In the second picture it looks like the wing panels are really twisted. It may just be the effect of the camera lens. Photos I take often make things look skewed.

The plane looks good though. The covering looks neat. The LT 40 is a wonderful plane and should fly nicely for you. I think the model is still going to be very tail heavy even with the battery. Be sure to balance it per the plan.

If you need nose weight a quick way to get it is a Harry Higley heavy hub. The farther forward you put the weight the less you need. Nothing goes farther forward than the spinner.

good luck on it's maiden voyage!
