Hand Launch Assist (HLA) Setup
The following prerequisites are required for HLA setup:
• Complete the First Time Setup
• Complete the First Time SAFE Setup
• Configure a flight mode tuned with SAFE angle demand
Setup Procedure
1. With the receiver on and bound, enter Forward Programming.
2. In Forward Programming, go to Gyro Settings > System Setup > Hand
Launch Assist.
3. Configure the parameters on this page as follows. Aside from the HLA
flight mode, most defaults are typically a good starting point.
a. HLA Flight Mode: Assign a flight mode which has been configured
and tuned with SAFE Angle Demand mode enabled. Having the highest
SAFE gains as possible for this flight mode will yield the best results
regarding the model properly achieving the desired climb angle as well
as leveling itself from prop torque or poor launches.
b. Threshold G's: The default of 1.5 G's is a good starting point. If hand
launching is not activating HLA properly, reduce this value. Increase
this value if less sensitivity is desired. The max X axis G's value listed
on the transmitter telemetry is a good way to gauge acceleration being
reached on launch.
c. Threshold Throttle: Required throttle input % when launching the
model to allow HLA to activate. Value should be the minimum throttle
that is typically applied before hand launching the model.
d. Duration (S): Duration in seconds for HLA to remain active after hand
launch is detected. 2 seconds is an adequate starting point to give the
model time to climb and allow the pilot to put their hands back on the
sticks.
e. Pitch Offset: Pitch up angle in degrees which will be applied when
HLA is activated.
4. When the HLA configuration is done, go back to the Gyro Settings menu.
5. Enter the F-Mode Setup and select the Next page option.
6. The Hand Launch Assist option determines in which flight modes HLA is
activated. Set this option to Act for any flight modes where hand launching
may be desired.
Hand Launch Assist Testing and Operation
To use the hand launch assist, the following conditions must be met:
• The model must be freshly booted. HLA will always be ready after the first
boot.
• Once the model has activated HLA during flight, it can return to a ready state
if the following conditions are met:
- Throttle is less than 5%
- The model remains totally still for 2 seconds (the throttle must remain
below 5% during this time)
Follow these steps to activate hand launch assist:
1. Set the flight mode to a flight mode with the HLA active.
2. Increase the throttle above the threshold throttle value entered in the HLA
setup.
