Might have more to do with coming off the throttle just at the right time...??

My 120 SR does seem fairly finicky on take offs and landings as well. One very strange thing is that on slow to moderate take offs it ALWAYS wants to pitch heavily forward, regardless of COG or trim adjustments. Does anyone know why this is happening?

I know ridgewalker and others have used grommets or tubing bits of sorts for more grip. I'm just using it as a challenge to study the heli so I can learn what's required with stick movements to counter these things.

I've also been having fun with the orientation/hover training mode on Real Flight 5 and it's helped me out a lot even though the default heli they use is a large CP heli. This has even helped breathe new life into flying my MSR. When I first started flying it I just though it was an inevitable spastic trait that could not be tamed during take offs and landing. I've been practicing a lot with spot landings and controlled (almost vertical) launches and even landed the MSR on top of a Pringles can..... once. The Quaker Oats can was becoming too easy.

Anyhow having lots of fun flying, quirks and all.

How do you get a good measure of time on batteries? Do you let the heli run until it starts losing power?

Set a timer on the TX is the best way, also using a voltage-meter is a must.

I agree with Kris re timer, (I set mine to 6 minutes)
Also a tip from the good lads here to not discharge the battery any more after the red led sttarts flashing on the heli.
I have a voltmeter but would probably short the pins out trying to use it

There are also some good articles on this site re care and usage under "Batteries and Chargers" on theese new fangled lithium polymer batteries.

Xheli has a different brand and is out of stock.

I guess what I should have said was, where is the best place to buy the Raiden brand batteries that you all are referring? I would also prefer a vendor/company that is in the US and has them in stock.

I don't want someone to tell me the answer, I'm looking to you experience members who have been in the hobby for some time to pass on some of that knowledge. I'm brand new to the hobby and would like to avoid purchasing the wrong products or using a vendor that isn't reliable.

Thanks for the help and I'll stick to using the search feature around here.

Din you see the lil wink at the end of the post?

Yep...mine want's to lurch forward on take-offs to - I give it a fair handful of back-stick on lift-off.

And I don't have a lot of success in slow take-offs. I do a lot better just punching it up in the air - much the same as I do with the mSR. Just give it full throttle with a good pull-back on the elevator, and she comes up ok. After that, it seems to fly fine...

I'm still on the short-balls, and will probably fly indoors on them - it's got plenty of movement inside with just the short links.

Bit daunting inside, huh? And how's the sound of that main rotor? Sounds like a Helo, huh?

Ditto PITA on plugging the battery in. But I do the same thing on the SR120 as I do in my mSR - always plug the battery in with the battery outside of the bird. Then wait till the light comes on (gyro has stabilised), and finally slide the battery into it's holder.
