[MOD] Dinotrack from 42065

[jam8280]

The only thing worse than a hungry meat-eating dinosaur on your tail is one with a tank! (Well, getting caught is pretty bad, too.)

Battery: 7.4V PF LiPo rechargeable in place (was AA box)
RC receiver/controller : SBrick/custom joystick on Android phone (was PF with bang-bang handset)
Motors: L front and rear (were Ms)
Drive train: Direct drive (no change)
Steering: Differential power to the tracks (no change)
Tracks: Lugs every link for traction (new)
Overall dimensions: 206x170x146 mm (LxWxH)
Mass: 546 g (down from 599 g)
Installed power: 4.3 W (was 1.5)

Power to mass ratio: 7.9 W/kg (was 2.5)

Stalled torque: 0.52 N m (was 0.18)

The biggest and most important advance over 42065 was in outdoor play value -- by far my best yet in any MOC or MOD. The biggest contributors there were the L motors and the red rubber track lugs. Dinotrack performance was generally traction-limited without the lugs.
