The ultimate FPV glider
Today I started the build on my FPV Supra. For those of you that don't know the plane, check out the website of Kennedy Composites or watch the movie I made of the non-FPV version
For me this is the ultimate FPV glider, even the ultimate FPV aircraft. It's hollow-molded full glass with carbon fiber reinforcements. The Supra travels at around 40mph, but it can be slowed down to ~10mph for landingings. The top speed should be near 130mph. The glide ratio is out of this world (~1:40), the plane can fly forever and then some on a very small LiPo pack. With the power system I have on board, it will climb at 17 meters per second (~3300 feet per minute). It will be built from the ground up for FPV.
This build includes a couple of "advanced" stuff such as frequency diversity (2.4GHz & 1.3GHz), how to use FPV gear with a 5S battery and how to install FPV gear properly for long range (noise-free) and low drag. I'll also re-build my ground-station and post pics here. There will also be some non-FPV stuff going on ranging from R/C TX programming to build tips for composite models.
I hope we can get a good discussion going because at the end of this build-log I will release a PDF with the contents of this thread in a more structured manner.
Anyways, I got started today ... nothing FPV related yet, just some normal build steps ... here's the pictures:

BlueSky: Yes, it will be 1 camera and 2 VTx. The 2 VTx will take care of the problem arising with the carbon parts and to guarantee a good video connection even when banking the plane heavily (polarization diversity). I'm back to square one on the camera mount. Initially I planned to mount the pan servo in the fuse and have only the servo-head stick out, but that's not going to work (not enough room). My best choice so far is to glue everything on top the wing.
jsullivan/guyavitov: the 4hour mark will depend on whether I can squeeze enough battery in there. the second vtx will probably need to be turned off for a 4h flight, as I'll be flying with a 5S 2200mAh (that's all that fits).
aviatordave: No, there's no duct tape on the ESC. The whole ESC is shipped in a lightweight aluminum case (I think it's aluminum) for cooling and noise filtering. This really is the best ESC I've ever seen ... there's so much thought put into this (switching BEC with redundant outputs, for example!) ... but it comes at a price
The tape you see wrapped around right now is just to keep the wires out of my way while I work on the fuse.
