Following the plane with the radar gun will give you a slower speed reading then actual speed. The gun needs to be held still and the plane needs to fly at it (dangerous for the operator). The Speedster III model can be used on a tripod and set in continuous reading mode. Make a pass then go read the speed.
A doppler sound spectrogram reading will also be inaccurate if using the sound file taken from a recording device that is following the plane. Has to be stationary for accuracy.

Check out Voltron who have an onboard mini gps for about $80

That radar gun has been out for many years.

You need to be in line with the plane. The further you are off line the less accurate the reading.

don't move the gun when reading speed.. it can set the speed off by up to 15km

The new Speedster III with digital wireless display is out & could be reviewed.

Cool radar gun! One thing to keep in mind -- if there is wind during your speed test and you want to get a better estimate of the true air speed of the plane, measure the down-wind speed passes as well as the up-wind speed passes and then average them to help factor out the wind effect on your measurement. I used a doppler sound spectrogram & calculator (free software) of your YouTube video (audio) and got pretty good speed match with what your radar gun showed...

Azer831, the plane is scratch built or homemade not store bought. I probably built it for about 100 dollars minus the radio transmitter..

x1iD Thanks. Sorry for the delay replying. Oh man, sorry to hear about your plane. At least you had 2 days of flying! Well hopefully tyou were able to salvage some of the parts. I guess it all depends on what type of plane you want and your budget. Planes to reccomend, also depends on Flying Skill and style. I alwayr reccomend building your own. There are good RTF planes too, the Park Zone Stryker is a good ready to fly plane. It's just not as durable as some scratch built EPP planes though.
