Scale

[Doby]

True to a point, but this wasn't a selective thing rather just the broad brush stroke of the statement of "damn the rules". But hey let's play devil's advocate for a minute........

So a club says "damn the rules" and decides 12S is ok for a class. Not really a safety thing as plenty of boaters that "don't race" run 12S right? So let's say there's a bad accident and someone gets seriously injured by a 12S powered boat. The first thing an insurance underwriter will look at is a way to get out of a claim. Guess what? By organization rules that wasn't a legally recognized boat, what was it doing running in a sanctioned INSURED event? Seem far fetched? Sadly it's not as I've seen and had enough experience with these bottom feeders to know that they will do anything to get out of paying a claim. Common sense would dictate that it being a 10 or 12S boat wouldn't have prevented the accident but that's not how it would work in the legal world. It sucks but it is what it is............

Well Don, as the IMPBA "Safety Rules" clearly have a Max voltage listed, 12S would not be allowed to run.

As Terry stated, the safety rules are the ones that can't be "damned".

Perhaps I should have said "Damn the rules, except for the safety ones"...would that have made you feel better?

For you to state that 12S is "not really a safety thing" is a bit alarming.

Well...if we want to follow the rules...how many of us with 1/8ths have done this???

2. Registration Procedures
a. All boats must be registered with the District 1/8 scale Chairman.
b. The District Chairman will require the following information in writing:
I. Name, address and phone number.
II. IMPBA number.
III. Unlimited name, year raced, and number.
IV. Length and beam of prototype boat and model.
V. Prototype designer and boat colors.
VI. Must submit a photo of prototype boat.
VII. $5.00 initial registration fee and a $3.00 annual renewal fee due by March 1. The
registrant will receive a District Chairman approved form verifying current registration.
Approved form must be brought to all contests. Purpose of fee-monies will be used for
high point district trophy, postage, printing costs, and other expenses incurred.
c. Boat must compete at a racing event within one year from registration.

In the advent of FE Scale, Reesor & I followed the rules(above) when nobody else really cared in FE. Primarily to set an example an some IMPBA records. Still have my scale card somewhere, however we gave up after a while when all the ugly boats started creeping into competition(not you John). Would be nice to see IMPBA FE Scale grow (no matter what the rules are) just don't forget the fundamentals. The boats should appear and operate similar to the a identical boat that competed in Unlimited Hydro competition.

I'm hoping to get back into Scale this year with my`Atlas' and a Scale`Miller High Life' hull project boat for the future. Friendly respectful competition is what I seek, not the latest monster motor overpowering another boat class. I could do that in P & Q etc. Sport (whatever IMPBA equivalent is). I'd like to be included in the loop if you guys plan on changing Scale rules first year clubs start rolling over into the IMPBA.
Should be interesting!

Back from the dead this thread.....

1527/1.5y is on the list and is the most common scale motor. It's 825kv, 40mm x 105.5mm, 4 pole and weighs in at right around 618 grams.
If there was a motor that was say 810kv, 59mmx81mm, weighed in at 690grams but had 10 poles would that seem apples to apples? So more weight and more than twice the pole count.

It's a trick question. Some will recognize the numbers.

spec the can size an voltage...KISS.

Still running 10S I assume, would not have any objections.

Can of worms. Those motors were never any better than the Neu. SOUNDED WAY BETTER THOUGH! Makes the boats sound like Turbines.

Yes Howard, but back in 2008 or so when the rules were written we were running 25c cells on 160amp esc. Some even less. Those were the weak links. Today you could run a 300amp flier and use more of the 10pole torque without baking it. In theory of course. Who knows what happens to the Plett at say 220 amps really. How it would stack against the Neu at the same draw isn't exactly clear either.

Didn't Alan, run the Plett for an entire season against the nitro boys without losing a single heat? Were there any other sparkies in that mix? Can't remember.

Point is, three entirely different motors with much different can sizes, different parameters entirely really. All on the list currently.

Today, if you want one of the Plett motors they have to make you one as they prefer to sell their newer Kima motor. The Kima is in a similar can but has fewer poles. I knew you would recognize the numbers Howard. Especially with us having recently talked about these.

The old Plett is about $850 delivered and takes 8 weeks
Lehner 2280 is about $785 delivered
Neu is about $325 delivered

The Plett does come with a water jacket. The Lehner will need one as will the Neu. Makes the Lehner and the Plett about the same investment. Go figure. Neu is the cheapo route.

A 56mmx83mm 6 pole TP is $159 plus shipping. Comes with a jacket. So only a little cheaper. 80% or so.
