Two RX's will work, alas on the same six channels, so no joy.

Not sure on Telemetry, would suggest it was not an issue, due to the telemetry gear being coupled to one RX.

RE: The

Its unlikely returning the servos to factory defaults will solve any problems. Servos used in ganged applications must be match centered and provide equal degrees of rotation stop to stop. Best case...

RE: Hitec Digital Servo Programming

Howard,

I'll see what I can do with a step by step explanation, I'll have to get out the programmer and work through it taking notes...

RE: The

Paul

It’s very important to match the servos center and travel end-points in this circumstance. And yes opening the dead-band may calm things down a bit. I strongly suggest the use of an...

Not sure where you going with "The centers are so close on new, good quality servos" close to what one another, or? As I suggested previously there is KNOW magical center point, if the...

RE: Aurora 9 throttle servo??

Binding can occur at either travel stop peculiar to the linkage and or carburetor end point mechanical stops or; somewhere in the middle too. Simply make sure your not driving the servo past the...

RE: The

Does the jitter stop if you remove the control horn from the servo? Is the rudder hard link connected or cables?

RE: Aurora 9 throttle servo??

Make sure the servo is not binding at any point in the travel arc... Do you have an inline servo volt/amp meter such as Hangar 9 offers, this will indicate the current draw and voltage the servo is...

RE: Hitec Digital Servo Programming

I see questions with regard to centering the servos often, with regard to the servo horn. What are you referencing for centering the servo arm, the servo case, hinge line or? In any event this is a...

RE: Servo Programmer question

Daddy,

What’s your reasoning for centering the servo arm to be perpendicular to the case? In a perfect model where all things are equal this may make sense, but our model specific linkage...

RE: SYSSA 30CC GAS MADE IN USA

How about throttle trim or some TX function with regard to throttle and "engine kill function"?

Maybe something to do with choke, did you verify the linkage was actually rotating the choke...

RE: SYSSA 30CC GAS MADE IN USA

While a 100rpm reduction is likely all that, this is a new engine yet to be broken-in which is exhibiting teething pains. Thus my suggestion to drop 300rpm, this will create a baseline that the will...

RE: SYSSA 30CC GAS MADE IN USA

Rob,

Using the TACH to back off the high speed needle until you note a loss of at least 300rpm. The 1/4 turn is simply a suggestion. And remember when tuning; the low and high speed needle...

Jake,

I’m not aware of any examples per say, its just something that was realized with some RX’s with multiple ganged servos on a single RX channel. Some RX’s were at issue other like...

Don,

I here you but it works with Hitec gear and and most other RX's. So it may very well be a RX short-coming of sorts. That said Hitec does not claim it works with other gear, only theirs...

RE: Hitech/futaba wierd failure

Don,

It's no fault of the Hitec stuff and there is nothing Service can do to alleviate the problem... The RX in question is not likely 100% compatible with the Hitec synthesized TX module.

RE: Brendan, Mike, help with a HPP-21

Simply use sub-trim to center the servo to offset TX electro-mechanical anomalies. Sub-trims don't use up pulse-width like trims do.
