Helicopter FBL template Version:V0.75
(0 votes)

Hi, just wanting to share my Heli template for FBL helicopters.


Originally its the file from http://open-txu.org/home/special-interests/helicopter/opentx-helicopter-flight-modes/ but with some modifications.


Basic infomation:


Channel Output: Ch1 throttle, Ch2 Aileron, Ch3 Elevator, Ch4 Rud, Ch5 Pitch, Ch6 Gyro. (Fits Dsm2/Dsmx)

All are -100 to +100 in travel and none of them are reversed.


Both "internal radio system" and "External Radio Module" is off, turn on whichever your going to use.


4 "Flight modes", FM0 Throttle Hold, FM1 Normal mode, FM2 Idleup1, FM3 Idleup2.

Each has each own Pitch and Throttle curve. 

Expo and Travel rate limit is shared by Switch G. Expo are adjusted in "Flight mode 0 hold" and Travel rate limit is adjusted in the "Mixer" tab

Gyro are adjusted in the "Input" tab.

Timer 1 that starts on throttle (For battery timer Default 3m and 30s)

Timer 2 that starts on throttle (For total flight time)




SF↑ Throttle Release

SF↓ Throttle Hold



SE↑ Flight mode Normal

SE- Flight mode Idle up 1

SE↓ Flight mode Idle up 2


SG↑ High rates

SG- Middle rates

Sg↓ Low rates


SB↑ Gyro setting 1 - Default 70%

SB- Gyro setting 2 - Default 75%

SB↓ Gyro setting 3 - Default 80%


Gyro setting adjustable in Inputs tab.


SH↓ Reset Timer 1



Curve 1 Throttle normal mode - Default -100 to -20 to 20 to 60 to 100

Curve 2 Throttle idle up 1 - Default Flat 70%

Curve 3 Throttle idle up 2 - Default Flat 100%


Curve 10 Throttle Hold - Default flat -100%

Curve 20 Pitch Hold - Default Linear -100% to 100%


Curve 11 Pitch Normal - Default -40% to 0% to 100%

Curve 12 Pitch Idle up1 - Default Linear -100% to 100%

Curve 13 Pitch Idle up2 - Default Linear -100% to 100%


Also it has an function I call "Throttle lock".

What it does:

1. Locks the throttle to -100 if throttle is not zero when releasing throttle hold. This prevents mistakes to be made if one forgets the throttle stick up or in idle up mode.


2. If throttle hold is pressed but released before 10 second it will not lock the throttle. (In case of throttle hold is applied in the air and you want to regain throttle control).


3. If throttle is zero for more than 15 seconds and throttle hold is not applied, it will auto throttle lock and it will requirre throttle hold switch cycle before giving throttle again. (Inactivity safety if forgotten to put on throttle hold.)


PS: Dont use the stock configuration with long auto training, as it WILL lock your throttle.

Quick recap what you need to do when using this file:

1. Assign correct radio system/module

2. Be sure the channel order is correct, including reverse of output.

3. If your flying a typical bind and fly you must probably adjust pitch travel to not exceed 11-13º max pitch depending on which model you fly.


PS: Use one your own risk. I fly Blade Nano cpx, Mcpx BL, Blade 450x, Trex 150 and Walkera V120d02s with these template. (But ofc modified values as curves, servo travel, reverse etc.)



V 0.75 Added Trippel rate Expo and travel rate. 

          Adjust auto lock time so its not so annoying but still locks if forget to put it               on.

V 0.7 Changed the way throttle lock works, so the timer doesnt count when giving throttle even trough its locked.

V 0.6 : Adjustment on Curve 1.
