Well, I bit the bullet and ordered the Mato 3:1 gearboxes for my HL Panther plus two recoil units in case I screw up while attempting YHRs excellent hL recoil mod (IMO you can't give enough credit to the ingenious innovation of YHR, kudos to you once again sir) Hopefully my mechanical chops will be up to the task of making this Panther a real IR battle contender.

Pics to follow once I get the bits together.

Cheers
