I think Tims was turning the rudders in weird positions to stop, not an air break...
don't quote me though.




As my memory recalls, Joerg was playing with the breaks but was never successful, You (Jan) and I can do a bit of research to find out the deal here
don't quote me though.

As far as I know Harris is the only one that has had success with the air breaks.

So now I see only 1 out of a possible 3 have sucessfully run air brakes/spoilers, which to my observation increase the load / drag on the front and slow the boat considerably for a turn or can be used to scrub off speed before the lake edge becomes a sponson attachment.

While my 4S rigger is layed up awaiting a new esc I will look at this idea.

I have another mad idea that needs research and then build time time first.

Yup [ I'll quote Ya' Bro] I do beleive you're correct ; rudders toe'd in or out.

How about deploying a chute ? Works for NHRA !
[ the rocketry crowd has all kinds of chutes]

[BILL OXIDEAN]

Now that would probably work, but it would probably have to deploy from a small perch on the back or a raised transom.

[Doug Smock]

The backup pass would be tough though.lol

Uhh.. yeah pretty tough lol! Backup passs won't look so hot.

I love time trials! Have been many times with Ed Hughey. A great time.

One day i mistakingly came up with a fantastic way to stop the boat on a long high speed run. It is fool proof and works every time and you dont really have to practice very much. As an added plus it can be used at any pond. I named it "Lose Contact And Ram Straight Into the Inbankment Stopping System" Trust me ...it has never failed anyone that has unwillingly used it and i have tried it twice in my boat adventures. LOL.... Dear god talk about a bad day!!! And by the way ,there are never any back up passes. AT ALL!!! LOL

[Doug Smock]

I remember having difficulty recovering one of Paul P's hydros a couple of years ago in Valdosta. We all saw where it went aground and I had passed that area twice with the retrieve boat. I finally realized that I wasn't looking high enough and found it perched 4' up in a small tree. LOL
The boat was a kevlar Darkhorse shovel, not a scratch on it!!!!!!! Brian builds a tough boat, If I remember correctly it was traveling better than 80mph when it left the surface.

Yeah, but think of the fish & turtles you'd snag ! Yummm...

[Simon.O.]

Yeah, but think of the fish & turtles you'd snag ! Yummm...

So we all agree that a good saw run is TWO passes back to back.
Pop the chute at the end of the first run and then ditch it. A third channel can make this happen easily.

Don't worry about the chute for the end of the second pass, just use Gary's terrain assisted velocity reduction system.

I am pretty sure Gary will not mind if others copy his idea.

I have dabbled with it a bit and it is more effective with a steeply angled rock wall. This really scrubs off speed. The sloping grass embankemnt is more gentle but takes more time to slow the boat.

[Rex R]

obvious answer pack 2 chutes deployed sequentially. a 10" chute can be packed into a very small package .

"Terrain assisted velocity reduction system" Sweet !!! Can i market that? LOL

[bwells]

How wide are the gates and do you have to make steering changes between them? Do you stand perpendicular to the run or are you in-line like on a platform?

[properchopper]

the SAW course at Legg Lake has a driver's scaffold midway between the lights.
You have at least 100 feet of corridor to make the run. The straighter you go the faster the time will be; a diagonal path is longer so you want to stay centered as much as possible. There's plenty of space at either end to accelerate and decelerate, unless you're running over 140 or so.
I've recently tested a new technique to stop; the Speed Pond Lateral Acceleration Terminator [ SPLAT ] and it works as described

When going with times you really have to make sure you have a straight line shot or your speeds will be off...THis is where a GPS does not care about the shortest route.

So it really comes down to time and not speed...speed is figured after the fact of the time.

My idea... put a string line down the center above the course and run from behind so you know you ran the course straight.

From the bank it is very misleading if you are truly going the shortest route and straight.

Hey... but who is counting milliseconds...besides the lights :)
