Advice on electronics for eraptor

[Radio man]

Better choice: Ino-Lab HG-D750MG or HG-D760MG.

So has our handsome TS gathered enough opinions? There is no right or wrong choice, only an educated decision within your means.
You may wish to go by budget, if limitless budget go for the best.
These sort of thread will lead to people saying loose brief is better over a tight brief where in fix its a matter of preferences and both has their pros & cons

Ino Lab

yeh man ino lab is the way to go. speed of the servo is abt the same as futaba but its much cheaper. Im using them too and it works damn well.
Thanx

The electronics required to fly your heli will cost close to $1K
Buy this http://www.daddyhobby.com/forum/showthread.php?t=38739 and you have a spare heli

Thanks for the offer, but I prefer to get the electronics new, or half new.. Not all used...

Cheers

I'm using JRG770T for my Trex600N and Protos as well as my 450 size previously. The tail holds superbly even at fast tail slides. I have full authority during reverse flights. Mine are paired with 9257 and 9254. If you intend to get one and needs help pls let me know.
You know where to find me

Thank you for the offer, will definitely look you up when I encounter problems.. I will try to figure it out myself first, so I can use it as part of the learning curve for my quest to learn how to fly heli properly....

You are right in saying theres no right or wrong way of setup.. Reason for me starting this thread was to gauge how certain stuff are more popular than others and why, and also at the same time hearing from you guys' experience on the stuff that you use.. I do have a budget to work with, but if I have to stretch it abit to get more value for money parts, I am willing to stretch it, but definitely not budgetless..(i wish)...

Thank you all for your comments / recommendations.. I am sure those who are new like me and jumping into the eraptor wagon will hopefully find this thread useful...

Cheers

Hi all, just gotten myself a e550 wif extended boom (to run 600mm or 610mm blades), and was wondering wat kind of setup will be suitable for it. As I am just a beginner, and the electronics used will most probably be for sports flying, please advice me on the electronics to be used. Budget wise, not very big

Below are some ideas that I am looking at..

Motor - scorpion hk4025-740kv
ESC - CC85HV (or is the stock BLC-65A ESC enough?)
Cyclic Servos - HS5625MG or HS5645MG or HP-DS20FMD
Tail servo - HP-DS20GMD or 8900G or ???
Gyro - GY401 or JR770T or Solid G or ???
BEC - Turnigy 15A bec (from Genexis erpator build thread)
Batts - 2 x 5s 3300mah Zippy batts

Do leave some comments on the above setup and if possible and recommendations.. My intention will be that hopefully the above mentioned setup will enable me to move to intermediate level.

Thank you all..

Know nothing about power system for big electrics but...

Cyclic servos- skip the 5625/5645, they are "not here, not there". Go for either the 635hb(one step down) or the 7966hb(one step up). The 635hb are decent enough even for most general 3D flight. I still have got one in my raptor with almost 600 not so gentle flight.
Ino-lab servos, the wire solder joints on the 760mg(at least on mine) are not even gooped. IMHO, that is not how a $90 digital should be. Wonder what goes inside the servos. They do work ok though.
There is definately difference in feel between the more expensive servos and cheaper ones, but the question is, how much will it affect you. E-raptor is eccpm? TBH, I suggest you to really spend here.

Tail servo- 9254, BLS251, 8900g. They all work good. Might want to check if 8900g will fit the raptor rudder servo mount. Note BLS 251 does not work with 401 or 770gt.

Gyro- Solid-g. I love mine. Really very consistent piro rate and holds superb. Super easy to setup with the g-view LCD. No guessing of numbers or settings. Stops hardness can be adjusted to your preference. Only 1 problem- You need a G-view for that which will cost another 60bucks or so.

BEC- If you are on a tight budget like me, take a look at the $29 dualsky vr-8l 8 amp regulator. Linear mode is supposedly quieter. 5v to 6v adjustable. Failsafe switch. Nicely covered solder joints. Big heatsink. Dual input and output connectors. If you are afraid of the dualsky brand, you can always go for the Flightpower labelled version which I think is on discount now at MBRC.
I did a short review here...http://www.rcheliresource.com/review...-8l-regulator/

Hi Baby zyklon,

Thank you for your input, especially the part on the servos... I think theres a typo on your side when you say eraptor is eccpm, I think it should be mccpm, where the servos work individually, thats why a need for good servos... As for the gyro, does it mean i gotta get a g-view thingy for the gyro to work, or is that optional?

The more comments is being added, the more I understand how you guys go about choosing your stuff.. Thank you all and pleas keep the comments coming!!

Cheers

Hi,

Eraptor is 90 degree eCCPM stock and can be converted to 140 degree eCCPM.

[chasers]

Many apologies, just read the manual and its eccpm... Only elevator servo works alone, but aileron, both servos work together...

You don't need a g-view for it to work, but a lot easier to set up with one. Can borrow one at the field from your friend if they have it. Without the G-view, you will have to use the blinking led and be limited to just the basic settings like L/R limit, servo type, direction etc. The g-view allows you to enter the advance menu and also change the model type. IMHO, the raptor model inside the solid-g is very well done, so all you need is probably just to change the model type. Different model type will have different pre-set settings for the advance menu.

No lah. The elevator also work with the change of pitch. I tink u need to re-read the manual again. Pg23 n 24.

Tot on page 23, it says "..only 1 servo works while elevator input is given if using 90 degrees E-CCPM. But with 140 degrees, all 3 servos work at the situation." And one page 24, it shows one servo moving for 90 degrees swash..

Mine is 90 degrees, that why I said only one servo is working for elevator.. Correct me if I am wrong, this is my understanding from the manual, which is making me think if I should get a more powerful servo for the elevator and the other two servo identical for the aileron..

all three servos should be identical, else you get weird mixing with collective input.

The elevator servo tilt the swash to give elevator. Aileron servos tilt the swash to give aileron. The 3 move up and down together to change the collective.

Noted on the using of identical servos

The elevator servo tilt the swash to give elevator. Aileron servos tilt the swash to give aileron. The 3 move up and down together to change the collective.

Yeah, thats what I understand too from the manual....
