Your suggestion is along the lines of reduce the amps (by limiting winds and timing) to save the motors. You say you want to keep your rip but if you cut timing and increase winds enough to reduce motor heat you will be down to the same wattage output levels as with 4 cell and the performance will be the same. No matter what we will lose some rip. The good think is that we have too much rip and can give some up without reducing the excitement of racing at all.
27T will be a novice class. 19t will be a little faster than stock is now. Mod will be faster than 19T and more drivers will be able to participate in Mod since the learning curve will not be as steep.

I'm going back to off road, it's much simplier... Hahahaha.....
Going to 4 cells can have a very adverse effect on the touring car market. Not that there's a beginer friendly car made anymore.
I'm going to go dig up the "bring back the 1/10th scale pan car" thread...

Here is another question I just realized, why does reducing MOD to 4 cells have to roll over into 19 turn or stock? Keep those as 6 cell and only reduce it in MOD ONLY.
I do agree to what Rick saidf about the stock and 19 turn timing, but I feel that enforcing a full armature also(instead of split or reduced laminate armature) and old school stand up brushes would slow these motors down a lot and keep them way cooler.

what about the mod racers taken some of it know that they might overheat the esc, blow a wind, un-solder a motor wire if they run a certain gear ratio that they know is too much for the equipment but hope to make it 5 min.
also i think you have to take into consideration that any given track can only hold so much speed and you dont see major lap time changes with with stock to 19t to mod
i was at a race this last weekend that had many US national level drivers in it and the fastest lap times in the A mains stock was 12.6 23 5:01 19t 12.4
24 5:06 and mod 12.7 25 5:10 . . .

We keep talking also about 6 cell vs. 4 cell over the last several pages. Is running or testing with a 5 cell pack not a happy medium to shoot for?

I just wondered the formula that had current drop when voltage was increased. I was not taught that one.

Winning is the ultimate goal not just finishing. Second place is first place loser.

There is no doubt that LiPo is a better energy storage medium than NiMh or NiCd. However, just because LiPo is a better battery dosn't mean its the best battery for all applications. Its failing is its single cell voltage of 3.7v. It dosen't fit well into the world of competative R/C racing. The benifits of LiPo (energy density) would make the issues we are facing today even worse.
The airplane guys are all LiPo now. The boat guys will be soon. They have much larger power requirements than we do and LiPo is perfect for them. They have unlimited motors in size weight and cost. I have a Hacker C50XL that runs great on 37V but it costs $300 and weighs almost 2 lb. No one want to strap that in a car.
Some guys want to make motors better able to survive. Neo magents and an increase in size will do it. Now everyone has to got out and design new cars to accomodate the motor. You all have to go out and buy them and all the new support equipment for them.
You tell me whats easier....re-invent the wheel or drop a cell or two?

it really is simple folks. it's the way things always have been, just new obstacles to overcome.

Sport level RTR's come from race cars, so the sport level cars would change as well, manufactuers aren't that stupid. Not to mention that they would probably start to include something like a 13t motor to keep the speed up.
If touring switched to 4cell most likely all of onroad would switch to 4cell, so that would be the new standard for all onroad cars.

The rule I like is "No More Rules!"
The current crop of "race cars" emerged from the parking lot bashers of yesterday, not the other way around!
