Is it me or is the El-Mod site the most confusing place on planet Earth?

I have a Heng Long Tiger 1. Full Metal options fitted eg tracks, gearboxes, suspension, hatches etc etc. It weighs a ton!

I am trying to figure out how much I need to spend to convert it to the ElMod system so that I get the sound, proportional speed and turret rotation, whilst keeping the airsoft gun, and if possible the smoke unit? I cannot figure out what I should be buying??

Just to complicate matters I would dearly love to get hold of the Creeping Death Tiger Turret so that I get an airsoft gun, plus laser with extended barrel and recoil.

On top of that I am looking at fitting some decent motors. Though only if they improve on the whitecaps that are currently installed.

I am happy to buy a new tx.

(I daren't mention that I am also an old fossil from the UK who works in IT, I still have trouble with a video remote??).

Can anyone list the parts I need, and the cost either direct from ElMod or the U.S. I would be very grateful.

Hoping there is someone out there willing to take pity on a befuddled Brit!

Cheers
