instruction:
1) throttle to 100%
2) bring the VTOL (left sidebar) up to max for vertical flight
3) nose down, so that you will gain speed moving front.
it has a top speed of about 175 mph which is pretty fast for a helicopter.
Landing
bring down the VTOL (left sidebar) slowly towards the middle (Watch out don't bring to down too fast), heli will lose the altitude soon, do not reduce the throttle (engine) until it touches the ground. Nose up while landing, which will reduce the forward speed.

@MrCOPTY, thanks for your upvotes buddy.
@Thorne thanks. This is a freehand build- but much influence from Bell 214 / UH1 series
Nice design!
