Gaui and FeiYu Tech

[rwilabee]

Does anyone know if the Gaui ESC's and motors are compatible with the FeiYu Tech FY-91Q.

Thanks
Rich

Yup, should work fine.

I don't know if you already have the fy91q, but if you don't,,, don't!

Take it from somebody who bought one.

If you do already have it, just fly the controller, not the nav., wait until they release the new firmware, if they ever do.

Last I heard they were going to come out with the fy99q and no word about whether the new software would even work with the fy91q.

My experience has been that the controller will fly ok with the Gaui electronics, but the nav never really worked.

 

[rwilabee]

No I don't have it nor am I planning to get one. A friend of mine bought one used and has a Gaui. He wants my help to change the Gaui controller to it. I just wanted to make sure they were compatible before I took a look at it.

Good,,, you had me scared for awhile!

Here's the deal,,,
As a controller it works just fine, not the best of barometers, but works semi-ok in the wind, deffinately a lot better than the gu344.
You'll want a seperate bec to supply power to the unit, don't use the esc's bec. It's very sensative to electronic noise from the ecc bec's.
It's a soft mount to the frame, the stock foam squares are about 3/8th's square and 3/16th's thick, spongy feel, mounted on all 4 corners.

There's 3 potts on the top to adjust roll, pitch and yaw gains. Between 11 to 1 o'clock is normal.
Arrow on top to point forward. Needs to be mounted dead center on cg.

Here's the manual, they actually did a very good job with that, at least.

Good luck, buddy.

Oh that is interesting they don't use the firmer mounting like my WKM and Naza. Good idea on the seperate BEC and thanks for a copy of the manual.

I was looking thru the manual and I don't see a place to connect the external BEC. Would you connect it to where you would have ESC5 or ESC6.

No, it has to be esc 1, only. Remove the red and brown wires from esc 1 and plug in the + and - from the bec in their place, leaving the signal wire from the esc in place.

All red ecs wires need to be removed. Just heat shrink over them.

I'm running my 330xs motors and esc's on my fw450 frame just fine with 9 inch props.

Great thanks for the great info.

I was just thinking. Maybe I could use a Y adaptor and cut the red lead on the side that the ESC plugs in to. That way I won't cut the ESC's wires to connect to the BEC in case I need to test it sometime.

Don't do that. Just use a pin to lift up the tab on the connector housings and pull the connector out. Don't need to lift the securing tab much to do this. Just remember to push it back down when you install the pin connector again so it holds.
Make sure you 'see' how the pin came out and push the replacement from the bec in the same way. It' a square sided pin and only one side has the relief for the securing tab.
Then heat shrink over the removed connector to pervent grounding out. Leave an over lap off the end of the pin, about 3/16th's or so and pinch it while it's hot to seal the heat shrink.
If you need to check thing over and reinstall again, the heat shrink pulls off.
Remember, you need to remove all red wires from all esc's anyway.
If you have a spare cable somewhere, just try it out once and you will see how easy it is.

Which brings to mind, the first thing I would do is to program the esc's before installing the bec, one at a time thru the throttle port of the reciever.
The Gaui ecs programming chart is on line with Gaui, if your friend doesn't have the instructions that came with the esc's. Unplug all the motors but one so you only have to hear one motor beeping, program each esc and then do the pin change out for #1 esc when done. Battery type needs to be nicd, motor timing medium, and soft cutoff. Remember to exit the programming at the end to save the changes made.

Make sure that you follow the motor rotation for the fy91q in the directions.

You'll need to go over every aspect of the aircraft before flying anyway, don't assume that just because it was flying with a gu344 before that everything was set correctly, so do a good job of it before flying. Easy enough to do and you'll come off looking like a champ.

Oh, and make damn sure you remove all props, first thing!!! Gives you a chance to double check their balance before re-installing. The fy91q only needs the throttle to be advanced to run, no arming like DJI.

Might be a good idea to print out this page and take it along with you to refer back to.

I see what you are saying. Remove the black and red from the ESC and then remove the pins from the BEC and then put them into the ESC connector as the pins should be compatible with the plug, is that correct?

Thanks for the tip on programming the Gaui ESC's. To bad I can't use Fun Fly ESC card to do the programming.

Thanks

Yep, that's it.
Programming just using the beep code is easy, really. Might take a few times the first time to understand the beeb sequence, but one you do I guarantee you will never buy another program card again.
Good luck, my friend!

If you want, I can pm you my phone number in case you get stuck.

 

[rwilabee]

Thanks that would be great. By the way shall we leave the stock voltage on the BEC or reprogram to a higher voltage like 6 volts.
