Car got a brushless update (11,5T), beltdrive takes it well, not the tires..

Rebuilt these (leaking) shox as well.. the red Tamiya silicon o-rings work perfect as substitute. Try 27,5wt oil in front and rear.

Perfect weather for finishing the car.., green or black?
Running ultrasilent, hope to test it outdoor the next weeks.

Built the Saurus chassis from (almost) new parts. Some Platinum's for the rear fit perfect, for the front even the short ones seem too long for reduced ground clearance. Took some alloy dampers with modified pistons / Tamiya red silicon o rings and placed it in a position I found on the Kyosho boxar...

For comparism: rewound and soldered an old (burned) Tamiya Technigold (same wirediameter (.80)
and also 21 turns) and measured it with my two others: about 1.5K more revolutions under load and
slightly more max. output.

Some armatures I did years ago for some straightaway and racing. Soldered with hightemperature lead (300°C+). Balanced statically via razorblades, dynamical with a structure made from piano wire, bearings and a hand drill. Afterwards epoxied the winding and armed/trued the comm. To maximize the copp...

Belt module is GT2 (or 2GT, means 2mm per tooth). Calculated length 142mm (71tooth). Pinion
16tooth and maingear 50tooth (better take 48: only very small gap to the outdrives left). Smaller
pinion should be no problem, respectively with a slightly shorter belt.

Thanks! The motor direction remains "counter clock" due to the obsolete middle gear..

Works smooth and quiet:

After destroying several UM-1, I searched for a substitute and (hopefully) found it in parts from a 3D plotter store (for just a few cents)... pictures:

Hi there,
