OK, a funny question popped up at the swap meet today. A guy was selling his G3 because he was buying a G4 from one of the vendors.

The guy buying the used G3 was told that he would not be able to register his purchase until the original owner "un-registered". Strange concept....... I've never heard of un-registering anything. And it appears that the online RealFlight regiatration system has no such thing as an unregistering capability.

Has anyone registered a previously registered (by someone else) G2, or G3?

I doubt seriously that Great Planes would sell something to their customers that would have no resale value. But stranger things have happened. Anybody regiestered a used one?????????????

Yes, i've done it a few times now (with G2, G3 and G3.5).

All you do is send Realflight's tech support an email asking them to clear the registration so that the new owner can re-register it in his/her own name. In each case Realflight responded within 1 business day and it was done.

If you don't go through this process the new owner will not be able to download online updates and will be stuck with whatever version is on the CD.

I have legitimate questions about registration- do you have to register at all online? And, can I move RF around on several computers without resorting to trickery? I'm about to start teaching a course at the university on building and flying rc. I'm buying 5 RF G4 sets. I'll have to get used to it before the fly class starts, and I'll do that in my office or here at home. Later, once I know what to write for the students handouts, I'll install all 5 on computers in their lab. I really don't want to go through hassles in getting the job done. I'm sure that the students will be on computers that aren't hooked up to the Internet.

Well my experience indicates that RF only works on one computer unless the hardware on another computer is nearly identical once it's registered.

Yes I had to get KE to "un-register" a version I gave to my brother so he could register it and get the updates. I also had a problem with a significant hardware upgrade to my computer that runs RF and I had to call KE and talk to them about it. They "un-registered" it and I re-registered with the new hardware.

So my thought is that the registration process collects some data from your PC about it's hardware when registering, much like our buddies at MS do when you register an OS.

Now it's been awhile since that happened the original issue was with G2, the one I gave my brother and I had the registration problem with the upgraded hardware on a computer with G3, so things might have changed.

That being said, I thought the license agreement was for one computer???????

The standard for that is that the owner is expected to NOT install it on more than one computer at a time. It is common practice in the computer industry even up to the largest mainframes.

And it is understood that if the owner of the software chooses to move it from one computer to another, that is perfectly acceptable. For example, if the computer you installed it on originally dies, or you simply choose to replace it, you can most certainly install your software on the replacement. You are expected to not continue to use it on the dead or replaced one however.

OK, if it works to send RealFlight support an email then their address as given by my G4 install is:

[email protected]

I just sent them one requesting the un-registration of the G3 I sold. I put "un-register G3" in the subject line. And of course, listed the Serial Number in the text.

I'll report back if they respond.

Thanks for the info.

I'm not going to be connected online for registering in the first place, so I'm not sure of the registration scheme for computers like these. I'll have to look at other sims if RF doesn't allow complete installation and operation for computers not connected to the Internet.

The registration process for pc's not connected to the internet is by mail. The registration form is included in the box with the software and hardware.

If your pc is not connected to the Internet, then you're not going to be updating online, are you. And to start an update process would require communications of some form that should more than adequately provide for an explanation of any special problems.

Thanks. No, the school computers will most likely not be connected to the Internet. Doing it by mail is fine with me. The biggest thing is that I would rather do the set up, etc at home than there before deciding on how to do each computer. It appears that my system will be faster with a better monitor, and without the hassles of interruptions.

If I were you, I'd get in touch with Great Planes, RealFlight, or Knife Edge about what you're doing. Schools that use software and applications like you're planning to do very often benefit greatly from the mfg's involved. The mfg's are usually very much interested in helping schools. It's great public relations. And excellent advertising. I'd suggest strongly doing any communications you plan to do by telephone. And do it before you purchase the products.

This mans idea is correct......you may get some very good benifits from Knifedge if they are aware of your educational connection. My brother gets so many benifits from Apple due to his P.H.D. and being a college instructor. I also run a Mac and all the software on it is via educational discounts.

Good idea and I'll contact KE since it will be for educational use. This is a start up course and we are all guessing at how to conduct it. I plan to write up the course for the school and possibly MA magazine. The students will build a LT-40 during one semester, and learn to fly them during the summer semester.

SoCalSal- I have the new iMac here at home and it would be interesting to see if G4 runs on it during the testing and setup. The only thing I think that could possibly be a problem is the video card. Aerofly runs perfectly.
