I just got a T28 Trojan Durafly PNP and a Turnigy 9x Rx mode2...from HK (usa).
I have a few questions as I test each servo connection . Ailerons work right (ch1) , Elevator (ch2) is reversed which isnt an issue I guess since I can do that after I get used to the turnigy9x. Ch3 for power is working.
Issue is CH4 rudder , which has 4 splits. I checked each :
1st for LED, 2nd for LED, 3rd made the rudder servo quiver a bit, 4th connection made the Nose servo inside the bay quiver a bit ( heard it).
Rudder servo isn't moving via Receiver stick.
The CH5 ( 3 servo splits), one for each 3 of the wheels for gear/retract is not yet configured in radio. Thus wheels are inside the bay.
1) Rudder not responding via radio ...is it because the gear is not "down"? Will rudder work only with nose gear down?
If so, it seems to be standard channel 1 through 4...with channel 5 being used for the retracts.
Are you also using the 9X transmitter?
If it is, more than likely the transmitter needs to be programmed to accommodate all of the trim settings for rudder, aileron and elevator controls.......you'll need to study the TX manual in order to decide the best channel and rates for the retracts and flaps.....IMO, way to many bells and whistles for a first timer low wing pilot with little TX programming experince....I'd suggest getting together with an experinced pilot at a club or your LHS and take notes.
I was able to configure the CH5 gears yeaahh ....Thx to Nigel's docs.
Still have issue with CH4 - rudder.
CH4 rudder , which has 4 splits. I checked each :
1st for LED 2 wires, 2nd for LED 2 wires, 3rd has 3 wires ...made the rudder servo quiver a bit, 4th connection has 3 wires...made the Nose servo inside the bay quiver a bit ( heard it).
Rudder servo isn't moving via Receiver stick.
I checked "display" in Tx menu , throws are normal (ends) , EPA is at default, Also tried reversals . Even with the gears down ...Rudder & nose wheel aint working . When I move the left stick left and right there is no noise, quiver nothing....But LEDs are working(CH4 ).
Since there is quiver/movement when I connect the 2 servo leads (with correct colors matching) , I think its a setup in TX or something missing in RX ( physical wired connection for signal cable missing).
Why are the LED's on channel 4? They have nothing to do with the rudder. Normally, lights would be on an aux channel or on channel 6. If the rudder has one and only one servo(like it should) and the servo rods link to the steerable nose gear, there should only be one plug for channel 4. No "Y" harness for the rudder as there should be nothing to "Y"
Seems like you're confusing the LED's with channel 4. Unplug the lights to channel 4. Follow the wire from the servo that controls the rudder and plug it in alone. Then worry about plugging the lights into channel 6.
LED's on models like these are usually just able to plug into any open rx plug. I didn't know it before, but learned you can 'Y' them into any other channel you care to, rudder, elevator, etc. They are just getting power. Personally, if I had to do this (I have in my FMS P-51) I would put it on a channel using only one servo otherwise. Don't know if it really matters, but I figure it's better to not put too many things into one channel of the rx.
No disrespect to any of the comments that your getting here 747 but there is a big thread on this plane with the same radio you have over on rcgroups,just thought someone over there might be able to help you out more,or had the same problem as you,if so you will find the answer if not i bet a google search will find one.
Just a thought mate and good luck with the maiden.
Glad it's all sorted now 747 and as far as asking HK for another RX might be worth a try,see what there CS says as they might be able to sort it out,you could always go over to the T28 page on the HK website and ask in there discussion thread tab near the price,someone on there might be able to help as well,just to make sure you good to go.
+1 on what Hawk said about having someone stand next to you to help out with the trim.
2 pending issues:
Lead from rudder servo is covered with paint....every now and then rudder doesnt work, works after wriggling lead or connecting again.....unfortunately to replace I have to loosen servo, rods which hate now.
Other is epa for pit trim wheel ain't responding, plus I just can't get to highlight the up flap....only the down for epa gets highlighted. Even tried rotating the wheel of pit trim when that is highlighted in EPA mode, didnt change the focus.....so tried changing down flap to 10%...but no diff in throws.
