tail bounce

[stevo]

hi guys quick question just installed a spartan on my 450 v2
took her out for first flight to check the gain, holds awsome
now when i give her elavater forwards or backwards the tail bounces i have tried the gain with no luck, before i fitted the gyro all was fine, very smooth
any ideas

try more speed on the motor pal or gripps to tight

[Ade_Law]

is this a vertical or horizontal bounce?

your description suggests its vertical as you mention it does it using elevator. If so its not the gyro, your dampers are foobared

if its a horizontal bounce after giving rudder input and letting go quickly try dropping the gain a little, if the response then gets soggy turn the gain back up and drop the deceleration in the gyro a little.

nope brand new dmapers trueblood only fitted 2 flights before new gyro no play, tried head speed no joy blade grips are same as before not to tight, and it is a vertical bounce, its really baffeling me lol

Have you fitted aftermarket light 3D paddels?

[stevo]

no everything is stock and before i fitted the new gyro the heli was perfect, now the tail holds better than before but i now have this vertical bounce when inputting elivator

[ivor-bigen]

i have herd if the weight of the paddeis is to light it can cause this.
but if there stock i do not know of another reason sorry.
Hopefully someone else can shed some light on it for you.

Hi Stevo

it is a vertical bounce

You can eliminate the Gyro from your list then.

Its most likely a problem relating to the following dampners/tight ball links/elevator function/loose boom/Stays/Sticking flybar/binding

ok guys thanks will strip the head and rebuild, thanks for all your help

your dampers are too hard for the current setup. i'd guess a low HS coupled with hard damping=this.

cheers
