No 3-in-1???

[bullaculla]

I have an upgraded CP pro. After deciding to NOT spend anymore money on this thing, I just ordered eflites 370 brushless and ESC. :roll:
and now I'm going to get the G90 too.

So my question is:
Can I get rid of the 3-in-1 if I buy some sort of mixer? It just seems like extra weight since i'll have a good gyro and ESC. My blade is heavy enough already.
Has anybody done this? what exactly would I need. :arggg:
I already have the GWS DD tail, superskids, MH main shaft, MH spindle, century main gear w/auto hub, and the MH alum head. Not to mention all the stock parts I broke and replaced. I got rid of the plasti blades. too heavy and too many chopped tail booms.
Theres no turning back now. I've invested too much time and money to leave it alone. please help.
Thanks! :D

I have been thinking the same thing. Now that I have a new DX 7 Tx and will soon have the AR6100 Rx (well when ever it comes out, looks like it is delayed). I also have the suggested brushless set up with the suggested ESC and the G90 Gyro.

I would also like to get rid of that 3 in 1 but I am not really sure what is needed.

From what I can gather you will need a brushed ESC and that brushed ESC will need to have a BEC (battery elimination circuit) built into it or you will also have to get a BEC so you can power everything.

With all that said, I have not found one yet that I like and that is economically viable for what it is. I am figuring I would like to spend $25 or less.

I know there is a really nice one out there that would work great but it is expensive, I have not found one that good but less expensive yet.

Let me know what you find, I am very interested as well.

Thanks,

Get an ESC for the tail, use the main BL motor ESC's BEC for juice, AVCS gyro will make the mixing unnecessary. I am currently only using 3in1 for TR ESC and electronics BEC with the gain and mix pots turned off. I figure this is about as light as installing a separate ESC for TR by the time you weigh in the wiring and everything to hook it up. :)

OK, to my surprise I was able to pick up the Spektrum AR6100 from the hobby store today. Can anyone suggest a brushed ESC for the tail?

I totally forgot that the Eflite ESC has a BEC so one will not be needed.

I can’t work on it now, but I am really excited to set up my heli with the DX7 set up. I am really hoping it will get rid of my glitching issues.

Thanks for any help.

Good luck with your set-up. Your glitches should be history when ya get that DX7 fired up! :wink:

Yes you can totally get rid of the 3 in 1 if you have a computer transmitter ( not the stock POJ). With a HH gyro once it is in HH mode and setup correctly you will not need any special mixing, although it will "kick" on take off. There are plenty of brushed ESC under $25 that will work for the tail , a few examples:

I did a quick Google and came up with those.

the lighter the better, the pixie 7 by CC is a very good esc.

If you are running a brushless main motor then the brushless ESC will provide the BEC so your tail ESC should not have the BEC connected to the receiver or you will have magic smoke. All you have to do to eliminate a BEC on a speed control is cut off or remove the pin on the center (RED) wire going to the receiver plug.

you will need a 6 channel receiver, lighter the better. The AR6100 is probably one of the lightest available for these helis and with the 2.4 Ghz Spektrum it just can't be beat especially with the myriad of features available. Might be a bit expensive if you don't have the DX7 though. Any decent computer transmitter 7 channels or more will be able to do any mixing necessary to get the CCPM working correctly, and have an extra channel for extras. Also you could setup a rate gyro to work and use the TX revo mixing feature to make it nice and smooth at take off. You can use the stock receiver with a Futaba or Hitec Tx ( some Airtronics) and use all the TX features, but the stock Receiver isn't a very good one and has glitching issues which might be exasperated by the higher powered new gear.

So all in all if you already have a brushless esc and motor, a DD GWS motor, a HH gyro and lots of upgrades then you only need a couple of things.
Tail ESC, Computer Tx, 6+ channel Rx ( Optionally use stock one)

Should be lots of fun making it all work, a challenge for sure, lots of folks here to help you get going.

Thats a huge help. I was planning on getting a DX7 anyway cause I can always reuse it when I think i'm ready for a trex600 :twisted: . I may have to send you a PM down the road.
Thanks again. :D

If both are Castle, you don't need to disconnect one BEC, the Castle ones will run together. Check their site.

Realise that to initialize the tail esc you will have to put the gryo into rate mode and give full left stick to give low throttle signal to tail ESC.

The one advantage to the 3/4 in 1s is that the tail ESC will arm at low main throttle.

Wow, Carlo you are a tremendous help. Thank again!

I was researching this a bit before and had a question. All the ESC's said no on reverse. Since the tail does not reverse pitch, the motor has to reverse direction. Will these ESC’s let it reverse direction?

Actually, as I am writing this, do I have a misconception? Does the tail motor ever reverse direction, or does it just stop turning all together to let the torque of the main motor bring it back? I know it does this to an extent but I am / was unsure if that is how it worked all the time.

Carlo, thanks for all your help on these forums, you among other people have helped me a lot. Thanks!

The latter, Slick. No reverse!

Excellent, thanks for the help Rebuild. I can't believe I never actually understood that up to this point.

Thanks,

Even if the motor direction is reversed, the tail will still work as normal, albeit much less effectively.

Huh?
