Electrics for 600E

[Rotor Ruiner]

As some might know I just finished off my build of a Trex 450 nitro hybrid heli. I decided to quit smoking just after I had completed the heli and it has now been 2 weeks ! As a reward, my better half informed me that I can go ahead and get a Trex 600E :D As long as I don't start smoking again I get to keep the 600. If I fall off the bandwagon I was told the 600 " WILL BE SOLD IMMEDIATELY! "

This brings me to my question. How big of a battery can you run with the stock ESC and motor. I was planning on a 6S1P 5000 mah flightpower pack. I do not plan to upgrade the ESC and motor for quite some time, if ever depending on performance. I have heard of people running up to 10S packs ( aftermarket esc and motor I think ). Will the performance with the 6S1P and stock electrics match the performance of a Trex 450 SE or even better it. I understand a lot a variables have not been addressed in this post. But with all things being equal, I need to know what the power to weight ratio compared to my SE will be before I go ahead and pick out a new charger and batteries. Thanks all.

Congratulations on stubbing out the cigarettes :cool:

I'm no use to you on these mega battery heli-s, I intend to stick with 3S size machines, those big batteries just worry me, but I suspect WiscHeli- and others here will be able to offer some assistance with your questions, good luck with your new helicopter, please keep us up to date with your build and charging equipment etc....

Cheers Ralph

These are the servos that I am thinking about using for the cyclic. Has anyone used these or had any experiences with them ?

instead of the 600E take a real close look at the Trex 500 it flys just as good as a 600 and the Batterys are alot less a good pack for the 500 is a 18.5v 5S-3300 or 3700 with a 600 you need 22.2v 6S 4600-5000s ,,, compare prices :eek:

if you want a 600 i would go 600N ,,, I sold a NIB 600E to got a 600N and then after the T-500CF ;)

my 500 set up is
3x DS3421s
G770-3D/DS3400G

600N is and i would do a 600e same way
Futaba S9452 X3
G770-3D/DS8900G

sorry i dont like Hi Tec i remember in the 80s-90s when they were called off brand servos and still are to me :rolleyes:

[Rotor Ruiner]

Thanks for the input, but I really want a 600E. I have wanted one since day one. The prices for the batteries are steep and that is what has kept me from owning one. Now with my better half on board, I just have to go for it.

I appreciate your input on the cyclic servos. I also prefer Futaba equipment above all others. I was looking into the Hitec because I run the 65MG's on my 450 and really like them.

[WiscHeli]

If your heart is set on a 600E it is a good machine and yes use the S9452s strong fast and MGs .. i didnt like the batterys so i went 600N pay fuel in time not all upfront in batterys ... i am seeing the 600e at full packs out proforms the 600N but 600N will stay strong though full and longer flight .. its all personal whats ;) ... the S9451 i have are now S9452 but they were to go in my 600E till i sold it ;) get the JR G770-3D/DS8900g combo its better then the F Gy611 gyro

[Rotor Ruiner]

I've figured out what I'm going to use for the cyclics - 9350's. Are they overkill ? Probably, but fast, strong and have MG. I was looking through my parts bins and found a 9350 that was used for the collective on my C5 for about 5 flights before I switched it over to EMS (ccpm). That means I only need to buy 2 more. I was planning on the 7703D/Servo just because I want to try one out and I like the metal case for the gyro and servo. You find that they really are that good ? Better than the GY611 ?

[WiscHeli]

the 9350's are over kill more for a 90 but yes will work great ... i am looking at the S9350's or the DS8717s for a T-700N ... from what i am seeing yes the 770-3d is better .... working great in my T 500 withg a DS3400G :D

First of all, I applaud your decision to quit smoking. Best of luck and I hope you can stay healthy.

I have a T-Rex 600E and it's a great machine. It's big, stable, and fast. I am back with the stock motor (my Z30 suffered too much crash damage last summer) and a 10T pinion. I run a Castle 80 Phoenix with 6s5000 batteries and see about 2000 head speed.

I use the HiTec 5625MG servos, with a Futaba 611/9256 on the tail - all controlled by a DX7.

This stuff all works very well and can take you a long way.

I also have a new T-Rex 500. I only have two dozen flights on it, but it's a great little heli - very much like my Lepton. The 600 is much bigger and the physics of flying are very different.

Hope this helps,

Ron

The 600 showed up on Monday ! All I have done is open up the box and check out the goodies inside. I also ordered all the metal head upgrades, not that I needed them but they look good and don't break like plastic. The kit is a FG one as I got a really good deal on it. After looking into the carbon frames I decided to go a different route. I ordered a Rotorworkz, Heli Freak Edition carbon frame. This frame is designed to use Futaba 9650's on the cyclic instead of full sized servos and places the motor on top of the main gear. Now if I could just find some metal gears for a 9650 somewhere ( I don't think futaba makes them ). If this frame doesn't work out I still have my back up plan of using the FG one with 9350's. If anyone here has any insight to this frame, I would love to hear it. Now just have to do more overtime and save up for the rest of the electronics.

What kind of basis are you saying the JR 770-3D gyro is better than a Futaba GY 611? I think that is inaccurate. Both Gyros perform exceptionally well. The Futaba is easier to set up and offers more set up options, such as travel adjustments for both directions. The GY 611 has a very good feel with minimal setup, and although the 770 excels at delivering faster piro rates and harder stops, fine tuning them to feel right and deliver consistent, smooth performance is more time consuming with the JR. With the JR, you must also be cautious of trying to fly with the gain too high; it can have very violent behavior. I would say either is a good choice, but I do not agree the JR is better by any means.

As for the 600E, I think you will have a blast with it! It flies very well, is very capable, and the battery price is really its only setback. I have the Rotorworkz frame on our 600, it works really well. The 9650 servos are good, but you cannot get metal gears for them and they do break (My 500 went in last weekend, and it took out all the gears in the 9650s). I am using Hitec HS 5245MG's, which have metal gears, and they have worked very well.

[Rotor Ruiner]

Thanks for your input Aaron, appreciated as always. I do think I am going to go with the JR unit just to have something different from all my 401's. A 611 for me is total overkill, I cannot fly well enough to warrant buying one of those.

I was wondering if the torque tube conversion for the tail will work with the Align carbon tail boom. Every heli I have seen with the TT is running the standard aluminum boom. Nothing wrong with the aluminum, I just like the look of the carbon one. I think it will match the Rotorworkz frameset nicely.

If Futaba would make metal gears for the 9650, I bet they would fly off the shelves.
