My biggest problem with the 120SR is that tendency of going elsewhere when you try to stop ... i guess probably due to the 45 flybar.. you release the sticks and it just pitches up a lot and then rockets backwards
Yes I have. And that was true for me. I struggled with my first 120SR flight's, quite a bit, after only flying a "toy" Syma S107G.
I finally got fairly comfortable with the 120, so I bought a B450 3D.
I took it slow and finally got to where I could keep the 450 in the air.
When I went back to the 120 it seemed so much easier than before.
The "rocketing backwards" does not seem normal. If working properly, pilots have been able to completely take thier hands off of the sticks for up to 10seconds, and the bird will hover, with 0 wind, such as indoors.
I have personally set the TX down on a table for maybe 6 or 7 seconds, and just watch the bird hover itself.

I went from the 120SR to a 300X for my first CP Helicopter. I skipped the 130X only because I wanted something bigger and had more power than the 120SR. It has been a whole new learning experience, only in the fact that when you let go of the sticks.... the 300X does not self level. If you have mastered the 120SR, you will have no problem going to a 300X. I also have a 450X, but..... it is HUGE compared to the 120SR, while the 300X is BIG compared to the 120SR.

+1 on "does not self level" I went from a 120SR to a T-rex 450 and just put a UH1-B fuselage on it. It is hand-ful but a great new learning experience. I still go to the 120 for in the house and outside. The 120SR is a great little bird and when you think you have mastered it," if you have a good TX," reset it to the " bat out of hell " setting and keep haveing fun. WS

"Rocketing backwards" would be caused by one of two problems. 1) The pushrod on the left needs to be adjusted. Center your trim. Hover your heli in front of you and note what the distance is that you have to make the rod move to keep it steady. Land and turn the ball link to that level. You may have to adjust the right link to compensate your left/right movement. 2) If the #1 technique doesn't work, it may be your 5-in-1. If you have a heli still under warranty, call (don't write in email) Horizon Hobby tech folk. They will solve the problem.

It sounds like your heli has been doing this from day one. No crashes? No parts replaced? Have you tried popping the links off (one at a time) and polishing the balls with small pieces of brown paper bag (inside of links too)? Check the balls for plastic slag. Did you balance and track your flybar (yeah, i track my flybar). Check the hole of the flybar carefully,,..where the main shaft goes through,,..does it look elongated with a lot of play when you move it around...side to side etc.?? Good luck.

That is what is called the Pendulum Effect...nothing you can do about it. All 45degree flybared helis suffer from this..my 120sr and my msr does the same thing....have to fly around it.

A newbie question can the links actually get bent in such away they need replacing as I never bothered to look at them when checking over my heli and making my order?

It's not that they get bent. the holes get enlarged due to wear.

So they pass over the ball and that's the problem?

Never seen a bent one. As jake mentioned, the holes wear out, but this can be minimized by keeping them lubed well. I use silicone spray lube, but don't actually spray it on as it makes a mess with that much lube. I spray a shot in the garbage can, then touch the nozzle to the ball joints, leaving a small drip on the joint.
A bigger problem is losing the links in a crash. They pop of off pretty easy, and if it is in grass or such, they almost never can be found. It is good to have some on hand.

Cheers,
Kyle
