I flew it the first time in 2005 as the pilot of a Shoestring with a Fox 35 Stunt.
In April of 2006 I was building a Cosmic Wind with a Fox 35 Stunt. Then the Brodak Fly In flyer arrived in the mail and the LA 25, Brodak 25, Flite Streak, and Lightning Streak had been added to the list. The explanation was that Mr. Brodak didn't want his products excluded.
In addition, while a few people did OK with the Fox, a lot more preferred the OS. As explained to me by the recognized King of Fox Stunt, step one is to get a dozen of them and sort out the best two. With the OS Max LA or FP, it's two out of two.
I built two Lightning Streaks, one with the OS 25 and one with the Fox 35 Stunt. While the OS is clearly a higher quality product, 40% more swept volume is a lot of cubes. Testing proved to me that the OS 25 is the way to go, but a few guys still use the Fox and do OK. I like my Lightning Streaks, but good builders can match my speed with Goldberg products.
To me, the clear advantage of the Brodak Lightning Streak is the ability to build it with off-the-shelf wood, not machined LE & TE. But once, it's built, it's a wash. To me, the key element of a people's event is the ability knock out a couple units in a week and have as much chance to win as the next guy.
For a few minutes, I thought that I had been skated out of the event, but a double check of the posted long version of the rules jives the 2006 edit.
