i used to run a 27single stock motor in a class specifically for it and then a 17 triple modified motor for an open class. tb i'm not sure what these would equate to nowadays? |
Brushless is what it says, coils now in the shell, magnet is the rotor all controlled by electronics, 2 bearings to drop some oil on now and again and your done, motors have 3 wires and a bunch of thin sensor cables, most can be adjusted in the esc profile, some button & flashing lights, some computer connected.
Lipo's - say 4000mAh, can run for 20 minutes I suppose, making everything a bit toasty, so in a 5 minute race they are still pumping out full power, beauty is they can be charged and used again, one battery all day, they have a good 'lifetime' as well. They are light and the cars fly with them in, most add weight to the car to help balance.
Your old 27turn could be 13 brushless, the 10's & 12's I used to put in our B4 are now replaced with 5.5 & 6.5 Novaks. You will not need anything lower than 5.5.
hope this is helpful, simple enough question that needs a longer answer I suspect, your yet to ask about 2.4g radio sets and where all the crystals and pegs have gone
