I replaced the rotor hub and anti-rotation collar with cnc parts while chasing down power-robbing, tbe-inducing friction. They are the only non-stock parts in my "drive train", although I did also switch to the Xtreme bb motor. With these parts, a crack-free main shaft, properly gapped main gear and chopped, tracked and balanced blades my heli purrs like a kitten and flies smooth as glass.

I think there is confusion here that stems from the term you're using.. "Rx battery" because there are many RCs, usually larger gas/nitro ones, that use a separate dedicated battery to power the receiver (Rx) as opposed to it getting its power from something like a BEC (battery elimination circuit... which can be built into a ESC) ... OR, from the main battery in one way or another... like, in the example of the 120SR, directly via the 5in1 board where the receiver itself is also located.

... so, there are actually "Rx batteries", but they don't apply to the 120SR.

The old white label ones do and it's deserved in most cases. The higher C new generation blue/yellow label ones get recommended all the time... the small 1S ones I have are also cheap. I even have a video bookmarked somewhere of one delivering more power than an equivalent Hyperion.

I misspoke. Very sorry. I meant the anti-rotation collar. That part has the weak "fingers".
I have 5 spares in my kit.
If I ever run out of those, this will be the 1st non-oem part on my 120SR (aside from Hyp.550s and NT 600s).

It flies well in the basement (low and slow) and hovers steady as a rock but when it has more room, i.e. at the gym, fff is really tricky.
Ah well, there's plenty of Wednesday night and Saturday afternoon indoor flying days ahead...

I quickly tired of trying to bend those "fingers" back into shape after every couple of flights. As I recall the inner surfaces could also become rough; the extra friction was a source of tbe.

I never did replace the other collar in your picture; the plastic version seems to work just fine. But beware! If that collar is installed upside down it too will be a source of friction and tbe. There is a tiny ridge on one side that is supposed to ride on the upper bearing.

Maybe I was a bit unfair to the stock controller as I'm probably blaming it for a lot of my flying issues when really I was just/am not great on the sticks but the HP6DSM I was given made a massive difference. I found rotating with the stock tx, even when on the toned down mode extremely jerky.

I don't have one original part in one of my 120SRs apart from the main motor! That's not something I'm proud of by the way lol

So in this application would it be referred to as the 5in1 battery?

Does the RTF Tx have control adjustments that makes stick inputs more or less touchy?

Just 'the battery' is fine.

Yes. You can go between two modes by holding down the right stick so the light on the tx changes from constant to flashing. Flashing is less touchy and aimed at beginners.

120sr Weight Poll

Hey Guy's, Iam allways reading about people concerned about the weight of there birds so I thought I would start a weight poll. What does your RTF Bird weigh in grams? Please note if your bird is stock, also the battery.

I dont know what a stock 120sr RTF weight is. Mine has many mods, that being said my Bird with a 1300 mah battery comes in at 135 grams. I have plenty of power and she flies great. I have found that the extra weight makes her more stable. Also I have had her over a year, fly often and still using the original motors, main and tail.WS
