Back in the day when the Sliver was brand new(three years ago), there was a lot of talk about a 100mph 400 racer called the Skat. This worried us. So a kit and radar gun were procured to see if there was anything to the rumor. Kit built, the SkaT finished at 12.5oz-every attempt was made to see that the test was one of a best case scenario for both the SkaT and Sliver. After several cycles of the same pack, the power-trains were shifted from plane to plane. The Skat was three mph faster flat and level in a straight line, and EIGHTEEN slower out of the turns. For the record, I had the fastest straightline airplane at the NATs this year. I had three people come to me and tell me so.. I just don't fly nearly as well as Kevin so I didn't win.
Even when not bringing ultimate performance into the equation, it's damn near impossible to compare airplanes just on sight. The racers you see here and there have soo many variables that it's impossible to judge one from the other. One might have a tired motor, one might have a pack going bad, one might be overweight, and the pilot may not be a good flyer. A smaller racer will LOOK like it's faster when it's not. Even at races, if you have one guy who's fast(like anyone who has flown glow pylon before), it doesn't matter what you or anyone else has. The guy with experience will win every time.
Even though people have adapted to fly these types of airplanes over the last three years, the modelling public is still not ready for them. These are all small, finicky airframes. It's difficult to get the best out of them and to keep them in one piece. It's even more difficult to judge them by watching other people fly them.
Personally, if I knew that (Stinger being the exception) all of the 400 racers were within ,say, 5mph of each other regardless of the size, I'd get the biggest one I could. If for no other reason, you'd launch and land much more reliably. A broken plane doesn't get you the trophy..
Andy: I don't want to bash the SkaT because there's nothing wrong with it. It's just not a competitive "racer" outside of SoCal. It was designed by a glider guy. People thought they were fast at the time because that's all most people got to see. On a course, the Skat is easily beaten by a Sliver. Even I lapped a SkaT in my very first race.
There are maybe 90 Sliver kits out there, probably less than 35 completed. The Sliver has always been sold by word of mouth/email so there are few of them out there. By contrast, the Skat has a large fan base because it was a successful enough plane that you could catalog order it. You could actually GET a SkaT when you wanted one. A Sliver was a little harder to find because the original manufacturer was tied into too many other racing commitments. I took over last year and have shipped 39 kits since. They are still made to order, depending on your use. Scott(or is that Yamamoto-I have a first name too..) is right: It's not the value that a Sokol or Stinger is; I don't make a lot of money at this, and they don't fly or race as well.
If you are not racing, buy the airframe that's sexiest to your eyes and go be happy. 6 months later there will always be something faster, so just find a plane you like and enjoy it.
Ever seen a 400 racer thermal? Ever seen a racer that when balanced properly WON'T stall at minimum airspeed with the throttle off and the elevator pulled all the way back? Maybe you guys are looking at the wrong racers?
There, there's my plug.
