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

As you draw current out of a battery (any chemistry), the voltage across the terminals will drop. Higher C-rated packs have lower internal resistance and are also able to maintain a higher output voltage under a given load when compared to lower C-rated packs. This drop in voltage directly affects the headspeed because the motor speed is proportional to the voltage coming from the ESC (and ultimately the battery).

Nice clear explanation. Thank you very much.

a few more questions ; when it comes to soldering the Hercules BEC, it is the same as other BEC right ? meaning I solder it to the same deans that goes to my ESC ?

then how do I set the voltages on the BEC. I see the dip switches and the box diagram next to it but I dont get the diagram. When the box is white does it mean the switch is in that position ?

and about the 6mm shaft for the 4025-630; I would need a 6mm pinion for it then right ? who carries them. Ready heli doesnt !

[azheliguy]

Yes you can solder to the wire or to the Deans.
ReadyHeli does have the 6mm pinions.

doh ! I was just looking for the mikado ones forgot about revCo. thank you.

ok.I searched the thread but no mention of what dampeners everyone is using with this setup. stock grey or black or something better ?

[SkinWalk3r]

and who makes the 3x10x4mm bearing for the tail mod ?

[tonyblade]

Skinwalk, I would recomend buying a voltmeter to make sure the settings are correct on the Hercules . I thought I had the dipswitches the rightway round but just to make sure I put the voltmeter on and am I glad I did!! I would of fried my electronics. I think even Hercules recomend to check it with a voltmeter. I would mate. Tony.

[SkinWalk3r]

tonyblade; thats a very good idea. wilco :thumbup:

[strokermtr]

I've search everywhere! Even the sites suggested a few pages ago. Help! Have my funds all put together now and no luck.

Protek makes one - you can get it at AMainHobbies:

I started with grey, now run the black (I was concerned about a boom strike with doing tictocs). I have some KBDD dampers waiting in the wings for when I trash the black ones.

Hyperion sells a rebranded -630 with better bearings - you can get it here:

[strokermtr]

Have you or anyone you know tried this Hyperion motor? Great price.

[strokermtr]

Nevermind. It's out of stock at the link provided.

[azjeff]

My heli is built per this 12s setup. I have read through most of this and have not seen a run down of DX7 settings. Anyone using a DX7 are what are your radio settings. I already have a lot of them but want to double check everything. Hopefully, I did not miss a page with this on it. Thanks

I just found a set made by Align for the 600 that has the bearings - part # H60087

Mate I have the hyperion in mine. I have been using hyperion gear for many years now with little fuss. Try:

is it normal for the WR Hercules to get quite warm from just being plugged in ?

[GB ian]

Can anyone give me an idea of "normal" motor temps?

4025-630 12T 12s 3000.

I have yet to even maiden my 12s600e but the motor seems to get remarkably warm even when spinning up on the bench with no blades.

Any advice would be great.

Thanks.

Have you adjusted your timing to 5 and frequency to 'outrunner' mode??

[adroc3905]

Aww man. I don't want to hear that. I just bought one to replace the CC BEC Pro.

I wouldn't worry about everything you hear.

I have over 300 flights on my original CC BEC Pro without any issues.

If using a 14t pinion, what % throttle should I run at please? (im worried I may spin the blades too fast)

With 13T in fixed end points you'd see 2250rpm so 14T would require either 'high gov' or 'set rpm' mode.
