Hi,

This winter I will make some brainstorming around the accoustic speed mesurement method. I plan to develop some friendly soft working live.
In order to find some parameters I need a backup speed info.
That's why I invested in a eagletree stuff.
I instaled it in a laser arrow and I will take this oportunity to tell you the real speed of that plane.
Actualy it's fit with a magnum 45 standard exhaust turning APC 9*7
after speed mesurement have been made with that engine i'll switch to a 61 FX.

feel free to ask me to install any prop on those combo just to see........ (don't ask me to buy similar engine than your )

actualy I estimate the top speed around 100 MPH with the magnum 45 (maybe a bit less), we will see as soon the weather is ok if my estimation is correct.

I also bet that the top speed won't increase a lot with a .61 FX
