BL E-zilla , BK 7020/9L possible?
 

Hello,

I own an HB E-zilla and I want to go brushless...

It is stock with 13cm diameter tires, 66T spur and 20T pinion (1/8 shaft), weights 4.3 kg.

Will work this set-up?: BK 7020 (only 70 Amps) and a Feigao 9L.

The batteries are LRP 3.000mA 6 Paks and LRP 3.300mA 7 cells packs.

I have a motor heatsink/fan . Should I install a ESC fan, too?

regards.

I forget,,,

Gear ratio is 16.75:1 with the stock 20T pinion.

Welcome to the forum there vwt4.
I would not run this setup. The 9l is fine but I am pretty sure you going to have thermal problems with esc. If you do I would definitely put the fan on esc. You going to have to change the gear ratio as well.

Do you think a 19,71:1 gear ratio (with 17t pinion)would be better?
And a 9XL?

thnks.

That would be better for sure. what speed do you wish to reach?

50km/h would be great!

Then a near 20:1 ratio and a 9XL is a good idea?

With the gearing you have got in mind, it would do 55 km/h.. I would use a 9920 anyway. the XL series can take some serious power for sure.

Is there much of a diference between a savage chassis & a Ezilla chassis ?. Besides all the nitro stuff.

yeah, i don't like the e-zilla...

No, serious, they are rather alike. not the same, they just look alike

Both wears TVPs but the E-zilla is a little smaller.

So would it be better to convert a savage oe use the Ezilla chassis ?.

savage is proven tough and has got more nice hopups available!

Yes, but the E-zilla is in the beginning...

In a few months will be lots of afftermarket parts.

The e-zilla is 1/10 scale though,i think the stock tyres are more like 2.2" sized?

I'd like to know what the diffs are like on this truck.

In this link:http://www.rcuniverse.com/forum/m_30..._2/key_/tm.htm ,if you scroll down to a pic of it next to what looks like a lightning GT you can see how small it is.I'm not sure i'd want to put an XL motor in it.

I don't like it in general, it's just a cheap ripoff imo, and it is alot like the conversions we did in the beginning with our savage, i don't like the battery packs sticking out under that angle, like they do..
it just doesn't tinker my bells..

a 9xl would be better on the 7020 than the 9l would. I have run this combo with sucess.

Not on 20 cells i thought?

I will run 12 and 14 cells with the 9XL.

Is it a good setup?

You are right serum. I have not tried on 20 cells. I have run it in my mgt on 14 cells with a full run on the batts the esc will get up to 110. I was going to try 18 but would not fit on the truck.

with 14 cells you should be in the safe zone.

hi
the e zilla has smaller diffs that look like those of the hpi mt2. the gears in the center gearbox look very much like the e maxx stock. i have seen pictures of the open diff and the open gear box.
i would definitely not propose a XL feigao to put in the stock e zilla. i do not own one but i am pretty sure it will not hold up long.
i think your first proposal with the 9L would be much more of an appropriate setup. the 9L is rated with rated at 68A. on accelaration it might easily be more. so with the 7020 you might be very much on the limit. a 9920 would be safer so to say. then maybe you could also think about a 8L.
with 12-14 cells that sounds not bad to me as the e zilla is pretty lightweight.
it is difficult to say what hopups are coming for the e zilla.
as for the savage you can read much here in the forum.

I thought it had planetery diffs,can you remember where you saw those pics?

In that pic i posted i think the tyres next to it are probably the 8" GTX2 tyres,so maybe it's not much smaller than an e-maxx.

I agree with rhylsadar 100%. I've seen the zilla in person. A 9l and 9920 on 12 cells would be fine. I think it has plastic shafts so it probably wouldnt hold up to an XL anyway.

If that is the case the 9xl will destroy the driveline then. I have doubts if it will hold a 9l. I guess what ever you put in the truck let us know if it holds up.

The planetary is in the main gearbox the f/r diffs are gear type and look weak. without mods to the TVP's you won't fit anything bigger than S fegaio in truck

not sure but if you could figure something out to fit a L can you might want to consider a 10l.

Somebody on another forum fit an L size without any mods, said it was a tight fit, but it fit nonetheless.

I'm also with Serum on this one, I just don't like the truck, it seems like it's a rip-off from the Savage (although they are the same company) and is lower quality.

The L series fit perfect, are 61mm long vs 63mm stock 550 motor.

hi
if it is allowed i post a link to another forum. you can scroll down and see the pics of diffs and gearbox.

Ok. I stand corrected. I was going by another thread on this forum where someone tryed a novak system

I have an 8L in my E-Zilla, with stock gearing and E-Maxx size tires. As for ESC, I have tried MGM 12012 and Mtroniks Truck. Yes, heat sink and fan for the motor are recommend, but nothing go up in smoke yet. My E-Zilla is ~ 9.5 lbs with 12 NiMH cells. With the stock tires, it should be ~ 9 lbs.

I think with 9L/12 cells/stock tires, the top speed should be ~ 50 km/hr.

Here are pictures from my BL E-zilla with 9920 and 9L.

It runs great!!

no issues so far with the center shafts?

that is a UBEC right; how do you like it, because i bought one and havent used it yet?

justin

The UBEC is a little more expensive than a 5 cells pack for the BEC but it is lighter and you dont have to charge it.

Here are a few videos, indoor bashing a rainy day:

How strong is the ezilla?

It is a very fast monster, and light weighted. You need to cut a little the plastic to ware 7 cells batteries.

By the moment the transmission is OK with the BL setup.

There are not option parts in the market, maybe next month....
