RC Pro Review by: Tom Zadar
Transmitter Setup Guide
See my Transmitter Setup Guides for transmitter setup. The setup guides have all of the transmitter settings needed to make a model completely from scratch.
The Tx Setup Guides have different difficulty settings depending on which setup guide you choose. For Helicopters there are Standard Settings, Beginner Settings, 3D Settings. For Quads there are Standard Settings, Beginner Settings, 3D mode settings.
Each setup guide includes everything needed for setup including Model Type, Swash Type, Servo Reverse, Travel Adjustment, Gyro Gain, Throttle Curves, Throttle Hold, Pitch Curves, Pitch Curve/Throttle Hold, Subtrim, MIX, Switch Assignments, Dual Rate and Expo.
I added a bonus to every setup guide with a Dual Rate and EXPO settings guide I made for Helicopters and Quads.
I am now recommending not to buy the quad unless Walkera fixes the ESC shorting problem. See the Con’s section below for information.
Wow, this is huge!
I thought my Hoten X was big but this is much bigger and heavier.
The quad looks nice and feels like it is built well.
The landing gear seems to be strong and can flex. The canopy feels strong and so do the motor booms and blades.
I like the aluminum case. It looks nice and it is strong. It open and shuts well. It is packed well with thick foam. It will carry everything securely.
This is my first aluminum case that I have ever had. I usually transport my heli or quad in the box it came in or in a plastic tool box.
This is a quad with brushless motors and operates on a 11.1V 2,220 mAh Li-Po battery. The payload capacity is 300~400 Grams.
It has a 6-Axis gyro that can be changed in flight for normal flight mode and 3D flight mode using the FMOD switch or some other switches or knobs like the MIX switch or AUX knob.
It can do 3D rolls and flips when in 3D flight mode.
The quad has a two bright LED lights in the front and one bright dual color LED in the tail. When the LED is Red the quad is in normal flight mode. When the LED is Blue the quad is in 3D flight mode for rolls and flips.
The two orange props and orange motor booms are big and bright. You can see them from a good distance away which helps you with orientation.
The first flight went well. I lifted off and hovered it around for a bit to see how it handles and how stable it is. It was very stable and the response was good.
The power and clim out is decent for a quad this big and heavy.
The quad was not as loud as I thought it would be. I was expecting it to be much louder than my Hoten X.
The second flight I used my Devo 10 in helicopter mode and flew it in normal mode and 3D mode.
It was 30*, 18 MPH wind, and snowing when I made the outdoor videos. The quad had no problems with the cold weather or wind.

LED Light Kit:
The lights look awesome! They are very bright. The lights also light up the landing skids due to they are clear plastic and are so close to the lights.
The lights help you see the quad from a far distance and help you with the orientation.
The lights are easy to install. There is a wire coming off the Rx to power the LED’s. Plug in the LED strips and attach them where you want.
There is an optional light flashing board to flash the lights. I have one on the way and will make a night video with it.
