Royal Evo Concerns - 12/23/2003 7:31:11 AM

Status: offline 		I'm a little worried about two aspects of my new Royal Evo 12 and am hoping there will be a firmware update to correct these issues.

1) It appears that expo is not changable with either dual rates or flight modes. This needs to be corrected for folks who fly both 3D and IMAC... switchable expo is a neccessity. Even my 8103 does that!

2) When switching flight modes, the radio does this "soft" transition. During this 1 second transition, the pilot has little to no control over the aircraft. Unacceptable with fast airplanes, and it creates problems when flight modes are required to be changed on down lines, during rolls, etc.... on any airplane.

Any input/correction is appreciated.

Thanks,
Jason

Status: offline 		I agree. My Mpx 4000 has expo setting for each flight mode and it is essential when switching between pattern and 3D modes - approx 30% in pattern but as much as 90% expo in 3D. The 4000 has user defined rate of mode change, I always leave it at instant change. Evo's phases are rate switches with a trim setting, that is not enough to satisfy today's demands on flight modes. If it can be done, I urge Mpx to upgrade this soon.

Status: offline 		HHHMMMMM This is the first non positive post of the evo that I've seen so far. Is there any work around or fix for this in the works? has anyone else out there had any problems or quirks with their evo?

Status: offline 		Not that I've found. The most knowledgeable guy I found (who had all these other programming tricks figured out) said we are stuck with a single expo per axis regardless of flight mode or d/r setting. I haven't surfed the huge Royal Evo threads, but I've seen no mention of the loss of control during the soft flight mode transition. I'd rather have it be an instant transition and maintain control... the soft deal is a gimmick anyway.

These really need to be fixed. I'm NOT going to move to a 4000 to fix such elementary problems. I know a (nameless) guy sponsored by Hitec who won't switch to the Royal Evo because of these deals... if they fix them he will probably switch.

There is no fix until the software is updated, and maybe not even then if MPX chooses not to change anything about this issue.
With that in mind, and since that means that you do NOT want to take the EVO you have ordered, please mail me by PM and I would like to take the one you have ordered.

Thanks,
Highflight

Status: offline 		Why don't they use the software from the 4000? Isn't it supposed to be the best?

I would like buy one of these radios, but only after it works better than my 8103 for average precision/3D flying. Otherwise, what's the point?

I bought a Polk radio based on it's advertising as being the best. It is the cheapest feeling radio I have ever used and the programming is lame. Nothing has been done to address the problems. But it only cost $275.00 with 8 channel synth receiver.

Status: offline 		Great... thanks Mike. Are you looking at the issue of loss of control while switching flight modes too?

Thanks again,
Jason

Status: offline 		Try switching to 3D rate and initiating a wall at the the same time... there will be a 1 second delay before the plane responds. The pucker factor is a little higher when something like this happens on a down line.

Basically, during the one second soft transition between flight modes, my radio ignores pilot input until the transition is complete. Maybe I got a bum radio, but that's what happens.

Status: offline 		I'm not seeing the same effect. To test it I programmed an elevator for 20% travel in phase 1 and 100% travel in phase 2.

If I hold on full up elevator first and then switch to phase 2, elevator moves from 20 to 100% in the time of the soft transition which, subjectively, feels much less than the second quoted in the manual. The elevator moves all through that time, it does not wait at 20% until the end of the transition and then jump to 100%.

If I pull back as I move the phase switch the ele goes immediately to the 20% point and then from there follows the soft transition to 100%.

If I switch to phase 2 and pull back a fraction of a second after the phase switch I get immediate 100% ele that seems to be faster than if I had held on ele first and then done the phase switch.

At no point during the phase transition do the servos stop responding to movement of the controls.

The transition is over so quickly that I leave just a fraction of second gap between making the phase switch and then applying full up ele, the ele goes to full travel instantly. I don't have to wait anything like a full second for the soft transition to have completed before I get full ele response. The only time it moves slowly is if it is applied before, or at the same time as the phase switch is made. For most people this would be unnoticeable but I do realise that 3d stuff like parachutes and walls need instant full travel. I get this with a tiny wait between phase switch and applying the control. I haven't tried flying it with the Evo since I use a 4000 but I can't see I would be bothered with that tiny fraction of a second wait especially as I would have switched phase once the downline was established and not wait until the instant that I wanted to do the parachute or whatever. In reality I switch my Synergy to 3D phase and leave it there for much of the session, I don't switch it on and off per manouevre but that's because the 4000 allows expo per phase so I can afford to have 90% expo dialled in during 3d phase. I do agree, as I said before, that expo per phase and the option of an instant phase transition should be added as soon as possible. But I am not seeing anything I would call a loss of control.

Status: offline 		That's wierd.... mine behaves slightly differently. But, like you say, it isn't really cause for actual loss of control of the airplane, especially with proper planning. I was just trying to do dumb things at dumb times.

They DO need to fix the expo, though. For me to keep flying this radio it WILL have at least the functionality of an 8103.

Cheers,
Jason

Status: offline 		I was so sure that the elevator on mine was going much faster than the soft phase switch that I have done a little experimant and proved it - I did it with the elevator but it applies to any control that is moved while the soft transition is in progress.

The soft phase switch takes approx 1 second according to the manual. Subjectively I feel it is less than that. Anyway, if a control is moved once the phase transition has already started, that control ignores the phase transition and goes straight to the new phase, without taking part in the soft transition. This means that if you move the phase switch to 3D phase and then after that you pull full up elevator you instantly get 3D phase elevator travel (or whatever control you moved) even while all the other controls are still moving through the soft transition. For example, in normal phase put on full elevator then switch to 3D phase and then immediately put on full aileron. The elevator will travel at the transition speed because it was applied before the phase switch but the aileron will instantly go to full 3D travel even while the elevator or other controls are still in transition.

If you are getting the soft transition of the elevator when switching to 3d phase it is because you are moving the elevator control fractionally before or at the same time as you move the phase switch. As long as you move the phase switch fractionally before you start to move the elevator stick you will get instant 3d phase travel without waiting for the soft transition to work through.

You can prove this to your own satisfaction using the servo monitor screen. Set the flap control fixed value to Off for the normal phase and 100% for the 3D phase and assign a servo to flap. In the monitor screen you will see it travel through the soft transition time. Hold on elevator before moving the phase switch and see the elevator travel at the same reduced speed as the flap. Now move the phase switch first and then promptly move the elevator stick, the elevator servo goes straight to 100% travel at full speed, overtaking the flaps which are still going through the phase transition. You need to be quick and get your timing right to see it, but it is most distinctive and definitely there.

I wouldn't call the lack of expo per phase a killer or in any way giving the Evo a functionality below an 8103, the Evo can do so much much more than an 8103, I would still choose an Evo over any Asian radio, but each to his own.

Status: offline 		Another point to add to what Harry says is that, over time, user input to MPX may very well result in changes being made to future software upgrades to the EVO that users can download off the internet and perform the upgrade themselves (for free). MPX has already done this with the Profi 4000, and in fact, there have already been a couple tweaking upgrades to the EVO with one notable example being that the US software is (will soon have) receiver shift selectability in the software. This upgrade will cost NOTHING for the EVO while NONE of the Asian companies are offering a "free" upgrade to any of their non-shift radios to become shift capable FOR FREE!

You will NEVER see the software for the 8103 changed in any way for the radio you hold in your hands. What typically happens with Asian radio companies is that they will "declare" a radio obselete and then bring out a new model to replace it's predecessor. Even if they change features on future 8103's, YOU will not be able to upgrade the radio that you already paid big $'s for.

So, cost of upgrading the EVO to new features? Zero
Cost of upgrading the 8103? A few hundred $ to replace the entire radio with a new model.
