built two mid stars with 46 ax, did it with two threads here in kit building forum.
battery behind the servos, it is flying very well, 11x5, 11x6 props, no prop clearance issues, build as a tail dragger.
You can change the landing gear.
Came out less the 5 lb flying weight.
I have also four stars, the mid stars are flaying better.
