Well I've gone the crash route a couple of times already. All in the name of having a blast.

I know I'm not that advanced yet but when I'm ready I'd like to know how you all first prepared yourselves to get the nerve to cut the throttle?

Do you stay a good bit up from touching down and then switch back to normal and recover? Or do you risk the flub and rebuild?

I'm logging all sorts of sim time waiting for my rebuild parts. I've been working on autos quite a bit but that's too predictable. And yet I still only land about 30% of the time.

i did my first auto a couple of days ago with my R60 and it went great. didnt really prepare.. just went up really high, switched the throttle hold and voooom the heli went down at a good stable speed. ... flared when i got low and wooohooo my first auto. did a few more with my R60 and they all went great.

then i tired doing them with my bro's caliber 30 and man that sucker drops fast! much faster than the R60 and i flared at the end but didnt judge the hight right and bam , boom strike. it wasnt bad.. more like a small dent but it had to be replaced. nothing else happened to the heli so i was lucky.

so my tip is make sure you have -4 on your mains and setup your throttle hold to idle. then go up really high and flip the throttle hold... when you get close to the ground (20' - 30') just flip back the throttle hold and power up... that'll get you out of it with enough time.. do that a few times untill you familiarize yourself with the way your heli behaves during an auto. Once you feel confident do a full controlled auto...


goodluck,

practice on the sim.

When you can do 10 out of 10 on the sim, real life will be easy.

If you have some good CF blades, your energy will not fade quickly.

What I recommend to take the nerve out sit on the ground and get your collective up until it is just about to hover, then click the throttle hold and ease up on your collective. You'll float off the ground, and you'll be able to land easily.

Then while hovering a few feet off the ground do it again. You'll drop fast at first, but after putting a little positive, you'll float down easy.

Then do it one time in FF and try it out. I hardly ever turn off T-hold before I hit the ground, because I don't like my tail whipping around when I flip the switch. I guess I was fortunate and haven't had a bad (planned) auto yet.

Well, I've posted this on a few other sites, but I'll do it here too... Here's how I suggest you learn to auto....

First, go find someone who can auto like a mad-man... Give him your bird and say "here, auto this sucker"... This isn't to see if your bird is capable.... It IS... This is just to give you a little extra confidence.... It makes your finger a little lighter when the time comes... Just KNOWING that your bird CAN and WILL auto easily...

Now it's time to have some fun... Here's what your gonna do... First, let's make sure your bird is trimmed out properly... Unless you have a driven tail, your going to want to make sure you program in some "changes" to your radio when that throttle hold is thrown... First, set it up so that when the throttle hold is thrown it sets your gyro into standard rate mode... Second, you want it to also throw an offset to the tail rotor to make it 0 degrees.... This should keep it from kicking the tail on you when you switch, create less drag as your coming down, and keep you from kicking the tail again if you abort.... Spool the blades up and just barely get it light on the skids... You may have to adjust the offset slightly till the tail doesn't try to kick when it's thrown.....
Next you want to lock those blades down... (by the way... Autos are much easier with glass or CF blades... The woodies are much less effiecient and just don't auto as well... If you only have woodies, don't worry, they WILL work, but it's just a little more difficult..)

Okay, your ready for your first auto now... But don't worry, this is gonna be easy... First, set your bird up like your ready for a take off... Before you do though, go into your radios throttle hold setting... Bump the throttle up... You wanna bring it up till it's beyond the point of engaging the clutch... Yes, in effect, you are probably going to have MORE power being delivered to the blades in throttle hold than you do when the stick is all the way at the bottom... (Your normal bottom stick should be JUST past the point of engaging the clutch... Go a little further than that with the hold)...

Now get the bird up about 100ft downwind... Kick it around to point into the wind, point the nose down a tad, drop the collective stick and at the same time throw the throttle hold... DON'T WORRY!!! You've got a LOT of reserve power being fed into the blades... Remember your clutch is never disengaging... Keep the nose pointed down a little and bring her in... When you get about 20ft or so you want to start feathering in a little aft cyclic... When you do this you'll not only bleed off a lot of forward speed, but you'll also slow your descent rapidly... Now as your bleeding off most of the forward speed and getting closer to the ground start feeding in some positive collective to slow yourself down... Again you should have plenty of reserve power now, so you'll be fine... Set her down nice and easy, and just as you touch down you might want to give just a tad forward cyclic... Congradulations... You just did your first auto... It's all downhill from here... Finger feels like it's lost 10 pounds already huh?

Now just bump your throttle hold down a couple of percent, go up and do it again... get comfortable each time and just keep on practicing... Before you know it your going to realize the throttle hold is back where it belongs and your clutch isn't even engaged anymore.... Viola!!! Your auto'ing with the best of 'em...

You guys are good. Thanks for the advise, it was just what I was looking for.

I'll keep at it on the sime until I get to the point where it's a no brainer. After that I think I'll set it up like the last post discribed with a little throttle to keep the blades in motion at first.

Thanks again. I'm sure there are a lot of guys like me out there that were looking for just this type of information and will find this helpfull as well.

When you can do 10 out of 10 on the sim!
Stuck in the house with a cold and an Arc load of rain outside, I've been hammering the sim.

I managed 8 in a row including all of the FF to get back to me as well as a few right and left hand circles flying the tail around me. Some nose in and tail in circles around me. All without a single crash. Then I must have gotten bored and killed it on the 9th Auto.

I did find that I wasn't adding positive pitch and flairing soon enough. Thanks for all the tips. I'm not sure when I'll try it for real but at least I'm understanding the mechanics a bit better.

Bump up ur throttle curve so you can barely hover in throttle hold. Do your auto.

Each time bump down ur throttle alittle bit at a time.

When you are comfortable, bring it down to idle and give it a go!

I like that idea. As soon as I get comfortable in real life with just flying I plan on working real hard on emergency manuvers.

If you change the pitch too positive too fast while in throttle hold, won't you kill the engine? Never tried this, im just assuming.

If this is the case, you had better be careful because in this case, you had better know how to auto already!
