What suits the 1930/5 turn motor?
 

Hi. Need some help finding the best controller to go with my 1930/5 motor( I bought it 6 months ago) which I will be using it in my B4 buggy at 16.8 volts with 10.8:1 FDR. I think the 9920 is very good, but a more powerful controller would do the job even better. I know that 14 cells is quite an overkill to the car and the motor, but I'm looking for speed records and I've been dreaming of hitting the 80s( in miles, that is). If I was able to get myself a 4 cells lithium pack with 10000 mah capacity from Thunder Power, then the job would've been pretty easy to feed the motor with hi amperage rate, but lithium costs money and I dont have enough to get them. So any suggestions? Just focus on the controller for now.:) thanks beforhand.

Well, the 12020 warrior would be the next step up. If you aren't thermalling the warrior you have, you won't notice any difference in performace by switching controllers, though.

I want to understand something, if the motor sucks up a 150amps surge and the controller is able to pull 110-120 amps surge will that cause any trouble? BTW, the 12020 is not available. Are you planning to bring in some more?

If a motor pulls the amps, and there is no current limiter, then either the controller will provide the amps (and get HOT), or it blows. Usually it just supplies the amps and gets hot, then if it has temperature protection that kicks in.

I have 20/120 and 20150 controllers ordered. Just am,atter of them arriving. The latest news is that the controllers are still a couple weeks away(today I spoke w/BK). The board mfg was on holiday for 4 weeks, so they were unable to get the needed supplies! The Micro series controllers are a bit more expensive, but also have lower resistance and more programming options. Not that you would notice this a great deal in your application, though.
The 99 amp controller can handle surges up around 140 amps for short term (10 seconds). Power in = power out. The amp rating on the controller won't determine the amount of power that goes to the wheels. This is just what it is rated to handle. Cells, gearing etc. are the factors that determine speed/power.

You seriously shooting for some 80 mph runs. That sounds awesome. Let us know how that works out. That would be the bomb. :lol

one little rock will send it right to the moon (or thru the moon..) be sure to shoot a movie for us! (sensationmode=ON)

It would be a blast before and after that rock though. I wish i could be there. Show me to the radar gun.

The B4 is definately the car to do it it! I have access to a Lehner 2800xl and a BK9020 and I do have a B4...I might have to try to set a speed record of my own!

Hey camel you could take it out to the salt flats. Blast it down through there on time. I think the record is 110mph. I believe. Set it with a brushed motor. We can't have that. Brushless rules. :)

I see that you have already been tempted by my phillosophy in this hobby Coolhandcountry. Speed is almost the perfect definition for rc hobbies. Wish you a fassssssst and crazy ride, buddy;) .

I have had one in the 50s. It gets hard to drive. I like to try to get mine back up around 60 now. I stretched it out some and man does it handle great. I love speed and power. No matter if it is car or rc. I love it. I been 140 mph in a car. What a rush. Have you ever seen the 200mph lether cars run. They may be on cables but man they fast.

110 mph? bet it wasn't an emaxx..

87mph here I come.

WarpSpeed...

You'll be in the US within a few minutes with that speed..

Nope wasn't an emaxx. It was a four wheel drive car. I still thought that it was pretty fast. http://www.rccaraction.com/rc/articles/need_speed.asp
Here is the link if you like to read about it.

That's the tc3 of Mr. Cliff Litt who is the leader of the R&D department of AE. He used a 12 turn brushed motor with cobalt magnets and a brushed speed controller supposed to handle 7 cells at most, but he put 14 cells all at once and used a 4.?:1 FDR, however, the car was able to reach 96mph and not 110 mph, but it was the rc10l3 modified version of the usual ones which made an amazing 111mph using 24 cells with an AVEOX sensored brushless motor and a 2.4:1 FDR. I believe that a pan car with a modern brushless system like a 1930/5 motor and only 12-14 cells would be able to push the pan car beyond 100mph with absolute ease. I thought of missing around with my own l3 and bolt in a Kontronik fun-500-2700(kv) along with a pack of 22 cells and use a 1.9:1 FDR, but its quite costy and that is why I'm going to try my luck with the B4/1930 5T/ 14cells setup and see if I'm able to push it as fast as 87-89mph like when Mr. Cliff pushed his tc3 to 96mph using a typical brushed motor with a pair of magnets which I believe them to be weaker than the neodym magnets that are been used nowadays in sensorless brushless motors. Also I need to find a way to increase the center of gravity of my B4 and make the clearance of the chassis as low as 5-8mm. O'God grant me luck.

IF you run the lipo packs seem you would loose some weight and gain some speed. Less make it easier for motor to push it to the speed. I can't imagine a rc going that fast. IT is flying. I watched the tether car video to. I know they don't drive them but man. 200mph. It is a blur. I save all the video I can. I love to watch them. It is neat.

The one that made 200 mph was tying the car with a rope and rotating it inside a sircular track. I dont wnt to be tied......I want to FLYYYYYYYYYYYYYYYYYYYYYY. See you later Coolhandcountry.

You have to admit 200mph is good. tied or not. Get a video of that flying if you can. I would love to see it.

If you have got the 36120 and the 2280 lets see what 36 cells on a Tamiya grasshopper will do Coolhand..

You went toooooo far, Serum.

What is a grass hopper? I not sure. It sounds like it would be a killer set up. If I get the stuff. You help me build and shoot the video. :)

You really dont want to try it out, buddy. The grass hopper is an ancient buggy(2wd) made by Tamiya in the late 70s-early 80s. You dont even have a place to put 32 cells not even 8cells and the drive train as well as the suspension system would be easily destroyed by a normal brushless setup like a 5300/9920. It was a joke, though, what serum said.
