Thank you Don!

Hey Don, can I get a best pass from this video please?
I have better batteries on the way, I pulled Data logger out and on 6s it was flying at 20.1 volts..... I am curious to see how much I pickup with new batteries by next weekend, thank you sir, Joe

The only real dopplerable pass was the one at ~55 seconds. I got about 136 mph. Later passes show voltage sag and the model is a littel too far from the microphone. I would try to get the recording device as close as possible, I use my cell phone voice recorder and lay it out on the field then fly over it as low as I feel comfortable. The closer you are to the microphone the faster the doppler shift happens and the more accurate the reading will be and also the less effected it will be by voltage sag.

Don

Hi Don I appreciate the effort.... I will go with the 136mph. The field I fly at as you could see on the video has a lot of obstructions..very difficult to do any low passes over the runway with out hitting the bushes or a storage shed adjacent to the field. Plus the guys next to me were freaking out seeing a small plane fly that fast. Anyway,thanks for taking the time to do this.

Any chance this offer is still on the table?? Just started using waveoscope and would love to know your method for getting the best results.

See post #2 in this thread.

Don

Forgot to edit after I went back and read the thread. Highest pass for me yesterday was 107mph Was confirmed by my friend on another forum. Your guide there made it insanely easy. Thanks Don!

Can I see if I picked up any more MPH with new battery Don?Thank you, Joe

Habu 2 @ field (2 min 7 sec)

Going to need some time on this one, the fan "whooshes" too much for my normal quick program. What was the air temp?

Don

77-79 degrees....was a pretty morning for a change.

I got 120 mph assuming 72F air temp. Also I get 31326 rpm.

Cool,I know that fans quiet,thank you... I have a lil flying wing with your wicked outrunner with a 4.1x4.1 that I should have a video this comming weekend, should be a lil hotrod.Flown it a couple times to get a grip on it now its ready for the bigscreen....
