The high accuracy RAM3 Recording Altimeter for Models flight logger holds up to 65000 altitude readings in its ample RAM capacity, yet is smaller and lighter than competing devices.

  • The Recording Altimeter for Models (RAM3) records altitude and displays it on your PC.

  • The RAM3 has a resolution better than 1ft, aided by reading every sample thousands of times.

  • The RAM3 holds up to 18 hours of data when sampling at 1 sample per second.

  • It has a tiny postage stamp size, just 20mm x 14.5mm x 7.5mm (0.79" x 0.57" x 0.30")

  • It can be set to sample at 1, 2, 5, or 10 samples per second, making it suitable for duration, high performance, and DLG models.

  • Use the free FlightView PC software to optimise launch altitude, climb speed, and sink rate. Note no CD included - download the software from here.

  • The RAM3 is suitable for R/C or F/F models, as it doesn't need to be connected to a receiver.

  • Operates on a 3.1V to 15V supply, so can be used with a single LiPo cell.

  • Only draws 5mA, so a 50mAh LiPo will be enough for approx 10 hours logging.

  • RAM3 bare weight 2.2g, or 3.3g inc the cable.

  • Connects to your PC using the supplied USB interface and cable.

USB Interface Installation Instructions
There are two steps to install the USB upload cable. First, the proper software drivers must be available so that your computer can recognize and install the cable when it’s plugged in. Second, you must determine what COM port Windows has assigned to the cable and set FlightView to match using the Setup menu.

If you’re running Windows 7 and connected to the internet, there’s a good chance that the USB driver will install automatically when the RAM3 USB Interface is plugged into the PC. If not please go to and download and install the driver appropriate for your operating system.

Once the driver is installed and the RAM3 USB interface has been recognised open the Windows Device Manager and look for the Ports (COM & LPT) entry. Expand this entry and you should see a USB Serial Port line followed by the COM port assignment. If the COM port number is greater than 9 click on the Advanced button on the Port Settings tab and change it to 9. Make note of the number and then run FlightView and use Setup => Com Port to set the COM port to match.

RAM 3 Altimeter

Pricey but it works! I put it into my Radian Plus and did several motor runs which showed that my eyesight was good for 800'. Glide slope was a lot steeper than I'd thought. Without a calibrated altimeter for comparison, it would be difficult to assess the accuracy but it gives a good idea of what's going on up there. My only quibble is that I had to wake up my ancient PC to get the program and readings. A Mac version of the software is urgently needed as I don't want to partition my Mac and run Windows.

RAM3 altimeter

The RAM3 works well for my purposes but it could do with more interval settings. It is small & light so ideal for models and other applications with limited 'lifting' ability. The software supports older M$ systems as well as the new. The price seemed high but I suspect that reflects the development that was obviously involved. Service and advice from Hyperflight was first class and gets 5 * from me.

RAM3 is a great altimeter - made me at better RC glider pilot, especially a better DLG pilot. Somewhat pricey, but quality costs I guess...

Very good unit and easy to use. Would be great if there were a couple more less regular logging intervals

Recording altimeter

This device is smaller than I expected and packed with features. Very clever setup and once the driver is installed (which took a little bit of head scratching to get the COM PORT configuration right ) works very well. I have an iMac and MacBook so I run a windows 7 virtual machine in VM Fusion and it was not difficult to get the USB adapter lead setup. Would be good if supplier had a version of the software for Mac though.
