brushed speed

[samster]

what kind of speed would be capable with a 8 turn cobalt motor and is it the fastest brushed

[rcguy2477]

Around 45mph. Also, you must realize that with that low turn of a motor, you will have to cut the comm and put new brushes in every 2 runs.

Speed will depend on the gearing which in turn depends on where you run your car :)
On large tracks I have seen 19T go 45Mph and 12T 52Mph.

With the new XXX brushes supplied with the Cobalt you won't have to cut the comm every 2 or 3 runs and the brushes will last at least 30 runs.

Well I can see the brushes lasting that long on a mid turn modified motor but not an eight turn (even with their new brushes). Sure they will make it that far and still run pretty good, but if we are talking making the power to race with then I doubt it would still be as competitive as it was after 10 runs.

With modified motors the speed is not determined by the number of turns it has. You would obtain the same speed in the same vehicle if it were a 10 turn or 14turn. The number of turns generally relates to the power band motor develops. The reason you see a large variety in term of turns and winds to to taylor the motors power to better suit track conditions while still be able to make runtime. The Cobalt doesn't have much more power than previous Epic motors, and still some competitive racers prefer other brands of Modified (Yokomo-Reedy Ti, KR, Pt or TOP, Orion/Peak V2 version) for their power bands. The Cobalt is basically a D6 motor with the addition of the heatsinks and the can has been power coated blue.

Unless you have an assortment of pinions, plus a few spur gears (normally you use a taller spur than stock), extra brushes, springs you get better use out a machine wound at have the cost, and something in the 12-14 turn range (doubles) will produce the same speeds, have more runtime and less wear than a 8turn motor. I only use 8turns for oval racing and on some tracks that develops too much power or encounter runtime issues. I could run something like a 12 single, car doesn't have the rip (acceleration) of the turns but I am running the same speeds but finish stronger. Then for bashing I prefer 12-15 turn doubles.

The Most Powerful Motors at this time are:
Reedy Ti Worlds
Reedy KR

Orion/Peak V2
Fantom


I might go Brushless to get Better Speed and Less Worry.

Take Care.

The speed varies with the type of vehicle motor is put in. Offroad/TC vehicles would probably see the lowest speeds, more moving parts to rotate and weight to move. Pan cars depending on size of area could easily reach speeds of 55mph. On some large outdoor tracks when 6cells were used cars were reaching speeds of 80mph+ and averaging 65-68mph average speeds.
The key to getting the most speed is to gear the motor correctly, and tune it and chassis to perform at those speeds. Even with stock you may get 25-35mph with an offroad or touring cars some pan cars are averaging 52mph in stock with 4cells. Pan cars are lighter and have less rotating parts, the lighter smaller 1/12th cars are even faster.
