Did you get a prop? Master airscrew is about the best for learning, will handle some abuse. For that plane and engine I would say 11x6 would do you well.
The APC props are more efficient but brittle. The Master Airscrew props will take a bit more abuse. We fly our LT-40 with the Thunder Tiger 46 Pro and a MA 11x5 prop. We can put the LT-40 in a near stall condition then just hit the power and it will climb out of problems with ease.
The LT-40 is a large, draggy trainer (one of the best BTW) so a higher pitched prop is just fighting against that drag. You want low end torque - 11x5 may work better for you.
Also I didn't see any CA. You can get by without it if using an aliphatic resin adhesive such as Sig Bond or Tight Bond. I went through almost 2oz each of medium and thick CA. Oh, I saw this is the ARF. Ours was the kit. Then epoxy may be all that's needed.
The current version ARFs use wing bolts or rubber bands? I'd check if I were you.
And, the all important item to quickly get you in the air... A qualifed instructor!!! Also, getting some time on a simulator WILL help save some hours.
