Upgraded from Traxxas Blast to SuperVee 27 and wow!

[Tony Vega]

On a whim I bought a Traxxas Blast for my son and I and took it to the lake. It became apparent to me that it just wasn't what I wanted but it was still fun so I started my research and narrowed my selection down to the SuperVee 27. All I can say is what a difference. The boat is much faster and being a R/C car guy, I was impressed. I am hooked on the boats now and look forward to adding an additional turn-fin and adjustable trim tabs.

Welcome to the board, Tony. The trim tabs help. Are you running Nimh's or lipos? Nice looking boat.

[Tony Vega]

For now 6-cell Nimh because I have lots at my disposal from my days as a Trinity/Losi driver. We use lipos on the car side so I guess it will only be a matter of time before I make the switch but I'll want to install a Lipo cutoff device first as Lipo fires can be pretty nasty.

Why do people coat the wood mounts? Wood rot? What's recommended? For the bolts in the rear I used Shoe Goo instead of silicone to prevent the leaks. I also used it to seal the rubber boot on the steering linkage as the factory job was sub-par.

I have in my shopping list so far... X642 prop, turn-fin, Grim grease, and adjustable trim tabs. Any trim tabs available in the matching blue from OSE? Any other recomendations? I'm eyeballing the ose-svcable flex cable but I don't really understand what it does.

It is supposed to be stronger and the stub shaft is better aligned.

Welcome to FE! The four best mods for a stock SV are:

- GrimRacer/ABC 42x55 prop
- SV27 specific adjustable trim tabs from OSE
- Port side turn fin
- 6 oz of lead taped in under the motor.

These are for a LiPo setup which weighs less. The added weight helps keep the boat on the water at higher speeds or rougher water, you may not need it with the NiMH cells.

Coating the wood inside keeps it from softening when wet. There are a few issues with the SV27 that the owner needs to fix, those are covered in the SV27 section and you seem to have found them. But the SV27 was, and remains IMO, the best overall entry level FE boat ever. I like the look of yours a lot.

Thanks for all the recommendations.

Anyone use Loctite 2-part epoxy instead of the Z-poxy?

What kind of speeds do you get with this setup?

My mods are the 42x55 prop from Grim, Lipos(2s 5000mahx2) 5 ozs lead under the motor and a port side fin fabricated from stainless by your truly. I made the fin just a little longer. I don't think the stock fins are quite long enough. May cut down on the speed, but the stability in choppy water in a turn is worth it. I don't have any "official" speeds yet, but I would say 40ish. This is me comparing timing between two points. My monster truck will do 45 on radar, and this boat is right in the ballpark on the clock. The only other mod will be to upgrade the motor cooling from stock. It just doesn't cover enough surface area.

What motor cooling do people most recommend for the stock motor? I have seen some nice looking billet aluminum jacket ones.

I going to order the one that OSE has listed for the SV motor. Here is the link to it.

I wonder how that one compares to this one...

[scooterP]

Those look nice!! What kind of costs for one? One thing is they appear to have more surface area which should be a good thing for cooling.

[Tony Vega]

$25. I like the look of them but the one from OSE is much cheaper in price.

even 40.0mph looks fast in a SV
my ERevo does 60mph on 4s, and my SV is just as much fun at 40mph

Well, I have just discovered one thing that helps cooling tremendously at lunch today. I had already put on larger tygon tubing, did the rudder mod with another water pickup at the bottom of the rudder. The motor was still running way too hot after a couple of full throttle laps.
I went in and put a "T" fitting before the line goes to esc and then another "T" fitting where the line comes out of motor and esc then to one line and out. The motor went from too hot to touch too nice and warm. I still can't believe it.
