Hi there,

I build a leo 2a6 myself and it's a great monster.
You'll need verry few after market parts to make the leo a great runner.
Basically only the suspension arms, bearing set and idler adjusters are really needed. You can even dispute the suspension arms, but the originals broke on my one.
All the rest is just up to you.

The tracks are great so I wouldn't put down to much money on metal ones, and I don;t think the gun stabilization is worth the money. The Gun stabilization works with a delay and I found that more irritating than it was worth the investment.

What you should buy is a machine gun because that part is left out of the kit, and I would pig out on detail parts rather than barrels, sprockets and metal tracks.

Have fun with the build!

greetings,

Pim
