Order #10866 - Atomrc Dolphin V1.1 Rth Version - I can’t get it to fly without smashing into the floor

Order Number: 10866
Product Name: Atomrc Dolphin V1.1 Rth Version
Brand: AtomRC
I brought this from you very recently. Every time I use this plane it just ends up smashing into the floor on takeoff. I don’t know what I’ve done wrong or if it’s faulty. Please can someone help me- this is my first plane build. Thank you

PLEASE MESSAGE ME FOR FLIGHT VIDEO AS I AM UNABLE TO ATTACH DUE TO 20MB LIMIT
