What do you think About QQ Aircraft YAK-54 73" with Saito 1.25 installed ? Isn't it going to be enough ? The plane will be lighter with Saito 1.25 and it's not much havier than 69", so I decided that probably should be enough for flying and 3D, I am not power crazy but also don't want leak of power in my aircraft. As I heard 1.80 has problems with ball bearings and is very thirsty, and as I presume with 73" YAk-54 standart 12oz fuel tank I will have only 6-7minutes safe flight time in 3D.
Any opinion is useful.
