possibly silly question

On Phoenix, a Trex450SEV2 is almost unflyable with the controls that my actual heli has been set up to use. The heli has been setup and posted to me, and I'm not experienced/brave enough(yet) to fly it.

I have set up a "new" model on my dx6i and it's stable as can be in Phoenix.

I've done all the calibration stuff, so am pretty sure that's not the problem.

So basically, my question is: Would the fact that a simulator is unflyable translate to my actual heli in real life? So far all I've done is spin up the rotors to less than take off speed and I'm a little nervous as it starts to creep around the floor before it's taken off in a similar fashion to the simulator.

Hi, it's worth knowing that the model that's been setup on your TX is very specific to your actual model and takes into account the way that it's been setup, the config of your servos, the linkage lengths and everything else.

The models on pheonix are best case scenario setups, everything is perfect with no imbalance, perfect zero pitch at mid-servo travel and perfect centre of gravity.

therefore there's going be be a huge difference in the way that the radio handles your model to the way in which Pheonix expects to be handled hence the reason for the need for a different model memory.

There's a good chance, dependent upon how good the setup is on your own model, that it will fly in real life in a similar fashion to the 'stable' other model memory on your tx whilst on Pheonix. If it doesn't and you've parted with cash to have it set-up then there's a problem...

thanks for that, kind of sets my mind a rest a bit
Will hopefully have a bit of a test fly this afternoon (if I can get out of work!)

What settings are you using on Phoenix? You haven't got ccpm enabled on your radio have you (for Phoenix that is)? As far as I can see, the only way a heli won't be flyable on phoenix is if you've changed the heli settings, not the radio settings, other than the ccpm setting.

will have a look later Murph. I just plugged the dx6i straight in using the Model 1 (which apparently has been test flown on my trex450) and I can't even get it off the ground without it hitting the blades (normally to the left). However I created a new model (model 2) and simply set it as a heli and have not touched any other settings, and it fly's beautifully.

That sounds about right, your heli settings for the trex will have a ccpm setting, which needs to be disabled for Phoenix. The default on the dx6i is ccpm disabled, so thats why it flies ok on a different model setting!

phew, thank christ for that. Odd why Phoenix treats a simulated heli different to the real thing...
