the 13.5 setup is worth the few extra bucks upfront..probably around 30 more than a brushed setup...in 3 weeks i've already save about 15 bucks in brushes and springs. I'm getting ready to order another GTB to place in my other car.

I've noticed that my lap times are pretty close when comparing runs with a top tuned motor and the 13.5 ....
but instead of getting that optimum lap once every 3rd or 4th week when i placed a new motor in the car...I'm getting it every run...
actually started to pick up way more consistent runs now...lap after lap...only thing holding me back now is my driving

I find myself now knowing when to throttle way more smoother than before.

Oly,

MLP thread is kinda quiet what's going on? How's your car going?

Back to the topic:

Right now I'm considering getting a mamba for mod class at my club Co'z I heard GTB have problem on thermal over heating when running low turn motor.

But for stock I'm looking for used GTB do you know anybody selling one?

You can get 13.5 from tower too.

http://www2.towerhobbies.com/cgi-bin...?&I=LXNJA2&P=7

Tower has $15 off $125. If u don't live in Tower's state, there is no tax. I just ordered two more 13.5. You can try 014ML to get $20 off for $150. Getting two 13.5 will get u over $150. at $68 each shipped (I joined tower's prefer club I get free shipping for $150) It is pretty good price.

Just trying to help fellow racers save some money.

SS4300 is a 10.5 T. SS 5300 is a 8.5 T. using either one will be too much for stock racing.

Geeze... Haven't run the car but on my kitchen floor so far but this motor has some torque... Playing with the throttle on my 12th scale on the stand and I'm watching the pod jump...

Is the motor a little noisy??? Or is it me????

our track has been mixing in 13.5 in the ROAR 27T stock class in sedan and oval classes.

13.5 sedan up'd a record in stock by a lap, it was the 2nd week this guy had it, and to top that...it was in a FT-TC3. the CO27 has been somewhat equal with the 13.5. over-all brushed motors still tend to win more, but that is because the better drivers are not willing to change yet. so far there has been no disputes in the class over the mix.

today was the first day they ran the 13.5 in Stock 1/10 pan car oval, busted the track record by a lap without even really getting it totally figured out yet. the record was held for the last 8 months by a sponsored driver. they started arguing over the mix before they ran the first 13.5 in this class.

to me the BL is the greatest thing coming down the pike. but on the 13.5, to me it doesn't appear to be a 27T equivilent under racing conditions. overall seems more like a 25/26T motor. sort of like the 4300 vs 19T. they were supposed to be equal but overall the 19T tends to be equal 4 minute races and 4300 with all the mods rule in 5-min races.

one thing that i can agree on with some is that: since the 13.5 has bearings why shouldn't the 27T guys be allowed bearings. our track won't let them and holds them to ROAR rules. the 13.5 does have bearings and rare earth magnets not allowed in brushed motors.

I would not even start the argument up about magnets. The two motor types can not be easily compared to each other. The only comparision will be in lap times. Novak was supposed to have tested and built something that ran comparable lap times to brushed. My guess is they used good tuned motors and not somthing they just ran down to the store and picked up. I also think you can gear these things higher. I am willing to bet there are some cases where a brushed motor will be kicking this motors rear.

I just got back my remanufactured SS5800 system from novak but it doesn't have that special tubing around the sensor wires. Is that something that is supposed to come with the SS5800 system or I have to do myself. I bought my SS5800 system used so I don't know if that tubing was from the factory or not.

Also, if I buy 2 GTB fans (I just bought a used GTB that needed some fixing up) from TowerHobbies, will it include the necessary mounting screws and mounts?

Ran it in my 12th scale today and wow.... I couldn't gear it up enough, actually screwed up my pod plate on my CK because the motor was up against the pivot. Wish my LHS had the 88 tooth gear... Oh well.... I ended the day at 96/34 gearing and it was coming off the track with the motor slightly warm and the ESC ice cold (no fan btw...)

How can you tell new endbell (sintered rotor capable) vs old endbell???

There are many 88T spur manufacturers, but only Robinson Racing makes smaller than 88T. They make some nice small 78T, 81T, and 85T spurs.

You shouldn't need anything smaller than a 92 spur with the 13.5 in 12th. You can hang a pretty insane gear with a 92. PRS makes one...

I don't think that the sintered rotor will make the 13.5 much faster (if any) but it does make the car drive more like a brushed motor.

You can find a sweet spot with the gearing on the straights. If you overgear it it won't go any faster on the straight and you'll just lose punch. May be a different story on oval though.

Problem arises when you (like me) run your tires small.... My rears were around 43mm and I still needed more gear.... I had the motor pushed against the pivot plate to get a 34 tooth in there which caused me to screw up the rear pod when I took a hit....

James, thanks for the links... I ordered some 78 tooth gears to have them, hopefully they'll be here before friday....

The motor just felt so much better at the 5 minute mark....

the 4300-5800 don't come with the large front bearing and rotor upgrade ($30 extra). If your 13.5 doesn't have these contact Novak. I bought two that didn't and they sent the upgrades to me FOC. The sintered rotor in the 13.5 helps with breaking and motor temps, like 30 degrees cooler. Helped me to gear properly for a couple of local carpet tracks
