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

The Mini CP is awesome with the brushless motor!
It is light weight, powerful, provides great climb out, and has good flight times.
I will not use be using the brush motor again.
Still would like to test the Genius CP brush motor and the mCPX brush motor. Have both these motors but need a pinion for them.

 

Flight time:– C05 motor w/9T pinion and the Genius CP main gear. Stock Genius CP battery.

  • 30 seconds: 4.04V – Power got very weak at about 15 seconds. I had to land.

Flight time: – C05 motor w/9T pinion and the Genius CP main gear. Hyperion 240 mah 25C battery.

  • 1 Minute: 3.98V
  • 2 Minutes: 3.84V
  • 3 Minutes: 3.76V
  • 3:30 Minutes: 3.72V – Power got very low and I had to land.

Flight time: – C05 motor w/9T pinion and the Genius CP main gear. Turnigy Nano-tech 300mAh 35C battery.

Note: These are using brand new batteries on their first charge. I expect the power and head speed to stay stronger for these times
and maybe even get more flight time. I will update these when I get several charges on the batteries.

  • 2 Minutes: 3.87V
  • 3 Minutes: 3.78V
  • 4 Minutes: 3.73V – Head speed is slowing down approaching 4 minutes.
  • 5 Minutes: 3.69V – Head speed is really slowing down. Too much unless you just want to hover with low head speed.

Flight time: – C05 motor w/9T pinion and the Genius CP main gear. Oversky 400mah linear 20C battery.

  • 2 Minutes: 3.91V
  • 3 Minutes: 3.85V
  • 4 Minutes: 3.78V
  • 5 Minutes: 3.74V – Power got weak at 4:40 minutes.

 

Thrust Test: – C05 motor w/9T pinion and the Genius CP main gear.

  • 53.5 grams full negative pitch in stunt mode with the stock Genius CP battery..
  • 98.5 grams full negative pitch in stunt mode with the Hyperion 240 mah 25C battery.
  • 101.5 grams full negative pitch in stunt mode with the Turnigy Nano-tech 300mAh 35C battery.

 

Head Speed: – C05 motor w/9T pinion and the Genius CP main gear.

  • 5,220 RPM at mid stick 100% throttle with the stock Genius CP battery.
  • 5,670 RPM at mid stick 100% throttle with the Hyperion 240 mah 25C battery.
  • 5,730 RPM at mid stick 100% throttle with the Turnigy Nano-tech 300mAh 35C battery.

 

Telemetry:

I have found out that using the telemetry eats up the battery time.
I went from 5 full minutes of flight time on my Master CP with telemetry
inhibited in the TX to 1:25 minutes flight time with the telemetry enabled.
I found the same thing with my Mini CP, 1:25 minutes flight time with the telemetry enabled
and 3 minutes flight time with the telemetry inhibited.
My friends Mini CP had the same results as I did with telemetry inhibited and enabled.

Devo 10

I set the Sensor Setting – Voltage – External: V1- Alarm Voltage to 3.5V. This give me 3.72V per cell no load which is pretty good.

 

Weights:

  • AUW = 43.3 Grams with the stock Genius CP battery.
  • AUW = 45.1 Grams with Hyperion 240 mah 25C battery.
  • WK-WST-10A-LT (ESC/Converter): 3.3G
  • C05 brushless motor: 4.6G
  • Hyperion 240 mah 25C battery: 7.7G
  • Turnigy Nano-tech 300mAh 35C battery: 7.9G
  • Oversky 400mah linear 20C battery: 11.2G

 

 

 

Devo 7 TX

To get 85% throttle on the C05 motor measured with my tach I had to set the throttle to 39%.
Setting the throttle to 85% will not get you 85% actual motor speed but 39% does.

To get 90% throttle on the C05 motor measured with my tach I had to set the throttle to 50%.
Setting the throttle to 90% will not get you 90% actual motor speed but 50% does.

To get 95% throttle on the C05 motor measured with my tach I had to set the throttle to 75%.
Setting the throttle to 95% will not get you 95% actual motor speed but 75% does.

Here is a video of me flipping my Mini CP BL for the first time.
I will have someone film me for the next video I make.

Parts needed for brushless conversion:

1. WK-WST-10A-LT (ESC/Converter)

* You want the version with a single white signal wire. The other verson has a 3 wire signal wire and you don’t want that version. See picture.

2. C05 motor

3. M0.5 pinion

4. Another Option: Oversky 7A PnP Brushless ESC for Genius CP/Mini CP

 

 

Pinions: – You can also remove and use the pinion on the Genius CP or Mini CP motor like I did.

C05 Motor: – 1mm motor shaft. This is the same motor being used for the Genius CP and Mini CP brushless .

Here is more information from Manuel (buildem336). These are from his posts here on Rcgroups.

C05 with 8T pinion and stock Main gear is 5300 HS
C05 with 8T pinion and Genius Main gear is 5000HS (same as stock)

I got a chance to tach it today with the Genius main gear and MCP stock 8t pinion and it came in at 5,000 HS.

I tached the stock genius motor with the Genius main gear and with the Mini Cp main gear and here is the results.

Genius main gear 4710 HS
Mini Cp main gear 4920 HS

9t with a stock main gear will be around 5700HS depending on how good your packs are.

If you want to keep the stock main gear then go with a 7t pinion and that should put you at about the same rpm as a stock Mini Cp.

The C05 motor with the Genius main gear and 8t pinion delivers the same power as stock but with more flight.
I’m getting a minute more in 3d flight. A C05 with a bigger pinion will make it feel more powerful because of the increase of head speed
and will still give more flight time than the stock motor.

DK tried using the Genius main gear and Genius 9t pinion and that came in at 5,300 HS.

Stock heli brushed motor 4,880
Stock Mini Cp with 9t on CO5 5,700
Genius main and 9t pinion on CO5 5,300
Genius main with Mini 8t pinion on CO5 4,750
