I really enjoyed your video,btw! Watched several times with my morning coffee! Appreciate your response, Dustflyer. Was the Reaper in this video the Simjet or K100?

Glad you liked the video! I have a few more at my channel:
http://www.youtube.com/user/Jetsplus You might get a kick out of the P-80 "Afterburner" video. I also have a few other Jet Rally videos and a video of my Hotspot. You may get a kick out of my "Sharpest Knives" video too.
The Super Reaper in the video had the Simjet 1200. As you saw, I came a little too hot! I should have slowed it down even further. If you search YouTube for Super Reaper videos you will see that most guys make the same mistake I did, they come in way too fast. I found one video; however, where the guy brought it in at what seemed like a walking pace! The landing roll was about ten feet!
If you do the speedbrake mod, you only need one servo for each speedbrake. Just run a threaded horn through a hole in the lower half of the speedbrake. Hook up pushrods to opposite sides of the servo horn. When the servo turns it pushs one half of the speedbrake up and pulls the other one down! I wish I was the clever rascal who engineered it, but it was my dear friend, master modeler and flyer Joe Weizer.
I like the Super Reaper too. I believe the kits are only about 400 bucks, you can probably build one in a day. I am frankly surprised I don't see more of them. Mine is the Mark I, the latest one is the Mark II which looks a lot better. Once it's up in the air the Super Reaper is definitely one of the cooler looking model jets around.
Here's the speedbrake setup:
