I'm sure you will work out a competitive price , when you do PM thanks as i will use it in my 2s speed record pan car .

Question on the speed car , do you think heavier lipos are better or lighter ones . I am looking at either the SMC 28c 4000mah or 5000mah packs , but i am thinking the heavier battery would help keep the car on the ground .

Any other battery you can recommend that will handle the amps drawn with the Vortex 2.5t motor and gearing you recommended . I have chosen the SMC packs as i know they will fit in the car i am buying and they are top quality cells .

2.00 with a bike is impressive , good luck on the challenge .
I'll let you know. I'm going to make a chassis for my TC3 that will allow 2 2S hard cased lipos to be used so I can wire them in parallel, so yes the weight will help you keep the car down. The 30C hard cased packs by Enerland will be plenty good. If you have 64P gears ditch them right now. I use 48P and if you're going to do speed runs use a 65T spur and the biggest pinion you can find, but you can basically use BrianG's calculator to give you an idea of what to gear the car for.

I will have to see if the Enerland 30c will fit the car? I don't have the car yet so i am waiting for guys to give me some measurements of what will fit in it .
Luci i ddin't think you could alter the chassis in the 2s speed scale class ? or is the TC3 for another use.

I am using a 48p 72T spur , couldn't find any smaller in 48p and will start with pinions from 22t - 26t as that's what i have at the moment , should get me going for now .

Well the chassis will be my aftermarket type chassis for the TC3. My TC3 has an after market chassis in it now. Everything else will be stock. If a dragster can be in the spec class, so can my TC3 :lol:. As for spur and pinion check this out:

Your a champ mate , RCMart is next door ( Asia ) and i usually receive products within 5 days from them . Now to go order some spurs and pinions :yipi:

Glad I can help a little and I only mean a little, because I have a nice 60T pinion to use with my HV1.5 and the 65T spur :whistle:.

ffactory666 10.21.2008 09:12 PM
I am about to put the order through for the spur / pinion and just had a look at there motors . They have the Orion Vortex 2.5t which is $20 dollars cheaper at $79 than the Speed Passions Competition 2.5t . Both rated at 13,800kv , i have not dealt with Speed passion before and don't mind paying more for it if it's a better motor but just haven't heard any reports on the SP motors ?

I'll have to have a look at Brians speed calculator to see what speeds i'm looking at with 13800kv and 65/40 gearing on 2s :gasp:

Why aren't you sleeping man , it's lunch time down under :smile:

Ok just used Brians calculator , with above set up it's showing 104mph but the motor will be spinning at 102000 rpm :surprised: they are only rated to 70000rpm that motor will disintegrate :smile:

Now if i use a motor around 9000kv with the same 65/40 gearing the calculator is showing 157mph :surprised: with the motor at 66000 rpm which is within the limits .

I don't understand how using a lower kv motor will yield more speed , maybe the calculator is not working right .

I put 1/1 in the differential section since the pan car is direct drive and 2.5" for the tires since that's what foams come in un cut ?

I had my 2.5T screaming for a little while doing some testing on that windy day and the motor is still good.The motor should be able to handle 102,000rpm, but if you're worried, just wait for my motor to come. It should have the rotor wrapped with Kevlar. I'm not sure how Brian's calculator work, but it give a high percent of speed loss with the higher rpm rating.

I think it must have something to do with efficiency loss , not sure .

Think i'll order the Orion in 3.5t which is 9130kv , thats 67562 rpm with 2s and theoretical top speed of 157mph with the 65/40 gearing .

Heck i haven't even driven anything over 60mph ,and even with the 72t spur and 25t pinion i already have , that's 129mph theoretical top speed which one of these pan cars would not handle too well anyway without being modified and niether would the driver :mdr:

I think i'll be happy with a car that handles and can get over the 85.45mph record in the scale class .
Maybe the above speeds would be nice if attemting the open world record of 161mph but not for me at the moment .

Lutach,

any word on when the 200A escs will be available?

They should be coming in soon now. It takes a little extra time to make them.

lincpimp 10.23.2008 02:07 PM
Hey Luciano, got the esc in today. How do I go about hooking up the program card? Just plug the rec wire ito the slot on the card and also plug in a rx nimh pack into the card too? I see it has two areas to plug into. Also, do I have to have a pack plugged into the esc during programming?

Just plug the ESC's Rx plug and plug your pack to the esc and turn it on. It should power the program box and then you go through the settings that you need and press OK every time you change something before you jump to the other setting. You can also plug an Rx pack, but it's only needed when the ESC's BEC is disabled. I can make a quick video if you need :tongue:.

Ok, got it, thanks!

lutach 10.24.2008 04:08 PM
The 100A, 200A and a few motors have shipped and I sould be able to track it tomorrow. They should be here in about 5 days. Now here is my problem, the only system out there that's like the 200A one is the RS Pro, but the RS Pro is smaller. I will post some pictures of when everything gets here. I can't wait to try out the 1.5T and 3T 540 motors.

snellemin 10.24.2008 04:15 PM
Does yours have the same features as the RSPRO does? What's the power wire AWG? Will cost be similar to the RSPRO?

Both my ESC have the hybrid sensored/sensorless function. Mine comes with a program box for easy set up. The 200A 10GA power wires (That's what the sample unit I have here has). It will not cost the same as the RS Pro, it'll be a bit cheaper.

snellemin 10.24.2008 04:32 PM
aaaaaw fat wires get me hot. I just blew my money on some things I needed to stress out your other ESC, so it will be a bit longer before I get one from you to abuse. However, HOLD ONE for me.

:lol:. Man, when lincpimp sees that you like fat wires, you're in trouble :rofl:. Linc is testing a 100A sensored and I asked him to post any feedback here. I like how you're beating the crap out of the 1/8 scale ESC.

snellemin 10.24.2008 04:45 PM
Yea I figured lincpimp would get a kick out of that one after I posted it.

The 1/8 scale ESC is doing very well so far. If it passes my last test, then it was money well spent.

lutach 10.29.2008 07:39 PM
Hey linc,

Any good news on how the ESC does in the crawler? Let me know if it's working good and would a 50-60A sensored esc be better as the crawlers don't use a lot of amps?

Regards.

tom255 10.30.2008 01:47 AM
60A ESC in crawler is more than enoug.
One guy using in his 2.2 class crawler 22A Quark, and it works perfect!

lutach 11.01.2008 02:23 PM
The ESCs and motors are here. The 1.5T has a Kv of 18102rpm, it would have been higher, but the factory opted to use the rotor with a fan, so the Kv is lower and I'm hoping it'll work as planned. All the high Kv motors have Kevlar wrapped magnets. I'm going to push for the 2T and 1T delta motors as they seem a lot easier to do then the Y ones. All the 200A version comes with 10GA power wires and they look great.

BL_RV0 11.01.2008 03:53 PM
What KV do the rotors stay kevlar-wrapped until?

DwightSchrute 11.01.2008 03:53 PM
Lutach,

PM sent

snellemin 11.20.2008 05:44 PM
I received the 200A esc last nite. Fast shipping as usual.

I left a first impression review Here and the problem I encountered.

Let me know how your testing goes snellemin after you add your caps.

lutach 11.20.2008 05:49 PM
Hey lincpimp,

How is the 100A doing in the crawler?

lutach 11.25.2008 05:25 PM
Little update:

I was talking with the factory last night and I asked for a new capacitor set up for the ESCs. In about 5 minutes the engineer had made 2 types to show me. I decided to go with the one with 4 small caps as it packs the most punch. They might also do 2 crazy ESCs and if they do make them, I'll post something here ASAP. Here are the pics:

Looks nice.

snellemin 11.30.2008 07:31 AM
I hooked up the 4800kv Medusa onto the Rustler with the heavy beadlocks and Imex tires. With the use of a cold 3s1p A123, 200A ESC, 58/25 gearing, it pulled my voltage down to 4.39V@153A, peak 786W. I'll drive it around through grass tomorrow and see how the motor and esc behave.

lutach 11.30.2008 10:13 AM
Nice. Did you have any stuttering issues? How was the start ups? I asked the factory to do their best for the ESC to work good in sensorless mode with 4 pole and higher motors and they're waiting for some info. I told them I tested my Neu 1515/1.5Y with 4S unloaded and it didn't have any issues.

snellemin 11.30.2008 02:45 PM
Did another run w/3s2p A123 and peaked it at 182A@5.88V with a peak of 1204Watts. In 4 minutes I consumed 1400mah.

The ESC is really smooth with the medusa. No cogging whatsoever.

http://i189.photobucket.com/albums/z...edusa58-25.jpg

lutach 11.30.2008 03:20 PM
Nice. The ESC is sure putting out a lot of power. Almost at its peak. It'll be nice to see someone that has a Tekin RS Pro try the same thing. I wish the weather was better here so I can do some runs as well. I guess me buggin' them to make sure the ESC will work good with a multi pole motor paid off :lol:.

BL_RV0 11.30.2008 05:06 PM
That's good. I'm planning a 1/10 project and will need 2 escs.

snellemin 12.03.2008 03:54 AM
I just tried a silly 9/44 32P gearing in my big pan car, running the 2.5T motor on 3s1p A123 in my garage. It moved forward everytime and smoothly at that. But take out the sensor cable and you get some serious cogging. I need VHT to put some load on this motor.
