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.

  • 2 Minutes: 3.91V
  • 3 Minutes: 3.81V

  • 5 Minutes: 3.70V

Flight Time: – Turbo Ace Linear Battery 650mAh 25C – Turbo Ace 915 Motor w/9T – XP-15A-2 ESC

  • 2 Minutes: 3.82V
  • 3 Minutes: 3.71V
  • 4 Minutes: 3.68V – Power got very low at 3:45 and I had to land.

The heli has powerful pitch pumps and climb out and the motor doesn’t bog.
I am using 70% L/H Pitch Travel Adjustment.
This motor is pretty loud! It draws a lot of power. The motor and ESC run very warm but not hot. The battery is also warm.
I don’t recommend this motor for a beginner as it has a lot of power which will cause more damage in a crash.

KBDD Blade Review

 

Weights:

  • Stock Blade: 4.5G
  • KBDD Blade: 3.5G

 

Head Speed: – Stock Fullriver 600mAH 20C Battery – XP-15A-2 ESC

  • Stock Blade: 4,830 RPM at mid stick 100% throttle with the stock battery.
  • KBDD Blade: 4,800 RPM at mid stick 100% throttle with the stock battery.

 

The KBDD Blades were balanced perfect out of the package. The blade tracking was perfect.
The heli response was quicker for sure with the KBDD blades.
I flew mine in no wind so I can’t comment on how they do in wind yet.
Also I will try flipping and inverting when I get a chance.

 

“Originally Posted by IntegrityHndywrk”
The 130X main blades really completed the performance with the heli.
But those light blades do not play well with the gyros, especially in wind/gusts.
