Leopard 2 board help

[GullibleFool]

Hello guys,

Looking for advice for upgrading my leopard electronics.

Currently running a HL 7.1 board. Tank has gun recoil, flash, smoke using servo elevation and recoil.
Have upgraded all the other internals to better quality stuff, so speakers, turret rotation motor, gearboxes are steel, motors are upgraded too. Added a roof warning light and rotating commander periscope.
I even wired in indicators, brake lights, and moved the rear lights to the correct place instead of the ones the HL Leopard comes with.

I want to add gun stabilisation and ideally have better sound quality than the HL board gives. I'm a bit lost looking at options, currently leaning in favour of a clark board but would appreciate any advice people have here.

As long as whatever board I put in can do good quality sounds and support servo recoil, elevation, and 2 plane gun stabiliser I will be happy.
Bonus points if it will do the engine deck gun elevation and let me do indicators seperately. Currently the 7.1 just turns them on whenever I turn the tank.
