Questions:
01. Why is the TC2 faster in terms of acceleration, it just uses a 27T Arm?
Not to mention longer run time.
02. Why is the TC1 and the TC2 had the same top speed? The FLR and RZ has
more RPM I think.
03. Why is the TC3 the slowest among the 3? Should it be geared higher?
04. Will changing to Novak GTS/GTX/Rooster improve the speed
performance of the TC3 or just use a lighter body?
05. Will putting ball bearings (expensive) in bushing-equipped motors
improve its performance? By how many percent? Or it's just a waste of
money?
06. Both the RZ and FLR motors were fairly new but theres visible com wear
already. Should I use a lighter tension springs for the brushes or just use
the stock ones?
07. When to use light tension brush springs? Any disadvantage/advantage?
Im after longer brush/com wear and performance.
08. Is using a Racing 27T Stock Motor like Epic 27 or Co 27 Monster better
than the 23T motors?


Just need your based-on-experience opinion/theories...
