When I come in with the SR and hit throttle hold it drops like a rock.Not enough spinning mass to keep the blades going I guess.

I thought I'd add 10% pitch at mid stick in throttle hold to compensate for the instant loss of speed.
Took it up and back to try it out.Hit throttle hold at about 2 feet off the deck and it popped up about 15 feet like a bottle rocket.lol...Unfortunately,the blades all but stopped on the way up so my attempt to auto back down was bad.Not to mention the SR has no rudder in throttle hold so it came down fast and spinning.
It crashed into a row of trash cans backwards.lol....

No damage at all so I took out 5% of throttle hold pitch and tried again.Same thing.It popped up about 10 feet but the blades kept some speed so I autoed it back and caught it in my hand.That was hillarious.It flogged me pretty good.Not a fair catch

Still no damage so I have the lipo on charge and I took out another 2.5% of pitch in throttle hold mid stick.

If that doesn't give a smooth landing I'll just learn to pump the collective a little when I hit throttle hold but it does drop fast.

I literally never use the word literally right.

How do you guys shut down your little helis?
My Trex 500's shut down smooth with identical pitch curves in throttle hold and ST2.

Should I just land it first?

The reason I ask is it tends to lean over when I land in idle up.

just land it in normal mode it's too small to auto plus no tail authority due to tail motor.

I just went through a couple more packs and all I can do is touch down before I cut the throttle.Or get about 6 inches from the ground first.

The tail just whips around every time.

I have an eRazor 250 that acts the same way.
I also have a new Trex 250 enroute and I guess it's the same?
Will the Rexie 250 auto with tail control?

I'm kinda new to the really small helis but I'm enjoying the crap out of them

Myself, I just run a standard curve in Normal, and spin down gradually with the left stick after landing. Flat curves in all modes makes no sense to me . . . . but then again, I am 97% a nitro flyer, and tend to set things up that way . . .

I have a linear curve in NORM and a V curve in ST1 and a flat 100 in ST2 but I'm just not used to switching modes in flight.

With my Trex 500 and 600 I got in the habit of starting up in idle up and landing in idle up.

I may have to start clicking back to NORM for landing but for now my idle up landings are getting alot better.I've been cutting the motor about 2 feet from the ground and it settles down pretty good with about 180 rotation.

My throttle hold switch throws in full negative pitch to slow the blades down quickly in Idle-up. It's more of a 'oh s--t' switch right
now as I'm still testing out a Flymentor system and don't fully trust it. I'd rather hit the ground hard than hit something/someone if it gets wonky. I run the cyclic stick with a thumbtip, but keep my index finger at the Hold switch.

Once I get more experience in flying, that will change to something more appropriate for auto-rotation landings should I get interested in trying that maneuver. But to me, it's mostly a stunt for an electric.
Any failure that takes out the motor is most likely to take the radio and servo power as well. Nitro is different.
