Hi Mattew,

        The drop of last while flying is quite small. Don't count on that. 
There have 
been some articles in german magazine which measured only a couple of % using 
data loggers. Also you want to put the engine full throttle during the launch 
phase, don't you ?
        Is there anything braking the engine ? Are the cables too close from 
the 
rotating part, or something of the kind ?
        
Cheers
Martial
