That's about right. The higher Kv motors are a few grams lighter (but not much!) than the lower Kv motors.

Thanx!

So the SCT will be a special 1409 series with the can shortened to fit under the ROAR 53mm length?

This is the headache we 4x4 SCT racers are facing, motors that actually work for our trucks. I swear it's the only bit of buyer's remorse I have regarding my SCRT10.

Yeah, it's as much stator and rotor as can be crammed into the 53.00mm maximum dimension. Works very well.

You guys might want to edit your Xmas list it looks like these motors are shipping!

I'm going to wait for ROAR to pull their heads out of their rears and makes some 4x4 SCT rules before I buy a motor.

Not that CC's SCT motor isn't great, but I am holding on to hope that they allow longer cans...because if the 1409 is a good motor for 4x4 SCT, a 1412 will be even better.

Hear that Patrick? Light a fire under those guys, and we, the people who are conservative with our wallets, will open them up.

Right now I have a Monster, a Lehner Basic XXL, and a track that doesn't care about motors. I'm happy.

Sure, I can see where your coming from. The 4x4 class is a mess around here. I was referring to the 1406 hitting the streets for the 2x4's, TC's and speed freaks.(dragsters:wink:)

Patrick, please read:
 

I'd like to add my experiences with the 1406-7700 motor in my 1/10 funny car over the last few weeks.

The first attempt to run this motor was at Autorama 2010 at George R. Brown Convention Center at a RC drag racing exhibition race November 25 - 28, 2010. That didn't go over too well in that the track was way too sticky for any fast numbers. I noticed that this motor has a lot more torque than I anticipated, which meant I had to use wide tires as well as more torque control than I wanted to. The stickyness of the track meant that with the lower available torque start off was sluggish, but the top end was good. The best I could manage was a 1.7s ET.

At this point I decided that further testing at this location was futile and should be continued at the next race in San Antonio, which would be the final race of the 2010 Texas Twister Race Series, held last Saturday (12/11/10). So the car was set up like it was at Autorama: MMM ESC, TP 4200 3S Lipo, weight at 49oz, 4.30:1 gearing, 2.8" tires. This was good for 1.563s @ 84.1mph in the 2nd round of qualifying, and got me the TQ.

It got cold quick after that and ET's didn't go down any further due to low lipo performance in the cold. However, I went on to win the class with 1.6s ET runs in the next few rounds into the finals, where I ran a 1.7s (it got colder still!).

So, here are my thoughts about this motor. Toque monster!!! With the lipo discharge levels that we run, this motor creates gobs and gobs of tire shredding torque with extreme ease. I have to get more familiar with the Torque Limit settings a little more in order to really unleash some fast ET's. One thing that I really like about the motor was how smooth it was when everything was dialed in. That 1.563s pass was so smooth all the way down the track. Now the trick is to keep that smoothness going into faster ET's, which should be no problem as I run it more and more and get a feel for its power characteristics. My attempts will continue next season as we have already closed out 2010 and will post updates as they come.

My thanks and deep gratitude go to Patrick and the awesome folks at Castle for getting me this jewel of a motor to race with.

Had a chance the other night to put some more track time on the 1406 4600 kv at west coast. The track right now is very tight and technical. Every time I run it I like it more. So smooth and gobs of bottom end. Was eatin the 550's up all over the infield with the 2s setup. Motor never seems to get over around 150 even with 10-15 degrees of timing. Didn't really notice much in the way of speed with the timing on the tight track but it seemed to make the motor a little smoother on acceleration. This thing tosses my 6 lb 4x4 slash around very well. Not to mention it's a bit lighter than my 550 was so I can run softer springs in the rear for some more on power traction. Ran a few laps with 3s too geared for the same 40 mph and noticed a little more snap but not really a tight track setup IMO. Overall I'm really impressed with the little green guy and so are the people who end up pitting by me. Everyone runs 550's and so did I on 3s and everyone knows that. But when they see the 540 and a two cell smashin around the track the questions fly. Will continue to run it and when I get a chance race too to se exactly how it stands up to the stiff competition at west coast. Many thanks to Patrick and all the castle folks for doin what they do.

Got a new "testbed" for 2011 :yipi: Since my other TFD was doing so well, I decided not to use it for testing (don't fix what's not broken) and decided to buy this one for that purpose. Since this is a "sidewinder" chassis, I'll have another parameter (gearing) that I can play with, useful for testing the Castle Creations 1406-7700Kv motor. It's geared 4:1 and has the 1406-7700 already installed along with a Mamba Monster ESC. I just couldn't wait too long without putting it together :lol: Without a battery she weighs in at 26.8 oz. I'm also very tempted to use this car as a stepping stone into Extreme in 2011.

Sunny How do you combat the time delay made by the Esc trying to detect rotor position since your running sensorless?


I raced a friends pro mod carwith a 9000kv on 2s and the thing would either leave like a rocketship or stutter back and forth for about a tenth of a second then take off.

I think the most important thing is to have a battery capable of discharging enough current to overcome the initial launch. To that end, the 40C TP packs have proven exceptional (that's all I use for the most part, save for a couple of 50C 2S packs). Also, I use "high start power" as a default (less if the track is slick), which again require good batteries.

Also, tire prep is important. You need to use some Koford, or similar, traction compound which serves two functions at the same time. It lets the car stick to the track on launch and its viscosity lets the tires slip a little, which helps helps the motor "power through" the launch. If you don't put enough of it, the car can stick to the VHT on the track and not move/stutter.

Even through all this, the car sometimes does the "Mamba Shuffle" simply because. For me that happens less than 5% of the time I think.

Hey CC folk,

I haven't seen the SCT motor only for sale. I have a MMM and don't need another ESC. Any idea when or where I can find just the motor?

We have not released the 1410/1Y 3800kv and the 1415/1Y 2400kv motor's by themselves. We are working on getting some in soon, I'll be sure to put up a post when they're available.

Sweet! I bet those will be popular selling motors, particularly the 3800kv one as a VXL replacement.

Update for anyone who still cares, been running the 4600 in my slash LCG (RASH) conversion with great results. 2s geared 27/84 with no timing and low start power. works really well and has power all over the place. topend is quite impressive, just ask the 1/8 scale buggies i was pacin down the straight. still cant get the motor over 150, ran it for ten minutes straight last time at the track and it was 148. this motor is waaayyyy efficient, my 13.5 wont run for ten minutes or at these temps geared this way. many thanks to all the cc folks and especially Patrick for all the help and great products. looking forward to whats on the horizon from cc....
