Question about brushless

[Vrooom666]

I would like to fit brushless system into my tamiya mini m-03. i run venom turn 15 motor, with mtroink esc.

Could M-03 chassis/gears take the power/strain of brushless power?

How long is the typical brushless run time is ?

How come they last longer run time on brushless setup?

Can i fit plane or helicoptor brushless motor into car?

What kinds of battery i can use on brushless setup?

Would regular tamiya style battery be enough?

Brushless in a Mini?

The car mentioned in a mini is a M03 (rwd) and is also for the sole

purpose of out-right speed. As for a M03 (fwd) with a brushless motor,

it would not be a good idea as it would be total uncontrollable.

 As for the other questions, that dependes on the set-up. Sure

brushless as more efficient than their brushed counterparts, yet the

efficiency still depends on winds.

Some of the helicopter motors and plane motors that are used are

outrunner style motors and are not so compatable with cars. Normal

batteries (ie standard good amp/hour) batteries are sufficient, yet a

higher amp/hour battery is recommended as most brushless set-ups are

low wind motors. Therefore as the rule goes for lower wind motors, the

standard Tamiya connecters are not good enough and should be changed to

such as a Deans plug.

well, a high KV BL outrunner motor and one of old busted hottness's motor adaptors (a while back he was selling some on another forum, not sure if he has any listed here or if he is still selling them tho) and some deans should work. plus, wheelspin won't be an issue (outrunners are VERY high torque, but it is controled, so a RWD buggy with one won't wheelie)

You could use a 6-pole inrunner, like the E-Flite Six series. It uses a 400 can with a 1/8 inch shaft. I believe the hole spacing is 25mm, but I'd have to check. For a lightweight rig like an M03 that would be a hot setup.With 2700KV, you're looking at about 24,000 rpm with six cells. Gear it high and that's more than enough for a Mini. The motor will handle it. You don't need or want a lot of torque in an M03.

Cyclon has just introduced a line of outrunners for cars and trucks, with higher than normal KV ratings but still with plenty of torque. You'd want to cut the Mini's chassis to ensure the wires didn't foul on the spinning can. I haven't tried one of the new Cyclons yet, but it's on my list of things to do.

Super insane speeds can be achieved using the Castle Creations Mamba Max system, up to 7700 KV (rpm/volt). They're rated for 80,000 rpm max (before the motor grenades).

Is that fast enough for you?

Hi all,

I run the Novak SS5800 setups in 4wd and 2wd vehicles.  Not tried a FWD car (got an M03 and an M03-L) but run times for speed are definite advantages.

The SS5800 runs at 40,000+ rpm (can also be put into sport mode - 27,000rpm max - perfect for a mini I would have thought) with oodles of torque.

Have to also say that I run Tamiya connectors with no issues either on 2WD or 4WD using 3600mah NIMH batteries (charged at 3.3amps).  Everyone seems to comment on how they are useless for these sorts of applications, but I can (and do quite often) run 2 - 3 battery packs through a single car in rapid succession on the SS5800 with no issues at all.

I get about 10 - 15 mins run-time out of the 3600mah batteries using a 4wd Top Force buggy with standard gearing and about 36mph top end on average (got 40mph out of it once under testing).  MUCH better speed and run-times than my old 12x2 motor (max 10 mins, mostly 5 mins).

Basically, I reckon the best reasons to get one are speed, torque, run-times and most importantly no maintenance!  No skimming coms and no replacing brushes!!!

Hope this is of some help.
