T-REX 600N
Trex 600 Pitch Range

Hi There,

Got a slight issue with regards to pitch range,

I'm wanting to run -+13 or 14 with around 9 Degrees cyclic, But I'm only able to get 10 -+ with 8 Degrees cyclic before the swashplate starts to bind badly on the top bearing block,

So, I either run a little bit more pitch to sacrifice cyclic or run -+10 on the Collective so get a bit more cyclic, even that at 8 cyclic it binds a little on the top bearing block, But i don't mind that little bit.

My head setup is pretty much spot on (I think) with regards to linkage lengths and geometry,

Any help would be appreciated

Regards
Callum

You may have to drop the swash plate down at center stick, shorten links, and strart setup over.

Fly with scheduled ground contact !

You probably need to go FBL.

like bert said on the other forum, make sure your swash plate is centered in its pitch travel. ie if its binding a ton at the bottom and none at the top, move it up more till it binds just a tiny bit at the top and the bottom.

if you still cant get what you want, buy a quick uk swash and you will be able to get 13.5 and 9 no problem.

you will have to drop the swash down and reset the head linkages if you want that much pitch, but you will struggle to get that swash angle with out it binding. why do you want that kind of swash and pitch movement i have +-10 on pitch and 7 on swash all good!!

10 and 7 is fine for sport flight, but no good for 3D. I run over 13 and 8 on all my helis.

I am running 11 pitch and 8 cyclic for 3D. I am happy with this setting.

some people are happy running 11 or 12 for 3D, but you can't get those hard stops that you need for "smack" style flying, you also won't get as much speed when you bring the disc vertical and go to full collective,like when your doing "frog hops" the manuever thats like a horizontal ticktock.

My equipment (engine and servos) is not capable of supporting 13 collective and 9 cyclic. It will definitely bog the engine down for cyclic demanding maneuver of any kind. Also, how can you set to that high value with no binding at all for a flybar head? The maximum I can go is 12 collective and 8.5 cyclic, and with that setting, I can see the head starts to bind.

the stock trex 600 with only 1 upgrade (quick UK swashplate) is capable of supporting at least 13 and 8 with no binding as long as you use either an electronic or mechanical swash ring on your radio.

of course the engine will bog, thats what your thumbs are for. its called collective management. quick burst of 13 or 14 deg of collective and 8 cyclic for less than a tenth of a second to do hard stops will not bog the engine. neither will 14 degrees collective with no cyclic for a vertical disc pushout.

here is a great example of great collective management and great smack style flying. I think colin runs 15deg on his raptors.

http://www.youtube.com/watch?v=47UKkVNLy8c 4:07 is a great example of a full pitch pushout.

Why dont you check out helifreak,bobs video trex 600 set up ,the problem i had was the pins hit the swash plate if you have put in full collective and then add cyclic,his video helped

What LovemyTrex said in his previous reply, second paragraph, hit the nail on the head.

Of course you could raise your head speed and use less pitch. I run 13,8 or even 9, mine binds slightly at full + or - and full elevator or aileron but never use both extremes combined in flight.

60% of the time, it works every time!

when i had trex 600s i ran 11 pitch and 8 cyclic with os 50 this was the limit before bad bogging.some run loads of pitch you dont really need it but if you do a cyclic ring is a good idea.try 10 pitch and 9 cyclic.as for flybarless dont know about the 600 but my 700 pulls 12 and 12 no probs.
