Default Record SAW vs Record Oval vs Heat set-ups

What are the differences in nitro hydroplane set-ups for record SAW versus regular Heat racing set-ups.

Do they even use a turn fin? Ultra small rudder? Over-stressed engine? Ultra light-weight? Small tanks?

Are the engines built like 'dragster engines' creating huge horsepower on higher nitro and heat levels with only say 10 runs available from an over-stressed engine?

Where could I find out about this type of R/C racing besides just trial and error?

Some will use a turn fin but a much smaller one. Engines are pushed to the max in the quest for an extra 1/10 MPH. Hull life can be short as they will fly off the water with the boat trying to re-kit itself. Front sponsons are a lot different as they have about enough to lift the front out of the water and don't offer much buoyancy if the boat stalls. Some records have been set with off-the-shelf production 'riggers though. The current speed record holder in nitro was with a production boat that wasn't completely dialed in and not ideal conditions for a record run!

there is REcord setting goin on in Huntsville, Alabama yerterday and today..

for saw set-up, make the boat as light as possible that still can handle the boat max speed, shave those parts that creates lot of drag by trimming the turn fin the rudder, struts as much as possible it's streamlined but the boat can still make turns.

oval haet set-up probably just like regular heat race set-up.
