I REALLY want to see a number that starts with "1" - I haven't seen that since I was about 13-15 years old!

That is awesome Brian. When I used to play soccer down in Florida I never got passed 150lbs and after a few injuries I finally stopped and now I'm at 185lbs. It feels like a ton though with my bad knees. Funny thing is that at 185 I'm right at the border of also becoming obese. I'll start building up muscle around my knee and maybe get the guts to fix a torn ligament on my thigh.

That's something to look out for.

It's good to take care of your body when you've got the ability to move.

As long as you don't stop eating to loose weight; you can loose weight, but it will come back sooner than you'd like.. It's simple a matter of eating as much as your body needs.. Nothing more. combine that with some cardio sports.. loose the soda's as they use massive sugar to get so addictive. You won't believe how much sugar there is in .5 litre of coke.. roughly 75g of pure sugar.. Avoid light products as well. (learned that from the swiss Punk.. (Dafni))

I guess i don't need to tell you what to do though.. It's just.. Food is addictive..

@lutach; how tall are you?

Cardio sports is the key.. (walking/biking/swimming) running isn't the best way to loose weight because it's rather easy to hurt your knees when you are high on the BMI and give your knees a high 'load', and your heart rate isn't at an ideal zone to burn fat..

Cardio sports and less Cheesy Bacon Cheeseburgers from Wendy.. (note capitals) But MAN do they taste great..

I'm 5'10". My diet still consists of plenty of water (I love water), fruits and vegies (All I can eat ), I still love the traditional Brasilian Rice and beans w/ fish, chicken and a lean meat wee call it "Picanha" without the fat.

Lack of exercise during the winter is why I gained what I did. My eating habits haven't changed, but biking the trails in the winter is not pleasant because of the cold (not to mention snow and ice). My g/f has a treadmill, but that is sooooo boring! Biking lets me enjoy the changing scenery as I ride. I also work out (currently not because of a strained muscle) so I'm fairly big anyway. So, I'll never get down to what the BMI charts considers "just" overweight, but I'll be happy regardless.

The main thing I've learned about dieting is that you can't simply give up what you like because you won't stick to it. Smaller portions of what you like is better because you can stick with it. And those diet drugs are crap! They may work while you take them, but if you don't change your habits, you'll just bounce back when you stop taking them.

lol, I even tried talking to a hypnotist to see if they could make me hate the things I like that are bad for me. But they said that's not how it works. So much for a simple answer...

Update to the R/C Calc site:

- Added Ohms's Law calculator page.
- Updated the look a little for aesthetics.
- Added Mod 0.4 gear data for the gear calc page (for the Tamiya on-road vehicles)
- Added differential data for the Tamiya TB Evolution

is there anyway to make teh latest version more accurate?

Its telling me that a wanderer 9xl and 5s will go 101mph on my Raze, and telling me 134mph with a 600kv outrunner on 5s///

[brushlessboy16]

oops disregard that last post, it was my error, i was putting in the diameter of the tire when it ballooned out, not the amount it balloons..

sorry briang, great calculator@! :D

[BrianG]

lol, the calc is pretty accurate for the most part. The user on the other hand...

Also, was working on figuring the ratios for the new emaxx (3905) tranny. It seems that the two-speed setup is a little more involved than the original; first gear has two actual ratios, while second only has one ratio. The Savage tranny kinda works the same way (somewhat), so I'm gonna do some code changes to allow multiple ratios in the tranny drop-down for these types of vehicles. Until the code is updated, here is a quick-n-dirty diagram showing the placement of the gears and the ratios:



Single speed (stock) and Two-speed second gear ratio = 1.83:1
Two-speed close-ratio first gear ratio = 2.96:1
Two-speed wide-ratio first gear ratio = 5.08:1

Update to the calc:

- Added transmission ratios for the new Emax (3905)

- Changed the code for transmission ratios to show and calculate multiple ratios. Before, any additional transmission ratios had to be entered somewhere else.

- Updated Neu motor data for 1527, 1521, 1515, 1512, and 1509 series. Also added any newly listed motors in these series.

- Added Neu 1506 series motor data.

- Fixed bug with the picture viewer where parts of the image would not display.

You should add the Mega motors as well. I know they can go up to 74000rpms, but I haven't heard of anyone going that high yet.

[BrianG]

Added a power calculator to determine power drawn from the batteries based on pack voltage, pack capacity, and runtime. Yeah, I was bored...

Brian,

Could you please add the Muggy diff ratios in the speed calq?

[BrianG]

What are the ring/pinion gear tooth counts?

I'll add that as well as the Mega motors tomorrow...

When entering voltage and battery cell size into the speed calculator do you guys put 4 cells at 3.7 volts per cell or what?

Because as we all know that's only 14.8 volts. My Polyquest 5000 mah 4s charges up to 16.8 volts fully charged.

That is a significant difference in voltage and there for RPM right?
