"TIGER I: (built plus feedback)
No Major Issues -
1) The Track Tensioner could be better - 2) Keep an eye on you track through out the day. The tracks can jump on the idler wheel - 3) Fabricate your own Tension system, or purchase an aftermarket tensioner (Daryl Tuners upgrade).
1) Main Gun Barrel Seam - 2) May cause recoil issues - 3) Careful sanding, filling, and painting of the seam,or replace with metal barrel.
* 1) Gear Box Brace - 2) Helps reduce gearbox and chassis flex. Metal Tracks cause more stress - 3) Fabricate your own or purchase after market (pcomm1)
