Probably the dumbest thing you ever heard!!!
Well guys,i don't know how to put it.....For the past year,i have been flying my belt.......BACKWARDS!!!! Let me explain.The correct rotor direction looking the heli from the back is ccw,well,i've been running mine CW!Still though with the blades on the head and on the tail put for the correct rotation ccw!I haven't even noticed until today!
First i thought,nah can't be that dumb,i have the wires on the esc the wrong way.So i flipped them and the one way bearing wasn't engaging!Imagine my surprise when i realised that i've been flying that way for a year!I didn't even know it was possible!Probably when i had changed my main gear back in the days i had put it on wrong and didn't notice untill today Tell you something though guys,i'm not ashamed!Because there are some thing that don't simply embarass you,but makes you think am really that dumb? |

OK, first of all, looking down on the main blades from above, they should be turning clockwise.
Looking at the tail blades from the right, they should be turning CCW. Or putting it another way, the blade that's towards the front of the heli should be moving up. Are you sure you have everything backwards??

People have flown with one blade on right and the other backwards, flown with both blades backward, head rotating backwards, tail rotating backwards, you name it. So don't feel bad, because many others are guilty of the same or worse!
Though +1 with Dave, the way you've described it, I think your understanding is backwards and you were right all along? |

That's me Mike. I have flown, actually hovered for a few seconds, with one blade on backwards, until I thought, mmmh, that sounds terrible. Imagine my surprise when the head stopped. I couldn't believe I had done it. My own incompetence almost took my breath away. Done the same with the paddles too, including having them both backwards. Seem to recall that it flew okay that time.
Cheers Sut

I'm with Dave here, if I read your post right.
Put your bird on a table. Put your finger on the head and rotate the head clockwise while looking from above. First, you would notice the head rotates freely. This means the one way is released, like you are auto-rotating. Then while rotating the head in a cw direction still, look at the tail blades, they should be rotating ccw. The tail blades must rotate so that the blades leading edge rises up into the main rotors wash. If it does then it is correct. Don't fret looking dumb by asking. We all do stupid stuff all the time, even me. I've been married twice!

I mess the blades up all the time.
I've even messed them up on my co-axs, all 4 blades

I recall the posts. Don't feel bad, I've seen highly experienced 700 Nitro/E owners stick they're blades and paddles on backwards and fly. Land and check everything over and STILL not figure it out. Heck, even I've mounted blades on backwards, thankfully I noticed before I flew, because honestly, I'd probably not figure it out during or after a flight. LOL Nice... LOL... The jokes I can crack right now. |

Man i love helifreak!I feel better already!
Turnes out my head is ok,but i've been running the tail the wrong way!Probably hadn't flipped the belt the right way.All the cursing the esky gyro got hahaha!I was always like...Damn gyro can't hold $hit!Always drifting!But that's ok,the helifreaks always told me that this way you learn to fly better,always correcting the tail.Imagine me trying to learn forward flight with the tail the wrong way....Good times! Anyways,i tried the belt with the correct setup on my backyard!Damn,that was awesome!So little tail correction!I felt like i could fly with one hand and drink coffe with the other |

All Right!!!! Just make sure you use a lid on the coffee. Spilling hot coffee on yourself while flying a heli could result in bad things.

not to hijack the thread but we're all learning - which edge is the 'leading' edge?
Thanks, Fred |

Not a problem. Look at the cross-section of any blade. Doesn't matter which it is, they are all the same. One edge will quickly rise the tape off gradually. The thick edge is the leading edge. It causes air to speed up as it passes over it trying to catch back up with the air mass it was just seperated from. This is how lift is generated.

Purely out of interest, why is it that RC helis spin their blades CW and have the tail accordingly mounted on the right, but real helis do it the other way around (blades spin CCW and tail on the left)?

Luke, some RC heli models do spin counter clockwise, also some models have the tails on the left (look at some MA models, the Avant Aurora's etc.). It actually makes no difference which route they go, aside from a parts stand-point as one way bearings etc need to be selected based on the rotation direction.
It's more of a design/choice thing for the manufactures than anything. |

Not to throw a kink in theory here but with over 3k flight hours logged as a crewman on heli's, and countless times that I was the landing signalman, I never noticed a lean during landings. Of course I could blame that on the fact that the bulk of those landings were on board the USS Midway which had a 5° list.

You probably wouldn't notice a hovering list on a 1:1 scale heli (it gets smaller as the heli gets bigger) especially on a moving landing deck, but we know it's there.
You might get lucky and see it if you watch up close a helicopter landing on land, but then again, probably not on the big military transport. For the sake of science I'll ask a buddy of mine, he used to ferry around sightseeing tourist in Finland on the 4 or 6 seater, can't remember what model, but it was a piston engine.

Maybe just to be different, or maybe to help out scale modelers , the Eurocopter AS-350 has main blades rotating clockwise and tail rotor on the right.
