our track here in florida runs between 150-160 degrees.i run my 4.5 with no fan on the motor.i gear it at 10.125 and i am not a big brake user.i just stab them quickly on corner entry.my motor comes off about 170 degrees and my speedo about 140 degrees.i want to put a fan on the motor to drop the temp a bit but it has not thermaled

I will try not to stab at the breaks and become a touch bit smoother but my lines with a brushed motor and brakes are impossible to drive with the brushless. Time to find out what I'm made of I guess

Probably no problem, you just need to find a SUNON fan supplier, the farnell link was to get the correct item number from Sunon and for you to see some of the specs.

They'll probably have Sunon in somewhat every electronics store or they can order it.

2 questions:

I have a 5.5 that I use in a 4 cells Mini RS4 chassis, do I need the Novak capacitor? I don't have a lot of room in this chassis and I wanted to know if it was possible to remove it.
Did someone ever tried to dye the orange case in black???
Thanks a lot .

I've successfully run a 5.5R and GTB system in my 1/12th car - including the 2006 Euros and recent 1/12th Worlds in Italy

The only setting change I've made is to lower the initial drive - from factory setting to the lowest. That gives a better response on initial throttle movement.

My 1/12th runs with a reciever pack. That keeps the RX voltage up, and I;ve trieed running both with and without the Novak capacitor fitted. Didn't seem to make any difference taking it off....

Also ran without the GTB fan fitted - even with the fan off the GTB only fits under competivie 1/12th bodies if they are cut well below the cut-lines! Given Italy and the Euros were very hot, no thermal issues...probably because we only run 4-cells.

Hope that helps. A braver man would have tried the 4.5R...mind you the 5.5R in a 1/12th is plenty fast enough

Hope that helps

MarkB-would you mind shooting a picture and posting it?

I have now put several battery packs through my 5.5 velociti//gtb in my XRay and I got to say its quite stout as well. Feels very 8x1 like. I am still struggling a bit with it feeling like its got drag brake in slow corners and I keep having to drive slow corners at partial throttle which is not that easy on foams. I turned the drag brake off and have no drag in my radio.

When I run a brushed 7 or 8 turn I like to lift off throttle into corners and "freewheel" mid corner and start to roll back into it. Its hard to get used to having to leave throttle input in mid corner.

Last time out was much better with the help from Jason at BMI. Came in second at the yearly Revo race with the brushless. I have even more things to try the next time out after talking with Charlie. It's looking pretty good though. I didn't have to cut a motor all day

The capacitor is just a boost bottle (nitro term), essentially. All it does is help with acceleration. Capacitors can dump power FAR quicket than a battery can. So under braking or coasting, when power from the batts isn't being used, the capacitor takes in power. Then when throttle is applied, especially if full throttle is applied, the capacitor dumps all of it's power in an instant so you get instant and maximum acceleration. The only difference between having the cap and not having it will be acceleration.

The cap also aids in keeping the speed control cooler. Removing the cap will void the warranty. So I wouldn't remove it. But ultimately the choice is yours.

Thats weird, i had directly the opposite feel in my car. without the resistance that a brush motor has, i had to brake in the corners more compared to my brushed motors, as the BL free wheels very very well. The motor with no drag brake and no throttle input should free wheel forever (within reason lol). My car is very free, but i do occasionally use the drag brakes (me being slack), but without the drag brakes, i can sometimes over shoot corners.

Testing the 5.5r in a 10 pan, 4.5r in a MSX and a 5.5r in a 1/5 bike, on asphalt this weekend. Ill tell all how it went

And how does it aid in cooling?

Even Novak doesn't say it aids in cooling. They say the fan does, but not the cap.

The supplementary notes included with the GTB mention that the power cap makes the ESC run cooler because it increases the ESC's efficiency.

Ahh. Increasing effenciency by making sure that when full throttle is applied, and the flood gates open wide, the motor gets as much power as it wants right away, I bet. If it didn't the motor would be trying to pull power through which the batts couldn't supply and then things would start to heat up.

Anyone know if that's correct?
