A heads up: The extractor does not do a set 5 times ore multiplication. It has 4 stages, each with a certain chance to double ores. So, if you stick 1 iron ore in there, you can get very unlucky and get 1 iron out. Or, you can get very lucky and get 16.
Also, the average ores you get vary based off of the ore. 5 is only the starting amount with the majority of ores. "Rare" ores have an increased rate, as do nether ores. Rare nether ores ( For example, nether platinum ) actually have an average of 13x.
Next, for things like Redstone which drop more than 1 item per block naturally, you will get more than 1 out when you smelt them. Redstone is 4 for example. This means half a stack of nether redstone gives you something like 18 stacks of redstone dust.
There's also a "grinder" that is ore tripling ( every time ), that you get access to a fair bit earlier.
You should be aware though: Rotarycraft and its addons eat through HSLA steel ( a special steel for RoC. )
It is a very good idea to update the version in Monster to 25z ( The last 1.6.4 version.) It should be pretty much drag and drop.
RoC working perfectly with magical crops can not be stressed enough BTW. It's great at it, and very useful. ( A fan directly powered by a single steam engine can run more than 16 farm blocks. )
Some tips:
To power a machine, start with its required "power". This will tell you which engines, and how many, you will need. ( RoC stuff is almost always each machine powered individually, unless you get into electricraft later on. ) Once you have the power, look at the torque your engines are putting out, and the torque needed by the machine, and divide/multiply to get the torques to match up exactly. This gets the speed to the highest possible, which is usually the fastest. ( Note: Friction Heater, and a few other items, should actually have torque and speed as even as possible. ) If the torque is not mentioned, it means there isn't a minimum torque. For example, if it says 32,768W and 128r/s ( speed, radians per seconds)...you can still run it at 32,768r/s and 1NM (torque).
Take your time, and do the math! It's all simple addition, multiplication and division ( using perfect squares )...and getting it wrong will make things at best not run very well. At worst, you'll blow up your brand new 16x diamond gearbox, which just ate like half a stack of diamonds.
It's tempting to make a ton of the same machine to speed things up in the mid-game for that machine. Don't. While it will run faster now, if you had spent those resources on other things ( especially better engines ), you could hit the tipping point. Pretty much all RoC machines have a speed at which they go from about 1 second per action, to 0.05 seconds. This means you would need 20 extractors with enough power to run at 1 second each to match it...meaning it's 10 times as efficient to just super-power it. ( FYI: With simple switching, the extractor reaches this at 16MW. )
Don't get frustrated with how "difficult" the mod is. It's like LEGO. It's a few simple things, that can combine together in many ways. It's actually still pretty simple.
Don't try to skip stuff when you are first learning it. The progression is designed a lot like the tutorial levels of a video game. They introduce you to 1 new mechanic at each stage, and teach you the basics, leaving you to master it. If you start trying to skip stuff in RoC, you can end up missing something while it's simple, and trying to do it when it's much more complicated ( as it's expected you know what you're doing by that point. ) It's actually pretty hard to skip though, as it's built with a fairly linear progression.
Get a rotarycraft handbook, and read it! Also, read from the wikis when you don't understand something. ( Be aware though, you are on a very old build. Lots of things have changed. For example, Magnetostatics do not require liquid nitrogen. )
Leave that magnetite in the ground! At least until you get silk touch. You need insane amounts of it for the fusion reactor ( tens of thousands ), so you want to run every single piece possible through the extractor.
