Beast X and TRex 450 Pro. Like flying a wet sock.

[bikerflier]

I had a TRex 450 Pro with BeastX that was amazing.
Fantastic flicks, rolls and piro's as fast as I have ever seen.
It died so I got another.
It's like flying a wet sock.
Slow flicks, rolls and piro's.
Only differences are first one had MKS 95DS servos and Futaba/Orange HS receiver with Curtis blades.
New one is standard Align servos, blades and standard Futaba 617FS receiver.
New one has tail bounce which I can't program out, is totally lethargic and a complete let down.
What oh what is wrong.
Have reset several times, have 12 deg +/- collective and have tried full cyclic circle as well as setting down to 10 deg cyclic.
Any ideas before I bin it.

Don't you only need to setup 6 deg's and then a swash limit.
Limit being until swash bines?
Are you running expo?

Yes, set the 6 deg and then the swash limits so that I get 12 deg of collective.
No expo.
The limit is for cyclic with no binding. Have tried full limits and also limited so that only 10 deg cyclic.
Whats annoying is that first heli setup so easily first time and was truly amazing, never had a heli so responsive, it was a true pleasure.
This ones a damp squid.

Which mode are you using?
I just jumped from sport to transmitter and made my 550 a lot more alive.
But I liked the sport feel. For me felt more like a flybared model.
I hope to be able to get it close to sport but from the transmitter.
I like the idea of being able to change things with out the parameters on the model.

If you haven't already in parameters B" set to radio, idle up throttle mines 100% flat line.

Weird. Got rid of my BeastX but it was certainly lively! I was using Extreme cyclic response and it was very aggressive (too much so in fact). Also, have you adjust the pots at all?

[waveydavey]

Are you setting up with expo active? What mode/flying characteristic are you using? You don't limit cyclic the Beast will do this depending on what mode your using. The tail bounce where is the pot for tail dynamic, where are the pots for cyclic gain and cyclic dynamic

I'm just using Sport mode.
I was thinking though that the first one was second hand and was maybe in a different mode.
I'll try that next and also Transmitter mode, I would prefer some of the setups on the transmitter.
Got to get rid of the tail 'bob' first though.

Thanks, I will try that.
Throttle curve is 10% higher than I had with the first one and the first one was amazing performance.
100,85,100
Really stumped.
I will also write to Stefan at BeastX today, he's very helpful.

Yeah in Sports mode your cyclics will be very tame regardless of limits. You can try Extreme mode or transmitter mode and see which one you like. Now if they would just fix the tail issues in V3!

Pot 1, I reduced quite a bit as I think this is supposed to be the one to control the bounce. Half way between arrow and zero.
Other 2 I tried a little up and also a little down.
Still early learning, but as I read and reply to posts I am thinking more that the performance could be due to the mode.
Thought I had the other one set to Sport but can't remember.
Tail bob is the pain though.
All linkages are nice, no binding, it's a new heli so I'm assuming all the parts are good, but you never know.
Hope I don't have to start chasing mechanical problems as well.

I think it might be worth checking the settings in the speed controler
On Align speed controls you used to have set how much stick moveement you have on the throttle.
I see you are using Futaba so might be set for a Jr style pulse width.


Also Tail might be different in transmitter mode?
good luck

Hi
Got this heli from Rob at Southwest Helis, one he had built and couple of setup flights.
I am beginning to think the response is due to being Sport setting. I will try Pro and Extreme when this blasted wind stops.
Why the tail 'bob' I don't know, so don't know what to look at or adjust.
Never seen anything in Align instructions about setting the ESC throttle travel. Never done on any I have had. Don't know where to find this sort of instruction, setup.

If you've got pot 1 lower than normal that why it's sluggish. Coupled with the expo introduced by the sport mode this is defo where your problem lies. Put the pot to centre and also pot 2. Switch the control behaviour to transmitter. Add a little expo if you need to and try this. Pot 3 is where you want to be for the bounce on the tail. I'd start off with it at 0 and get the gain up to where you can get it without bounce. Leave the heading hold value where it is as normal and adjust until you instigate a wag. Back off slightly and then check your stops. If it's bouncing turn pot 3 down slightly.

Not being funny but have you got the instructions? If not they are available for download from the BeastX forum, also watch the setup video posted on the forum. Its good for initial values.

Just check the Esc settings on page 25 of the manual below
I think it would be worth doing as I know the model was used on a Dx 8
