Hi.
First of all do you have an airspeed sensor installed (eagletree)?
Then if you do have one is the "Launch" variable set to 1?
Finally you could use the "estimator_hspeed_mod" like this:
<attitude roll="0" throttle="0" until="estimator_hspeed_mod > 4" vmode="throttle"/>
It uses the ground speed instead and i use it all the time.
I run until i reach 15km/h and then the motor starts.
Have a look at this video where i fly it like this (i am the one who is sitting because i hurt my leg):
