This isnt directory related to the edge but i just got the staudacher last week and i purchased the rcs 1.4 for it after flying my Super Kraft Texas Hurricane today with a fpe 2.4 up i really think the fpe 2.4 would be a good choice for the staudacher . Some discussion has been mentioned about motor choice and that the 2.4 gas would be to much motor The Hurricane weight is around 12 to 13 lbs and i think it would fly it well The motor is super smooth and no virbration at all.
