HV-Maxx 4.5 or MM and 9xl?
 
Cant decide what setup? I want somthing that has more runtime and power the the titans. I have 7 cell IB4200 WCE batteries and it makes my truck do about 35 m.p.h. So Im staying with the 2 speed, and something that I wont snap my axles. I not sure If I should go to BL. O and also will I be able to program the esc? Like the threw the USB?




What would I need for this? Im going to get >>

List
-------

3.3 revo axles and centers
3.3 revo knuckles
3.3 t-maxx 3.3 turnbuckles


I need to get
---------------

FLM diff cups (x2) $60
Integy Aluminum diff case (x2) $50
Hardened steel idler gear-Emaxx transmission $28
Integy Gear Box Collar (x2) $10
-------------------------------------------------------
$148 ouch! plus the motor!

I would take a mm and a 9XL over the novak any time a day..

Without a single doubt; it's a cheaper setup, which delivers more power. You can program it by computer;

you need a separate UBEC though.

I definately Agree.. that Mamba Maxx ESC is the best bang for the buck! no doubt.!

Well Lets say If something would happen to it like it fries what do I do then? Do I just put the 3mm connectors back on a exchange it? So What gearing should I be using for this setup? On 14 cells. Does any one have videos of this setup with 12 or 14 cells? Or just pics? Also what about runtime?


Im going to the 3.3 axles so what do I need?

3.3 revo axles and center
3.3 revo/t-maxx knuckles
3.3 t-maxx turnbuckles

On the revo center one side has like two screws sticking out of it. DO I have to cut those off?

I take it you mean the centre sliders- I would get some proper metal CVDs- much much stronger. The rest of your list is fine.
The MM wont take 14 cells very well.

I would run the 8xl on the MM with 12 cells. Gearing wise...... start at something like 25:1 overall, then maybe go up on the pinion a tooth at a time/ down on the spur a couple teeth until you find the 'sweet spot' for that setup.

E-Maxx King 05.26.2007 06:42 PM

Well with a ubec. Well I only have $80 for the axles so what? Will thede axles hold the stock titans on 14 cells? In tell I buy the BL? How long will the axles last on the titans?

way off.
remember that's its not a high rpm motor, you can start gearing a 8XL around 16/1, it'll do about 30ish then.

Yeah I do my 8XL/MM right around 16:1

Great amt of TQ and speed on 4S. I consistently radared ~41 mph on 14 GP3300s. Great combo IMO.

suicideneil 05.27.2007 07:28 PM

Wowzers, didnt realise you could gear them that high, its a big leap from the HvMaxx gearing of 25:1 on 4400kv, guess I have to start learning all my ratios again if I went the XL type motor route.
$137 for the MM + $80 for an 8XL + $34 for XL clamp + a few more $ for pinons and gold plugs etc.... = ~$280ish/£140. I'd call that a bargain for what you're getting- I think I have found my ideal setup... now to finish saving up £££ (donations welcome).

BrianG 05.27.2007 08:53 PM

Well, the HV being rated for 4400kv is pretty hot. So, you'd need to gear that down appropriately. Plus, an XL motor has more surface area and bigger section for windings, so it's probably more like an L motor. The rules haven't changed really.

coolhandcountry 05.27.2007 10:05 PM

I would shot for stock gearing and go from there. 18:1 is stock and the
motor turns more rpm than stock. Bingo faster and more power with same gearing. :D

E-Maxx King 05.27.2007 11:08 PM

Is that with the 9xl? What runtimes could I get? 4200 7 cells. Cause I get about 30-40 on the stock setup.(I not going full throttle the whole time)

E-Maxx King 05.28.2007 02:16 PM

I just read some stories from bp-revo and someomne else. One said his 4.5 beat a 8xl and mm and the other he kept up with a 7xl. I like the 4.5 or 6.5 cause I drive ay low speeds so there wont be any cogging. And another is cause Ill have a warranty on it I think.

Serum 05.28.2007 02:25 PM

an 8XL will simple have more torque/power. perhaps he had better grip with his tires or his truck was lighter.. or the 8XL user had poor batteries.

E-Maxx King 05.28.2007 03:45 PM

K how would these come out?
