A couple of tips on loops and rolls if I may?

[gazmk2]

Hi chaps,

Whilst I have no trouble with front flips, backflip and a loose interpretation of a roll, I can't seem to figure out how to do a nice big loop and keeping the forward speed, nor can I manage to make the roll very axial (I can only do them to the right and my heli ends up a good 3 ft to the right after I complete a roll)

Have any of you seasoned guys got any tips on how achieve the above? I love seeing a heli do nice big loops in FFF and nice smooth axial rolls!

Cheers guys.

If you have phoenix you should use your free introductory helpout.

Sadly no simulator! I have considered one a few times then went out to fly whilst thinking about pressing the buy button!

Big loops for me (and mine are huge with the TDR) start with FFF and pulling some back elevator to get it going up, but not enough to have it going nose first. You use the collective to pull the heli up, this keeps the speed up as its climbs. When your at 10-11 o'clock, start to pull a bit more back elevator to pull the nose over the top of the loop, and at the same time start backing off the positive collective. On the way down, I'm feathering the elevator to keep it circular, and start adding collective to level out at the bottom.

Rolls are all about collective timing.

I loop into wind, and roll with the wind.

I find the trick to doing a neat axial roll is to avoid too much collective during the actual roll. ie. little bit of +ve collective before the roll, then roll with zero collective, then catch with -ve collective when inverted.

Collective during the roll is what sends it off sideways.

Gary, are you doing stall turns? if not they might help as it sets you up for the assent into the loop & the descent out of the loop,,
just a thought ..

+1 on using collective to start the loop. Really need to get the power on to climb rather than elevator as that saps your speed.

With rolls. You really need to make sure you have good COG on your model and do them downwind to begin with. Again as Tom says. Minimal collective input and make sure your model is level going into the roll.

+1 for me with that.

I've been doing some steep dives from about 40 ft and because there is no transitional lift as it descends at this angle, cyclic adjustments are definitely needed which is also good practice for the drop out of a loop.

Get a sim. I couldn't do half what I can do if I had not had a sim to get the basics down first.

Loops are all about speed...

This means lots of collective. A quick walk through imagine a clock face being the loop we are entering from the left to the 6oclock position....

Get the nose down full collective, lots of speed.

As you get to 6 o'clock you want to raise the nose slightly.

When you be to 3 o'clock you want to be level.

Keep the collective on, When you get to 12 you want to be tail down.

This next 1/4 is important. You back off the collective ever so slightly and rotate so you are nose down by the time you get to 9 o'clock.

Then feed the collective back in and use the elevator to control that size and shape of the last 1/4

Remember when you get to 6 o'clock you want the same nose down full collective attitude that you went in with.

If you need I can do a recording.

Hello Ade-Law
can you please do one for me.

Thanks

Rolls are all about collective timing and nose down attitude to maintain forward speed.

Collective has 3 positions, don't feed it... + 0 and -

If you are too early or late on the collective then the model will travel. Try 2 point rolls to inverted stopping in knife edge.

Don't rush it the model will hang for ages

Cheers all, I can do 'em quite well, but it's nice to think about what exactly you do round the loop.
This has made me understand a little more.
"Don't rush it the model will hang for ages" is one thing I am learning every day.

I can see what it is you was saying now looking at that video. I am going to study that video and try to memorise it, then have a go on the sim.

Thanks Ade grate help

Thankyou for all your responses! Very much appreciated! I can do stall turns yes, and if I'm feeling brave I can throw in a pirrouette at the top but only on my 550 as it whips the tail round very quickly and stops dead!

I probably will invest in a SIM as they do seem to help with getting the stick movements drilled into you fairly well if nothing else!

Thanks again chaps, looks like Wednesday or Thursday until can get out again to try it!

I just seem to really enjoy seeing helis do these big manoeuvres over the tight and hard 3d stuff! You have mire time to appreciate what is being done! And a backflip on my 550 feels like you're cheating, pull back, pos-neg-pos and it flips inside itself!

Holding a nice big loop is making you work more for it as I see it!
