Hi,

How to Properly Set Up the Spektrum DX6i Transmitter with Phoenix Flight Simulator

Ok, I've read the thread, some nice info. But nothing really to tackle one remaining problem I'm having. Got some serious left drift and switching models or using trim seems to help. Not necessarily looking for hands-off hovering, but the accelerated drifting to the left is telling me I might be missing something. Hopefully someone can tell me what it is, or what parameters to explore for a fix. Thanks!

Run the transmitter calibration again and make sure you follow the instructions to the letter.

Greetings all,

Just a quick inquiry - with the JR XG7 there appears to be a slight error when in idle up mode; in a normal hover the throttle stick is 2 marks below the center stick position, but when I am inverted the throttle is more or less right on the center position. I used to use a DX7 with Phoenix 2.5 and it used to behave as expected; i.e. whilst hovering inverted the throttle stick position would be virtually a mirror of an upright hover - 2 marks or notches above the center line. Has anyone else experienced this behavior, and is there a quick fix?

Thanks,
Carl

Honestly I don't think there is anything that needs to be fixed? Are you still flying Phoenix 2.5? ...or Phoenix 4? What heli model are you flying? Is this behavior the same with all helis? ...or just a specific one?

There can be several reasons for asymmetrical thrust behavior, from the blade pitch setup on the heli model, to your end points, swash mix, travel adjust, pitch and throttle curves, etc., in the transmitter.

What kind of setup are you running in the JR? All defaults, all 100%, no trims, etc? Straight, plain curves?

Perhaps your observation does indicate something, but I'm not even sure I've heard of anyone even noticing such a thing, or feeling the need to fix it. But we'll try to help. Also, you might want to post in the main Phoenix section which will let you add an eye-catching title for better response.

Did you recalibrate the sim with the new transmitter? If not, that's likely your problem.

supermofo · 04-23-2013, 12:31 PM

Hey Rojack,

Thanks for your reply! Quick bit of background - I've been out of the heli game for about 2 years, in fact Alan (aka the Bum) helped me with a few tips on setting up my (now deceased...hence the heli break) Compass 3D Plus...last used Phoenix when it was on version 2.5 but recently upgraded. From memory, and as is the case with all the CCPM helis I've flown, inverted used to behave as described previously. Since the upgrade to V4, and since I changed from a DX7 to the XG7, this strange inverted behaviour has appeared.

To answer your questions: 100% defaults, straight curves, no trims, and yes it happens with all the heli models I've used in Phoenix. I've even tried to compensate for this behaviour by adjusting the curves in the radio, adjusting the curves in Phoenix, changing the mid stick pitch angle in Phoenix to a positive/ negative value...I've tried everything! Recalibrating, setting up a fresh custom radio...nothing seems to alter the 'inverted hover at mid stick' thing. Even my current heli, a humble Blade 450 3D hovers inverted at about 1.5 notches from mid stick. Stumped!!

The only thing I haven't tried is reinstalling V2.5 to see if the inverted strangeness occurs then...in which case it must be something with this radio. I'll try this experiment and report back..

Cheers,
Carl

..Tried re-installing V2.5 and the mysterious inverted anomaly remains...
Back to the drawing board!

Cheers

supermofo · 04-27-2013, 05:05 PM

Finally, got this inverted thing sorted - just added 30 'subtrims' in the pitch channel of the radio...upright and inverted balanced!

Cheers

supermofo · 05-01-2013, 06:09 AM

I really screwed up with this whole inverted thing...even after the last 'experiment' the sim just wasn't behaving as I remembered it to from 2.5 (I've been asking myself for the last month or so since I started flying again, 'damn, have I really lost all my skills in just 2 years?!) Apparently not...
Well to cut a long story short, the mistake I'd been making was to calibrate the radio in Phoenix whilst I had pitch/ throttle curves already programmed in, so the 'endpoints' for these channels were always going to be false...leading to this strange inverted behavior! The monitor screen in the radio told me all I needed to know.
So apologies for admitting to following the OP's instructions at the beginning of this thread, and for admitting to having straight curves, no trims etc on the Tx...maybe some will benefit from my stupidity

Cheers,
Carl

Trying to setup my dx6i, why set travel adjust to 125%? I thought we are suppose to setup throttle curve/pitch and other adjusts on PH Flight SIM and not radio. I started reading this posting and it looks like we are suppose to set thrim and all curves to linear?

I have no idea why 125% travel setting on the Tx would be useful in Phoenix, other than maybe it *might* give you a little more resolution. I've found the resolution just fine at 100% with my DX7, but then maybe a pro-flier could feel the difference more than I could.

Phoenix is going to scale whatever you send it anyway, it's not like you are getting any more "travel" out of the virtual servos... As soon you as you do a calibration, full stick deflection, whatever number the Tx sends to Phoenix, whether it be 70 or 125, is going to be 100% inside Phoenix.

Anyway, I, and I'm sure plenty of other folks use 100% travel adjust and are quite happy with it, so worry not my friend. Feel free to leave the travel at the default 100%.
