Namba Voting for Modification and Additions for Electric 1/8 Scale Unlimited Hydro"

[Steven Vaccaro]

Before I vote Id like to hear the props and cons to this.

Proposal 4 - Modification and addition of rules for Electric 1/8 Scale Unlimited Hydroplane in Section 28 - Electric.

Reasoning:

Current rule:
E. SPECIALITY CLASSES
6. ELECTRIC 1/8 SCALE UNLIMITED HYDROPLANE
b. Motor Specifications
i) Power parameters for this class shall comply with class "T" specifications, as noted in rule D.1.a in this section
Note: “T” specs = Any amount and/or size of motors / 18.50 - 42.30 Volts / 12000 MaH max

Proposed rule:
E. SPECIALITY CLASSES
6. ELECTRIC 1/8 SCALE UNLIMITED HYDROPLANE
b. Power Specifications
i) Approved Motors
(a) NEU 1527 1.5Y 850KV
(b) HET Typhoon 700-98 840KV
(c) Turnigy SK3-3994 850KV
ii) Twin motors are not allowed.
c. Drivetrain Specifications
i) Either a cable or hard shafts may be used, no gear boxes allowed.
ii) Any propeller may be used up to maximum of 57mm in diameter.
d. Electronic Speed Controls (ESC)
i) Any ESC may be used as long as it is rated to a minimum 130 Amps and rated to handle a minimum of 8S battery configuration.
ii) Anti-spark resistors are advised on all speed controllers.
e. Batteries
i) A maximum capacity of 8S Lithium Polymer (LiPo) batteries are allowed. The maximum mAh capacity of the battery pack(s) will not exceed 6000 mAh. Only LiPo batteries with a cell rating of 4.20 or less volts per cell are allowed.
ii) LiHV batteries with per cell capacities to 4.35 volts or higher are not allowed.
iii) Manufacturer’s minimum discharge of 30C constant but no higher than 65C constant is allowed.

Think P-LTD, only bigger...

I'm a big NO on the "motor list"...

I was thinking the same, but would like to hear from racers first.
It seems there is a link to download the proposal, but it doesn't work for me. I havent heard much on this particular class. Im wondering who proposed this and what their current concerns are.

Yeah, that's nuts. Exactly what's wrong with IMPBA's version. You'll be saddled to what ever the tech is today. Turnigy and HET are not going to be worried about production of motors for toy boats. At least with Neu you could plead with him should he ever move on from the 1527 but at that point just call it Neu Scale hydro. Single source is bad mojo.
850kv is too low for 8s too. Why 8s? We've already established that some of these boats are starved for power.
How do you tech a battery to prove it's only 6000mah? The label I guess.
How do you verify that a pack is only 65c rated? Label again. When 65c stops being produced (cuz it will) the class will just stop running I guess.
How do you prove a cell is 4.2 volts per cell "rated"?

Anything you can't prove......can't be a rule. That proposal is a disaster. haha It's like a wrote it myself.

Something just occurred to me. I apologize. I don't even vote NAMBA anymore.

[pescador]

Not too thrilled that's for sure, I bought enough 5s packs last year to run without charging between heats.

[photohoward1]

So the rules are for like 5 Boats?

Maybe to much of this? "glue sniffer"

As far as I can tell, this is being driven by two clubs. One is RCU in WA the other in TX. Both long time scale clubs, but relatively new to FE 1/8.

The proposed rule set has all the problems we've seen in P-ltd with a couple extra added.

This rule will obsolete most of the boats on the east coast.

Not interested in P-ltd on a grand scale. Voted No.

Need to start new threads...
1) "NAMBA 1/8th Scale Limited Motor Discussion"
2) "NAMBA 1/8th Scale Limited Battery Discussion"
3) "NAMBA 1/8th Scale Limited ESC Discussion"
4) "NAMBA 1/8th Scale Limited Prop Diameter Discussion"

[T.S.Davis]

haha I wondered if you'd see that. The cost to import a brand new 370 Plettenberg motor is $1000 now. Practical solution. Seems ligit. The good news is that the ESC Plett recommends is only another $1000.

Something I find interesting about both organization is how easy easy easy it was to get rules added vs how utterly impossible it is to change or alter them once in.

Limited was a slam dunk for NAMBA back in the day. Changing or moving to the next gen? Good luck.

Randal wrote the IMPBA FE scale rules, ran a year trial for which there were maybe 3 heats organization wide, went to a vote, slam dunk. But change em? OH MY GOODNESS! THAT WILL RUIN EVERYTHING!

We're a bunch of weird dudes.

Good luck getting a bunch of “win at all cost” people together to come up with what really should be, some simple solutions! With all those recommended rules changes, it looks like there could be a wide open door for the volume of challenges to race results to increase. This really looks ridiculous looking from the outside in. And guys, I’ve been dealing with sactioning bodies in limited and unlimited boats for most of my life. You guys sound just like them, maybe even worse! These are toy boats, for God’s sake! Sorry for the critique, but this whole thing has horrible optics...
