Just got the T10C

[Rotorhead]

Ok, I will say that IMO nothing feels cheap on this transmitter, it may look that way in photos, but it feels very solid.

What matters is performance though, and I will be seeing what its like over the next few weeks.

Previously I was using a FF8 for years, and with this there was a noticable difference on the bench with the latency, its clearly lower.

I can live with the 2.4 antenna being where it is, and its nice that I will be able to stick the 35MHz module in and use the 35meg antenna with other models.

Funny that there are negative comments here just based on cosmetics.

Personally I dont care what a radio looks like, but how it performs, and so far I am not disapointed.

Infact just this minute, playing about with it, I have found another feature that is brillient, in the throttle and pitch curves you can alter the horizontal positions of the points, if you want all the points apart from the top and bottom all in the top half, you can, or in the bottom half, you can, they are not fixed at all.

I would debate that 'feel' is a cosmetic attribute, but hey, I'm sure it works great, and each to their own. I'm sure you'll have many years of excellent service from it.

i know my FF7 has a plastic feel to it lol ... but i had a play with the 10C at the shop and prefer the 12 over it ... but am rough as hell with Tx's so will stick with this for a while heh e

Well I think it feels very good, it is solid, has nice balance, the springs are not too slack or tight, the switches are ok, the screen is clear, ok the jog dial could be better, but it beats my FF8 hands down.

can someone take one apart and look how the total digital bit works? i mean, how do they do away with pots?

He's had it 2 minutes and you want him to take it to bits lol .....I think alot of people like stuff to look nice and have an expensive feel to it .... This is Y i said that it feels cheap lol .. Futaba could do with taking a leaf out of JR and make the radios a little more robust lol ... Personally I have held the 12 and the 10 and the 10 does not even come close to the 12 ... But at the end of the day its each to there own ... I might forgo a new heli and get a new Tx .. Hmm 12 me thinks lol .......As long as ya Happy Leon thats all that matters and am sure it will be alot nicer than ya FF8

Actually I have taken the back off to take the ratchet off.

I dont know where this idea of them not using pots has come from, they would have to, and even if they used something like hall sensors, they would still initially create an analogue signal.

Without really taking the thing apart its hard to see, but it looks like pots.

I think that what futaba mean when they it starts digital and then stays digital is they mean that the analogue to digital conversion is right at the pots instead of later, and its not converted back at any point for any reason.

It has to have some analogue stage initially, otherwise you would have a hard time getting any proportional feel from it, without some analogue stage its going to feel like its only got two states, on and off, clearly thats a bad idea.

Hi Rotorhead glad to hear you say the set ballances properly.
This is the one thing that realy annoys me with the DX7 spectrum set & the new jr 9x 2.4 the ballance on both of those sets is awfull & using a geforce hangar isnt al its cracked up to be I can tell you
This is dire imho on the JR 9x 2.4 as your spending upwards of £350 on a tx that doesnt hang well on a neck strap

I've had many sets in my 30 years in this hobby & Futaba ones have been as good as any of them it realy is down to personal preference at the end of the day. "Plasticy cheap looks" lol, get real guys it's hardly in the esky league now is it

Er, no sorry that's totally wrong. Digital doesn't mean it has two states (you're thinking of binary) -- digital means the value is represented as a series of binary digits, eg. 10 bits will represent 1024 states, and not only available as an analogue electrical signal. Otherwise a digital watch would only have two times

They could easily be digital at the gimbal level, the reason it isn't is probably mostly because of cost, greater reliability (and a much greater resolution to work from), partly I imagine tradition and just good business sense.

Or something

Er no, thats totally not what I meant, I meant it would be digital as in old arcade joysticks, ie left, centre or right.

It has to have some analogue stage initially, otherwise you would have a hard time getting any proportional feel from it, without some analogue stage its going to feel like its only got two states, on and off, clearly thats a bad idea.

Infact in that part you quoted, I dont see any instances of the word digital

Old joystics for things like the amiga 500 (ah memories) or arcade machines where either analogue or digitals, and the digitals had microswitches in them, so it was either all or nothing..... on or off.

You have no need to be explaining electonics and data principles to me

It couldnt easily be digital at the gimbals, you still have an arc of data points to sweep through with the stick, you still have to encode them, infact it would be very difficult to have it digital right from in the sensor right from the get go with enough resolution and be small enough, the sensor would have to have an ADC built into it to do that, even then the raw data its measuring is still going to be analogue.

Example, I have here a TM cougar joystick, its advertised as a digital joystick, but it still uses pots (or hall sensors if I upgrade it) to measure the position of the stick, so its still analogue until that signal gets to the ADC.

There is still an analogue stage, the question is how far along is it before it gets converted to digital, I'm guessing its the first thing that happens before any other processing.

Whats likely is that the sensor is just a pot, then the first thing that that feeds into is some ADCs, where they physically are is not important, they could be on the PCB or right on top of the sensor, I would guess on the PCB, but either way its the same thing, geographical location isnt important, whats important is if there is any processing done before conversion or not, and futaba says there is not.

Well it feels balanced for me, so thats just my opinion there, others may disagree.

[DemonJim]

Sorry Rotorhead, my point was it doesn't need to have an analogue potentiometer at some point, ie. one that uses variable resistance, which is what I thought you were implying. I understand now you clearly meant analogue as in the stick has a range of positions, but of course it has to be like that, that's not the point of the discussion (hence my thinking you meant it has to be an analog electrical signal at some point).

I was saying in response to that it could all be digital from a stick-position perspective (and have no danger of a getting jitter due to a dirty pot) which I thought was the point of the discussion. For example using small lasers viewing a spinning disc full of tiny holes like how the roller on a ball-mouse works - at no point is a variable resistor converted into digital encoding from the users movement (the ADC), it just has to sample often enough to handle very quick movements. Saying that even this system has an ADC at some level is just pedantic, as the point is this isn't in directly converting the motion of the sticks into digital.

As you have explained it would be difficult to get good enough resolution using this sort of system, hence why I said it'd be expensive and not worth the development costs when analog pots work fine. Sorry for the confusion, although I'm sure few are bothering to read all this anyway, they just want their TX to work properly

[Rotorhead]

Fair enough, I suppose thats all everyone needs to really know, does it work or not, and so far on the bench it seems fine, I wanted to go out and have a flight with it today, but.... weather

Oh well maybe tomorrow

[Mark J]

Will have to let us know if you do go test it tomorrow as if can, might pop up and take a peek etc

baa weather ... ya a fair weather flier now Leon lol ... I was up there flying lol
