It deserves a five stars however need a bit work
You can hear at 0:27 and 0:31 in your video the sounds mismatch like two engines at the same time may the recorded sounds different RPMs. I hope you can tune a bit this transition
I tried to fix it in v0.3 but I'm not sure if I understood what you was speaking about. Plus the video was on version 0.1 and you must have downloaded version 0.2 when you reported the problem. Try and tell me :)
sound is very good. there is a bit of distortion below 8500 rpm on the internal camera. you do not hear it on the external. If that could be worked out then 5 stars all the way.
