Mah resitrictions

What about the HV Cells they are way above 3.70V nominal.

Larry

Yes please! Need an opinion or call on these. I see Hyperion is really pushing those.

I have 4 year old Turnigy 5800's I use in my p mono and I know they don't take 5800mah, 5000 at best. I have one set of revo packs than could be charged to higher than 4.2 except I don't have a charger to do this and have no plan on getting one. Even when the 5800s were new they did not compare to thunder power packs in almost same boat that Randall Thomas still owns. Randall still runs the old TP packs that Steve R. sold him with the boat.

Mah means much less when it comes to cheaper lipo's.

Sanctioned races, rules. Club racing is up to the club.

HV are why I was checking voltages. The "nominal" designation will likely go away with the next iteration of the power spec. That change will come when the cap is raised on the charged cell voltage. That's going to evolve when HV becomes more common than LV cells.

I've been told by multiple manufacturers that an HV cell charged only to 4.2 volts is pointless. That I'll not experience any gain. I would have thought maybe I was being sold a line of BS but I've even run some experimental cells and not found more performance so who knows really.

So, as long as you only charge to 4.2......I think there was some variation built into the rule..........then you will be allowed to run in MI. IMPBA doesn't have the nominal wording at all. Just the max charge per cell. Which is what NAMBA should be. We did add the charge voltage in there. We just didn't ditch the nominal yet.

I think of it as a transition phase. This way we don't turn away guys trying ro ready themselves for the next generation but also dont hand them some massive advantage over guys that already own a crate of cells either.

I personally feel that the spec should be like IMPBA. Max charge x cell count and that's it. Kinda above my pay grade though. Haha

Still the twins though........can't figure that part out in my head. I'm not sure length is enough of a limit to make a monster twin unrealistic.

Just because you mentioned it.

Mill and six.

I had so much fun on this course. Was able to run it with my Cheetah. Neu 1521, had 4 2s 6500 mah packs, 2 in series for 4s 6500 mah on both sides then in parallel to make 13,000 mah!!!

So much fun....

The IC guys use max. displacement, or a separate engine class with max. displacement.

I have an opinion or two on twins and FE that I'll share with you in Atl. if your interested. I don't really want to kick that turd here.lol

Very cool!

Is the tank close to empty after or how much left?

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........

[Doby]

Off with their heads!!!!

Lifetime ban!!!!!!!

We will have to have Ray branded "IMPBA Only" on his forehead.

Not sure I saw that. Mostly just guys complaining about being stuck at 10k for Q. That setup Tom mentioned was at an IMPBA event.

When it comes right down to it you have no idea how many racers if any are violating the cap. rule. How could you??

[jaike5]

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

[tjcast]

Was right at 20%.

This was at an IMPBA event, so no mah restrictions

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.

Thanks Tom.
