hi

I’m having problems when I try to prop hanging my model does not want to climb to a 80 or 90 deg vertical. I balanced the model recommended (180mm) and I also use a CG machine. When I changed the prop to a 11X4 this made more improvement then 12.25x3.7.What prop should I get 12x4 or a an other recommended prop 13x4w?

The motor is west 50 T1 + pipe and 12.25x3.7 model hype 3D

thanks alan
