Namba oval racing class changes ***

[dethow]

My point is....................we're not looking to run IROC here. We're not looking for equality. Only a power limitation. There's only so much power you can scrape from a 36x61 in runner.

Well said...
Words "spec" and/or "iroc" need to be left out of this conversation. "Limited" is what we're looking for and a size limit on the motor does limit the class.

I don't follow NASCAR much, but from what I know... isn't there a limit on square inches for their engines? Different types but can't exceed a certain size.
And I actually don't follow real boat racing either... but are there not classes that have limits to engine sizes? I bet they don't say you can only run a small block Chevy.

Just sayin...

The goal of changing the "limit" would be:

Retain existing racers
Making it easier for a new racer to join in
limit power

As for actually attracting brand new racers...............nothing has worked better than limited since I've been racing. Buying something that is race-able right out of the box was the key IMO. That said, this is less complex than what we had. Even easier to find a boat that fits right in out of the box. Will that bring new guys? Is it right? I have no idea. What we have now though can't be sustained.

I vote Terry Davis for NAMBA FE Director... The heck with Brian...

Bwahahahahahahahahaa....

Weeny. You're off my Christmas list.

Just thought of a side effect.

Although not necessarily a "goal" for a limit revision, the change would make it easier for brand new players in the boat market to comply with the rules. Companies like Promarine, Venom or even Atomik could simply bust out their calipers and figure out if their boats are legal. None of this "get it tested and approved by this guy, that group, those dip.....its from MI". None of that rot.

So in theory, more out of the box legal boats. Competitive boats? Who knows.

Last weekend we had our SCSTA/Nitro/FE race. Classes qualified : P-Ltd Sport Hydro, P-Ltd Cat, P-Ltd OPC, 1/10 Scale , 1/8 Scale.

100_0161.jpg

It was the usual SoCal warm & fuzzy lovefest.

Oddly enough there was NO discussion heard resounding in the pits regarding changing any motor requirements. Seen were : AQ 2030's, AQ 1800's, PB 1500's & [ call the Tech Police ] PB 2000 KV. FWIW last race a bone stock newly purchased PB BJ 29 showed up with the daringly defiant 6-pole 2000KV motor for a new entrant (one who BTW took High Points in last year's year-long three-state P-Mono series so she was an experienced racer. (No arrest was made) .The boat was so slow it needed a calendar to judge its speed. Then, for whatever reason and in a daring departure from reality/legality I also tried the PB 2000KV in my P-Ltd Cat. To avoid arrest and incarceration I dressed as a large Honey Bear. It was a slug & I changed it out for a AQ1800. Took 2nd overall. (Love those Starbucks gift cards/Jitters.)

If there's a point to be made I'll say this : Given that this year SoCal FE is FIVE members down (geographics & the big C), and two locals are recovering from surgery or pre-marriage extravaganzas, the current crop of gas/nitro racers are crossing over and saving the FE class ranks. AND THEY JUST WANT TO BUY A BOX STOCK RIG and not mess with changing motors for the powerplant- de jour. What's winning are bone stockers with nice props AND premium batteries (and years of making good starts and knowing how to stay in lane one.)

To rebuild racer ranks my take is that unmolested store-bought rigs are the only entryway path to re-populate the classes. Given that (with the exception of the NAMBA 2-Lap and SAW events) there's no big emphasis here in the land of fruits & nuts on which motor is/is not "Legal" . Winning is secondary to just hanging out with what can be described as a big family get-together. OK, I'll concede that this is likely not be typical of club racing elsewhere. We've possibly O.D 'd on too much surf music & pink tofu. Whatever.

Number one rule of racing.......have fun. Pisses some people off when I say that but if I stop having fun I'm out.

Tony, this change would basically be what you guys are doing. We allow the 2000kv Blackjack motor too btw. Nobody cares. Maybe they would if they were stomping the crap out of everyone though.

Making it as easy as possible while still limiting the nut jobs (me again ) might bolster our ranks.

Darin,
Do you know what the constant amp rating on the Proboat/Dynamite 2000kv motor?

This isn't listing in any info I can find on this motor:

http://www.proboatmodels.com/Products/Default.aspx?ProdID=DYNM3910

But it is a factor into being an allowable motor per NAMBA CD discretion rule. Must not exceed 5% difference from other allowable motors. Aquacrafts are rated at 50 amp constant.

Jeff B is the only one I'm aware of using this motor in his boats that are not Blackjacks or Geicos.
He started using a couple of these race # 2 this season.
Weird thing is that Jeff has been winning more lately... just sayin'

Maybe he's getting better

[Darin Jordan]

Tony makes my point perfectly above... LOCAL CLUBs can do WHATEVER the heck they want to attract racers in their arena. They already are.

But, you can NOT have a class, Nationally, or "records eligible", that operates under these loose rules. THAT part is really what this discussion revolves around.

A local, "Run-What-You-Brung", or stock RTR, or whatever class, is EXACTLY what the clubs should be doing.

Darin,

I really don't know. These numbers are all just made-up anyhow. The only way to know for sure is to push one until it blows.

From my bench testing, the 2000KV Dynamite motor is down on power, and gets hotter, at 100A, compared to the others. Wouldn't be my first choice in an application that needs some torque.

[T.S.Davis]

Moose has the stock motor in his Blackjack I believe.

In my MC with an AQ1800/Oct M445 the motor is usually @ 135 deg. F as soon as I yank tape. Sunday the PB2000 came in (same boat/prop/last place finish) at 165 deg. F. Golly

Yeah... but that's an 1800kv motor up against a 2000kv motor with the same prop. Using an AQ2030 compared to the PB2000 would be a better comparison. Would it not?

Understood... that's what I figured.
Which is why I question why this (constant amp ratings) is a factor mentioned in the NAMBA rules under CD discretion for usable motors.

And in which case...(the PB2000) if allowed in an event, it could easily be viewed as illegal because it's not in the list and there is no documentation of its constant amp rating as required by the CD discretion rule.

So its official... V3 Blackjack and Geico are NOT legal and the only legal out of box boats are Aquacrafts. Something is wrong there and it needs to be changed sooner than later.

[Darin Jordan]

Here... this will clearly show what Tony is referring too. Both motors, loaded to ~100A@4S for 60-seconds. Look at the Loaded KV, the KV-Loss under load, and especially the Delta Temperature (temp gain after 60-seconds). Clearly, the DYNM2000 is inferior, regardless of prop.

NOTE: By loading them all to 100A on the same 4S Lipo, it means they are all being tested at the same power output. Much more accurate than "which prop did I use"...
