Tail bounce on 500 EFL Pro

[Delarado]

guys,

Get a tail bounce on my 500EFL pro on stops from piro'ing.

Its much, much worse when going CCW, its probably about 1/5 of a turn back when you stop!

Reducing tail deceleration just makes the bounce slower and more lazy. Reducing tail stop gain CCW doesnt seem to have much of an effect.

What other parameters can I play with?

this is exactly the same as the DS760/Quark, you will need to adjust the decel until the bounce is gone then you up the stop gain to get the crispness back. you appear to have turned the gain down which will have the wrong effect.

cheers

I turned the decel down to 10% i think. The bounce was still there, it was just slower.

Ill try again anyway to confirm

Iv just had my first 4 flights and have the same problem, did you get yours sorted out ?

As Raptorheli said,
Reduce your deceleration gain right down and increase your stop gains up.
On all the machines i have installed a vortex,i found the best way was to first adjust my tail control rod (neutral position of slider) so an equal amount of bounce is present on either side.
Then reduce decel bounce.As this value decreses you will see that the bounce becomes soggy but still present.By increasing the stop gains this will remove this soggy bounce and allow the tail to stop sharply.On a couple of the setups i have done i found that i could remove the bounce by 99% but just couldnt get rid of the last tiny bit of bounce.In this instance i found that by reducing my main tail gain by 1 or 2 points this would then clean them up perfectly.

As a guide here are my settings for my trex 700n, to give you an idea.

cw servo end point 106
ccw servo end point 140
main tail gain 26%
acceleration 120
deceleration 0
cw stop gain 170
ccw stop gain 145



hope this helps

Excellent, thank you, will give this a go weekend. Thanks

Andys guide has sorted my tail wag and it now feels awesome to fly, if anyone else has a tail bounce just use the settings as per above and adjust from there.

Remember to adjust your tail rod to equal the bounce in both directions and reset the tail servo end points each time you adjust. I think I had to lengthen my tail rod by 3 turns to get it right, then adjusted the parameters like above and now it feels great.
