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

Speaking of IW. Can someone on the site let an admin know that reCAPTCHA system is down and needs updating. This is the system that requires you to answers questions to verify you are a human being and not a machine. Until it is updated no new people can sign up and those who have forgotten their password can not recover it. I sent them an email from outside the system but it was never acted upon. A similar thing happened here at OSE awhile back, but Steve fixed it right away.

I truly feel badly for all the NAMBA FE guys that got hosed by that BS rule, my only suggestion would be to as soon as possible submit a new set of rules for 1/8th scale FE. With that being said I have been doing a lot of research in regards to updating the IMPBA 1/8 FE scale rules to increase our motor options and after building and racing a few of them along with conversations with other FE guys I think a simple "can" limit will do well. Easy to tech in the field and a motor will only produce a certain amount of watts based on it's size, limit the can and you limit wattage potential. Here is a post I made in that regard on I/W-

I would probably guess that when the rules were written then those were what was available. I have been on this for a bit and agree limiting motor can diameter and length might be the best option for the IMPBA in opening up motor choices. With FE the math is simple- volts x amps = watts = horsepower and you have 2 choices to get there- more volts and less amps or more amps and less volts. Higher amperage is more heat and heat is the killer of electronics, the 9 & 10S scales I've done run well below max temps that I'd want to see. With the ones I've built or helped build I found we need roughly between 2100-2500 watts to adequately power a heavier FE 1/8 scale reliably in the 55-65mph range. I think by limiting the can size we should be able to keep a decent lid on the wattage potential. Since the Lehner 22 series run 44mm diameter, are numerous and already legal we should probably consider a max diameter of 45mm. As for length a Lehner 2280 with optional fan is 120mm and currently legal so we need to be around that as well. As for Plettenberg I found a series called Dinator and at a 45mm diameter with smooth can looks viable but the Plett HP 370BM/50 A1 S which appears to be the motor Mike referenced is problematic with it's size. How many are actually out there currently in use? If it's just one or two then it might need to become a sacrificial lamb for the sake of growing the overall motor options. All of the current 40mm 15 series Neus will fit in this 120mm x 45mm range as will the Leopard, TP and SSS motors. That right there opens things up to more options and lower cost as well and if anyone knows of other brands that would fit within this range please feel free to chime in.

I honestly feel that a 56mm diameter motor has no business in an 1/8th scale FE because of the wattage potential. After the above post I found a few other motors that would fit into those can guidelines. Again simple and easy to tech "in the field".

I want to pet that " Magic Unicorn".. It's a shame that very few lights are coming on @ IW.��

Man, I live near Portland OR. I'm scared of magic unicorns! They're mean out here!

Don,
Don't forget the HET typhoons, there's a 1527 equivalent in that line as well.

Well, I guess this about sums it up. From the I-Waters discussion of the same... I guess if you don't tech, it doesn't matter then...

Ah, the good old days! Don't ask, don't tell! The ignorance is strong with this one.

Sorry about all the posts guys. I just need to hang out with some people who still like me.

They put you in a bad place Brian. Sorry about that. I hope they give you the tools to attempt to fix it. Didn't know that about the Magic Unicorns...lol

I know this is the NAMBA thread, but I think there is enough relevance to share. I started this when the IMPBA discussion was hot and heavy. No magic here, just a collection of information that is formatted in a way to compare easily. I am struggling to find any others that fit in the general size of 45mm diameter and 111(ish)mm length.

Hi Mike:

Is IMPBA looking to expand the motor options?

Didn't know that about the Magic Unicorns...lol

OMG!! I thought Brian was just joking, but I'll be damned if there isn't actually a FACEBOOK page regarding this!

Hi Mike:

I guess you could say we are collecting information/data regarding the 1/8 class. There have been others that have suggested there needs to be some more cost effective alternatives. Given the current situation with NAMBA I thought this was some helpful info. Feel free to move, delete, or use as necessary.

Who knew? Well except Brian.. lol. Good work Mike! Thank you sir!

The SSS line has motors fitting the suggested 120mm x 45mm range limits also. Even with just these we've more than doubled the choices with lower cost options as well. And Mike is right, we might want to move this part of discussion over the IMPBA page.

Let me propose that NAMBA should not change the existing FE 1/8 Scale rules, but establish two classes. “Unlimited FE 1/8 Scale” under the rules as they have always been, and “Limited FE 1/8 Scale” under the revised rules. I know that NAMBA doesn’t really need another class, but having these two classes could give everyone what they want.

Jim,
I've been looking at that as an option, it's not a bad one. It actually makes some sense, it would give the boats built under the new rule two places to play. I've got lots going on offline with this. I'm doing what I can. There's certainly precedent for it.

Hey Newland! Do you want your job back?
