trex 600 nitro wiring!

[WAZZER43]

Hi everyone! Complete numpty newbie here and in need of some urgent advice. Wife bought me the 600 nitro super pro combo, having already flown (badly!) a belt cp thing. Built it very, very carefully and hunted around for build tips etc. Now comes the wiring. Got a 7 channel futaba 2.4ghz tx, the kit came with the two in one regulator and a governor. So far got the power into the rx but where the bl**dy hell do the rest of the wires plug in? The manual says channel 3 and 7 for the governor, nothing indicated for the 2 in 1 regualtgor apart from "receiver" and then ch2 aileron, 3 elevator (oops, thats two for that channel!), 4 throttle, 5 seems to take the rudder and futaba gy401 gyro which also has a cable to channel 6 and finally, to round it off, there's pitch to ch 7 (but doesn't that already have a plug from the governor in it?)!

Have I run out of channels or am I really a serious dope missing something really obvious?

Some guidance as to how to get all the various remaining plugs into the last 6 sockets would help me enormously. Even three beers didn't clear my head enough for this one.

Wire it like this:

Receiver Channel:
1 - Right-side aileron servo
2 - Elevator servo
3 - Governor (the throttle servo plugs into the governor)
4 - Gyro (the rudder servo plugs into the gyro with a 5.1v stepdown in between)
5 - Gyro gain (will probably just be a single wire from the gyro (signal))
6 - Left-side aileron servo
7 - Governor RPM (ie a wire from the governor)

Now of course you've got the power lead from the 2-in-1 to go somewhere, but you're out of sockets on the RX - what I do is use a Y-lead to plug this into ch-7 together with the governor RPM, but it can go in any of the RX sockets you like.

Don't forget the 5.1V stepdown wherever you use a servo that can't run on 6V (ie the tail servo, and in my case also the throttle servo).

Hope this helps

Jim,

Off to the model shop now for the y-lead. Thank you for your help - I have no doubt that I will be visiting again when I trash the 600! Think I will spend a few years on the sim first and invest in a huge set of training gear.

Have you got a local club you can visit. There will be someone there who can check it over etc. to make sure everything is in the right place and working correctly.

You sound like your doing all of this on your own, and although a belt cp can still be dangerous, its nothing like an out of control T-rex 600. I would strongly recommend going to the bmfa site and looking one somwhere local to you

Tony,

Just discovered Preston Helicopter Club a few days ago so I am going to join up with them, pick their brains and fly with them because I know I will get so much more out of the sport if I do.

The other problem is that I have read DemonJims reply and then looked at the rx (Futaba (R617FS) and I still seem to have a problem (although I am definitely missing the obvious, I fear) that if the power goes into the first slot, that only leaves me 6 others for all the leads and DemonJim has the right hand aileron going into ch 1. B*gger me!

I do have someone who has been flying and bulding helis for about 20 years to check it all over and set it up for me but I am so desperate to try and complete the build myself before he does that and it has taken me about 20 odd hours to meticulously work through the build manual and online build guides to ensure that I have it right.

Call it a mad challenge or what but I am stumbling at close to the last hurdle........

On DemonJims istructions, do I still feed the power into ch 1 too, please?

Sorry thought I'd already answered that:

....and thats where I have gone wrong!

I have mounted the battery unit that camewith the tx/rx under the nose cone and the second battery pack from the 2 in 1 on top. But I now appreciate that the 2 in 1 unit and battery pack is all I need, not the second battery that came with the tx/rx. Now you realise why I signed upto this forum because I would not have a clue otherwise. Two batteries - hence the extra cable and plugs everywhere!

Thanks agan for your help. I'm just releived I decided to stick with the day job too..........!

Yeah, forget about that four-cell 4.8V NiCd that came with the TX - the 2-in-1 completely eliminates the need for this RX battery, by regulating the LiPo voltage down to a solid 6V for all the servos etc. The 1900 7.4V LiPo that goes into the 2-in-1 powers everything, ie all electrical gear AND all the servos so a steady voltage is a very good idea.

The 2-in-1 regulates down to 6V, which is why I highlighted the need for a stepdown in between the gyro and tail servo - this is very important as I'm sure very few tail servos will run properly on 6V. If you forget this you WILL burn out a very expensive servo (eg if using a Futaba 9254).

Cracked it!

How good is it to be able to post on a dedicated forum like this and receive such helpful and speedy responses? Brilliant!

Thank you everyone
