That is a sweet lookin' mini! HotnCold has a rc18t with the 8000kv lipo. I am waiting for the outrunner system for my rc18. I never dug the mini t, as I pretty much am mostly interested in 4 wheel drive (although I still like my stampede).

You can lower it real good, not to much wheelies now..

(roaduse) chassis is about 1 cm above the road.

I drove it a few days ago, not one single flipover.. fulspeed, nice long speedrun... And suddenly.. there he was... That monster..

My sisters Berner Sennen.. hit the poor monster at full speed.. The only plastic piece making part of the frame shredded in pieces..

And the dog didn't move a mustle.. He's affraid of my savage though.. (good for him to..)

And yes, 4wd is an easier ride! Just love the 2wd little nervous thing. Reminds me of my old tamiya frog.. Good oll' frog!

Lipomaxx,

I have been playing around with the lipos for a little while, and I have read a ton of info and safety stuff regarding them. I also completely agree with the high voltage, low Kv motor practice. I just happen to have the hacker c48s already. I really like the basic 4200 in the tc3, but I have been interested in the smaller rotor motors to see if becomes more tractable/driveable. I have also thought about running the cells in series on a basic 2100 motor. Performance should be similar (well, on paper, the performance would be identical), but I woder if the setup would run cooler for longer than the 4200 and parallel cells. Have you tried similar setups in your TC? I know you have a data reader and wonder if you have graphed any similar testing information. I am certainly interested in this info.

Actually, I've done test on a c406s (7000) with 2 cells vs. a c4012s (3500) with 4cells. The 12s is much more efficient than the 6s. Theoretically, RPM should be the same, but because there is less voltage sag, the RPM is higher with the slower motor and higher voltage. In addition, everything did run MUCH cooler and did not thermal the controller.

I don't believe you'll gain much going slower than 3000 rpm/volt. It seems that the small RC motors seem to peter out around 90% efficiency. So going 6s on 2100 isn't going to be much of an improvement vs. 4s on the 3100. But definitely an improvement over 3s on the 4200.

Going with a smaller lighter rotor doesn't make the car more driveable - it makes it more BALLISTIC! Acceleration is instataneous.. snappy... no spool up. When comparing the B506s (like a Feigao 6s), it was actually slower and pretty lazy on the track in my XXX-S G+. Going to the basic motor, it was definitely faster and still kinda smooth. Going to the c40, it was even quicker - so quick! I wish I had a vid. of my tc4 with 4s with the c4012s motor. Geared only 10:1, top speed is around 40 mph but it'll get there sooooo fast. If traction wasn't such an issue, I'm pretty sure I can do 0-40 in 1 second. I think I read the last RCCA and the TC4 did 0-40 in like 2 seonds with the 12 turn motor (if I remember correctly).

Another reason I have a hard time justifying going above 4s in a TC is packaging. It's hard to find a 6s pack to fit into stock TCs - the Kokam 2000's do fit - but you have to have them end to end and they barely fit. In addition, I really like the U-Force 75 for my TC4. I used to use the 12.97 fwe but that was difficult to place. The Hacker Master was kinda jerky and for some odd reason, there was always a slight lag at startup - not cogging, but literally a lag of about 1/4 to 1/2 second when I hit the gas.

I have had the same experience with the Hacker controller. I have an 18.97 in the tc3 now (not the kw/kwf - no heatsink) and I can't complain. I think the smaller motors have a slight advantage in acceleration, but the setup I have now is definately no slouch(don't think I need it to be any quicker!)! I have heard good things about the u-force, but I haven't tried one. Schulze is not famous for warranty backing (in fact, they always find a reason it was the users fault!). They are slow to turn things around, too. But that is partially because they are so far away. BK is definately quicker and seems to back their product pretty well, too (not that Schulze doesn't have killer stuff, but when it fails, it gets expensive - and they aren't cheap to begin with!). I have heard good things about the mgm controllers, too.
i am set up as a dealer with them, too. I just haven't had the budgetary means to add them to the lineup yet.

The 18.97 is a great controller no doubt, but the lack of BEC makes it difficult to package into a TC. In addition, the U Force 75, even though it's has less amperage rating, I believe can probably run more constant current due to the heatsinks. also, the controller is just about watertight too. The U Force can also be adjusted - one of the aggravating things about the "future" is that they really can't program any kind of drag brake unless you really fool around with your controller. Makes it kinda hard to drive. With the U Force, you can actually setup drag brake, min. voltage, and has unfortunately a 5.0 volt BEC... but it's still built in. I had a Micro1895 about 2 years ago or so and it was okay, but it cogged and wasn't quite as smooth as Schulze - plus they cost more! I might try the MGM if I hear a lot of good things... but I'm waiting for a 50 volt 100 amp version from Castle Creations for a 14s lipo setup on my emaxx!!! I'm going to need a 1200 kv motor soon!

Castle is currently working an a new mamba, but they will sell it in combination with a motor. They are currently looking for a motor that is more efficient.. (they tried all sorts of different brands/types) The controller was ready, that's what i understood.

BK is also working on a pair of controllers that are said (By BK) to be designed with the 1/10 car in mind. I spoke with Alex and he said the low cell count cogging is gone. There will be two versions (60 amp and 95 amp), both rated for 12 cells. The 60 amp version will be out first. I should have one for testing in a month or so. The 60 amp version has already been tested in a touring car by a big name on road racer and is said to be very smooth at all speeds. I hope they are as good as they sound. The price will be around the warrior price range or slightly less as well!
I agree that the u-force could likely handle more continuos current. I actually think the 18.61 with a heatsink ("k") can handle more current, based on trying them both in my e-maxx.

Petty they are only for 12 cells..

So is the U-force. These will be half the price and sound like they will work just as well for brushless (no brushed on these, though-I never run brushed motors anymore anyway).

I see, they aim for a different goal.

Won't take long before the overpriced matter on the BL controllers is gone..

Guess another 1-2 years and you can get a BL setup for a 1/10th for about 140 dollars.

These controller and The Feigao motors (BK is also developing a new motor i the Feigao price range with "Lehner quality") should be around the $200 mark for the full set-up. Pretty close to a high end brushed setup, but more performance and less maintenance.

That sounds pretty good - maybe Roar will have more general rules regarding brushless - within a certain size like 540 and also have a limit on price so retail can not be more than say 85 bucks! Sensored or non sensored.
