N2 Classes

[BILL OXIDEAN]

A2EE_1_20130627145878818.jpgThis is an Excellent choice for a limited N-2 sport hydro. I run it on a 550 motor that spins 5000kv

You can find 'em for around 300bux RTR. All that needs changing is the motor mount. 24 inches, handles like a dream.

Here's a video. My personal boat was used in part of it while it was still stock. Mine is the one in the aerial views..

Thanks Bill. I think the DF Vortex 22" is very similar to this hull. I'd prefer the 24" or larger.

Tenshock SC401 V2 motors look much nicer than the Roar motors you run but, you make yours work well.

It's just that you have to silicone the 36mm cooler onto the can as most don't seal with those pesky ridges.

Tenshock do a bunch of boat motors that don't have ridges and will take jackets easily.

You may be right Ray! Let me get out my ruler. I could have sworn it was 24..
Those tenshock motors look great!

Not responding to the question answers my question.

Doug, were you waiting for ME to respond?? My answer is I'm not sure. The only boat I know of that "set a record" and had to be recovered to be tech'd was Joerg's, and I wasn't there. I haven't personally experienced the need to recover a boat that has or hasn't set a record, so I really hadn't a need to consider this. Sorry.

As for your assertion that people are going around "tooting about it"... If you think that's the case anytime someone posts the results from an event like this, whether it's their record or someone else's, then that's really kind of sad. Exciting news about the hobby is fun and exciting to share, and it's important to do so. If it goes beyond that, then I can see your point, but I don't think that's the case too often.

Now, back on topic... There was a question above concerning building an N2 Sport Boat... I am about to pull the trigger on and ML Boat Works G265 with the new GP cowl. We'll see if I can get it built and developed in time!

Oh, and I actually couldn't respond sooner... was out of town with my 14 year old son on a deer hunting trip, and just got back last night...

You need to invite us out your way next time... it was a tough trip this time out and we really didn't see too many deer, and definitely not any "shooters"... I hear you have a little better odds back there!

In Wisconsin we can get them with our car. Just drive around backroads at about 5:30 pm.

I have a lot of car guys around here and the question often comes up about using there car motors and batteries. I think an n2 roar spec is an excellent idea for club use.

I've brought the idea up here with PSFEMBC. There is a lot of mis-understanding about how the ROAR motor designations work. I think sticking to the ROAR allowances/approvals would provide a good regulation of legality, and one can be assured that the motors of a particular wind would all be basically the same power/quality. The rules are very detailed about what is/isn't allowed.

If you allowed "any ROAR approved 05 sized motor on the ROAR Brushless Approval list, with the exception of those designated for 1:8 or 4x4 SC, and a wind of 10.5T or greater", then you'd have a class that would nicely power a 22-25" Sport Hydro comfortably into the upper 30's/low-40's, and a smaller mono up in there as well. For example, my N1 Mono can easily make 37-38mph, and has recorded a SAW pass of 45mph. That's a 17.5T. The 10.5T would be more around 4500KV and would be ideal for 2S1P.

For smaller ponds, or just for a new challenge, this would be fun. 1/16th Scale Unlimiteds would be legit as well.

Did you water cool your N1 boat Darin? That wood boat with all those hand made goodies on them? I have a nice 4800kv motor in that Roar class, might try it out in the spring. HK doesn't sell the motor I have anymore, nice thick windings too, sensored.

That "wood" boat is actually all carbon fiber, except for the 1/64" ply with carbon fiber laminate for the deck.

The first ROAR 17.5T Stock motors (Losi, Hacker, etc.) could be water cooled pretty easily with a standard water jacket for a 36mm motor. However, the newer modular designs are tougher to do because of the 3-piece cases and cooling vents. I just use an aluminum cooling coil now. So, YES, I do.

There is so little amp draw with a true N1 setup that water cooling the ESC really isn't necessary. About a 36-amp continuous is all you are going to get... MAYBE 40...

With the 10.5T motors, it will pull a little more.

[ray schrauwen]

Do you think a 1415 Neu sized motor will be competitive in N2 Sport Hydro compared to a 40mm 1515? I've noticed that 36mm Diameter leopard motors are more efficient than their 40mm Dia. motors. Wondering if this happens with Neu motors also??

Darin, what do you mean by true N1 setup?

[Darin Jordan]

Darin, what do you mean by true N1 setup?

Some here are running other than 17.5T ROAR approved motors in their clubs, and calling it "N1". I'm talking about a NAMBA legal N1 Mono setup. ROAR approved 17.5T motor, or a 27T Brushed motor. Anything outside of that is NOT a "True N1" setup...
