Is there such a thing as too much power?
Why cant I use the MambaMax system in my MT?
I thought the MambaMax could only run on 3s lipo?

Why is BL better than brushed?
Numerous reasons. BL motors have far fewer parts to wear out, so maintenance is generally just
a drop of oil on the bearings every now and then, and perhaps a blast of compressed air to
remove any dust or dirt inside the motor. Because of this, your typical BL motor will last for years
and years with constant use, where as brushed motors will require their brushes changed and
coms skimmed etc etc.
Why does BL require lipo so much?
A BL motor the same size as your typical 550 motor is many times more powerful, but in order to
make that power, it needs batteries that can supply it (in the form of high current flow, measured
in amps). Nimh batteries are good for about 70amps or so, as I am reliably informed, but BL
setups are much happier with more like 80-100amps typically; if the battery cant keep up with
demand, it will rapidly overheat. In the case of nimhs, they explode, and lipos will generally
‘puff’; death by over-current in either case.
Which brand of motor is best?
Novak systems aside, then my personal list would go like this:
1)Neu
2)CastleCreations
3)Lehner
4)Hacker
5)MedusaResearch
6)TeamTekin T8
7)HobbyWing
8)Leopard motors
9)Feigao
Obviously there are many more brands and manufacturers, but those are the main ones you will
likely encounter. My personal choice for a high budget build would be Neu, blue or black variety.
For a mid range budget, I’d go for the Medusa or Castle motors, and then the Leopard motors for
a low budget build. Feigao work fine, but they are prone to running hot and broken magnets are
all too common compared to the better brands. Hacker and Lehner are European brands, so you
are far less likely to find yourself buying one, plus the prices are somewhat astronomical. I
missed PlettenBerg off the list since again, although they really are the best of the best, they
cost more than your truck will generally speaking, so only uber rich dudes will find one of those
on their shopping list.
