I just wanted to thank you for your patience yesterday.
I read from #2 until my eyes were spinning. Then I gave up and went to
bed.
Started afresh today with an old notebook running Win XP.
Everything worked on the first attempt.
Thanks again
Chris

That's AWESOME! Glad you were to get everything programed into your radio. Thanks for the headsup on the file sizes. I just used what worked and never thought twice about it. Learned something new.

Wish I had known you were on Mars. I would have dropped in for
drink on my way to Saturn.
Thanks agin

Here is a quick video I made about setting up a hacked Flysky TX for a Traxxas Summit :

Question for you guys I just got a hacked gt3c and set up a winch to the d/r switch channel 4. I'm having trouble with a setting some where when I plug in the battery or turn the radio on the winch starts winding in any help would be great.

I believe failsafe is set on bind of the receiver, I have an issue on one truck right now where if I turn off the radio first it drives backwards slowly. I am thinking of rebinding to reset failsafes myself.

My issue with the radio right now is that trim has far far to little range. :/

How fast does it start winding?

Does it have the upgraded firmware? If so, what do you have that requires so much trim?

[losikid]

A couple GT3C's are in stock on my site....more on the way.

I figured out what my problem was I had two switches mapped to the same channel that the winch was on. Everything seems to be working perfectly now

Trying to set up the steering on a rather crappy p402, but irregardless. I measured the deflection of the steering servos on both my TRX-4 and this p402. They both have about 20mm center to center servo horns but the flysky from r99 to l99 has 2mm approx of end deflection and the TRX has 10mm approx. 1/4 of the throw seems really limited.

And yes, I have a radio with the 0.6.1 firmware. It's not that I need a load of trim, but when trying to get the geometry working acceptably on this the trim was almost useless. You kind of have to set everything perfect at the get go because there is no trim to smooth out issues, if it's half tooth off I end up using up all of the trim one direction to get it centered, I am not used to manhandling the trim quite so brutally to get things in line

Trim isn't supposed to be for major changes. It is intended to make very slight adjustments if your car is pulling slightly one way or another while driving down a straight line. You are supposed to make mechanical adjustments to fix major offsets. (Such as lengthening or shortening the drag link on solid axle vehicles)

Servo's have limited throw and using trim will reduce the amount of throw you have in one direction. This is why trim is limited to 10% of servo throw. It lets you adjust 0.1% of throw per click to let you fine tune center. Think about go fast cars. 0.1% is a lot when going 30+ MPH.

Also, trim is usually used for on-the-fly adjustments it moves the center allowing more travel in one direction or another. Sub-Trim (Long click on the Trim menu), is used to fix servo horn alignment issues. It moves an endpoint (which will cause the natural center to move as well). This allows adjusting the center but still have equidistant travel left and right. You could technically double dip and max out both trim types to get a big offset but this is a noob move.

I'm confused as to what you are trying todo? What are you controlling?

[KMS]

Do you repair them Losikid ? 1 binds to receiver then nothing other short range only . gt3c radios

You would set up your radio as a normal 3 position switch. The radio doesn't "know" it's a 3rd function. The heyok controller does.

So from reading that description, it sounds like HeyOK wants a momentary 3 position.

To get momentary 3 position control for firmware 0.4.1

Scroll to REV, press and hold enter,
Scroll to 3, press enter
Scroll to CH3, press enter (Or choose whatever channel you want to control)
Scroll to MOM, press and hold enter
press back/end afew times

That should do it.

[nedmo]

I have it working using both direction of SWI setting on ch3. But there isn't any specific sequence to light circuits activating. No where near as clearly defined as heyok instructions

[losikid]

That's because SWI is the wrong setting.

Reset your model (Scroll to NAME, press and hold enter)

Now,
Scroll to REV, Press and hold enter
Scroll to C, press enter
Scroll to OFF, press and hold enter.
Press back/end afew times.


Now follow the directions I posted above to setup a momentary 3 postion switch.

I made a video on how to set up 4WS (with Crab) and DIG (with reset button). Hope this helps someone:
