Impressive. Why don't you get another sim that would probably solve all that?

Is that the best you can do? This is precisely what I'm referring to when I indicate that you have your eyes closed!  I happen to feel that Reflex IS the best sim currently on the market (same as you). However, that will not force me to ignore problems I encounter and become blind-sided by update, after update, after update that continue to ignore these. So please try to keep an open mind and stop taking other folks' opinions so personal!

| 1. Heli models with low ground clearance and governor enabled sometimes crash at sim start. Creates confusion for a lot a folks. Workaround identified as requiring pitch to be set near 0 degrees.
++This is not a bug. This is the right simulation of what it does if it bounces into the gras at full negative load. Do this on the fenestrons. Why should this be a bug?
|
It is a bug when you consider that the crash occurs instantly when the simulation starts! How many real aircraft do you fly that go to max-rpm when you start them with radio in normal-mode and throttle at idle?

| 2. Minimum pitch for auto-rotation cannot be set below -8. Causes pitch curves to magically re-scale when you flip into hold. For example, model with -10/10 pitch, center pitch (0 deg) and flip hold, pitch changes to 1-2 deg. in sim
++Pitch works in the given limit. This is not a bug, this is a feature request. Watch what you are saying. If you don't use the reflex auto but throttle cut you have all the pitch you need. Again: feature request, no bug. Reflex does exactly what is says.
|
The BUG is not that the pitch fails to reach the assigned limit, but that Reflex incorrectly re-SCALES the pitch curve during hold, creating a different pitch curve than wanted. Again, with linear pitch going -10 to 10, (SwissKurt FYI, this means that at mid-stick, pitch is 0 degrees ), min-auto pitch at -8 (gets worse with lesser values), mid-stick in Reflex-hold becomes shifted several degrees:| Code |
| -10deg. 0deg. 10deg
NORMAL | --------------- | --------------- |
IN AUTO | ------------- | ------------- |
-8deg 1-2deg 10deg

| 3. Channel assignment and calibration window: NEED COMPLETE RE-WORK. Fails miserable on radios with throttle/pitch on same control, i.e. all Mode 2 radios with separate pitch channel. Configuring Gyro and hold create problems due to radio settings, e.g. hold usually changes throttle channel confusing Reflex. Impossible to accurately adjust max throws without major radio re-programming, i.e. disable throttle when adjusting pitch, etc.
++Your are right, it could need some rework to make it more clear. As it is today, the problem isn't the GUI but the complex structure of radio intelligence. As it is now, I can do all I want - it's complex but it's not impossible. If you don't get it, your radio programming knowledge needs some update. Again, not a bug, just a feature request.
|
It is broken! I can also do all I want with it since I know how it works and can get around it's quirks. However, I would rather not have to adjust radio programming to calibrate it with the software or have to explain to someone that just got the sim what a crummy radio setup system Reflex has!

| 4. Confusing V-Sync menu: most times you enable v-sync, FPS will be at the set monitor refresh and suddenly drop to 15-20 FPS ... unchecking V-Sync sometimes fixes problem.
++We have to differentiate: Problems with your understanding, driver problems and Reflex problems. VSYNC doesn't depend on reflex but on your video card drivers. No bug.
|
| Quote |
| 95% of the regular user never crossed with it because it works and their video card is able to run it. See the probs in here, all are solved by updating drivers and adjusting settings. In fact, Reflex doesn't do anything else a user can do going deep into his drivers. It's just a shortcut. Now try to explain to people like RCFan that it's a driver issue ...
|
You're correct, in most applications, VSYNC doesn't depend on the application, it's simply a switch for the gfx drivers. However, Reflex is doing something beyond setting vsync with their code, which is what may be resulting in what we're experiencing (what that is is unknown without source code or disassembling the binary, which I'm willing to undertake if necessary).
Most regular users don't have a clue on how v-sync works or that a problem may be a result of the setting being enabled! I am well-versed in driver issues (I've written and supported several drivers in the past for several device manufacturers ranging from SCSI, gfx, sound and other custom hardware across various platforms including Sun, both SPARC and Intel archs., Linux and Windoze, and developed under environments using OpenGL and DirectX).

| 5. Occasional problems with USB interface (black and blue). Reflex sometimes refuses to recognize interface. At times, disconneting USB from computer or (powered) hub, and reconnecting fixes problem, other times a reboot will only resolve the issue. Never have such problems with G3/G2 simulator Interlinks connected to same devices! It may be hardware conflicts, but have verified that problem still occurs when Reflex is only device on the USB (note, not connected to front ports, but on-board back ones or add-on USB2 PIC card)
++"Occasional" I only know of one issue beeing discussed here. Are you some kind of "Robin Hood", speaking out loud for the unknown mass?
|
Nope, I'm simply reporting a BUG I've encountered and the symptoms surrounding it. There is no way of properly explaining this (no logs or debugging capabilities to check things against), but I'm willing to work with Reflex to try to understand this problem further.
| Quote |
| 6. Many problems relating to engine physics, e.g. perception of low gravity making models appear to "float" more than real aircraft.
++ You were talking about "bugs". A little more precision would be needed here. I feel, that this "bug" is more understanding related. If I see it in relation to #11, I feel you really need another sim or finally learn how to fly.
|
This topic would require a post of its own. I'll be happy to start one and list all the issues I've encountered.

| 7. Most models are too sensitive to ground contact; where a real aircraft may bend and bounce a bit, even on some rough landings, Reflex always treats pilot to a crash.
++Can't get your point. Try better landings for a change instead of claiming bugs with a very funny approach. You can set sensitivity in the physical params. Come on, they give you the chance to modify the models, why don't you use it?
|
Goes directly to my point in item 11, thank you.
| Quote |
| 8. Inconsistent crash dynamics: sometimes a model simply stops (freezes) when it crashes while sometimes it performs a more natural roll/crunch.
++It resets if the crash is land based, it stops if the crash is tree based. That simple. Where is the "bug"?
|
The simulation is inconsistent; sometimes you see it happen on ground crashes and sometimes on scenery object hits. Granted, it's a minor bug, but I didn't try prioritizing the list in any way.

| 9. Incompatible radio interfaces; not properly documented. Forces users to take apart cable, (re)solder resistors and swap wires in hopes of getting a connection.
++At least they let you change wiring without loosing warranty. That the good point. The resoldering/resistor issue was an answer to an unknown or poorly reserched signal specification. Did you know that reflex is offering 12 different adapters? If someone is to blame here, it's the radio manufacturing comminity, inventing new socket every few weeks. Did you read that Futaba 7C story here? Futaba is not even up to their own standards. Get a student cable for the 7C from you LHS and check the plug. Come back here if you can answer that question instead of blaming others.
|
What happens to folks that use different-brand radios, do they need to obtain separate interaces for each one? Reflex needs to be up to speed with the market on this aspect since they require customers use their own radios. Why is it that other sim manufacturers don't have these problems with their interfaces; all they need is the right cable extension for their radio, plug that to their interface and voila! Reflex has a bad reputation when it comes to radio support because of this. The developer should take a step back and re-design the whole thing as necessary.

| 10. Simultator takes over CPU even on high-powered systems. Lowering priority level of the sim relinquishes some of the CPU and sim still runs acceptably well.
++Again, where is the bug? It's the programmers decision for technical reasons. Does it fail on a computer? Do you have limitations using the Reflex? Does it fail in function? Where is the bug?
|
Programmers make mistakes ... LOTS OF THEM. Runaway processes and loops are common mistakes in programming; sometimes poor/bad programming habits cause these problems, e.g. lack of better way of coding certain things. The bug is that the sim should only take as much as it NEEDS to perform its function. My recommendation would be to perform profiling on the Reflex code and try to reduce CPU consumption whereever possible.
| Quote |
| 11. Most stock models fly poorly or unrealistically requiring hours of parameter tweaking.
++ commented already.
|
Indeed, thanks again!

| The siliconians I know are rather pale with black eye areas working real hard to provide products that stand up to users like RCFan and you can clearly see that you can never satisfy him.
|
That is a fact, but it's not relevant to the topic at hand. Customers are just that and can never be satisfied. They are neither right, nor wrong ... THEY ARE SIMPLY THE CUSTOMERS that help pay the vendor's bills.

| By the way, I don't believe he ever paid something for the updates so he is nagging on things he took for free anyway.
|
I own two copies of Reflex. It's Reflex's own policy to distribute updates for free and encourage customers to support their development effort as WE see fit, based on the improvements obtained. You have no right to question my integrity since it's their policy; if you don't like it, that's tough. I'm sure if Reflex considered their policy was wrong they would go immediately back on their word and start charging for updates. |
