IMPBA’s new P-limited “spec” class rule proposal.

[Chilli]

Chuck, The only reason we have the spec controller in our district is because Dick Loeb and James Beasley already had a spec set up for the World Tunnel Championships and requested we do it in the district. Since I knew they were going to show up at all the District races and I needed their votes, I agreed to it. And in the end I'm glad we did it. Very few districts run combined classes and most nitro drivers have as much of a clue about ESC's as I do about running nitro a engine.

Danny, there is nothing wrong with extra caps but Doug won three Spec class D13 Championships last year without extra caps and he had no failures.

[Diegoboy]

Why can't we eliminate the ESC rule? If one so chooses to run the "spec ESC" they can. If one chooses to buy a cheaper T120, they have that option too.

Limited Battery and Motor should be enough.

[Doby]

So what are the approved controllers for the rule change?

They weren't pulling 90 to 100 amps either.
14 ga wire hanging out of those motors folks.

If I'm dumb enough to cause a component in my drive line to fail then I'd rather it was a $60 motor than a $100+ controller. (And...I am dumb enough to do that)

The only real way to run a spec class is to limit the amount of watts that the ESC will put out. I've spoken to a few who would know about this and it is feasible, i.e. the current limiters already built into the Castle controllers, and others. If Castle would make the current limiter an adjustable parameter then you could technically let a spec class use any motor & battery combo they wanted - just as long as the wattage available didn't exceed the spec.

Until we have this capability, and I do believe it's coming, then adding more rules restricting what equipment we can buy only causes more division among our miniscule ranks and is ill advised.

I've baked all the RTR motors except the AQ 1800 that comes in the Motley. Well....yet. I've torched both of the AQ speedos too. It's going to happen if you push.

My fastest LSH runs an AQ speedo. In 2009 I took second at the nats with a Castle and a ProBoat motor. The AQ setup is faster and runs cooler but it's a better boat too.

My 27" JAE spec rigger is pretty fast when I don't graze the pins. Crunchy. That one is all AQ.

My LSO runs an AQ1800 with a Castle120. I found the speedo in one of my boxes and the motor was on loan so I threw it in there. I ran the Castle purely because I had one. Works great.......but it never wins a heat.

One thing is for sure. If you buy the rtr speedo you wont be running that speedo in a higher performance class. To do that you have to buy more equipment.

Why does IMPBA insist on being a little different on so many things? I don't get it. We've been running the spec classes in NAMBA since the SV came out. Why not refer to that historical evidence? 3 or 4 years of history including multiple nationals. The history has shown us that the speedos don't really make the difference between winning and losing.

...The history has shown us that the speedos don't really make the difference between winning and losing.

I agree, So let me buy the cheaper T120's or Swordfish 120's

[Jeff]

Once again the desire to be diferant between the two organizations for what ever reason will reduce the number of participants in the class. There is a history for you. Just ask nitro guy's what class parity does for their clubs.
Once again this is like the government looking to fix something, there was not a problem to begin with. Surly Doug has too much freetime to come up with solutions to non-existant problems. Work on your boats, go racing is my sugestion.

I'm going to let this go sir as it isn't worth even THIS reply.

Have a great evening.

It is what it is fellas and all of these points have been made over and over. Let's just agree to disagree and drive on.
Run what you want to at a district level and when the proposal comes out vote on it!
Later
Doug

I think that we should all take a step back from this and wait and see. There is no rush to pass any new national rules because things are going fine the way they are now. We had a good attendance at the last FE NATS, the largest class being P-limited sport hydro (30+ entries). There is no need for new rules when the class is still in it's infancy.

[DPeterson]

Here's my rules proposal for both NAMBA and IMPBA:

Any club or district wanting to propose a new rules nationally must have a minumum of 3 racers travel outside their district to at least one race per year for a three year period. This is to assure that the proposal will have merit and would be for the benefit of racers on a national basis.

Along with this, new rules will only be considered once every three years unless it is safety related.

Just plain tired of select groups continually trying to effect rules on a national basis.

Doug

[Doug Smock]

LOL Doug.
FOR THE RECORD, AND I AM ONLY GOING TO SAY THIS ONCE.
I WAS ASKED TO PUT TOGETHER A RULES PROPOSAL FOR THE LIMITED CLASSES FOR NATIONAL RACES.
I HAVEN'T TAKEN ANYTHING UPON MYSELF NORE HAVE I WORKED ALONE. IF YOU GUYS WANT TO DO IT, GO FOR IT!! AS JEFF SAID I DO HAVE BETTER THINGS TO DO. I hope this is clear.

Please let me know if you fellas are going to write the proposal. I'll GLADLY step back and let you have at it!!

I look forward to hearing from you soon.
Thanks,
Doug

doug what was the reason u were asked to make up a rules proposal in the first place? what seemed to be the problem or problems with the speed controls or motors? also why did u propsose the esc's that u did ? they do seem to be the most expencive one out there for 60amp
