Futaba 6EXH vs. one with CCPM?

[Phyroinstinct]

Hell,


Hoping to seek out some answers, tried the searching, got lots of info but non that I felt quite answered my questions.


I was looking at a futaba 6EXH with Rx R146iP PCM mini 40Mhz channel.

Or like a OPTIC 6

As I understand it either of these controllers dont have CCPM?

Im pretty darn new to this sport/Addiciton. And IM hooked.


I made a mistake about the chopper I bought But I want to correct that slowy. Im looking at a new Tx Rx.

I got a walkera 36B w/ 240 Gyro metal tail and head some upgraded servos.

Im focused to mabey doing some flipps way down the road, but nothing byond just fly around and up left right spins that type of amusment is enough for me. For now.

My walkera controller has CCPM I know what it stands for but dont understand it totoaly. Why itsa better or worse?

Would one of these controllers benifiet me? Lacking the function of CCPM?


Im hoping some of the more expericned guys/ladies can help me out.


I put this in futaba section cuz thats primarily what im looking at. So I figured this beylonged hear.


Ow, its 40Mhz, is that much better/wose then 72,

Thanks for any info.

I don’t know who told you that because they are flat out wrong. I am flying the 6EXH with my Swifh and T-Rex both CCPM mixing. Here is the manual on line I suggest giving it a read. Page 18 shows CCPM programming. http://www.futaba-rc.com/manuals/6exh-manual.pdf

Ahh, I do see what your talking about, the distributer I was speaking to was very incorrect.
Would you know if its neccessary to use digital servos? I do not think mine are digital.


Thanks for the corrected input!

I have not flown the Walkera so I can’t comment, but on my T-Rex I did not use digital but I am on my Swift. Digitals will give you the edge with better centering ability. Just try and use servos with ball bearings for sure.

[broke-again]

Phyroinstinct, in response to your Q. I recently purchased the Futaba 6EXH and to honest its a pretty good system & easy to set up. To date the only down side is the fact that it does not offer a sub-trim option, which is pretty handy when your trying to get your servos set up to 90 deg. To overcome this, i set the servo's up as best i could and to be as accurate as possible, i used a swash plate levelling tool. All in all it's a decent system. I dont fly the walkera anymore, though i started out with 2 22e's before deciding to get my self the HDX450se. I use HS56's on the swash and a digital on the tail..with gy401..so far so good.

PCM will save you problems associatted with interference etc.

Good luck

If you are making a step up to a new Tx don't get one without digital sub-trim adjustments or you will regret it.

IMO, of the two you mention I think the Optic6 would be a better choice but you will need a HiTec PCM Rx to go with it as you cannot mix Tx/Rx brands when using PCM.

Take a look at this comparison: http://www.hitecrcd.com/Radios/Optic%206%20comparison%20chart.htm

If you want to stick to Futaba then stretch another $50 for the the Futaba 7CHP. Down the road you won't notice the $50 but you will really appreciate the better Tx. You could also consider the JR6201 or 7303.

Good luck.

I am using two of the 6EXH radios and have never had any issues with them. Sure they don't have Sub trim but all that means to me is when setting something up, it requires a little more time to get it mechanically set up. But in reality-- if you have to spend extra time setting it up right. It sure makes you understand the mechanics better. Anyone can press a button, the precision mechanic can do it without buttons.

Of course my real recommendation against a 6EXH would be a Spectrum DX6 for sure. Secure, glitch/lockout/shootdown free operation and no frequency management issues. :D

And don't forget the colossal 3-pont pitch and throttle curves and what no sub-trim? :wink:

[kgfly]

3-point curves
=========
Yes the DX6 has 3-point curves, and works great. Most example curves I see are very close to 2-part linear. For example:

Normal - P:40-50-100, T:0-85-100
IdleUp - P:0-50-100, T:100-85-100

IMO 5-points adds a little more control at low pitch for Normal mode and nothing much in IdleUp. :)

sub-trim
======
The DX6 has digital sub-trims :D

[Phyroinstinct]

I was looking at the DX6, but I cint find anything on its range.

Any ideas as a user?

[kgfly]

Do you mean the range of the radio link ?

Claimed is 800 to 1500ft, more than enough for a heli for sure. Actual measurements by users have exceeded 2500ft and one guy flew an RPV 14 miles away between mountain tops!

This is the most secure radio technology currently available and at a remarkably low price since at the moment it is packaged in an entry level 6-Ch Tx. Other mfrs are working on 2.4GHz spread spectrum solutions but so far none of the majors (JR, Futaba, Hitech) have announced release dates. A new vendor ExtremePower, has announced its own impressive sounding range of 2.4G Tx modules to suit JR9303, Futaba 9C and Hitech Optic/Eclipse Txs and the corresponding Rx. The specifications are even more impressive than those of Spektrum with the advantage that you can choose your prefered Tx and also they will support from 8 to 16 channels. They announced it for release in October but who knows if they will meet that target ? If the product proves to be as good as it sounds it will be a revolution. For now, the Spektrum DX6 is proven and offers an excellent solution for small helis at a bargain price. If you outgrow the features of the DX6 Tx there is a simple upgrade path to convert a JR6102 with the RF module from the DX6.

[Phyroinstinct]

That was the answer I was looking for. The distance the unit can fly away. 800Ft is more then Ill ever use with this heli. DX6 Is now a viale option.

Thanks for th input :)

[Phyroinstinct]

I ended up going spectra DX6. With there 4 new mini micro servos.

I have only taken the time to set up the servos and the controller a little bit in normal. But Upgrading the electronics, it is remarkable how much easy/better this bird flies compared to before. And the digital trim, I love it.


I wanted to thank everyone for there input. Helped me make a discition on the correct controller for me.


Thank you everyone!!

Phyro,

Welcome to the 2.4 revolution :D

Just be aware that the S75 servos that come with the DX6 are not recommended for a TRex. They are typically too weak, do not centre reliably enough and wear quickly. Ideally upgrade to 3 x HS-65MG for the swash at least.

I have a question about the 6EXHP. I am currently using one on my walkera 36 and t-rex 450se. My quesion is, is it possible to dial in expo on the cyclic whilst using the ccpm swash plate option. If you add expo in the normal way, surely you are only adding it to ch1 and ch4 which are only 2 of the 3 ccpm servos.

I hope I explained this ok,

Jim you sure can. See page 12 of the manual. http://www.futaba-rc.com/manuals/6exh-manual.pdf
Dual Rates and Expo setting are in the same programming area. They control your stick position (movements) and the swash AFR output (if you are in CCPM mode) is taken care of by the radio computer.

Ok thanks. I know how to adjust the expo but I just didn't know in ccpm if it would just add expo to two of the servos or actually to the cyclic.

[AV8TOR]

It will add it to all of the servos that are moving for that mode/channel number programmed for expo.
