Holy crap! I get 180-183 mph! Might be more if the end of the audio passes were not clipped short. After passing the microphone the departing frequency is a little sloped meaning the audio track was edited a little to soon or the lipo was sagging voltage or the model changed direction.

Brilliant - thanks Don! Yea, I wondered if I cut those clips too short. The plane needs some trim work too. I'll try again later and eventually I'm going to go to 5S.

Thank you again! :-)

Hi Don!

Any chance you could look at my pass? Air temp 13C

Doppler (0 min 12 sec)


Loading the soundfile into "WAVEoScope" program I get around 250km/h +- 25km/h. But I'm pretty sure that is too high.

The model is a Rifle 1m on the recommended speed setup that should reach around 210km/h

Thanks!

Great! Yes that sounds more reasonable and in accordance with my GPS for that pass which said 221 km/h.

Thanky very much for taking the time!
