Wrong plane 4 birthday
If you ever want her to buy you any R/C related gifts in the future, you'd better keep it and build it. Tell her how nice it was of her to get it for you. If you make her feel she got you a plane that you liked then she'll be more supportive of your hobby.
If you tell her it was all wrong you can count on getting clothing as gifts for the rest of your life.
Think of it as an investment in your R/C hobby future.
