HI all This is my first post on the Forms. I've been playing around with VTOL crafts. and i downloaded one and changed it to suit my needs. now it takes off fine. but i want to be able to change to my Horizontal jets once in the air. now. when both vertical and Horizontal jets are going. that is fine. the problem is when i turn off the vertical jets, then i just drops like a stone. Is there anything to stop it happening? Many Thanks.
