Where are the ROAR New Approvals?

But Li=Po 7.4v only peaks '8.4 while the so called 7.2 v c/cells peak @9.2v then settle down to around 8.6v ,while the li=po settles down to around 7.9
so the li=po is more relistic in it`s quoted voltage unlike the ib`s which seem to get more & more powerfull instead they could be 1.3v cells but with wrong shrink on it just to stay legal (7.8v pack instead !!!!!!!!!!!!!!!!!!!!!!!!!!! c-cell
proberly why c/cell batts are making things go faster , the r/c batts are made just for racing ,so they mess around with the internals to make them more powerfull (but keep it secret!!!

Look, at the end of the day, (as I have said before, solve the problem), and you do that by placing a voltage regulator inline. Stock gets 5.0 (or something) volts to the motor, 19T gets 6.0 and mod, is open. Simple device, simple tech and then source of power is not longer an issue. I'm not the one make this device, but if they have it for recievers, someone can make one about the size of 2 Deans plugs and call it a day. But this whole BS argueement about how LiPos are advantage or less safe then the current power source (NiMh) is just that BS.
Is sure does seem like we butt heads on line... sorry for that... you are educating me and I'm expressing my views... nothing more then that. I hope others do not mis read our postings....

Roar is going to do what they want to do....There's nothing any of the racers can really do about it but elect another president and hope he does a better job than the past few President's have.....Which I believe there is only one person running with the balls to do it!!

Simply put, I do not see how anyone thinks that LiPos cost more in the long run then NiMh. .

The one issue I have with all this and it was brought up before but everyone is afraid to address it is this:
There many factors that are very dangerous in our hobby that have nothing to do with batteries, ie. toxic chemicals, super hot surfaces with out any heat shielding, exposed high speed gears, exposed fans, cars flying through the air near turn marshall heads that are not wearing head protection etc. why are all these matters ignored? When I bring friends around and explain the hobby they almost always laugh not at grown men playing with toys but at the balancing act we play with safety.
I am not saying don't ban this or that what I am saying is it is time to be consistant in the decisions being made because as they stand now if I were in a posotion to have my vote mean something my vote would be no confidence.
Before anyone tries to claim I am biased remember I work for the largest R/C Ni-MH battery matcher (unless you work for GP, IB or the like you are not technically a manufacturer) we produce Li-Po's and we make brushed as well as brushless and we also make Nitro engines. Whatever happens we have our basis covered my main concern is for the future of our hobby as a whole.
This is the 5th industry I have worked in over my career and it is by far the smallest and based on everyone blaming everyone else for specific issues rather then working together to make the whole hobby a greater experience it will always remain as such. People make a hobby not the product and until we focus on attracting people rather then playing make nice with the manufactures we are going to have issues. I know to my peers this might not be a popular idea but, maybe it is time the manufactuers stay out of ROAR completely? Is ROAR in place for the industry or is ROAR for the hobbyist/racer?

Hope this helps...
Look I do not support LiPos for the nationals, but for club racing, yes, and ROAR needs to show support at the club level and the cream runs the nationals.... Not the other way around like it is currently.
But the solution to this problem is a voltage regulator and then the power source is no longer an issue.... but this seems to be to hard for all the great minds in this hobby.... But they have them for servos, go image that .....

Well, again.....I am going to have to break the news to you....
When we first started racing.....we jsut charged and went.....we used chargers that came straight off a battery.....then came the plug in timer chargers....then peak chargers.....and now we have the crazy computer things you see now like the GFX or Futaba.......
And on the maintence side.....they used to do nothing.....then people started using light bulbs....then trays came along.....and now we are up to these fancy things like the spintech or the much more unit....
Now, with Lithium batteries......you are being told none of this is needed.....well, that remains to be seen. They told us that with NimH too....
What will happen, is some geek will figure out ways to charge them better......and some uber nerd will figure out how to make a discharger that increases voltage or lowers IR....and guess what, everyone will buy them....and we will be right back where we started....with hundreds of dollars in chargers/dischargers/maintenance equipment.....while the companies laugh all the way to the bank, as this new cheaper techonology just got you to replace anything....
Please keep in mind, I am not against LIPO.....it very well maybe the next step in RC batteries.....they just are not going save RC.....they are not going to save you money....and they won't save you any time in the pits.....and they certainly not going to make you a better driver....
It's a matter of time before the companies start producing the stuff.....just right now, there isn't enough market for a high end charger, discharger, etc.....when there is.....you will see it.....they will work.....and they will sell.

While I agree 100% that Rick Wilson should never had been elected for the same reason I am 100% dead set that Mike not get elected. BOTH of them banned a ROAR member for LIFE even though the member broke NO ROAR rules not one. They even put the members name all over the ROAR website. The member was let back in when ROAR faced an attorney, Statute of limitations for defamation is not over yet either..
Mike may be good at printing out loads of crap off his PC to bring to a meeting but the "rules" / meeting notes released under his watch were not up to second grade cub scout level.

Yeah, I wonder how hard it was to print out stuff from mine or carl's thread on RCtech....
I have read the supposed summary of the meeting....not sure how 200 pages of stuff was gotten from what was passed, denied or considered....
And a voltage regulator would either have to BIG to keep the price down or stupid expensive to make it small....and even then, you will still have some with slightly better or worse tolerances.....

As for voltage regulators, I have played with these and made some cool devices to power my servo and PT independently from the BEC output of the speed controll.
Here is how they work. A 6v regulator will take anywhere from 6.5 up to I think 12 volts, and it only puts out 6 volts. It will not put out six volts if the input voltage is below that.
These devices, about the size of a power transistor(like the size of the transistors in the old Cyclone speed controls) are capable of delivering 1 amp of current. so, in otherwords 6 watts max. Good stock motors can make up to and over 180 watts of power. Therefore you would need at LEAST 30 of these hooked up in parallel.
It would be awfull big, and at about $3-5 each, your looking at a big price tag for the device.
And if you're looking to level the playing field then take into consideration the variation in motors. No two are the same. So, even with a controlled voltage output on the battery side, you will still have variation in motor speed. Not to mention gearing, tire size, weight and MOST IMPORTANTLY: car setup and DRIVING!
