Hi/Lo rates vs. Spektrum flight modes (SAFE, intermediate, advanced) - Need explanation

[Flyboy666]

I've looked all over the web and can't find a simple explanation on this, so I am hoping someone can help:

What is the relationship between Hi/Lo rates, and Safe/intermediate/Advanced modes on Spektrum receivers?

Spektrum says that "In the upper, or “HI” position, servo travel is 100% on these channels. In the lower, or “LO,” position, servo travel decreases to 70%."

I am not clear on what they mean by "servo travel," and how this relates to the three flight modes. Is that how much of available travel you have for the flight controls? For example, on Lo rates, does that mean that the rudder, aileron, and elevator will only move 70% of its potential range of motion? And if so, how will toggling between the three flight modes be affected?

For example, let's say I am in Expert mode, Hi rates: So I have full travel of the flight controls (elevator, rudder, ailerons). So I can do rolls, flips, etc. If I move the rate switch from High to Low, does that mean I am now unable to do rolls and flips because I am limiting the amount of control surface travel? And does that mean that I am basically mimicking Intermediate mode/hi rates now?

And for simplicity's sake, since I am a new flyer, should I simply stay on High rates?

Hopefully this example helps illustrate what I am confused about: basically how rates relate to the three flight modes (SAFE, intermediate, advanced. That is, what is the relationship between the two.

Hoping someone can clarify. Thanks

You lose 30% on any servo in airplane..For a new pilot you stay in safe mode till you skills improve..and no in Lo it will take you longer to roll turn any action you try

The relationship between Hi/Lo rates and the Safe, Intermediate, and Advanced modes on Spektrum receivers involves how the transmitter controls the model's response and behavior during flight.

Hi/Lo Rates:​

• High Rates: This setting allows for more movement of the control surfaces (like ailerons, elevators, and rudders), resulting in a more responsive and agile model. It's typically used when you want greater maneuverability, such as during aerobatic flying or when more aggressive control inputs are needed.
• Low Rates: This reduces the movement of the control surfaces, making the model less responsive but more stable and easier to control. It's ideal for smoother flying, such as cruising or when you're getting accustomed to a new model.

Safe/Intermediate/Advanced Modes:​

• Safe Mode: This mode is designed for beginners. It limits the bank angle and pitch of the aircraft, making it difficult to enter dangerous attitudes. It typically has self-leveling features, which help to stabilize the model if the controls are released.
• Intermediate Mode: This mode offers more freedom than Safe Mode but still provides some level of stabilization. The bank angles and pitch limits are less restrictive, allowing for more advanced maneuvers while still offering some protection against extreme attitudes.
• Advanced Mode: This mode provides full control with no limitations on bank angle or pitch, giving the pilot complete authority over the model. There is no automatic stabilization, making it suitable for experienced pilots who want to perform advanced aerobatics and have total control.

Relationship:​

• Hi/Lo Rates with Safe Mode: In Safe Mode, you might prefer to use Low Rates, as this combination makes the aircraft very stable and easy to control, ideal for beginners.
• Hi/Lo Rates with Intermediate Mode: You can switch between Hi and Lo Rates depending on the level of control you need. Low Rates can provide a safer, more stable flight, while High Rates can offer more control for maneuvering without completely disabling stabilization.
• Hi/Lo Rates with Advanced Mode: In Advanced Mode, pilots often use High Rates to take full advantage of the model’s capabilities, as this mode doesn't restrict the aircraft's attitudes and is used for performing complex maneuvers.

Understanding these settings helps pilots tailor their flying experience to their skill level and the type of flight they want to perform. The combination of Hi/Lo rates and flight modes can significantly impact the behavior of the model, making it more versatile across different flying scenarios.

Thanks, very helpful explanation.
A question about Advanced mode: Generally speaking, if I am in Lo rates in Advanced, can I still do rolls and loops, or do I need to be in Hi rates so I get the full maneuverability and full movement of the control surfaces?

As an FYI, I am currently flying an Aeroscout (am still in learning phase), but I am thinking your answers above would apply to any plane.

Thanks

You will still be able to do rolls and loops in low rates, it's just takes more room to do them. make sure you are not to low when you attempt it.

I think high and low rates are the % of control surface throw for your 3 axis points. I program my Specktrum 100% for high, roll it down to 75% for low rates. And the response time to 30% for my style.
