Walkera CB100 Helicopter Review
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.
First I would like I would like to thank dkfuji (Darryl), GITech (Jay), and everyone else who has helped me out!
Just got my CB100 today. Took it out of the box, read the manuals, binded the helicopter with the transmitter, put in the battery and tried it out. The motors engaged about 25 % throttle as the LCD screen showed. Lifted off for the first time. Was able to hover it pretty good. This does hover just like a coaxial helicopter for sure. It is very stable. Once I trimmed it out I flew it hands free for a good amount of time. This helicopter is quiet. Much much quieter than my Blade CX2 even with Xtreme 180 SE motors.
I was able to fly the helicopter similar to my CX2 almost right away. It really whips around in turns. I flew a circle and it whipped around fast on me and almost lost control. Wasn’t giving it much stick at all either. Glad I didn’t move the servo holes out yet. Also will add the tail holds very well.
Took it outside also. Winds were 13 mph but I have an enclosed fence which blocks out some of the wind. It had no trouble with some good amount of wind. I just tilted the nose down and it pulled itself through the wind good. I fly in wind a lot so I’m used to it.
Here is a review on the Novus FP which is a rebranded Walkera 4#3.
They flew it in 5-7 mph winds and didn’t have any problems so that’s
probably in the range of the wind I was flying in as the fence blocked out a good amount of it.
Have the battery charging now and will take it back outside when the wind calms down.
I will post some video flying inside and outside when I get some practice with the new heli. Have to get used to the fast response and quick turning it can do.
It’s different than my coaxial as you have to fly the tail.
Still for me as you may have seen my posts this helicopter is a a little too stable and I want to decrease the self stabilizing system by trying lighter flybar weights, shorter flybar, and flybar paddles from the 4#3B.
Also I will move the balls on the servo arms out to the 3rd hole, move the mix arm balls to the inner holes.
The more I have to fly the heli, the more it will help me fly my T-Rex 450 SE V2.
It sure is great out of the box to just fly around indoors without having to constantly correct it.
I recommend this helicopter if you are looking for a super stable helicopter that flys similar to a coaxial. I would think if you can fly a coaxial you will have no problem with this.
It is a little different than a coaxial, you have to fly the tail. I went from taking it out of the box to flying it pretty well in half a battery pack.
Just got back from flying this outside. This helicopter is a BLAST!!!
I got it going pretty fast whipping all around the yard but still didn’t have it a close to full throttle yet.
Flew forwards, backwards, circles, hovered nose in, tail in, sideways and more.
Flew it waaaay above our two story house. Got the turning down pretty good this time. I have to get video of this soon!
WK-2402 4 Channel 2.4 GHz Transmitter.
I have to say the TX heavy! It has 8 AA batteries. The LCD screen is nice, big, easy to read, and really lights up bright.
I don’t like the digital trims on the LCD. The trim readout only moves 1 time for about every 11 clicks of the trim.
Not like say the DX6I which the readout moves with every click.
It does have a percent readout though that does change with every click so at least it’s something.
This isn’t a big deal as when you are flying you just click the trims anyway.
Looking down at the LCD screen and trying to read the trim icons could distract you and make you crash.
I have come close a number of times doing this…
On the digital trim when the trim is centered the icon is in the middle, when you click the trim 11 times the icon moves over one time.
Then you click the trim 20 more times and the trim icon moves one final time. So it’s center, moves over on time, moves over one final time.
The TX doesn’t have any programming like expo, gyro gain, servo travel, etc.
It does have servo reverse settings, stick mode settings (4 of them) and buzz.
The heli is tuff so far. I have hit the wall hard two times zero damage.
Just put a small mark in one main blade.
Then crashed outside going too fast and loosing control a couple times.
Only damage the one time was I bent the tail rotor blade posts
and blade itself. I hit the ground hard. Thought it was going to be in pieces.
I put on a new blade on and went back to flying and filming. Tough little heli!
I am getting very good flight times. I think it will get the flight time of 9 to 10 minutes as advertised. I will time some flights soon.
Problems or Issues
The stock battery has gone bad. It only had 10 flights on it.
It wasn’t puffed or damaged.
One minor issue with the RX casing coming loose.
Took it out of the box and flew it.
No adjustments needed. Gyro was adjusted spot on and holds well.
All screws were tight. Blade tracking was perfect. Can get the CG perfect.
The heli is VERY crash resistant!
The worse I have done is break one tail rotor.
Walkera did a fine job with this helicopter!
1. Make sure the pins on the tail blades are in the motor holes (the small ones)
and make sure the tail blade isn’t cracked or bent.
2. Check to make sure your tail boom doesn’t have a crack in it.
3. Check your gear mesh.
Q: About how much less flight time will I get with the 14T and the 16T compared to the stock 12T
A: You will still get around the same flight times because there is little load on the motor to fly this heli.
On 14t & 16t you should still get over 6mins of flight time.
Q: What are the dkfuji mods?
A: Installed 4.5g outrunner w/19t plastic gear
Installed 2605A Rx and set all servos to 120% Travel
Moved servo arm balls to the 3rd hole
Moved mixer arm ball to inner hole
Installed 4#3b tail rotor blade
400mah 20c Oversky lipos
Lighter flybar weights and moved in
Q: What are the differences between the CB100 and 4#3B?
A: Rotor Head Set
Flybar and weights (paddles on the 4#3B)
Frame and servo holder
* Blade Holders are the same on both helicopters
* Main Rotor Blades and Tail Rotor blades are the same on both helicopters
* Skid Landing Gear Set are the same on both helicopters
* Tail Boom are the same on both helicopters
* Main Gear are the same on both helicopters
* Tail Motor Holder Fin Set
Q: I noticed my CB100 swashplate has a slight tilt to the right (when viewing from behind).
A: That’s normal
Mixing arm ball positions on the CB100 – Thanks altronpower and everyone else who helped answer this for us!
Moving the ball to the inner hole will increase stabilization (flybar ratio INCREASES) – The cb100 will be less responsive.
Moving the ball to the outer hole will decrease stabilization (flybar ratio DECREASES) – The cb100 will be more responsive.
AILE to left/right servo
ELEV to up/down servo
PIT not used
RUDD not used
TAIL MOT SIG to tail ESC
MAIN MOT SIG not used
You MUST put the MIX pot on the 4in1 to MAX.
Then if needed go into the subtrim in your RX – SUBTRIM RUDD and turn it up to
where you need it until the tail holds straight. I have mine at R 21.
The power cable on the 4in1 that goes to the battery is not used in this setup.
I took mine off to save weight and clutter.

Here are YouTube Videos.
Just measured my yard. It is 65 x 65 feet. My yard looks small in the videos.
The camera doesn’t really capture how fast it is going just sitting on a
bar stool like I have it.
