B17 Tubby Aura-5 With Diff. Spektrum

[NOV8R]

Urgent!

Finishing B17 Tubby build using the aura-5 with the B17 config. with Diff. Thrust.
I have the Aura-5 configured properly, but I have no info how to setup My Spektrum TX.

What airplane type or channel config's are required to properly setup tx to handle the odd 5 rx port assignments
in the order of Thr-L, Thr-R, Ail, Ele, Bomb.

Also, per instructions, all 4 of the red power leads from the esc's are connected to aura/rx.
I thought 3 of the 4 had to be disconnected or possible damage might occur.
If I would disconnect 3, will the one remaining esc have enough power from its
BEC to power the plane?

I am assuming you used the file available from the B-17 Tubby page in the store to configure the Aura5... https://store.flitetest.com/ft-tubby-b-17/?searchid=0&search_query=tubby

Your radio needs to be TAER, and the flight mode/dual rates is on channel 5. An additional channel for the bomb drop will be needed other than these channels in the transmitter.

The Aura 5 is TAER and the 5th channel is the second throttle for differential thrust.

If you want to use an additional channel for bomb drop with the Aura 5, you may need to use a PWM reciever that also has serial output in addition to at least 6 PWM ports. (fewer if it is an ELRS reciever)

Yes, using b17 file from their website.
Per video, they have you hook up aura ports as follows; tl, tr, ail, ele and bomb drop. No rudder us used. They say aux-2 is bomb drop.
I don't see how TAER would work!?

I finally got it working,
Yes, had to use the standard TAER setup in the radio.
Set a switch for GEAR = three Flight Modes
Set a Switch For Aux-2 = Bomb Bay
Set a Switch For Aux-1 = Turn on/off Throttle Differential

Did not disconnect any of the 4 RED wires from the ESC's

It looks like the original issue was in the Aura-5.
Went into Aura-Config and noticed they had satellite set as S-Bus vs. SRXL-2
Also had inputs Set to AETR vs. TAER
Once I corrected that, the aura saw the Serial Satellite.

Works great.
Thanks for your help!

Ok, I wasn't sure if they had a rudder in addition to differential thrust. That makes sense, because that would free up a port on the aura for the drop.

I would be hesitant using the red wire on all the ESCs at the same time. The voltage regulators can have issues when run in parallel. You should remove two altogether, and find a way to split the servo power between the remaining BECs. The other option would be to remove all 4 and use one high current BEC.

I received a email back from FT on the 4 power wires from the esc's.
They said i shouldn't be worried, that that was only an issue with older esc's.

I ran it with all 4 hooked up and it seemed fine.
