Do a search using " UL-1 air dam" on OSE and RRR and your going to get some good info. Here's the basics for the UL1.
Seems you can use pool noodle cut to shape like the "L" shaped plastics we see being used. You dont have to buy anything from anyone to get the right materials. Go down to your local home depot/ eagle hardware/ whatever and get a 7" long, 1/2" by 1/2" plastic/lexan "L" shaped corner/ edge protector or if they have aluminum angle stock buy a 1 foot piece. Use some double surface foam tape or even just use hatch tape and put it in place. It needs to be approx 2 1/2" behind the leading edge of the sponson bridge or center section depending on how you define that part of the hull.
I have tested and found that a 3/8" x 3/8" works as well if not better then the 1/2" stock. But it seems more folks have added comment using the 1/2" material and I am not going to debate the size. Use what you like. It turbulates the trapped air and keeps the hull from lifting. Just like the wing of an aircraft. Something this simple can add more then 10mph on your top end.
Wade do you notice any difference is it working no more wobble ?
I still get a little wobble but I still have yet to run it without some/little chop. I do notice that it keeps the nose down a little but I also experimented with battery placment/etc to help with this and to also get it to plane without always "gunning" it.
