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

[EviLSiN]

I just read the first few pages of this thread because I just bought a 600 airframe from another member. He had it set up previously for 12s, so I want to keep it that way too.
My question for you guys is, does this setup still apply? Or are the electronics old now? My heli is fbl so I'm sure I have to get the fbl setup, but as far as motor, cyclicals, esc....are they still good choices?
Thanks

Whats the setup...??

[EviLSiN]

If you're asking about mine....it was a 12cell set up
if you're asking about my post...it's the set up from the first post of this thread.

T-Rex 600 Electric Super Pro (ESP),
Castle Creations 85HV ESC, Super. Update it to the latest software.
Scorpion 4025-630kv Outrunner, Cant go wrong.
Mikado 3012 12T Pinion - Align 5mm pinions. 15 pinion is preferable..
Castle Creations Pro BEC, Nothing wrong with that
Align DS610 Cyclic Servo's, works great too
JR DS8900G Tail servo, one of the best
JR G770T Gyro, cant comment.
Align 600 blades, still good blades
KBDD tail blades, Change them out to carbon fiber align/edge/radix blades. plastic blades flex too much. IMO
2x 6s Turnigy 3000Mah 30/40c. Better get 40-50c. longer pack life.

much appreciated

Nko....just not sure about your pinion choice there....a 15T with the stock gearing on a 4025-630 will either get too high a headspeed or need to run a lower throttle curve and run the motor in an inefficient rpm and have it running hot.
13T is ideal if using throttle curves or governor mode.

[Nko15]

With the castle you need to get a 15.. otherwise you cant rumn 2100 governd. run a 15 pinion too.runs cold. lots of power. the gearing is almost the same as the stock gearing that way.(total). 630 on 12s speed equals 1260kv on 6s. stock motor is 1220./6s

I would set up the Castle Creations Pro BEC to run on only 6 cells, not the full 12. Too many cases of it failing on 12s.

See this page for how to do that. (way at the bottom)

I'm deffinatley gonna run a 12s setup. Pardon my ignorance......don't I need a bec regardless?

[Cheetah62]

What he's saying is to run the BEC on 6s only, not the full 12s.
You still fly your heli at 12s but limit the input voltage to the BEC to avoid a blowout.

oh,ok. So the second diagram on the page is the way I should hook up the bec on 6s?

[Cheetah62]

Yes, the LV BEC diagram.

[EviLSiN]

cool, I'll look into that more. Thanks for the heads up you two.
I'm still tryin to wrap my head around alot of this electric stuff coming from pure nitros.

Hi Javier

[FlyRC4aHigh]

Not sure my PM is working so I'll post question here for rceccleston and any others that can help
Hello All

I'm building a Chaos 600E and will install in the RC Aerodyne 800 Huey. A lot of parts will not be used so I will build another 600e. as a 3d ship. The questions..
You mention using 2 3000 mah batteries, is this for weight consideration because being placed vertical up front. If more mah = more weight and that will throw the cg off?
I see some friends as well as in RC mag's that they are using 2 5000 mah batteries and placing them above the landing gear. Which one is better? It looks like the 3000 are cheaper. I will be using the new 4035-460 kv scorpion for the huey, but for the 3d ship , looking for the cheapest but reliable route. I see a align 650 on ebay cheap and Hobby king has 3 600 size motors as well. I sure could use some subbestions . Thanks Mike

Hi Mike,

If I understand the size of the fuselage correctly, due to the 6mm feathering shaft, it would not be wise to stretch a 600 to 800.

To balance a 12s helis, x2 6s >3000Mah packs for 600e and x2 6s >5000Mah packs for 700e can be used, any greater may make the heli nose heavy.

The 600 size heli's use the 4025 series and the 700 size the 4035 series Scorpion motors.

I'd recommend the 4025-550kv on a 12s 600 for a large pinion and excellent meshing, without any gear stripping.

On a 700e, a 450kv motor will allow for a larger pinion for reduced chance of gear stripping.

Regards,
Rob

550Kv motor-> 17 pinion on the stock maingear in the 600. works great.


PS: who said anything about the 4035 being for 700size?? i run a Savox 5065 in my stretched(to 600) 550..... that motor is even bigger than the 4035 scorpion

The Savox BSM-5065 560KV is only rated at 2220 watts at 60 amps on 10s compared to the Scorpion 4025-550kv at 2850 watts at 65 amps on 12s.

Yeah, thats the old version
Old: http://www.savoxtech.com.tw/bsm-5065.htm
New: http://shop.heliguru.sg/electronics/...065-560kv.html


Believe me, it has WAY more power than a 4025.. have 2 550's converted to 600, 603 edge on both, and the one with the savox has more power. Its alot more efficient too.

Boy o Boy,
I thought electric would be easier that nitro, but heck , nitro pick the cc, (simple) then fuel, glow plugs, air fuel fire, carry fuel, starter etc. messy, etc

then Electric, you got to deal with motor size, width etc, pinion size, kv , amps, ESC, BEC, on and on, Thanks Later
