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.

 

Review

First I would like to thank everyone again who contributed for the purchase of my Genius CP/Devo 7.
I would like to thank Jason for thinking of doing this for me and thank Michael
for making the Tom Z Genius Review Contribution thread.
I had enough to pay for the Genius CP/Devo 7 in full plus cover shipping.

I will also be converting the heli to BL and will add pictures, video, and information on it.

 

First Impressions:

Helicopter:

My first impression when I saw the Genius is that is looked nice! It is small and light. It is dark and it is going to be hard to see in flight.
I was surprised how much smaller it was compared to my MCPX.

 

Devo 7 Transmitter:

The Devo 7 looks nice also and feels good in my hand.
The sticks feel smooth. The TX is heavy though with the 8 “aa” batteries it runs on.
The menu was a nightmare to work through and took me all day and night to fiqure it out.
Once I fiqured it out I could fly through the menu with no problem.
The LCD screen is text only. The text size is huge, way too big. There are only 5 characters at one time anywhere in the TX menu.
There are no graphs in the Devo 7. There are no graphical curves for throttle or pitch curves. I was dissapointed in this.

The battery life is very good! I have used it most of the day and night and for a while the next day and I still have two bars left.

 

Overview:

I took the heli out of the box and charged the battery. Then put in batteries in the TX.
I binded the heli and took it for a test flight.
The heli was nice and smooth and very stable! The climb out was the same as my stock mCPX IMO.
The heli handles well in turns.
The heli is ultra stable in 6-axis mode! The heli drifts to the left in this mode. You can trim it out in the TX though.
IMO the 6-axis mode will be very good for beginners stepping up to a CP helicopter.
I have had coaxial, fixed pitch, and collective pitch helicopters.
With the stock TX settings there is no expo and D/R is set at 100%. This was too much for me so I had to fly the heli gentle.
Also when switching from normal mode to stunt mode the heli dropped 10 feet or more.
I adjusted the pitch curves, throttle curves, and set expo and D/R. The heli is much better now and there is no dropping
of the heli when I go into stunt mode.
I am working on posting settings for the Devo 7. I will also have a step by step video of the settings.
I also worked on TX settings for the Walkera Genius CP Helicopter WK2801 compatible and posted them in my RX/TX sticky.
There are both 3D Settings and Beginner Settings.
The tail blows out some. The mCPX tail blade is said to hold pretty well so give it a try. This is the V3 tail blade. V1 and V2 are a smaller blade.

These were a throttle hold issue which is now resolved.

 

 

How does it do in a crash?

I just did some flipping and very short inverting.
I flew into my fence inverted hard two times and was flying a tight fast circle
and flew into the brick on my house. No damage to the heli except
one blade tip got scuffed from the brick and the collar slipped loose.
Pretty impressive! Crashes on the grass were nothing at all. Pick the heli back up and fly.
This is good crash tests and this is what people want to know so I
am glad I took a chance with no spare parts. I will try again soon.

There is not enough servo throw to flip over fast enough. Flipping is slow…
I turned off EXP and D/R and it helped a little.
I am going to turn up the servo ext. pot to MAX on the RX and turn up D/R to 125% or more then it will flip much faster.

Genius VS mCPX

  • Genius is lighter than the mCPX.
  • Genius has a square graphite tail boom. Should be pretty strong in a crash. Much stronger then the mCPX boom is what I am thinking.
  • Genius has regular servos which I like better and are half the price of the mCPX servos.
  • Genius has adjustable links to adjust blade tracking. mCPX are fixed so you can’t adjust them.
  • Genius has a 6 axis gyro and should be great for beginners. mCPX has a 3 axis gyro.
  • Genius main gear looks like it won’t twist or slip down on the main shaft like the mCPX.
  • Genius has full gyro adjustments.
  • No frame cutting required on the Genius to make it brushless. mCPX requires extensive frame cutting to fit an outrunner.
  • Does the Genius have better canopy mounts? The mCPX canopy mounts break way too easy and you have to replace the entire frame as they are not replaceable.
  • Most genius replacement parts are much cheaper than the mCPX. I saw a site with most of the Genius spare parts in stock with prices.

Genius head speed: 4,680 RPM

mCPX head speed: 4,380 RPM

Genius weight with battery: 41.9 Grams

mCPX weight with battery: 45.4 Grams

Genius flight time:

  • 3 Minutes: 3.78V
  • 4 Minutes: 3.71V
  • 5 Minutes: 3.68V

mCPX flight time:

  • 4 Minutes: 3.73V
  • 4.5 Minutes: 3.69V
  • 5 Minutes: 3.67V

************************************************** ************************************************** **

Some things I wanted to know:

  • How does it fly out of the box?
  • How stable is the Genius?
  • How responsive is it?
  • How well does the 3 axis and 6 axis gyro work?
  • How is the power and climb out?
  • How are the motors?
  • How well does it flip and roll?
  • How well does it 3D?
  • How is the flight time?
  • What problems or issues does it have if any?
  • How much better is it when I make it Brushless? What is the flight time?
  • I want to see if the Genius handles the wind well like the mCPX does. I fly and shoot my videos in 10-15 MPH winds with my mCPX.
  • And most of all how well does it take a crash! Calling it “Indestructible” is not accurate. I do think it will be very crash resistant and even more than the mCPX. I will find out soon.

Pros:

  • Very strong in a crash for me so far.
  • Flies well stock out of the box.
  • Decent power.
  • Very stable and smooth flying.
  • Square tail boom which should be strong in a crash.
  • Standard servos.
  • Solid main shaft.
  • 3 axis gyro and 6 axis gyro.
  • Gyro adjustment pots and servo ext. pot on the RX.
  • Adjustable links to adjust blade tracking.
  • No frame cutting required to make it brushless.
  • Replacement parts are much cheaper than the mCPX.

Cons:

  • Landing gear bending/breaking easy which is built into the frame. You will have to get a new frame and swap everthing over to it.
    This is not good for a beginner who will be landing hard while learning.
  • Canopy is extremely thin and breaks very easy!!!
  • Gyro issue. Nose drifts to the left. If Walkera fixes this in the firmware a V2 RX will cost $80.
  • Gyro issue in 6 axis mode. Helicopter drifts. If Walkera fixes this in the firmware a V2 RX will cost $80.
  • Canopy pin is extremely loose. It makes taking off and putting on the canopy hard to do. I have had the canopy slide in the way of the swashplate.
  • It is dark and hard to see in flight.

Note:

Yaw problem in hover using 3 axis mode:

What works well for me for the nose drifts to the left in hover is to use subtrim instead of trim to correct the yaw problem.
You can try right sub trim 5-10 % or so. My tail is now holding well with 5.5% subtrim. I have seen people use 32% or higher and even 47%.
I also increased the gyro gain to 87%. With subtrim and more gyro gain the tail will now hold even in hands off hover.

Helicopter drifts in 6 axis mode:
This can be trimmed out as a work around to the problem.

 

Thrust Test: – I need to double check these. The numbers sound to low.

55.5 grams full negitive pitch in stunt mode with the stock battery.
59.2 grams full negitive pitch in stunt mode with the Hyperion 240 mah battery.

 

Head Speed:

4,680 RPM at mid stick 100% throttle with the stock battery.

4,860 RPM at mid stick 100% throttle with the Hyperion 240 mah battery.

 

Flight times: – Stock battery.

  • 3 Minutes: 3.78V
  • 4 Minutes: 3.71V
  • 5 Minutes: 3.68V

158 mah put back into the battery.

 

 

Final thoughts so far:

This is a nice helicopter that is very stable and flies well IMO.
The Devo 7 looks and feels nice. The sticks are nice and smooth.
The menu is not user friendly at all. It took me a long time to figure out how to
program my way through the TX. But now I can fly through the menu and program it fast.
The climb out power is OK for stock and is about the same as the mCPX IMO.

Wakera did a fine job on the helicopter!
They should have done a better job with the TX menu and added graphical curves for throttle or pitch curves.
