Truggy combos?
 

I have an MBX6-T with the RCM brushless conversion, and have started out with the RX8/2000 kv. combo on 5s lipo with a 20t pinion.

This showed out to be a way too fast setup, so I switched to 16t pinion.

But what are you guys running, I am hinking KV, how many lipocells an wht size pinion. I want to make it durable at a medium size track.

You can see the truggy here:

5S - 1700kv 46/16 gearing

for 2000kv on 5S go for 13t pinion

Thanks a lot.

What kind of temps are you guys running? I have a 8T 2.0 using the Tekin RX8 1700 combo and I am running 16/45. I am getting around 175 degrees on the motor. I have tried a 17 tooth also and it was about the same. This is on a large track after 10-15 minutes. I think this is too hot and might have to back to my Mamba Monster 2200 combo since it was way faster and cooler. Any advice would be appreciated.

Haven´t actually measured the temps, just realised the setup would be crazy for the track.

But I run the MMM on my Savage, and it runs way hotter than the Tekin combo, so I don´t think heat would be an issue.

I'm actually setup to run the same setup as Ellwood. 1700kv truggy with 16/46 gearing on 5S 4200mah Hyperions. Haven't run it yet but should be about right. Might drop to a 15T pinion depending.

Should be in the ball park.

I'm running a RX8/2000Kv T8 motor on my ST RR with 46/15 gearing.

George, how are you finding the power of the 2000kv setup? I think I read your running 5S with this setup?

Trying to round out a solid race setup that will be efficient without overpowering the truck. Hoping the 1700kv setup on 5S will be enough.

I do find the sensored option very nice for a race setup from a smoothness on part throttle or under braking.

Theoritically, a CC/neu 2200kV should be a little cooler than the Tekin 2000kV because it can handle theoritically more power. But the 16/45 gearing is too high with 5S 2000kV... you should try 13/45 maybe. The advantage of tekin truggy motor compared to standard CC/neu 2200kV are their low kV with high voltage.

Itbvolks, I only ran it twie for speed passes and so far I like it. I had to change the cd oil to 20 and increase punch control because it will wheelie the truggy or even flip it if I blip the throttle. I'm hoping to run it on the track this weekend.

Nuz, I wish I can use 45/13 as my setup. The spur and pinion won't even mesh with each other using the RCM kyosho mount.

Then maybe change the spur, what vehicle do you have ? Kyosho ST ? There is some 50 or 52 T spur .
Its better to have a big spur because you can use a big pinion for same ratio. And big pinion give mechanical energy to the spur with less loses than small pinions, the noise is also well reduced (motor temp too !!!!!) ;) and if the shimming is correct, the pinion will last a human life ^^

I like the 46/15 gearing so I don't plan in installing a bigger spur. I have Kyosho's metal and plastic spurs ranging from 44-52T :yes::yes:.

George,

So with the 2000kv setup on 5s, you have enough power to flip the truck running 15/46? How's the temps been? I still think my tekin 1700kv setup on 5s should have enough power/torque to handle a ~9.5lb truck without too much issue.

Really cool conversion though! Truck looks great!

Yes, but I think that ability to flip and ride wheelies are more due to the 30K cd oil I originally have in there plus running on asphalt. I didn't even bother to check the temp using my temp gun because it was really cool to the touch. I'll try to run it on the track this weekend and do a full test and see how the Tekin system runs with my current setup.

Btw, it's a Kyosho ST RR.

Itbvolks, I have the 1700 combo on 5S using 16/45. I ran pack after pack today at the track and never went above 145. The track temp was about 70. My heat issues were due to a bad solder joint and possibly a rear diff needing reshimmed.
