Just in case anyone wants to review. lol

Thanks Doug

A lot of old memories their.

Hey Tyler,
No sir, that one fell too close to the Spring Nats.
A few of us are planning to make the trip later in the year though.

Good luck! You should have plenty of room to stretch her legs now if the weather cooperates.

Doug are you going to make it to Huntsville next Week?

You don't need a gas tank the size of the Titanic to race offshore (P-Limited in this case) I run a single, boring, cheap Turnigy 5800 25C in my stock Revolt and have no issues finishing/winning with about 20% (ish) left over. Even more if the conditions are rougher.

Stick with IMPBA "limits" so we can all get along.

Any of you guys going to make it out for the Nats?

Spotta. 3 of us planning to make the trip out for the NATS. So far that is. Should be a hoot. That jury duty thing sucks. Necessary as a citizen and all that but ugh. You can't un-see or un-hear stuff.

16.9 is crazy. Reeling in Truex .01 second at a time from here. Think you have the speed but just need a better line or is it a combo?

Down side to a max weight per cell would be that we would once again have a different rule set from IMPBA. Not saying I'm against it either way but something to consider I think. I'd prefer any cross over racers either way not have to re-think their stuff to go racing. It's already annoying the way it is now. They're not finding the open cap to be an issue but they also don't have any rules for FE offshore so they wouldn't see it.

Maybe that's the answer. 12k for everything and no cap if your running offshore. Just thinking out loud.

The 16.9 with the P hydro was crazy.

Other than that, 5 week grand jury duty. 5-6 cases a day, all felonies all the the time! You just can't bleach some of that stuff out of your mind.

Built a few new molds. Spent a lot of time on prop development. Being Dad every day and working on the house. Normal stuff.

It is probably time for an amendment to our NAMBA's FE rules change with the current crop of batteries. I will likely write a proposal after speaking with Brian.

What I have noticed is most "5000" cells are actually 5100 or higher capacity cells with a 5000mAh sticker. I recently tested a new battery that was labeled as a 5100mAh pack. Over 5 cycles it averaged 4970mAh between 3.7V/cell and 4.2V/cell. Overcharging conventional cell and HV cells typically add 250-500mAh per 5000mAh pack from my testing. For example charging to 4.35V over 4.25V.

While this may make minimal difference in heat racing, it does make a difference in timed offshore races and some time trial events. With all the variations in cell sizes it easy to slap a 5000mAh sticker on a 5800mAh cell. As Brian mentioned using a cell weight may be the easiest to level the playing field and it's easy to tech. High density cells like HK's Heavy duty packs may have greater power potential with a more limited capacity while a TP "lite" 25C pack may have more capacity for the same weight but cannot deliver the power potential as the Heavy Duty cells.

We haven't even been reduced to name calling yet. So.......................slacker! What have you been doing? Besides setting some spooky fast times? That doesn't count.

Hey guys,
Good topic and thread (so far). I agree we need to address it, I'm just not sure how we should go about it.

The 2-lap at Legg gave me a lot of data to work through. You wouldn't believe the power levels being pushed through the P hydro. At the same time the Q boat was basically in heat race trim running sub 8 second laps with plenty of capacity to run the mill and a mile+. P boat carried 6000 mah, the Q boat carried 6600mah.

The nominal voltage wording can go. I'm leaning towards scrapping capacity limits but adding a max pack weight. I don't agree that leaving the energy storage wide open is a good idea. That being said, I'm not making the decisions, just recommendations. I freely admit to being one of the guys who will happily walk through those gaps in the rules, I will never use the "that wasn't the intent" argument.

I'll be home next Monday, give me some time to re-read the rules and think about it. I also really want to dig into my data logs to make sure what I think I'm seeing is real.

Your doing well Ray, I'm on my third set of 4s 5000's for P , My giant power have been the best by far . the 30c and 50c have Been discharged/ neutralized and chucked .

Cheers, Jay

Prop down and stay within the mah rule limits
Cheers, Jay.

Actually I do prop down. I'm very conservative with props. My goal 6 years ago was to see how long some of the cheapest cells would last for P mono. So far I'm very happy with these cheap cells.

[ray schrauwen]

Was right at 20%.

This was at an IMPBA event, so no mah restrictions

Thanks Tom.

[ray schrauwen]

You guys need to be careful as you just admitted to violating the capacity rules in NAMBA. Q and lower are limited to 10Ah total, S and T are limited to 12Ah total. While this may be OK for club running, this won't fly at nationals or larger events. Just saying........

I'll never catch guys like you Tyler, no matter how many mah I carry. The reason I mentioned it was to be open and honest. P mono for me is more about just trying to get around the pins without hitting anyone. I never charge them past 90% and they are 25c-35c. I bought them originally before I came to any Michigan/NAMBA event because I was always running IMPBA races before. I think this will be their 6th season. When I run my 2 year old dinogys 5000's its much faster, better cells, lighter. Limited budget, I run what I have. All other classes are 10k or less. This boat is now retired to limited class racing where I'll us the same packs just only 1 of them. If I get my new p mono done Somme year, it'll be 10k max. I'm more guilty of being nasty cheap than at racing cheat.
