sv27 GPS Speeds!!

[TerryC]

FWIW, I think at the Valdosta SAWS this past weekend Chris Harris did a verified 49.9 mph for a two way average record time with a SV. This was in the "modified" class.

Actually the 49.9 mph was in the open class, Modified was 44.3, and stock was 39.
some very good numbers I think for all the classes

These are verified on the lights and are likely the best numbers out there. They are also two-way averages, which likely represent the best "true" speeds for a boat.

So it gives you pause when you see claims of 50 mph SVs!!!

I know for a fact that my SAWS speeds are lower than what my GPS says. Keeping a boat on the water for 2 consecutive passes really tells you what the boat is doing as opposed o the single virtually instantaneous max speed that a GPS records.

Oh, and I fixed the error in my previous post. Thanks for getting me straight on that.

that is very true in testing before i went to the saws this weekend I ran 45.5 with my sv in modified trim with the gps and at the event that same setup only got me a 41.9 average. so the setup I used to set the 44.9 in the modified class was completly different. Im still surprised that the hull can handle 49+mph.

Mind sharing your set up? Motor/ESC/battery/prop???

My SV with stock gear on 4S1P / 25C 3300 / x440-3 runs GPS at 39.2 best speed. I figure it would be 35 - 36 on a true SAWS run.

Sure I was running stock aquacraft motor and esc, 2-2s 7.4v 5000mah flightpower packs, and a prather 230

[Bill-SOCAL]

How did they define stock/modified/open??

Chris Harris did not run a SV at FE-IV... Reed Eagle ran an Open class SV at 49 mph

Sorry if I got the names wrong. I corrected the errant post. Regardless, that was a screaming speed for an SV!!!

it's also interesting that Reed's SV27 was a [2s-2p] set-up... not a 4s package

i'll let Reed give the details of the set-up

What modifications did "Open" allow?? Anything goes as long as it was an SV hull?

must have origional hull bottom and top... anything goes, be creative

Here are the rules for this past weekend and possible other races.


2. BOX STOCK. Just like the boat comes out of the box. For power ...any NiHm cells ONLY and you may upgrade your prop to metal as long as its a Grim Racer prop, only. Any adjustments are acceptable so long as they meet this general guideline.

3. Mod Class. must have Original boat hull and lid, SV motor, SV Strut and Rudder, any power - Lipo allowed. Plus any prop, any esc or radio. No restrictions on turn fin or tabs.

4. Open. Must have original Hull bottom and original lid. All else is legal. Be as creative as you can. Go Fast

[Bill-SOCAL]

Be as creative as you can. Go Fast

That about covers it!! You guys did just that!!

...wish I could've been there. Makes me feel pretty good that I'm doing the speeds I'm doing though...whether people believe it or not.

Just the difference between GPS "max" speeds and the average of two passes on a 330 foot course.
