Hi guys!

I have become interested in building an 2.2 MOA comp truck. Just so you know I am not going to buy one for a while $$$ is tight at the moment.

But I would like to start gathering info and ideas. I have heard alot of good about berg and bully axles are there any other worthy choices out there? If so which are the best for comp builds?

kasper · 10-08-2009, 02:23 PM

I like my berg i also have a losi comp crawler with the eritex moa kit its not a bad setup but its not a berg.

Col. Sanders · 10-08-2009, 02:34 PM

So you would say the berg is better? Is that just because it's stronger? Or are there other reasons?

fa1rch1ld · 10-08-2009, 03:06 PM

There are other reasons.. Everyone prefers something different. Do you want

Aluminum? Plastic? Heavy? Light?.... I run a Losi MOA. I have NO stall now that I

have fixed it and never break. The axles are worm gears, which means instant

brake on hills without a drag brake ESC. Also they are PLASTIC + High

Clearance = Slides smooth on rocks. But its all preference... I run my Rig around

5lbs with the MOA setup with the Leopards. It climbs better than any rig I have

seen. You will find people that swear berg, and people swear by Losi.

I will say though now that I have gone from a Losi Shafty to the Losi MOA....

I would never go back to a shafty.

kasper · 10-08-2009, 03:23 PM

Please dont take it the wrong way i do like the losi moa its a great crawlerand its getting better the more i dial it in may i ask how you got rid of the clod stall in your losi yes everyone has there prefrences the losi is a nice rig you wont be dis appointed if thats the route you choose.

I've had good results with my Bullys. They are built right out of the box....no need for any upgrades.

I'm running a simple setup. FXR, punk dig, HH puller 500. I made sure that all

my weiring was the same length from dig to both motors...Helped out a lot.

When I originally had the stall I couldn't figure out what was the problem. So

I swapped the motor from front to rear, by doing this I found out that the

motor was causing the stall. It worked but not to its full potential it seemed.

Got a new motor and it almost completely took the stall away. After that I

changed the rear pinion to an 8 and kept the front at a 9. I now have no

stall.. I cant believe what this thing will crawl up and go threw.. And it

doesn't matter if you use 12 or 14 gage wire. I'm using 14 gage on everything

and it works great. Some people say they switched to 12 gage and it took

stall away... but I don't think it has anything to do with that.

The Bully's have HUGE axle shafts in them? There like unbreakable...What

are they like 4mm-6mm thick or something?

Col. Sanders · 10-08-2009, 04:16 PM

4-6mm shafts sound tasty! so what exactly is clod stall? I have hardly done any research on MOA and all the terms that come with them.

how heavy are Losi axles with the MOA kits compared to bergs or bullys?

fa1rch1ld · 10-08-2009, 04:24 PM

Clod stall is when one of your motors will cut out when it gets in a bind. For

instance when climbing something vertical the rear would stall out because of

the force on the rear. It can get annoying if it is extensive and cuts out to

much. This is what my Losi was like before i fixed it, now I have minimal to

non. But every MOA has a little stall to it. And you will find that in most cases

its a benefit when crawling. When I get in a bad bind in my rear when going

threw a gap the rear will stall and the front will dig it out. It has saved me a

million of times from getting sucked into a rock crack.

joesbruiser · 10-08-2009, 04:31 PM

I love my berg.
They are tough stock and should be even tougher when combined with the Super300m CVD's

I have been running the same axles for over a year with only 2 small #3 failures and a few wore out shafts.And I run alot .To put it in perspective I have had a 4PK for 2 weeks and it shows over 20 hours and we have had rain almost everyday sence I recived it.If it was good weather I would say it would have 40hours on it.
I beat the crap out of my berg axles and they just keep asking for more.

fa1rch1ld · 10-08-2009, 04:47 PM

And that is why they are so popular

Its like buying a Japanese car over American

Col. Sanders · 10-08-2009, 05:15 PM

Hahahaha!

Just to make sure I got this right, Clod stall is when a motor cuts out and stops turning? Why does this happen?

fa1rch1ld · 10-08-2009, 05:58 PM

Its sending the power to the motor that has less binding. So if you have your

rear stuck under a rock its going to send the power to the front. That is why

if you get your stall to non to very minimal this is were it is a benefit... If you

had a shafty and your rear was wedged into a rock what would happen?

Everything is spinning the same, most likely you will get sunk into the rock

more, or it will flip ya on your back. The MOA and the stall, the rear would

give out and the front would do most of the work. You are more likely to get

out of situations like that with a MOA, that is why they are awesome.... Losi,

berg, or bully.

Col. Sanders · 10-08-2009, 09:27 PM

So is Clod stall a setting on the ESC?

fa1rch1ld · 10-08-2009, 10:34 PM

No. Its not a setting. It just what happens to the rig under binding.

I'm not very good at explaining stuff...Maybe someone can step in and

explain the stall better than I can.

oldhippie · 10-09-2009, 08:24 AM

It really is all about "the path of least resistance". If the front is easier for the motor to turn, it will. There is no mechanical connection between the front and rear (like the drive shaft on a shafty) on a MOA so the axle with the least resistance will turn before the one with more resistance. This can really only be overcome by running dual escs with mixing % control like with a 4pk or manually with a stick radio. Short throttle bursts can help too. But clod stall is nothing compared to the advantages of an MOA.

Col. Sanders · 10-09-2009, 11:28 AM

so clod stall is almost like having a center diff? with out it being there...

landon4 · 10-09-2009, 04:09 PM

It is kind of like an open diff in a 1:1 truck if your stuck in the mud the tire that is stuck won't spin but the other tire will spin.

Col. Sanders · 10-10-2009, 12:31 PM

alright. So how are you guys setting up your electronics? And what parts are you using that shaftys don't use? (electronic parts)
