I have had the SS5800 for nearly a year now (wow!), and it is
still working like when I first got it. Racing rules still don't allow
them in our local racing, but some other clubs will let them run
at club racedays. It is definitely a mod motor citizen.
Brushless have no moving parts that can wear out other
than the 2 shaft bearings... which I haven't even bothered
oiling so far. (Have resisted all temptation to open the thing.)
Mine has seen at least 10-15 hrs usage (200 packs?) all of it in
4WD touring car. As its not a raceday, the Novak gets used
*continuously*, often back-to-back pack swaps without
letting the tyres cool down.
Its also been asked to do odd things... like carry an onboard cam
(ie 2kg car) and has been to the velodrome where it clocked
74km/h and held that speed for 4+ mins. Again it was running
in back-to-back races, stopping only for pack swaps.
I have tried running overgeared to buggery, the ESC has gotten
very hot but it has never shutdown on me. (Yes it was a test.)
Novak also runs more efficient than brushed. The velodrome run
saw many dumping at the 3:30-4:00 mark, but the BL ran 4:30
and I don't even have 'good' batts.
On our local track, the SS5800 can keep up with the mod boys
at the infield but loses a few lengths on the straight. The mod
fellas run 8-9t; BL has superior torque. At this level, driving skill
is more important than equipment ie you can buy equipment.
Just because you have a BL don't mean you know how to drive.
If you are a newbie to racing, it is unlikely that a responsible
club will allow you to race in mod regardless of what car you have.
If you don't know how to drive you will cause too much trouble
to a mod race.
I would suggest starting in the stock or novice classes; it is a
good idea to use what motor they run there. Motor/ESC is only
overall a cheap part of racing.
