Also known as LapRF V2. Best-in-class RF Race Timing System for races with 1 to 8 pilots. Nothing else on the market compares with this, period. 

The passing of a quad through the start/finish gate is precisely measured using the energy emitted by the 5.8GHz video transmitter on the quad, no external hardware required.

What's new ?

PoE Interface 

The 8-Way Event timing system includes an Ethernet port to allow direct cabling of the timing system into race management systems. V2 supports Power over Ethernet (PoE) 802.3at for simplified setup and reduced wiring. 1 Cable is all you'll need !

GPS Integration

Built-in GPS module provides an accurate real-time clock reference, enabling automatic time correction after a power loss, minimizing disruptions during events. Additionally, it will make split-time synchronization easier than ever, delivering perfect timing accuracy across all checkpoints. 

While this feature is not yet available in the current firmware, it is coming very soon.

Original LapRF excellence :

Race Proven, Expert Approved 

Race Proven at the 2017 MultiGP International Open, with 5 of the 8 tracks running the LapRF 8-Way. 

Race Proven at the 2017 MultiGP USA Championships, with two LapRF 8 -Ways running split times. 

Evaluated for over 6 months by none other than Joe Scully, the best race commentator in the business, and used for the vast majority of his events. Joe’s feedback was instrumental in ensuring that this timing system meets the needs of FPV race organizers. 

(And of course, IP67 waterproof, passively cooled, with no fans to suck in stray vegetation, commonly found at FPV race courses) 

No Transponders! 

The LapRF uses the Radio Frequency energy emitted by the Video Transmitter on the model to detect its presence within the race gate. 

The current generation of racing drones have two things in common - they all use 5.8GHz video downlinks, and they all need to be on different channels to race together. This is all that the LapRF system needs to precisely time events. 

No RFID transponders, no Infra-Red transponders, no complex installations. Just place the LapRF system in the start/finish gate, and start racing!

Analog AND Digital Compatible 

Well aware that HDzero is a rapidly growing system within the racing community, the LapRF is just as comfortable in the digital world as analog. Many successful mixed Analog and Digital races have been run with a great deal of success in the past few years.

Custom Timing Receivers 

Instead of using a standard receiver module in the timing system, ImmersionRC’s hardware engineering team designed a custom module, which can be calibrated on-the-fly to adapt to the different power levels found in races. 

Sensitive enough to detect passing quads, but selective enough to ignore adjacent channel interference. Heavily filtered to ignore off-band interference common at race events. 

To top it all off, we designed custom antennas with gate-shaped beams which let you precisely define the detection area of the timing system (something that competitive units sorely lack). These antennas are designed for RHCP/LHCP, and Linear polarization, covering everything that will be seen at a race event. 

LiveTime Integration 

The ImmersionRC LapRF Race Timing Systems are both supported by the industry-leading LiveTime Scoring Engine. 

Full integration of the personal system via USB, or the event system via Ethernet, including full auto-calibration of the timing system, and even a built in Spectrum Analyzer to analyze event background noise. 

Fully Waterproof 

As anyone in the Drone Racing business can attest, the weather at outdoor racing events can be a little unpredictable. To allow races to run after a shower, and to protect expensive electronics from being fully immersed in water, the LapRF 8 is fully waterproof. 

No fans, no moving parts, 1kg of beautiful anodized aluminum which doubles as a heat-sink.

I will read it again and refer to it often.
Format: Paperback
"I hope and pray that what I've written has been what you needed - comforting, relevant, and appropriately challenging insights and ideas that will guide you to have more peace, hope, and growth. I picture you feeling differently, thinking differently, and using new ideas for God's glory. " Dr. Kathy Koch In my current moment, the wise guidance offered in Dr. Kathy's latest book is a valuable gift. Where many resources fail or miss the heart of things - the thoughts offered by Dr. Kathy in this book are practical, God honoring, honest, accessible, challenging, real. It is common to find resources aimed at Jesus followers that land as impractical platitudes. It is common to find resources claiming psychological excellence that bury the reader in therapeutic blame shifting. This book is neither of those things and I am so grateful. With a grown married child, an adult estranged child, an adult child still at home, a pre-launched teen, an aging parent, a frightening and sad loss of purpose in middle-age...I am the center of the target audience. Each chapter brings focus to different areas of adult relationships that are prone to conflict. Each chapter ends with very useful tools to help focus on areas of healing and growth. The prompts for intentional, grace-filled communication are clear and immensely useful. There is compassionate seeing, firm challenge, and hopeful help. This book goes on my reference shelf for easy access!

What Do I Do When My DIL Wants to Cut Me Out of Her Life Along with My Granddaughter?
Format: Paperback, Format: Paperback
Answer to my question in my Review Title: I pray and God provided me this book! I just finished reading it, and I just couldn't wait to write this review! I highly recommending reading this book, if you are having any problems with your adult children, especially chapters 9-11. For me, like the title says, I didn't know what to do when my DIL said, "... I will be stepping back from contact for the foreseeable future. This includes cards, letters, gifts, or other communication unless I say otherwise." Since receiving that text message in December 2025, I have been praying about what to do. Just last week, my son texted me some very angry text messages, even demanding that I delete all virtual pictures of my granddaughter and giving him all my physical pictures of her (which I will do because of Matthew 5:38-42)! What amazing timing though to be reading this book! Praise God! My son has not closed the door yet on our relationship, so I have hope that I can implement some of the ideas in this book! See photo to see my notes (i.e. questions) that I wrote from the book that I could possibly ask him, if he is willing to meet with me. I pray that he does. Thank you SO much, Dr. Kathy, for writing this book! God is using you and your ministry. God bless you.

Timeless Wisdom with Real Action Steps
Format: Paperback
I was blessed to read this book prelease and am delighted to share that this book is a must read for all parents with adult children. Dr. Kathy provides very helpful insight in first understanding the foundations of the relationship based on the core needs of the parent and the child. Her explanations are very convicting but I don't feel condemned for previous shortcomings; rather I feel inspired to improve and apologize. I particularly appreciate the realistic action steps and examples of actual words to think/speak in the first person so I can retrain myself to think, speak, and relate to my children. Dr. Kathy equips readers by providing step by step explanations of 1) What to do; 2) Why it works and; 3) How to do it . It is brilliant and so helpful. However, she does not provide false hope because sometimes love is not enough in the case of prodigals and she shares Truth with parents and acknowledges the the very real pain and loneliness that can result then follows-up with real action steps and reminds us of our hope in Christ. As always, the wisdom in the book is timeless and can be applied across multiple relationships in life including my relationship with my own parents where I am the child and even in communicating with my husband. I am grateful for the Celebrate Kids ministry and Dr. Kathy. I am constantly learning something new and am grateful.

Real action steps. You will love this book!
Format: Paperback
If you have adult children, I promise you will be blessed by this book. So many times books have good insight, but then when life happens, it is easy to forget the wisdom of the book. This book is different. It has real actionable steps that you can take to help parents let go of their children. As we raise little people, it’s easy to wrap your identity up in your family life. This book helped me see where I was still finding identity in my kids and how to make sure that we are finding our identity and healthier ways. She includes a Declaration of Release in the book. Reading it brought tears to my eyes. It made me realize it’s OK to grieve the young family we once had but also to embrace my growing and maturing adult children. I want to have a healthy relationship with my kids and their spouses and I’m confident this book is like a very wise friend offering advice and walking this path with me. I was blessed to read a free copy of the ebook but I’ve already purchased my own paper copy of the book so I can make notes and refer back to it more easily.

A little too strong on religion and preachy, which I could have done without.
