Gotta be the Aquacraft SV27. Capable of 40+ mph w/ very little mods and priced at $279.00. Batteries not included!

Tend to differ

The SV27 is the best by a mile of a bad bunch. Nonetheless it is very limited and ties you into a setup which is not competitive unless its a spec class for SV27's

Try secondhand on RRR forums or something liek an RTR CLassic Hydros shovel with a NEo-X motor and 4S lipo 40 mph ....

Are you new into boats? If so, an excellent choice would be a SV27. Easy to setup and maintain, and very cost efficient. Depending on setup and prop choice it can give you 30mph-43mph with all stock setup (12 cells). Excellent price. It got me into a new aspect of the hobby....easy to learn, but challenging. Lipos will yield +45mph. Throw in an 8XL motor and lipos and you'll be +50mph. It also comes with a warranty. Not that many problems with this boat, even though it's RTR.
If you buy second hand and you're new to boats, you don't know what you're getting. You also don't know damage that's been covered up. Also, I don't think there's a return policy on second hand. Just something to consider.

SV27 is the way to go if your running local or in common sense clubs.

http://www.offshoreelectrics.com/MainPage.htm did have some in stock.

If your into professional racing with groups like NAMBA or the IMPBA, you will need to spend $1,000 + to compete.

tGrant, If you go SV27,
If new to rc period, I would recommend doing some homework on lipos first. That way you can make an informed decision about whether you want to use NiMh or lipos. I'm talking from the safety aspect. If you decide lipos, make sure you get a fire safe storage container (ammo can) and a lipo sack (fire proof sack), and don't store in you home.
The packs I've heard of people using are +4000mAh rating, Already built....just plug them in. I'm not sure about the 2S or 3S config. You'll have to look around about that. Hint hint: I recommend looking in more than one place for these answers. Keep in mind, for competition purposes, this hobby is going into the lipo realm this year.
Either way, get a charger that can charge Nixx, lipos and possibly l-ion. A dual charger with at least 10A output (and can charge at least 2 packs at a time and has a dc converter with it for field charging)........look at the MRC977 Superbrain (this has a tendency to false peak.......it cuts off the charge early and you have to monitor the cycle.......which is good anyway).

I've done alot of testing with props on the SV27 with 12cell NiMh and have found the carbon fiber (CF) K series Graupner 48mm (0 cav, unless you modify it you have to slow down for cornering) to be very aggressive, to say the least. This will literally launch you out of the water (croc roll) and yield 35-high36 mph on light chop and a good setup (140F batt temps and 125F motor). You will have to monitor batt temps (don't go over 145F) and make sure you have a good setup. For the metal props......I recommend M445 (.5' cav and +37mph, excellent control wide open (WOT) throttle and cornering). (129F batt temps and 110F motor). The x642 is pretty fast also with mid 36mph (0 cav and great control WOT and cornering). The X440/3 (1-2' cav) will give you +40mph (Jallen got +42mph) with great cornering and WOT also. If you have alot of turns in your racing or sporting around, like an M-course, maybe go CF45 (34mph but good handling) and CF48, or metal props (much beter) with the M445 or X642. All out oval, go as fat as possible, try the X440/3.

To ensure propper setup (prop, your trim tabs, and strut position) you have to monitor temps of batteries, motor, and ESC. ie. If you run a CF48 in a stock SV27 and don't have the setup correct (like running the boat too wet, or on dead calm water with wrong setup), you can easily fry a pack or two in half a run. Make sure you always get batt temps with an IR temp gun when trying new props or trim tab/strut settings.

If you're NOT new to boats ignore this.
Hey, I was new to boats back in Sep 06. All of this isn't meant to scare you, but you can't just go fast in rc boats by throwing a prop and batts in. This is meant to give you an idea about what's required for setting up your boat, and will enable you to enjoy it much longer. You have to make sure the boat is setup for the water conditions and that the prop won't draw too much from the batts at one time.

Oopps. The CF props ($5-$6) can be bought as is (in the bag) with no sharpening or balancing required. The metal props ($12-$16) have to be SBP (sharpened, balanced, polished). Most sites tell you how to SBP, or you can pay an $15-30 for the service.

CF props
MHZusa.com, or Offshore electrics,
Metal Props
(Fine Design, Offshore electrics)

Retoabcr,
I was just giving the guy some info on the SV27. No other info was offered on other boats (except Jallen, myself, and SJS, by different owners of different boats. Noticed I said, "If you go SV27.....".

I also let the guy make a deccision about lipos and asked some questions as to the experience of the person who started this thread. I'm not forcing an opinion or disagreeing with anyone. I do however, know, that the SV27 will smack various other hulls in comp, whether they're nitro or electric, hydro, cat, or deep vee.

Should the fact that someone owns a particular store change my opinion, or even the test data that I have run and verified myself? True, they may have more experience, but that's not what is being asked. But thanks anyway for the info on another FE site.

The guy simply wants to know what can be purchased for $300 for a really good deal. Do you have some info to offer the poster of the thread?

Reto,
What is your problem? You already wasted 45 characters. I was going to PM you and ask, but a retort out in the open seems more along your lines.

If you can't get into a discussion w/out childish overtones and can't offer anything constructively to the thread, or forum, don't type at all.
