EzUHF woes

[Dusty]

just installed an 8ch lite RX into my skywalker. as usual the ESC/throttle servo plug is in ch3 on the RX.

when I power up the ESC (with tx already on) the motor does it's usual ascending 3 beeps, but then it just beeps every 3 or 4 seconds. I first thought I might need to calibrate the throttle on the ESC, so I powered everything off and back on with the throttle stick all the way up... plug in the ESC and exactly the same happens, no indication that it's detected high throttle/calibration mode (it's a 60A plush).

So, back to turning it on "normally", that's with the throttle stick in the down position. it does the 3 ascending beeps, then the single beep every 3 or 4 seconds... I leave it like that and after about 20 seconds (i did absolutely nothing) I finally get the long beep from the motor. I try the throttle stick on the tx and nothing, but then after a delay of around 5 or 6 seconds, the motor spins up. when I put the stick down, it doesn't stop spinning until around 5 or 6 seconds later, but it's not always the same delay.

I plugged in the pan servo for my camera into the rudder channel. same thing, there's a massive delay but the servo movement is no where near "smooth" compared to when I first tested it.

has anyone heard of these issues and is anyone able to point me in the right direction please? thanks.

try a rebind

Not used EZUHF but usually the Tx needs to be in PPM mode to operate these modules!

Oh and you didn't sell your rangeLink did you?

[Dusty]

Hi BM, yes I sold it ages ago... I needed to raise some funds to buy an iPad for when I went to Afghanistan. I'm back now, with a hefty bonus, so thought I'd upgrade lol

Right, back on topic...

It turns out that I had the tx and rx on different frequency bands, one was on 433-435 and the other was on 430-450 (xtrm hopping). Put them both in 430-450 and all works perfectly. Even the Storm OSD is now running from PPM rather than having 4 servo wires plugged in. Techinically, because I'm not using RSSI yet (EzUHF rssi not compatible with Storm OSD) I could get away with using a 4ch receiver in this:

Ch1 - PPM (AIL, ELE, Display Mode, Flight Mode)
Ch2 - Pan Servo
Ch3 - Throttle
Ch4 - Rudder

Glad you got it working, EzUHF FTW!

how come throttle and rudder can't be on ch1 as well?

[Dusty]

Storm OSD only controls aileron and elevator when in Pilot Assist and RTH mode, it doesn't control rudder or throttle. They have to be directly connected to the rx.

[xxpitt]

how does it return to home without any throttle or do you set your rx to failsafe with %50 throttle and rth mode

[Dusty]

Exactly like that

Been messing with rssi on ez today corps , one cheap easy way to convert pwm to analog voltage is use a old tiny servo take to circuit  board out of it center pot  optionally test and replace with a resister shrink rap neat little converter , parkzone one one I used game me 0 to 3.5v
