Reinforced standard Tamiya gearboxes ( drive cogs bushed out to remove excess play on shafts ). engineering done by Nigel I hasten to add

Improved Shumo torsion bars fitted to last 6 whee l stations on both sides for softer ride.
Gear box output shaft supports ( bushing type ) fitted externally to reduce strain on gear train.
Shumo rear idler fitted to improve track tension and reduce rear hull flex.
Bearings in all 16 road wheels.
Custom built battery, electronics and speaker holder.
MG ball removed and filled in.
The upper hull has had HL rotation added with faster motor to improve turret rotation speed. Scratch built rear 3 piece engine access hatch and vents. Added fuel vent lines.
Turret now has HL Stug elevation unit fitted ( needs a little more work to lock things down things a tad as the barrel is still a bit wobbly )
IR emitter fitted to front face on turret
Range finders added to turret sides.
Now for the good bit a couple of pictures
