When I flew some 25 years ago I never had to autorotate once. Now that we have Sim's I've been attempting to learn but just can't get it right. I can safely auto my Rex700 from 5 feet Any tips?

Gravity's a bitch ant it?

Practice doing decents in Normal mode first. It is important to have a good 45 degree line coming down and keep the heli flat. When you get about 10 to 15 feet add some collective to flair. You don't need to land but just slow the heli down to a hover. After a while it will become second nature then you can start flipping the switch to auto rotate.

Carpe Diem!!!

If you can auto from 5 feet then you can auto from 55 feet. It just takes longer to get to the ground. The two mistakes I see when pilot make when starting to autos is to hang out upstairs too long in which case they burn off too much headspeed and don't have enough to land nicely with. Or they try to come in a too shallow of an angle where it looks more like they are landing an airplane. In this case they end upp with too much foreward speed that they need to burn off in addition to managing the vertical decent. Do what kc8qup said and keep at it. Autos are the one manuever that pays dividends.

Also, on FBL helis its a good idea to go to full negative as soon as you touch down to cut down the chance of a tip-over.

Good Luck

I'm working on this myself and have a question.

Right now, I always land my Raptor 50 and B450 in baby autos. Hit TH, add positive pitch so that I float down.

If I'm coming in from higher up though, I've been using negative pitch to push the head speed up and then flair gradually as I loose altitude along with cyclic input.

Is that how it's supposed to work?

Thats What's happening 9 out of 10 times. (On the sim of course.) Tip over... I am FBL so I'll give that a try too. Thanks again

Practice makes perfect. A day with a nice steady breeze will help greatly. After practicing your decents, go back to the baby auto's and work your way up. The wind will add lift making your baby autos effortless and allow you to go higher. It is scary, its not natural to kill the power. It goes against everything you know. But, once you get used to it, it becomes easier and will end up saving you time and money in the future.

Walk on water long enough, eventually you will get your feet wet.

Yes. That's how it works.

It's all about balancing the rate of fall with the amount of head speed. Autos are the easiest when you have a light headwind. You will have the most hang time at the bottom. Don't practice autos with a tailwind until you are pretty comfortable.

The more headwind there is the more you need to drop the nose and fly it more like a plank to pentrate the wind and land it where you want. If you are coming hot (fast forward speed) the pull the nose up while still at 4ft and slow heli or stop it if you feel you still have t he head speed. As soon as its slowed enough or stopped level the heli and settle it down just like you do now.

I have played around with coming in real hot and then pulling the nose up at a 60 degree angle and removing pitch so the heli wouldn't stop like it hit a wall. Then at the instant it stops level it out and set it down. Lot's of fun. That whole paragraph takes less than a second to execute.

As I was writing this I realized how hard is is to explain in detail something that I can do without really thinking about it.
I'm sure I done thousands of autos over the last 10 years.

BTW, Every landing I do is either a full or baby auto. I never land under power. I use the flare to bleed off as much head speed as I can before touch down. I switch in to Idle-up2 before lift-off. Maybe its weird, but that's me. At least I never have to worry about forgetting go into idelup before going inverted. I hated when that used to happen.

Some models are more prone to tip than others. My first FBL heli (a converted Hirobo EVO with a CGY750 V1.10) had a real tendency to tip. My two Velocity 50N2's with CGY750 V1.20 and now V1.30 don't seem like they want to tip at all. But I still do a couple of things to prevent it. First, don't input any cyclic while on the ground. Second, I kind of pop it off the ground rather than do a real slow lift off. And third I try to get the heli level and stopped before touch down. And then remember rule #1 LOL

I personally fly the Futaba CGY 750 and have flown many other helis with Beast X and a few V bars. No issues with tip overs on any of them. Takeoff and land all of them as if they had a flybar. Maybe the only difference is not to take off too early with a low headspeed. But you can absolutely take your time and "fly" it off the ground.

Luckily,tipping on the sim since I never tried it for real. The full negative pitch at touch down made a huge difference. I'm running the BeastX so maybe if I get the nerve to try it for real I might find it easier then the sim. On the simulator,I set up the heli with 1oz of fuel then fly it till it runs out so I never know when it's coming.

Since I learned the auto technique years ago, I have never landed without an auto. The more you use it, the easier it gets.

Same here. I'm not sure I remember how to land under power.

Learning to auto a 450 makes all of the other sizes a piece of cake. The larger sizes are much more forgiving.
