The 3.7v 1000 mah 15C battery and holder.
The weight of the 120 sr with the led lights blinker board and wireing and new battery tray installed but without a battery weighs 100.0 grams..right on the money..lol

So with the 1000 mah battery the total AUW is 128.4 grams.
It hovers at half stick and has plenty of climb power.
The increased headspeed makes flying this heli much better in some wind.
I'll use the single stock 500 mah for inside and the 1000 mah for outside.

On to the pics.......

Excellent Job Ridge! Thanks for the instructions

They are in Florida

Have a look under the CX2 mods section of their site - sold singly

Found 'em @ slickzero, thanks!

Just tried it tonight, she would not even lift of the ground. Sure my heli is heavy but the stock motor has no problem handling the extra payload. Not sure why? It seemed like a good idea anyway, but it sure was a pain in the as swapping those pinions, glad thats over.Im sure its just a matter of time before there is a brushless upgrade (fingers crossed) available, with the 120 SR there is a lot more possible upgrades over the mSR.

the Xtreme 180 Se is that much heavier or something else was wrong?

Just a thought but wont the motor you choose be important - the 180 comes in left and right rotation - if you have the wrong one fitted it will be gutless in reverse.

Subscribed. Just got mine...and lovin' it!

Perhaps - not sure if its just a reverse polarity thing with plugs or not.

the 180 is normally used with 7.4 volts, but if the SR 120 has the same motor as say the cx series coax's then I dont see why it wouldnt work, UNLESS... the 180 SE needs 7.4 volts.

I've had my new 120 SR for almost a week and so far, so good, 26 flights with no issues. I've owned the CX, CX2, MCX and MSR and was not really pleased with the performance and durability of any of those models and ended up selling them. I'm glad I bit the bullet to chance a try with another Eflite product, the 120 is a keeper! I've only crashed it once, a 10' drop onto the kitchen tile floor and thought, "well, that's it.....destroyed!" To my surprise, not even a scratch! I also own a Hirobo SRB Quark that I love dearly, but this little gem comes in a very close second as far as performance and trouble free maintenance goes. The 120 tail holds better than the Quark, a click or two of rudder trim (during the 7 minute flights I'm getting) results in a rock solid hold.
If you're on the fence as far as thinking about buying one, don't hesitate, do it. You won't be disappointed!

Um....not sure sure what a '180' actually is, but the SR120 donk is a pretty big mean mofo for a brushed single cell.

Reminds me of the old 'D9' motors that were the beez-neez in slot-car racing many many moons ago...

Yep

They're a pretty fine Bird to fly.

My route was a Micro Twister co-ax, the mSR, and now the SR120.

The Micro Twister was the first thing I ever got up in the air and actually had fun with. I was trying to fly planks solo with not a lot of success, but the MT co-ax gave me some confidence. I stacked it, busted it a few times, and learnt heaps along the way regarding fixing your own things. And I can't believe I used to get sweaty palms while learning to fly it. Now, it's basically just set and forget - up she comes, do a few laps, and put her down again.

Then came the mSR, and it was a darn handful to start with, but now it's like an extension of my body. I don't get too fancy with it, but I enjoy walking it around the house - through doorways, up and down the staircase, and generally making up my own 'laps' as I go. I've flown it outdoors, but in stock configuration, it really hates any hint of breeze outdoors.

Now onto the SR120. A bit daunting to start with - bigger Bird, bigger noise, bigger crash. But I've just been downstairs and had another fly of it just now - half-cut and all. And I loved it. Our weather has been pretty suss down here for nigh on 2 months now, so it's all indoor stuff around the house. Sometimes I still get out of shape, but my learning is at the stage of anticipating where it's heading, and what I have to do to get out of it. Tonight I just did some simple stuff, and did half a dozen nice hands-free hovers. "Poco a poco". Baby-steps I 'spose, but what a great feeling to have that feeling that you're in control (for a change).

I realise that flying my CP 450 competently is a fair way off yet - so the 120 fills that gap nicely – a great stepping-stone IMHO...

All of these praises of this " Eflite crap" can't be right. The story to begin with was that it was a bigger mSR without a market to buy it. WELL, I guess he was wrong! I haven't flown a Quark, but I love my 120 even with its brushed tail motor that hasn't given me any problems at all. Now they could develope something a little larger FBL with a 3d gyro.

It sure does,i'm in the same boat as you !
