That sounds about right for the pitch.Are you using a gov or throttle curve? If you are using throttle curve try going to your throttle mix menu and put in 30% + and - throttle to elevator and the same for throttle to aileron mix then make sure in stunt mode when you give elevator or aileron input you will see the throttle move on its own giving extra throttle when you give cyclic this should help with the bogging.
What radio you using I no JR but 2.4 or 72mhz ?
With the XP9303 the throttle mix is below the gyro gain in the menu

You're most likely using too much collective. Practice using less and use more elevator.

Thanx Tarzan_, i`ve got a gov on, head speed at 90%(+-2000rpm)
, using jr dsx9 2.4, also fitted the carbsmart of csm @120deg,got SAB 600mm blades on, thought that i might`v over cooked it on the pitch gauge, would it help to set the pitch curve say from 10% to 90% (less curve) in stunt 2? or should I just use less cyclic/collective?, sorry. know this sounds stupid, but I`m relatively new to 3D. thanx again

Well then you just need to practice collective management like

+-10 is fine, if you're new at 3D, you might tone it down to +-9. Keep your pitch curve 0-100. Use your swash mix menu to tone down the overall pitch.
You might also want to get more headspeed, 2100 would be ideal. Less collective on the sticks is better

Not sure that makes sense. You can't set the pitch curve from 10% to 90%. It's generally at least a 3 point curve, so you should have 3 numbers there at least. Not just one.

If your pitch curve was set at 10% currently across the board, your pitch would never change when you move the stick up and down.

Either way, if you're starting 3d 10 degrees is just fine. If you find you don't have enough you can add more, but adding more collective certainly won't help you bog less. It'll help you bog more unless you're good at moderating your inputs (collective management), which apparently you aren't yet - so I'd say no, leave it at 10 degrees like you have now.

Like the other guys have said, you're just giving too much collective when doing tic-tocs. They aren't the same as doing 'em in the sim, so it'll take you some time to adjust and get a feel for how much collective you can give without bogging things down.

Hope that helps.

If it can't hover, it ain't worth flying.

Try doing small rainbows instead of tight tictocs I mean do a tictoc but stop briefly inverted and upright then apply collective so you get used to how much collective you need to send it back and forth. You can lower your pitch but I would just try to get used to + - 10 if I were you. It will come just keep at it

how much cyclic pitch are you running? reduce your swash mixing for ail and ele down to say 45%-50% - around 7-8 deg cyclic. I would suggest leaving collective somewhere in the 10-11 deg. range and learn not to hit full collective. Sounds like it may be too much cyclic (elevator input specifically) on the tic-toc's.

Have to agree with jschenck, leave the pitch as it is and lower you cyclic.

You do the mixing on your radio.
What kind of radio you're using?

I'm a Futaba guy, so now we need to wait 'til someone tells you how to do your setting on the JR radio i'm not sure how you get into the swash menu in JR

I have the Phoenix sim. In the edit menu i crank up the induced cyclic power loss. This realy helps in making it feel much more real.

Like everyone said,you have to learn collective management.If your trying to bang tictocs really fast you'll bog the crap out of it.Watch how easy I was on collective in the start of my video,no bogging at all.Then watch the end,I banged some really fast tictocs and bogged the crap out of it.Im running 2150 headspeed,11 1/2 degrees of pitch and 8 degrees of cyclic..Also what main blades are you useing?Main blades play a BIG part in how the heli reacts to bogging.I had a set of MAH CF blades in this video which I really liked but I had to be easy on collective or the heli would bog pretty good.Radix and Mavrikk G5 pro wide cores are the best blades I tryed and don't really bog at all unless im trying too..

Go into your Swash mix and adjust Aile and Elev for cyclic.You adjust cyclic the same way you set the pitch up.Put your left stick (pitch/throttle stick) at center so the mains are "0" .With the main blades to the front of the heli,move Aile (right stick) all the way to the left or right and adjust the Aile numbers in the swash mix.With the main blades to the side of the heli,move the Elev (right stick) all the way to the top or bottom and adjust the Elev numbers in the swash mix.
