Woops I was wrong about the schulze, I didn't realize it was an "L" model. For $220.00 that's looking like a good option.

IrishChamp 04.05.2012 03:08 PM

Maybe I was looking at the Jazz manual.

Do you think the 40.100 Schilz Furure L would be adequate for my build? 100 amps continuous would be cutting it close but if it has headroom like the kontronik esc's it might be enough.

I've heard that the older 40.160 would regularly burst to over 300A on big airplanes. Mine came close to 200A when I used it with my Neu 1521/1Y a couple of times on 10S which I don't recommend. I really don't know how the new ESCs are built and if they have the same capabilities of the older units. If you keep your speed bellow 40mph (without tire ballooning), you might be able to keep you burst AMPs to about 100A and you could average around 20-30A (Maybe lower). At the moment, I take any ESC rating as the burst AMP rating which occurs mostly on hard accelerations. If I were you, I would contact Schulze first and ask them if the 40.100 would be enough.

IrishChamp 04.05.2012 06:34 PM

I emailed Schulz. I'll report back what they say.

Btw, where's this cheap jive 120 you speak of? :)

Not sure how the new ones are built, but the older ones had what it seemed to be a thick copper heat sink in between the PCB. The Schulze L has a larger footprint compared to the Jive. The Jive has a car mode, but I don't think it has reverse. The Schulze L, XL and XXL are all OPTO and you'll need an RX pack or external BEC. Schulze was going to release the M series which was going to have a BEC for their HV units, but they will not be available this year. That cheap Jive 120HV in the other forum is looking good, too bad my 10S ESC is still going strong :lol:.

mothman 04.07.2012 01:13 AM

I always wonder how can the durability/strength be improved by increasing the ball end. Same thing happen to Savage drive shaft. they increase the ball end size from 9mm to 11mm. I think the wall thickness of the drive cups/outputs are just the same?

Look at how the shaft is narrowed at the end where it attaches to the ball on the middle standard CEN cvd. A larger ball has a larger area attaching it to the shaft = more strength.

IrishChamp 04.07.2012 12:37 PM

Hd cvd pin is thicker and the cup is thicker as well, more mass I guess to spread shock over a larger area??
I'd assume cvd's usually fail at the ball and cup area.

wellby 04.07.2012 03:09 PM

How is the shipping from Cen I haven't heard many good things about them as far a getting parts shipped in a timely manor.

IrishChamp 04.07.2012 05:04 PM

Not bad, I think it took a week. They are shipping direct from Taiwan I think it was.

A little info from Schulz:
"Hello,

... sure, in car mode a reverse gear is available.

Note: It is only allowed to use an inrunner motor for boat and car applications.

Best regards
Matthias Schulze"

"Hello,

You are in need for a future-xl-40.160 for 12s
or
a fut-xl-32.202 for 10s.

The future -l series is definitely NOT strong enough, you even should better use a future-xxl type.

Best regards
Matthias Schulze"

IrishChamp 04.21.2012 12:11 AM

I've made a little progress, it's slow going though right now. My busy season is coming up and the new baby is keeping me busy! :)

Made some shock mounts:

IrishChamp 04.22.2012 05:40 PM

What are some opinions on using one of these for the motor? Nice and secure it seems. It also looks like the rcm universal diff/motor mount is back in stock.
Anyone know if the rcm mount will accept m4 motor screws and the 1527 motor?

lutach 04.23.2012 03:02 PM

Can't wait to see your truck in action.

I have 2 motor mounts that I bought that is somewhat like the one in the link, but I think the RC-Monster center mount might be a better option. Make a thread here (http://www.rc-monster.com/forum/forumdisplay.php?f=6) regarding your questions for the center motor mount and I'm sure that Mike will help you make your truck a solid machine.

IrishChamp 04.23.2012 05:09 PM

Ordered the Universal RCM mount.
Mike is modifying it to allow the m4 motor screws.
Thanks Mike!

IrishChamp 04.28.2012 01:00 PM

Just got a tracking #, motor mount is on its way!!

IrishChamp 05.20.2012 03:15 PM

I've been busy, I'm very close to done but I don't have any time!! :)

Lookin' monstrously good man! I've got both a converted Muggy and XXL with oversized wheels/tires which are both indestructable but don't look as beefy as your ride does. What body are you going to cap it off with?

IrishChamp 05.20.2012 10:06 PM

That is an excellent question, :) I haven't decided on a body, Probablly
A Redcat Rampage body or something similar.
I have high hopes that this is a tough rig, we shall see, if I ever get it done.

IrishChamp 08.26.2012 01:03 AM

It's been a while but I finally have a little time and I'm almost done. Just giving it a once over, running the wires, securing and programming electronics etc. I also still need to get a body but it's almost driveable!!
I'll post pictures soon and then some video.

IrishChamp 08.26.2012 03:50 PM

1/16th, 1/10th and the Nemesis XL.

I can't believe I did something so dumb, I managed to apply reverse polarity to the kontronik 120hv while situating everything, the leads just tapped each other for a microsecond. So smoke from the esc or battery, but the esc is flashing the reverse polarity code. Word is kontronic won't fix it and they may or may not offer me any deal worth having. Supposedly it is fixable though by someone with the necessary expertise.
Hopefully I can find someone to repair this paperweight.

IrishChamp 08.29.2012 06:20 PM

More pictures. I'm not loving the body but its not bad, I'd like to find something unique but for now this was easy and looks like it will fit nice. I just have to make body post holes and walah!

IrishChamp 08.30.2012 09:56 PM

My bad luck continues. I installed the kontronik 55-10-32, programmed it, tested it with the motor gear mesh seperated, went out to for a test drive; when I hooked everything up it powered up normal then as I was installing the body te iroytle glitched just a tiny bit and poof, smoke.
Now I have two dead esc's!?!?!!!!
Grrrrrrr.
Anyway, all I have to do is mess with it on the bench so here are a few more pictures with different configurations.

Finally got to drive it, only for a few minutes, right as I was getting ready to take a quick video the steering broke, completely random but an easy fix, no video though. I need to adjust the suspension I think, it felt very unstable under hard acceleration, like the torque was twisting it and making it pull to the side.

RTR Weight w/ big joe tires & 10s 4000mah = exactly 19 lbs. not too bad I think, although its not light when you're carying it around. :)
It will be a lb or so heavier with the gst wheels I think.

Currently geared for 48mph, 55mph w/ tire ballooning.

Motor and esc (schulze 40.160) seemed to stay cool during the limited test.

wellby 09.25.2012 12:22 PM

Funny you say the truck pulls around under power my 6x6 genesis does the same thing my motor is up front and the truck pulls left under power. I have gone through the suspension but it only does it under full power. My truck weighs is at 22 pounds with a 1717 on 6S. Thinking of trying a gryo to stabilize the truck

IrishChamp 09.25.2012 03:51 PM

6x6!?!? Nice
Keep me posted on how the gyro works, interesting idea.
I firmed up the springs a little and in the back yard it seemed a little better.

How's your drivetrain hold up to 22lbs of truck, have you had any issues?
I'm hoping this will be a worry free truck.

Haven't had and driveline issues diffs are nearly indestructible considering I can't get traction:lol:

IrishChamp 09.25.2012 10:40 PM

Very cool!
I shimmed my diffs nice and snug for extra insurance. Do you have any video?

Btw, I sent you a pm.

A couple little clips. Stayed cool, batteries, esc and motor all only got barely warm, guessing 100 degrees
Center diff was the warmest thing I think :) it has the 1,000,000 weight stuff in it, works well at transferring power for about 2 minutes then it gets hot and hello pizza cutters.

Having the same problem with the diff heating up and unloading power to the front. I have 500.000wt in my center diff still not that good. tried locking the diff and I all that happened was I ripped the center diff rear output off.

IrishChamp 09.28.2012 10:34 PM

Just too much truck for a standard sized diff I guess.

Truck is looking killer! I'm surprised to say the big joes fit the truck rather well.

IrishChamp 09.30.2012 11:22 PM

Thanks, I didn't think I'd like them much but the actually work.
