Bls251 brushless tail servo

Just thought I would pass on some info regarding the use of BMS251 Futaba Brushless servo, when used with a Spartan DS760 gyro.

I bought this new servo, when replacing a JR 8900. When turning on the radio gear, the new BLS251 did not respond at all. Initially I felt sure this had to be a faulty servo from new, because there wasn't even a twitter or hold in the servo.

I was about to take the servo back as faulty, I thought I might as well check if Spartan had done any updates for the gyro. I found that they had a new version of the firmware and specifically, they stated that is now allows for these Brushless servo.

So I connected to the gyro and updated it off the internet. I then interfaced with the gyro editor software, to find that the BLS251 servo was now listed in the servo choices.

I simply selected that servo specifically from the list. Saved to gyro and restarted the spartan, to find the servo came to life.

So if your BLS251 is lifless when trying to set it up, ensure you get the latest gyro firmware and select that servo, using their editor software.

And just a comment on the flying side of it.. I was only getting a gain of 35% when used with the JR8900. I wound the gain up to 55% and no sign of wagging..So for some reason, the setting up now allows for more flexibility maybe.

2.4gig in a couple of models

Today I managed to get out and test my new 2.4gig receivers. I was a bit worried as I had some issues with the new G3 when it came out. I reverted back to 1024 pcm wth no further issues. So now this is another new technology.
But it went really well. Gyro gains needed adjusting, maybe to do the 2048 speed.?
A couple of pics from my gallery showing how I fitted the receivers and where I placed the two aerials. The instructions said to keep them at least 1/2 inch from carbon, away from electrical stuff if possible, while keeping the aerials at approx 90 degrees to each other.
With the use of the coaxial bit of the aerials, this was very easy.

14mz goes 2.4gig

You can now update your 14MZ transmitter so that it becomes a 2.4gig set.
It's real simple. Download the latest software and update your transmitter for free.

Then go buy the TM14 module and buy either the 14 channel or 8 channel Futaba receiver that is compatable. It not only turns it to 2.4 gig so that you can match up receiver to tranny, but the speed is in line with the G3 system, being 2048!!.
Here is a shot of mine with the 2.4 onscreen. You can see the new short aerial too.

Futaba 6ex 2.4 problems
Astra Astra's icon.
 2008-02-03 11:57:57
I have a T-REX 450X with XL upgrades, the problem i,m having is, i turn my tx on connect the heli battery and wait for the ESC to go through its course, i then push the throttle stick and let the rotor spin just to the point of lift off and when i throttle down the blades are still at the same speed even thou the stick is all the way down but if i throttle up still with the blades spinning as soon as i push the stick the throttle snatches and is controllable and i can throttle down as normal.
All the controls function as normal on the range / pre checks, any ideas please.

Has anyone had any experience of this Tx, it appears relatively new, and was wondering would this be a good place to start?
Or would i be better going for the spektrum Tx?

Futaba 146 receiver
Sbrown5925 Sbrown5925's icon.
 2007-07-13 20:56:49
I was told that most pilots with the trex 450 use the 146pcm receiver, if they have futaba as a transmitter.
I have a new trex450, and all was looking fine. Today I flew the model over the back of my garden and out of a field at the rear.
I reckon it only went 50meters, and when I banked it round to bring it back, it did not respond!

I raised my tranny and ran down the garden, at which point I got it back, turned it and flew it back no probs.
My concern is just what the range is supposed to be on that receiver as I was told it was reduced. I was however told that the model would be too small to fly when it is on the limits of range.

I wonder if there are issues with interference with this model, relative to the motor, or speed controller?
is there a bunch of "tweaks" regarding mounting the aerial or others to improve this?

Any help would be good.
