Best brushless for 10.5lb. E-Maxx
 

Well I just finished puting together my second maxx from all of the extra e-maxx parts I had. I was driving it around yesterday and just couldnt get excited about it. Maybe its because I'm used to the power of my other maxx with the dual 9Ls (gee, you think?)
So I'm thinking a brushless (single) system is in order. I'm just not sure what to put in it.

I lightened this one up a bit and it weighs in at 10.5lbs RTR with 14 cells. I don't race, mainly just drive in front of my house and the occasional bash session every once and a while.

I thought about just going basic and getting the HV Maxx setup but I think I may want something a little bit faster than that. And No, I am not going to use one of my 2 9Ls either. :D


Any suggestions?

Thanks.
John

EDIT: Preferably a Feigao because of price.

How about a 7XL/9920? That seems to be a pretty popular setup around here...

Thanks MetalMan.
How does this setup differ from my 9L/9918 setup?

get a 9l c540!! lol!! This must cost alot for a 2nd e-maxx. How aboutu sell me one of them brushless system or just the esc?

The 7Xl is more powerful, but the 9L has about 400kv higher. Many say that the 7XL can be geared to match the speed of the 9L, and still have more torque (on the same number of cells). But the 7XL will run even better on 16 cells!

more cells, more weight!

What are you looking for john? Long run times good power or a combo of both. I don't think you would be happy with the hv maxx. What kind of speed you trying to get as well? The 7xl is a decent system. 14 cells it would move your emaxx around pretty good.

LOL!:L: Wait, didn't we allready have this conversation?:rolleyes:

I think I will be leaning more towards more power coolhand. I usually break something before my batts run out anyway. As long as it does at least 40mph, i'll be happy with that. I still plan on going LiPo with both trucks in the future.

So to put it in terms that I can understand, the 7XL has more horsepower and the 9L has more torque?

accually the 7xl has more torque as well. How many lipo cells you going to run. run a 36 95 with a 9xl would really rock especially on a 6-8s.

Johnny my gmaxx weighs 10.5, i use a Lehner 3100xl; on only 12 cells. I can run down some truggy's with it its a awsome motor you might want to check it out:D .

yup. i got the same motor. it will far exceed you speed expectations. it leaves my nitro revo in the dust!

The 3100, is it this one you are talking about?
So for me running 14cells would I run this one?

yes. the 3100xl would run hot on 14 cells so i would step down to the 2800xl

So now I guess my question would be, is the XL2800 worth the extra $60 over the 7xl? Am I going to notice a big difference in speed?
Thanks

im not sure about that but i have been told that the 7xl can be geared to run with it and still have more torque.

What about the weight issue?

what about the weight? if geared right that weight wont be a problem for a basic xl, if thats what you mean.

No maxxima;

That basic XL really is no good for you.
You like it more powerfull, eversice you've got this dual setup. the 7XL is the mininum i would take. or you are planning on running a high voltage setup.. you can achieve good results with a basic XL, but it's not what you expect from a BL setup, you are used to DUAL motors that are more powerfull each than a basic XL

I got an idea john. Take one system of your other truck. I know you don't want to. Put it on the other truck and run it to see what you want. It give you an idea of more of less. If you know what I mean. That away you know about what you want out of the truck. Then order up what you want and put the 9l system back to the duallie.

O.K.
After all that, I found a used 9L on ebay that I won for $62 (includes shipping). He said he only had 2 runs on it (yah right). Still $20+ cheaper than a new one.
Now I need to get a controller. What is the difference between the 9918 that I have now and the 9920?

same thing, i think the 9920 has the ubec. WHy do you ask??? u foudn a used one?!?!?

I'mmmm not tellllllliiiinnnn!!!:D

a 9920 is the same thing as a 9918 except they changed something with the built-in bec. they say it works better now on lower cell counts.

The 9920 is slightly upgraded. It has dual wires everywhere, the throttle curve was adjusted, and it has been more optimized for lower cell counts. It still has the same BEC chip as the 9920, though.

O.K. thanks!

What he said! Except they don't necessarily have dual wires everywhere. Most still have single wires(nice, thick wires). The 120 amp and above have dual wires. Some of the 9920s came with dual wires, but most don't.

Now if you could just get those dang things in stock, the world would be a nicer place.:D
