t-rex sa flybar ??????

[yfz450]

iam new to helis and need to know how to get more cyclk control/response my heli has the short fly bar do i need the long one or carbon fiber paddels iam lost it just feels like a slug to me too try a loop or roll.when in foward flight or hovering it feels fine p.s. since the pics i have moved the weights all the way in

[pitviper51]

iv put more positive expo on my belt cp to help with response.. lighter paddles will help to.

This may have nothing to do with your Heli and set up but it is worth mentioning just in case. I had a older model Trex clone (CDE) that used standard 9 gram servos and a generic ESC. The ESC was so generous with amps to the motor the servos got left out and didn't have enough power to move the controls well. I put on a BEC and seperate battery for the radio and got a huge difference. If your servos and power system aren't up to the task it will cause problems.

There are couple things to do. One would be to move the fly bar weights in or remove them all together. Another option would be to up the head speed. If both of these have been done I run some expo in the wrong direction (more sensitive). Hope that helps.

What is your headspeed??

On a Trex, if the head speed is too slow, it will fly like a pig

[Mudsurfer1234]

How much pitch are you running? Collective and cyclic...

Edit: Now that i looked at the picture, ditch the wheel collar weights on the flybar.

[exeter_acres]

Yep...I didn't look...but yep...lose them!


or is it loose

[yfz450]

thanks guys i did move the weights since the pics and for the pitch dont know i was talking to dennis at dee tee enterprise and he said that heli has the short fly bar which the dont make any more also said the all plastic head has to do with it also so i bought the se v2 it has a lonnger fly bar which he said would give more cylic control so i gess i will see.maybe iam just use to flying 3d plankers that are more snappy ?????????????????????????????????????????????????? ????????????

You can make this thing fly like a hummingbird on Crack. It just takes a bit of tweaking. Metal head, tight linkages, no slop, and high head speed. Make sure you dont OVERDRIVE the swash so it contacts the mast. This will rob head speed, and can end up popping links causing a crash.

Get a pitch gauge.... they are cheap and pretty much required for something like the TREX (or borrow one from a friend)

[yfz450]

i have a pitch gauge just have noy used it yet and noy really sure how

[adjonym]

The pitch gauge is quite simple to use. You just put it on the blade, set it to the "degrees" you want, or check existing pitch, simply by "eyeballing" the top of the pitch gauge with your flybar.
When the top of the pitch gauge is level with the flybar, you see the pitch degree on the pitch gauge. Simple as that.

It's mostly used to set zero pitch at 50% stick(for your basic setup. It also comes in handy to set your negative pitch for your "normal" pitch curve. If you are new to helis, you normally want your "normal" low pitch in the -1--2 degree range.
Hope that helps

2000 rpm head speed.-10+10 pitch as much throw as you can get out of your swash plate!! and hold on....

[bosshoss]

I know some would say 2000 is bit slow for 3D. I run a lot faster, close to 2800, give or take , depending on battery.

reaaally hold on then!!!
