How to - 12s T-Rex 600 Setup On A Budget.

[phobix]

Anyone using the new 600MX motor in the original 600e? Thinking of using this motor and CC 80HV esc in my 600e.

I just ordered one, the 5mm shaft version 4025-630 I have works great but I am moving to MOD1 gearing as I started flying more aggressively.

Excellent thread!
I finally received all parts to go on 12s!
Only that my Scorpio 4025-630 arrived with 6mm shaft, so i must wait for new pinion...
Can i put 16T pinion, meanwhile?
I can't wait to try it, but i'm not sure that's good idea?

Well, after 1 month of reading this excellent thread and 1 month waiting for all parts needed, i'm finally completed my 12s heli.
On spool up my brand new ESC Phoenix Ice HV 80 simply burn out!
My setup is (was) the original setup as posted by Reccleston.
Anybody have any idea what happened?

Oh man, that's horrible! I've read so many stories like yours. Was your ESC part of the CC recall? Seems like its happening a lot with HV ESCs from Castle. Just take a look at the 700 forum and you'll see many similar accounts. Now, the only thing that's different is that most of the time, I've read this happens when you plug in the flight pack, not on spool up... but still, that SUCKS big time. Hope you get her back in the air soon!

I've been using an old but trusty CC110HV ESC on my heli now for two years and its worked out great... this is before the "new generation" of flatter more compact ESCs. Who knows, perhaps they sacrificed function for form in the new ESCs.

Hey guys, First of all I would like to thank Rceccleston for such a GREAT thread that has tought me tons about a 12s setup. I have also got just about everything I need to go 12s. This will be my first 12s system and I can't wait. I have the CC ICE 2 HV80, Scorpion 4025-550kv. Should I go with the CC BEC PRO? If so how should I wire it? What pinion should I use I've been reading and it seems the 12 tooth is the best but I have to order one as well as my motor is also a 6mm shaft! So I guess I'll have to get a 6mm pinion. Can't wait to get this beast in the air!!!

I use the BEC pro and have no problems. I wire it to a single battery (6s). That has a couple advatages. First the BEC is reliable and able to deliver more current on 6s. Second, you can plug it in with out plugging in the ESC, which is nice for setting things up with out having to worry about accidentally spinning up the motor.

About the pinion. That is personal preference. If you are a hard core 3d flyer, you will probably want something bigger than 12t. But for general sports flying, flips loops rolls, etc. The 12s works fine. It is just not going to be the smokin' high head speed that today's bangin' 3D machines deliver.

One quick tip. When running 12s on the stock gears, you have to be careful about stripping. Make sure your mesh is pretty tight

[linux_24_00]

Great reply jlharv! I think I will go with the BEC PRO then! I'm not going to be doing any Major 3D So I think the 12 tooth will be good enough for now I'm going to order the 13-14 tooth as well anyway. So is it the higher the pinion the higher the head speed? Also is there another main gear I could use to help stop the chances of stripping? Thank you for your input it's greatly appreciated.

I recommend the Kde hub and a mod 1 mail gear and pinion
Then also 6mm motor axle for sure.

Edit: straight cut gears, not slant

[linux_24_00]

What is the mod 1 main gear? I have a 6mm shaft on my Scorpion 4025-550KV So I'll have to get a new pinion 6mm. Are you talking about the one way bearing for the main gear?

[J_Rig]

Well original is 0.7 mod and could strip.
Mod 1 is "beefier" and is easier to set meshing right.
Sorry I'm away from Home just have my cell. Search for the Kde hub, it
Is made for 550/600 and uses Trex 7oo maingear, but with the same bearing as you have now.

[linux_24_00]

Thanks bro I was just checking them out. I'm going to go with the mod 1 main gear and the KDE Main bearing as well. Also the REVCO MOD1.0 HARDENED STEEL PINION GEAR, 6MM BORE . So after I have all those things then all I will need is the tail upgrade. I think anyway....lol

[linux_24_00]

I'm going to be using the CC BEC PRO, So will I need a step down for the servo's?

[jaubertel]

4035-560 is awesome too and it isn't expensive than 4025...
The stock main gear resists for me

[Luvmyhelis]

Great thread! I am coming to the point where I now have my 12s Esp platform finished. I am doing a belt stretch on it so I sold off all my new upgraded TT equipment and tail. I just stuffed an Rc-Tek aluminum boom support into it and am working on the 6.3mm wide belt and roller system. I am having Helihaven build a custom raised tail for this since I plan on swinging some humongous blades.
The Kde hub and Mod 1 gears are in place, as well as the 3 bearing main. And the hole is cut for a new 4035-630 12s Scorp so I am about ready. I was going to use the same 4025-630 you guys are but I think the 35 may provide a little more grunt at a lower hs that I need.

No Ice esc for me though. I just don't trust anything from them other than the smaller 50s I improved on to run my 6s 450 stretch helis. Plus they don't seem to work with the Skookum 720 gov so for me they are out.
Thanks for keeping this invaluable thread going!

Well just when I thought I had all I need I DON'T:arggg::face Sucks!!! So is this the right main gear even though it's for a 700? http://helidirect.com/kde-direct-main-drive-gear-115t-mod10-heavy-duty-t-rex-700n-series-p-23067.hdx

So I guess the 115 tooth Main gear will be good with the 13 tooth pinion from what I have read. Now I have to also get this http://helidirect.com/kde-direct-t700-universal-main-gear-case-t-rex-550-600e-600esp-600ef-600efl-pro-p-24223.hdx Is that the RIGHT one? As it's the only one I can find? Please let me know so I can order this stuff guys and get in the air. Thank you so very much.

Hey Rceccleston,
What is the difference in running the two 6s in series or in parallel? Also when I want to hook them up in series can I use a T-Plug that I bought to run them together is that in series? Please let me know as I am a little confused. Or anyone who knows for that matter. Thank you.

Packs in series double voltage. Packs in parallel double capacity. Its like putting two 1.5v AA batteries in a flashlight... with both batteries, you're providing 3v to the bulb. With two 6s batteries, you're providing 44+ volts to the ESC/motor. With more voltage, you decrease the amperage requirement for any given power demand... volts x amps = watts... so you see how increasing volts decreases amps. Amps, or current, is what really taxes batteries and by reducing them, you're asking the packs to deliver less current for the same amount of power.

[linux_24_00]

Understood, thank you! But how are the batteries wired? I bought this, http://www.progressiverc.com/series-t-plug-adapter.html That is how I am suppose to wire them, correct? With one of those? I hope so after ordering it and getting it. I'm almost there all I need now is my MOD 1 Main Gear and my 13 tooth pinion. Thank you in advance!!!!!!

[caralmar]

Yes, that is a series harness...but I would not use that. Instead, wire the connectors right onto the ESC, this way you never lose anything and also you reduce connectors.

This is from my 600Pro, but you get the picture. Off of the ESC, you have a red and a black. Each goes into an EC5 or a Deans, or whatever connector you want. Then, the remaining lead off of the connector gets connected directly to the other connector. Now you have a series connector on your ESC and you don't have to add any wire to do it.

In my case, I also wired a Deans connector off of the EC5 so I can power the BEC. This allows me to unplug the Deans and connect a small lipo on there so I can power the electronics without arming the ESC for bench work.

[linux_24_00]

Can I still do that as I have my BEC PRO Wired with the battery leads from the esc. Thank you for the quick reply!!!!

[caralmar]

Is your BEC Pro running off of 6s or 12s? I would not recommend running the BEC pro off of 12s. I've read several posts of people who lost all electronics when the BEC failed and passed full voltage to the electronics.

Either way, I don't see why you wouldn't be able to wire the connectors in series as I've done. Perhaps post a couple of pics of your wiring so we can better help you.

[linux_24_00]

I'm going to be running it the 6s way because I have heard about the same thing. I heard that is the best way to run it setup the 6s way! So will it be ok to run the BEC PRO Wired to the battery leads coming from the ESC? I wish someone had a wiring diagram for this whole project so I could look at it as I need to see the wiring of this thing. I want to MAKE SURE IT'S RIGHT!!!!! I do NOT want to lose any electronics!!! PLEASE HELP me out here guys I really do appreciate it ahnk you very much!!!

[jlharv]

Here is mine. I wired it off the bird so I could power it up and make sure it all worked right. Notice one battery goes directly to the BEC. The ESC is powered from the positive of one and the negative of the other, with a jumper between the two (creating a series circuit).

Always plug in the BEC first, that will power up the electronics so you can let everything initialize and do you servo checks etc. Then plug in the ESC. If you are flying CC make sure you count your beeps, if you don't get 12, something is wrong. I have lost track of which batteries were flown or not, when connecting, the voltage was low enough that it thought it was only 11 cells and only beeped 11 times. I knew immediately that those packs were already used. Had I not counted the beeps I could have ruined them.

Yes, those will work and are what I currently have installed. However if you simply want the best hub on the planet for less. Look no further than here. Wish I had seen this before I ordered my KDE.

Yes that is very nice and I wish I also seen it before I ordered my KDE hub as well. I ordered all my gear upgrades yesterday. I also ordered the tail upgrade.
