexion and the right to connect the LiPo.

The flybar system with two latteral rods

null

Two latteral screws/clips system to lock the structure and attache the front canopy part hidding the LiPo & FC.

null

The tail motor is a 6mmx15mm coreless model. No RPM mention.

-BOTTOM VIEW
As said previously, the canopy is based on two parts assembled centrally and potentially vulnarable after a crash.

null

Fake wheels are simply glued and will pop off relatively fast after minor crashes.

-WEIGHT
A little bit more than 30g without probably.

null

35.1g with the battery installed.

null

Motors & props

The main rotor motor is 8mmx20mm model while the two servos are 4mm.

null

null

null

LiPo

A simple 1S 150mAh LiPo with 1.25microJST connector. No discharge rate mentioned but the battery is strong enough to provide 4min30-5min of flight time.

Disassembling

The green light blinks fast during the binding procedure and as soon as the link is solid, the blue light become solid. Mid-flight, both lights are blinking slowly.

The left shows a 1.25mm microJST port where you will have to connect the battery

On the right side of the CC3D board, a 4 pins port for USB connexion

According to OiOi’s posts for the E150X:

https://www.rcgroups.com/forums/showpost.php?p=36349425&postcount=242

we have the following pinout for the microUSB port. Plug it by disconnecting first the LiPo.

null

Transmitter

The same basic radio chassis as for the 150, 150X, F150. The left shoulder selects beginner & Advanced rates.

null

The right yaw trims engages the binding procedure if your need to relunch the procedure or bind the F150X with a former ESKY radio.
Important, you will need first to arm the machine (lower-right position for mode 2) to take off.

null

4xAA batteries are required. Ni-Mh are working.

null

Good news, the Esky150 protocol in deviationTX have been recently fixed and now no problem to bind the machine.

UNBOXING, ANALYSIS AND DEMO FLIGHT

It’s clear thanks to the the 6 axis stabilisation fly a flybarless machine is super easy… and very smooth. Controls are precize and you can even fly in super tiny spaces. In the other hand, I am not impressed by the power lift of the machine, the ascent rate is slow .and generally the F150X is not a super fast helicopter. More the machine can handle only a moderate Wind. No miracle with a 35g machine. Flight times are good for a 150mah model, between 4min30 and 5min in practice.

CONCLUSIONS

The Esky F150X represents a good indoors microheli wel adapted for beginners with its stability largely improved via the 6-axis stablization.
Be aware, the full plastic structure don’t represent a sign of durability and the machine can’t really flight even a moderate breeze.

PROS

+ Super stable flybarless machine
+ Precize controls
+ Indoors flyer
+ 4min30 of flight time
+ CC3D FC
+ DeviationTX compatible

CONS

– Not wind resistant
– Poor ascent rate
– Fragile plastic structure
