All,
I inherited this model from a club member that crashed it while hovering:

It's a ModelTech Magic Extra - 40 size. I've got a Thunder Tiger Pro 46 on it and i have been experimenting with different size props. Currently i've got the following props: 11x7, 11x4, 11x6, 12.25x3.75

What would you all recommend for a 3D setup?

FYI, i know i could probably go 4-stroke. If you could provide suggestions for my TT 46 (budget solution) and a 4-stroke solution (if necessary), i'd appreciate it. Thanks in advance!
