Can somebody tell me the inputs for a piro-flip and a funnel where the heli is right side up and the tail is down.

Instead of giving you the "if you have to ask how to do a manuevre, you're not ready for it yet" line, which I completely don't believe in, I'll actually give you some information!

As far as piroflips go, the trick is synchronizing your cyclic inputs with the speed your heli pirouettes. I usually start with back cyclic when the tail is pointed at me, and progress from there. As the tail goes around, you stir cyclic. For left rudder, I believe you use clockwise cyclic. I would like to tell you for sure but its just one of the things my fingers remember.

A couple things to consider: doing slow piroflips is usually harder than fast ones. However, really fast piroflips are hard too (and can be dangerous depending on your ship & setup) so selecting a good pirouette speed is crucial. You can usually adjust this by tweaking your rudder ATVs.

Also, the amount of cyclic input you give determines how many pirouettes you'll do, per flip. Lots of cyclic = few pirouettes per flip; little cyclic = many piroutettes per flip. Small cyclic based piroflips tend to look neater to me, however they also seem harder to perform gracefully.

Good luck!

Funnels

Good info on the piro-flip. Here is some on the funnel.

I start with forward flight and transform this into sideways flight, then I drop the tail with aft cyclic, start adding collective, right cyclic and left tail rotor. Then it is really just a balance of these inputs, only practice will get it right. This will do a counter-clockwise funnel with the disc to center and tail down. I have found that once you find the "sweat spot" it is pretty easy to hold the funnel for extended periods, just finding the spot takes practice.

Try the "Search" function also, there are volumes of information on about any trick already written within the bowels of RR.

Hope this helps,
Pete

Thats something I have trouble with too, I've been trying to link funnels into a death spiral, but I find that I lose so much altitude on the funnels that my altitude is marginal for the death spiral, and I normally just pull out rather than risk crashing.........kind of ruins the effect if you have to climb out again before starting the spiral.

I find that if you are losing altitude on the funnel you are either too steep or too slow. Either flatten it out a bit or speed up your rotation. I have been able to hold funnels with my R50 and R80 with just a little over hover stick position for pitch and I am about 60 degrees nose high. I am working on enlarging the diameter of the funnel now. When you find the sweat spot you can control the altitude with the collective.

You will fall out of a funnel if you aren't inputting enough rudder. This will cause the heli to knife edge fall really quickly. The other reason would be that you are putting in to much elevator for the amout of collective and aileron.

I don't fall out of the funnel, I just lose altitude tail down or tail up, whichever way i start from, but I think its just 'cause I'm trying to get too vertical, I'll try the 60 degree position and see if it helps. But since the Freya won't be ready for a few weeks it'll be a while.

In any event it looks kind of cool to funnel down as low as I dare and then loop out to inverted. Now if I could just get a little more confidence to go lower....

Sorry, when I say 'fall out' of the funnel, I mean that the heli is dropping toward Earth.

If you are trying to stand the heli near vertical, you need more collective and more aileron. If it starts to fall, it will fall faster than if you had it at a flatter angle.

I can attest to that. I had my heli at about 75 degrees tail down and just completed 2 and a half circles when my rotor speed started to decay but couldn't really tell because of all of the plank noise in the background. It slid back slowly at first but accelerated real quick...quicker than I thought possible until it met earth.... Be careful always practice a couple of mistakes high.
