In flying real helicopters, one of the exercises during training is the quickstop. It's one hell of a coordination tester (over and above hovering itself).
Basically you transition away (gradually picking up forward flight, keeping the helicopter the same height above the ground) until you reach about 40 knots and then begin your climb out. But then you pretend that you have to stop fast (maybe birds have flown up in front of you). You have to:
- Pull back on the cyclic, which means you start to climb so you
- lower the collective, which means less torgue so you
- adjust the rudder pedals
- and then as the helicopter pitches through the vertical and tilts nose up (to begin decellarating), you have to
- raise collective because the helicopter start to decend, which mean
- adjust the rudder again
Oh yes, I forgot: on the piston helicopters you have to adjust the throttle through all this too.
At least your collective and throttle are on the same stick, and you've got the gyro to help you out, but it's still a tricky exercise.

After three tanks i could no longer hold a side in hover as my eyes started to lie to me about the helis orientation. After tank 4 the orientation problems were creeping in during tail-in, so i went to the pub to watch the football rather than risk the wrath of the Dumb-Thumb God.,

I read somewhere, I think in Ray's Helicopter Manual, that two tanks are the maximum, otherwise you'll start getting what you experienced.

Sunday i turned up at our club with a delightful wind blowing, sat around a bit trying to get some inspiration to fly. Another pilot turned up so i watched him hover for a bit to gauge the wind.
I decided what the hell and tried to start the heli but the starter wouldn't even turn the engine. 1 stripped down heli and a lot of very patient help later and the bird was running sweetly again.
1 tank of fuel to get the feel of it again and then the dreaded nose in. After about 30s sliding around on the deck, raised the collective and there she was, nose in about 3 in above the ground.

When I joined a club, the first tip I got was to face into the wind, that way the heli will weathercock into the wind and I'll be helped.
I've never been able to do a piro like you though :-) I need more practice on a simulator.

Managed some good nose-in hovering by the end of the session and finished with a 360 piro in each direction.
I'm loving this hobby, and now that i'm not so scared of the wind i hope to get through the next gallon of fuel in less than the 2 months its taken me to do this one.

After a couple of years and I'm just getting to the bottom of my gallon of fuel :-(
But now I've just bought an electric I hope to get more flying done!!
I'm really impressed you did a couple of pirouettes even though you're just starting out!! I bottle out when I get a bit beyond side on hovering.
