No I don't have the 3 page Rabbit GPS manual. Can you post a link to it maybe?
As for the Windows 7 issues with the registration of the mscomm32.osx I had issues even manually registering it. Turns out that its a simple fix. when you manually register it using the command prompt sometimes the command prompt doesn't run in Admin mode, and this stop the registration and causes and error. This is what was happening to me even though I run as admin all the time with my log in. I could install the drivers OK as admin but registering the mscomm.osx would not happen. I was getting an error and read up a lot of info on this error and fixing it, but nothing actually had the fix surprisingly. The fox was simple. Run the command prompt as admin. I did that and it worked. Not one solution I looked at told me that, but many solutions explained that the file must be registered as admin, but suggested other way to do it. In the end that's what I worked out and it worked. I just installed the software now on my win7 64bit notebook and had to do the exact same thing. I've been playing with PCs since I was about 17 ( I'm about to push 40 years now) so I'm pretty competent when it comes to things like command prompt work. I do a technical job as well, so I think I have decent mechanical aptitude. I used to be into Ham radio as well, so I am looking forward to getting to FPV down the track and starting to work on getting the best signal.
Thanks for the tip on expo. I actually took the expo out when making up the new TX config for this new rabbit board, but I think ill put it in. Might make it just that bit more controllable and less touchy.
I have seen a few videos on the GPS and it seems to work not to bad in the latest firmware, which i flashed into the Rabbit board first thing. I am hoping the Rabbit team keep on working with this board, and improving it. It is a great board for the price thats for sure. Just starting out with a Gaui330x and building several frames before going to Multiwii controller board, and now this, I think this is a great board for the price, and way better then the multiwii I still have. I have a second frame and the Multiwii is now on there. Just need some ESCs and I'll have a second quad to fly, though I think I'll get another Rabbit for it down the track.
