I am an accomplished RC pilot looking to start some 3-D flying. I am thinking of flying the Hanger-9 ShowTime 90. I have been told to use the Saito 100. I am wondering if the Saito 125 would be a better choice in the long run? I have been told you need alot of power to weight ratio but sometimes TO much power can hinder the new 3-D pilot. Any insight into which engine would be best for my applications would be appreciated. Thanks . Keith
