Does anyone know where I could purchase a dedicated s8e kit or plans? or do most people scratch build or convert a discus launched glider? I have rc experience and have launched an estes stratoblaster and the old hobby labs sr71

There aren't many RC/RG kit manufacturers out there, let alone any who create kits for FAI competition. Venus Model Rocketry (http://www.venusrocketry.com/index.html) has some unique competition-oriented kits, but I don't know if his Gizzard RG (http://www.venusrocketry.com/RKT_004.html) could be converted for RC control, and whether it would meet FAI requirements. Qualified Competition Rockets (QCR) also makes competition-oriented rocket glider kits (http://www.cybertravelog.com/qcr/gliders.html) that perhaps could be converted to RC.

R&R Model Aircraft (http://www.randrmodelaircraft.com/) is the only vendor that I know of who specializes in radio-controlled rocket gliders. They may have something that could be used as well.

The Edmonds Arcie-II, available from BMS (http://www.balsamachining.com/CATALOG.htm), is another RCRG kit that is available. Again, I don't know how it would fit into FAI rules.

I would hazard a guess, though, that pretty much all competitors in FAI S8E scratch-build their own gliders.

It should be obvious from reading my previous post above that I have no experience with RCRGs or even with RC aircraft in general. Otherwise I would have mentioned another potential source: converting RC glider kits to rocket power. My guess is that you already know of more vendors of such kits than I do, so I'll stop right here. Good luck!

Scott from www.themonstr.com is working with TopSky to create a kit based off their DLG kits. It's in development right now. See the end of this thread: http://www.rcgroups.com/forums/showthread.php?t=403984

George Gassaway has some plans on his pages:

The last kit that was close to an S8 was the Cuda which still pop up on ebay from time to time.

Converting is a great place to start. My 1st S8 legal RCRG was a converted CRRCC Terminator HLG. http://charlesriverrc.org/articles/terminatorhlg/terminatorhlg.htm
Then I got a set of wings and scratch built my second one. I'm on my 3rd S8 model now.

Converting one of the modern DLG planes is pretty simple. Usually it involves adding a motor pod (US pilots like them above the wing, Europeans tend to favor the bottom) and maybe adjusting the tail feathers a bit to keep them out of the exhaust. In the RCGroups forum linked by seanmca79 is a set of instructions based on the Blue Arrow Venus but they can be used for almost any conversion.

The Top Sky kit in the works is pretty interesting.

I concur. Until someone comes out with a new kit, it is a very good option. Another example of a conversion can be found here: Zuni build thread (http://www.rcgroups.com/forums/showthread.php?t=945621).

It may not be the best S8 competion model out there, but I wanted an S8 trainer that can be flown as an electric motor glider also. Early mock-up photos attached.
