Default My Jeti to Spektrum Bridge build and a question

Here is a picture of my Jeto to Spektrum bridge. it was fun building it. Went to a place called Skycraft in Orlando that sells military electronics. That's how i got the case and switches.

I have a R3 receiver, PPM positive to the Orange DSMX transmitter. Have a LIFE battery sealed in the case and can charge or operate the bridge box.

I tried my Blade 180 but it seems very very sensitive despite DR and Expo settings and the tail doesnt seem locked in and twitches so often.

I dont know what to look at as the Gyro doesn't seem t make much difference. Any suggestions will be appreciated. If i dont fix it I will just sell everything.

The standard servo pulse width range for Spektrum (1.1ms to 1.9ms) is much lower than for Jeti (1.0ms to 2.0ms). Reduce your travel in the tx to about 80% and you should find the servo response is similar.

Default Thank you.

Thank you. Do I adjust the pulse width in Device Explorer? Where/how do I do that? Thanks.

You can reduce the servo travels a number of ways:
- adjust the function curves
- reduce the dual rate values

Regarding your twitching: try changing the receiver output period from Device Explorer. Start with "Auto" but if that doesn't improve things, try 20 ms, but also try higher values (eg 25ms) and lower values (eg 17ms).

Servo center is also not the same:

Default Still having issues with bridge box

I am having issues with the bridge box. No matter what I try it seems like the Blade 180cfx is .5 to 1 second behind the movements I input. The helicopter is al over the place.

I have set the output period to 7ms all the way to 20 ms. Any help is appreciated.

A nice video made by Esprit on Jeti to Spektrum bridge:
