Here we see the Big 5 mounted on top of the chassis in an Arrma Raider buggy. Not much room on the top of this machine, but who needs a body with a full roll cage.

Ever wondered just how fast your RC car is capable of going? Ever get into a heated debate with a fellow bash or race buddy over which of your cars is faster? Unless you’ve got access to a commercial grade radar gun, the answer is still just a combination of irrationally composed hypotheses and speculation … until now. With the Big 5 GPS meter, you can record the top (Peak) speed of your vehicle or anyone else’s for that matter. Monitoring and recording top speed is just one of the many features on the Big 5 so let’s take a close look to see what it’s all about.

The Big 5 can be mounted to pretty much any vehicle with hook and loop, double sided tape or zip ties. It records an array of data including, but not limited to Peak Speed, Average Speed, GPS coordinates and Peak Altitude. By downloading the GPS Logger app for free from Hobbico’s website you can upload your data to your PC or even Google Earth. In the app, you can also read the data from all recorded runs. The 3-button design of the Big 5 makes it easy to use and the small size makes it easy to mount almost anywhere.

We used our meter in a few different vehicles from Hobbico and recorded a few runs with it in our Associated Apex Drift Scion (Reviewed a few issues back in RC Driver). With a 2S 4000mAh 20C pack, we saw a top speed of 32 MPH and that was on a small, bumpy parking lot. In the GPS Logger app, you can upload your runs to view data pertaining to the duration of the run recorded, peak altitude, peak speed, step time and distance traveled. You can also switch between metric and imperial measurements in the software with the app. Long gone are the days of arguing all summer long over whose car is faster. Grab a Big 5 GPS meter and the numbers will speak for themselves.

THE GOODS
Opening the box reveals a small foam inner tray that holds the GPS meter and USB cord. The Passport meter itself is tiny (in comparison to the box), measuring only 64x37x20mm in size, and features a nice LCD display, three buttons around the outside and two external ports; a USB port and a charging port. The unit is waterproof and uses a built-in WASS/EGNOS/MSAS/RTCM, making the GPS system compatible in different countries. It also has a 10Hz refresh rate that provides fast response to changes in the vehicles’ position. I was curious as to why the box was so big so I pulled up the foam tray and found the instruction pamphlet. This pamphlet is huge when unfolded; let’s just say that I’ve seen actual maps that are smaller than this pamphlet! Thankfully the info for mounting, initialization and user modes is compact; it’s written in several different lan- guages for use around the world.

Once on, pressing the Mode button allows you to cycle through the different modes. These modes include Current Speed, Peak Speed, Average Speed, Latitude, Longitude, Altitude, Peak Altitude, Trip and Time. Yes, it records altitude, which means that not only will the GPS Speed Meter work with surface-based vehicles (cars, truck, boats, etc), it will also work incredibly well with aircraft!

THE WORKS
Greg and I looked around the office for something really fast to test the Passport Speed Meter. After a few minutes of, “What about this?” and “What about that?” we decided to put it in something that was built for pure speed; the Traxxas XO-1 Super Car. The XO-1 has plenty of room in it to mount the GPS and is capable of hitting over 100mph in stock form, so this became the test bed for the Speed Meter system.
After charging the Passport, we mounted it to the top deck of the XO-1 by adding a healthy strip of double-sided tape and firmly pressing it into place. The next step was to initialize the GPS system, so we took the XO-1 outside where the Speed Meter could get a clear view of the sky. After about 20 seconds, the satellite acquisition icon stopped blink- ing, letting us know the Speed Meter was ready to track our vehicle.
To verify the accuracy of the unit, we dug out our trusty Stalker Radar Gun and did some slow passes to see how the two compared. At lower speeds, both the Passport and Stalker gun were within a couple tenths of each other. Once we started gaining more speed, the gap between the Speed Meter and the Stalker started to lengthen; the Speed Meter would register about 3-4mph over (sometimes more) the Stalker Radar Gun. This was a bit of a concern so we decided to mount the Speed Meter to the hood of my truck and shot the radar gun at that. With the larger frontal area of the truck, the GPS and Stalker speeds were very close again. The low profile and lack of front end reflective- ness of the XO-1 was causing false readings with our radar gun, con- firming that the GPS Speed Meter, being mounted directly to the vehi- cle, was most likely an incredibly accurate measurement.

WRAP UP
For those of you that want to know how fast your RC vehicle is going, the Passport GPS Speed Meter is an excellent choice. It’s compact, easy to use and can record quite a bit of info on your run (or flight). There is even GPS Logger software available that lets you map your drive or flight using Google mapping products. While I’m sure most of you are chomping at the bit to give this GPS a go, I’m also thinking about other uses; jogging (distance, or Trip), swimming (the same, with waterproof), hiking (altitude) … heck, even attaching it to my dog to see how fast she runs! So the next time you get the question, “How fast does your RC car go?” you won’t just be able to tell them, you’ll be able to show them!
