Beginner with a blade 450

[hardrock]

Hey all great forum! I'm new to collective pitch RC helicopters and have a blade 450 with Dx6i transmitter. I've had this heli for almost a year now and not managed to fly it as something always seems to go wrong just before the heli leaves the ground! Watched countless videos on set up, and I'm sure I have the swash plate set correctly etc but still the bird seems to want to tilt over towards the right when spooled up. I've had a play with sub trims etc. The heli is relatively new and not had a crash as of yet!

Does any one in the Birmingham UK area prepared to give me a heads up on this heli.. Would really really appreciate that
