MAX Continuous Current on MMM?

[BL_RV0]

Ok. I think I got my setup figured out.
Motor: Neu 1521 1.5d
ESC: MMM
Batteries: 2x 3s 4500mAh 30c FlightPower
Center Diff: HB Lightning
Diffs: E-maxx 3905 (for now)
Gearing: 10/50
Tires: mashers, mulchers, something 40 series
Wheels: something 40 series and 23mm
Axles: center dogbones, ft/rr: stock 3905
Chassis: FLM

What do you all think of that?

Here you go.......its beside an 8XL

[jzemaxx]

One more....



With the truck strapped and lowered fastest GPS and radar pass was 74.1 mph. Tried a few more times, but the truck kept going airborne....so that is all for now. The 1521 still has ALOT more left in it......its barely breaking 110 temps. All runs were done on 8S. I can go 10S, but it was useless as the truck just hazes the tires hard around 60mph when you roll into the last 1/4 of the throttle.

Have you tried mounting a wing to the front to keep the nose down? From the front lifting and the tire hazing at high speeds, sounds like you just need more traction...

[jzemaxx]

I ziptied a 1 1/16" heavy impact socket on the front and it helped some, but I'm going to try some heavier weight next time. I haven't tried a wing yet, but I am working on trying to come up with one. Problem is drag will go up exponentially then, but I guess I will just more up to higher voltage to compensate.

[BrianG]

How about just using a Proline wing in the front on some custom mount? But yeah, drag will go up.

The right body, body scissors, a knife, and a heat gun and you could rig up some good down force. I did this with my stock pede body and eliminated a lot of lift. You also want to be concerned about the rear at the same time because rear lift can cause the front to get squirrely and lift as well. If you are using a truck body, simply cutting out the tailgate section does wonders. Sometimes it just takes experimenting with different things.

You are right....my high speed XTM BL MT has the rear cut out and handles ALOT better at higher speeds now. Also a longer wheelbase does wonders. I can run 10S on the XTM truck and it will NOT lift off....just hazes the tires. Awesome BL truck.....I don't think my emaxx will ever be to the level of it, but I'm working on it.

jz, what do u use for brakes on that emaxx? The HV110 doesn't have brakes, does it?

No brakes per say like conventional ESC's but it does have a brake. I used castle link to put the brakes on 10% with zero delay and I just use them when needed. Very nice mild braking. When I don't want it to brake I just keep my finger barely on the trigger to de-activate the braking. Only with castle link you can change it to 10%. Manual programming only offers, no brake, 50% brake or 100% brake. 50% brake sends the truck flipping end over end....lol

Got pics by chance of your setup?

[TexasSP]

No, the pede is sold now. I lost interest in it and never got any pics with the body on after I changed it.

Trimming down the front end area, down the sides, and around the wheel wells was the start. For the heat gun part you heat up the area about 1/2 inch shy of the base of the windshield and cut down the length, then using the heat gun (or hairdryer) and a block of wood or something similar, mold the body up to allow air to flow out.

Anyway, I think trimming the sides and front down some front and cutting the rear tailgate out yielded the most improvement.

I will also say that on the MM (which should be the same for the MMM) adjusting the punch control and throttle curve did a lot to help keep the front end from lifting as well.

Jze.. what kind of amps are you pulling with that 1527....?

[jzemaxx]

Haven't ran the 1527 yet, so have no idea.
