Trex 600 Electronics Selection Suggestions

[tcast305]

I've started a new thread since the other flight thread has gotten side tracked.

So far I plan on using the Futaba 9451 for cyclic ( http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXCTS2&P=ML ) .

For gyro I'm still undecided gy401 w 9254 or gy611 with 9251. From what I heard the gy611 will feel more locked in, however I dont if its worth the extra 130 or so for that.

On the RX I was planning on using the Futaba R319DPS RX, but finless called it "dial a crash" :( , however I have read reports that it works just fine??? Some others just suggest R149DP rx.

Also far on the esc and motor, I plan to use the stock ones that come with the kit.

I think starting a new thread for this topic, was exactly the right thing to do......we need a thread like this. ;)

this is what I'm going to be installing in my 600:

Gy401 with 9254 on tail. I'm not a 3D pilot yet, so I'll upgrade the gyro when necessary.
Hitec HS5945MG servos on cyclic (http://www.hitecrcd.com/Servos/hs5945.htm)
JR S770R PCM Reciever
Stock ESC, BEC and motor.
Forgot about the two Thunder Power 4200mah 6S2P Batteries ;)

Hitec HS5945MG servos on cyclic (http://www.hitecrcd.com/Servos/hs5945.htm)


HOndaJunkie,

That servo has more torque than the futaba however its faster. Is there a min speed and torque required for the trex 600? That information would be helpful.

[H0ndaJunkie]

The minimum speed would depend upon how you intend to fly the heli......they don't put stipulations on stuff like that usually.

There is probably a minimum torque requirement, but we've both got that covered by maybe 250% of the requirement!

I didn't buy these servos specifically for the 600.....I had the whole setup in my Raptor 60V2.......I certainly didn't want to buy new servos, especially when I paid $90 for each of these.

[Finless]

I dont know that there is a minimum speed for a 50 sized heli but like any 50 sized heli good digital servos with decent speeds (.14 or below) should work just fine.
Myself I will be using the Hitec 6975 on 6V.

My setup will be
GY611 gyro with tail servo
HT 6875 servos
Futaba G3 rx :)
stock ESC, motor, etc and Align 4400 pack

Specs are good on that servo, however it has Karbonite gears not Metal gears. Do you already have them, thats why your using them?

You said that you decent speeds matter, but what about torque?

What you think about those futaba servos 9451?

[H0ndaJunkie]

121 oz is way more than any 50,60 or 90 size heli requires. They're fast too, so they look like a great servo for the 600 to me. ;)

I would say anything with about 76 oz torque and up will be fine.

Yes I know they are carbonite and yes I did have them already. I know 2 people using them on a Trex 600 now (Andy Yu being one) so they should be fine.

If I didnt have them already then I probably would go with S9252's as they are .91 torque and .14 speed. I have been using this servon on all my nitro 50's and my Vibe 90 and have had nothing but a good experience with them.

I'll be using 3x 9451 Futaba digitals, a Gy-611,
the R5014DPS that came with my 12ZH
( crossing my fingers there, with all the troubles I've heard folks having with them ).
a 6s2p 4400 Align pack, and all the standard BEC/ESC from Align.

Have you heard of anything with R319DPS RX on heli's?

Thanks

[tcast305]

Also on servos with metal gears, do they tend to wear out fast? Would karbonite gears be better as they don't wear as metal gears? How would they hold up in a crash.

Thanks.

[supertrex2]

My Servo speed is .19 sec

Im not a 3D pilot. But I will definitely try to do inverted hover someday.

Since I'll be using S9204
I think its good for regular flying.

Rx R149DP 72MHZ
GY611

I Might buy the Airtronics 94758 if my S9204 gives me a problem. :) But as far as my research goes about this old school servo. They are very tough and reliable.

Bob

Bob, your not the first to say they gonna use 9252, however I see they are not rated for 6v?

Bob, on a heli like this would you choice metal gears vs karbonite gears. I've read that metal gears wear faster? Is that a non issue now?

[H0ndaJunkie]

how on earth would metal gears wear faster than plastic (Karbonite)??

[king kong]

Some of the plastig gear servos, provide more than enough torque to do the job. Metal servos also tend to develop more slop than plastic gear servos.

[Finless]

This is true and why some people dont like metal gears. The metal vs nylon gear arguement has been around longer than I have! Me personally I dont care and for 50 sized helis I look more at speed, centering performance, etc before I choose a servo because of its gears.

9252's have worked fine for me for a long time on both 4.8 and REGULATED 6V setups. I personally like the servo for it's price. If money was not a worry then there are many good servos to choose from. For instance, the Airtronics full sized digital is a NICE servo too (I forget the number) but they are $100 a pop.

Bob

So which one would you choose the 9252 or the 9451 if you had to buy? The are the same price, so price isn't an issue.

[tcast305]

I've finally decided on gy401 and 9254, for my trex. I could get the gy611 however I think it would be overkill for me, since I dont do any 3D yet and I'm sure by that time there will be a gy621 or something by then. :lol:

[Hangarace]

What about the R146IP futaba PCM reciever?

[Finless]

What about the R146IP futaba PCM reciever?

While the RX might be OK I dont want to trust this size a heli to a single conversion RX. A 149 etc I think is better.

Bob

[Rick Rotorhead]

Hi Bob, I've got the 146ip on my shopping list for my 450SE build, should I really be going for 149 instead then (ie: if a 149 is good enough for the 600 then why not in a 450SE?) Also, could you please explain' single conversion' (I'm returning to R/C after a 15 yr break and in those days a Rx was either AM or FM hee hee, I understand about ppm vs pcm and am ok with that concept, but not this single or duel conversion I see mentioned around).
Regards, Rick

[tcast305]

Finless,

I'm thinking about the hitec servos for cyclic. I've been reading about 9451 and it wasn't designed for helis. The futaba 9252 are, however they are not supposed to work on 6v even thought it will.

I see your going to use the HS-6975HB on yours. Which one would you pick the HS-6975HB or HS-6965HB? The HS-6965HB are slightly fater, but a lil less torque.

What you think?

[skew]

The 9252's will be fine on the align bec. It puts out 5.8v, the 4cell rx battery in my raptor stays around 5.5-5.6volts. There is hundreds of post on this on RR they have been ran for years on 6v regulators. The 9252's are tough to beat for $60 ea.

Yeap, I saw your post in the other thread about the 9252 at 6v regulated. But what do you think of the hitec's? I believe Finless is using the HS-6975HB on his for cyclic. I was just comparing both to find out which one to get.

One of the reason I was looking at the hitec too, is because they come with karbonite gears, the futaba comes with regular nylon gears, and the hitec is faster and more torque.

Also where can you get the futaba's for 60 bucks? I thought they where like 74 dollars.

[pth3k]

Have you heard of anything with R319DPS RX on heli's?

Thanks

Only a couple "DIAL-A-CRASH" references here & on RR. I think Bob mentioned dial-a-crash also. Kinda scary when you think about it.
If a problem happens to more than one person, there probably is some
sort of issue going on. I'd hate to be one of the unlucky ones. I tend to
have multiple receivers floating around that use crystals. I also have a
couple sets of RX crystals for my two favorite channels. I do have a synth
module in my 9CHPS so I can switch back & forth ( but only if I have to
because someone has the flag for ch 43 my primary ch.). But now that I have the T12ZH Switching FREQ's is just a matter of touching the TX antenna to the RX antenna & selecting the new freq in the TX. I just wish Futaba had a G3 rx that weighed what the 146i does. That would be cool.
