Put those two setups on equal voltages please.

This outrunner will make about 900 watts, so I'm thinking the acceleration should be there.

Another option would be to go with the 2826/8 motor. It's a higher kv at 1130kv.

The mod 1 gears are alot tougher than the 32 pitch gears aren't they?

Mod1 is quite a bit stronger, the 36 tooth would help. I only had the voltage set on 14 cells to try and figure out the titans kv. Traxxas claims 35 mph so I figured I would run the numbers. $s will actually hold its voltage arounf the 14.8 mark unless the lipos are crappy! Are you set on 4s or could you go higher, 6s would be killer and allow you to gear down some, which seems to help regardless of the motor type.

Not sure if you noticed, but the chassis braces are set wider on the new emaxx than the old one. Maybe a direct to diff setup would fit? An idea?!

I plan on using the Quark, so 6S is an option. Motor temps are going to determine if 5S or 6S will be the "settling" point.

Here's the 2826/8 wind on 4S with a 36 tooth spur
Differential Ratio: 2.84
Transmission Ratio: 1.83
Other Ratio: 1
Spur Tooth Count: 36
Pinion Tooth Count: 25
Total Voltage: 14.8
Motor KV: 1130
Tire Diameter (inches): 5.75
Tire Ballooning (inches): 0
Motor Current Draw: 0
Motor coil Ω: 0
Spur/Pinion Ratio: 1.44 : 1
Total Ratio: 7.48397 : 1
Tire Circumference (inches): 18.06 inches (458.83mm)
Total Motor Speed: 16724 RPM
Vehicle Speed: 38.23 MPH (61.4km/h)
Effective Speed Rate: 2.58mph/V (4.15kmh/V)
Effective KV Value: 1130

Here's the 2826/10 on 6S with the 40 tooth spur
Differential Ratio: 2.84
Transmission Ratio: 1.83
Other Ratio: 1
Spur Tooth Count: 40
Pinion Tooth Count: 25
Total Voltage: 22.2
Motor KV: 920
Tire Diameter (inches): 5.75
Tire Ballooning (inches): 0
Motor Current Draw: 0
Motor coil Ω: 0
Spur/Pinion Ratio: 1.6 : 1
Total Ratio: 8.31552 : 1
Tire Circumference (inches): 18.06 inches (458.83mm)
Total Motor Speed: 20424 RPM
Vehicle Speed: 42.02 MPH (67.49km/h)
Effective Speed Rate: 1.89mph/V (3.04kmh/V)
Effective KV Value: 920

I think it would kick Arse!

Sounds like a good setup, either way. My Emaxx will stay stock until I can finish the other conversions I have sitting around. Going to convert a Losi aftershock and use an 1100kv kb45 inrunner on 9s lipo thru a hv85 esc. Stock tranny and 2 speed so it should be plenty fast!

Just go Play · 12.23.2007, 03:47 AM

My bank account is so envious of you unmarried guys. I can't wait to see what type of monster you turn the new ride into!

nl12 · 12.23.2007, 11:15 AM

see if the transmission will fit on the old version

YES.. it's plenty fast.. I'm running the 1000KV on 12S 3700mAh Lipos on my LST...... and it's super duper fast... but snow is melting fast.... I will get videos on a nice day...

8S1P 5000mAh 25C Lipo & 1800kV KB45 on MGT, and 8S1P 5000mAh 25C Lipo & 1000kv KB45 on GST 7.7...

Those KB45 are just great motors for the price... just gettin' the pinions sucks monkey butt... but thank God I got myself a lathe...

Good to know aqwut, any chance you could shoot a few pics of your lst so that I can see how you did it? Also what esc are you using in the lst and your 15l powered t maxx?

OH, and I am married guys, just buy what I want anyway. I made sure that the wife knew that about me before we got married.

I hope you mean 6S A123 or NIMH cells? the quark isn't capable of 6S. I need to come across the first who uses 6S lipo packs in his truck with the Quark without killing it.

Will you put a BL system in it? This may work: Motor ESC 30 of them

An E-Baja 5b SS is my absolute dream project

The new style Transmission mounts different. It mounts to the underside of the chassis instead of going through the frame rails. 4 Bolts is all it has compared to 8 mounting bolts with the old style.

If you want to upgrade an older maxx, get the Chassis and the frame rails to go with the transmission.

I have ran 6S Lipo through my Quark 80 probably 8 or 10 times. I did notice improvement running 6S after doing the Cap mods.

In the E Revo, the new Quark 125 amp ESC did pretty good on 6S. I added one of the Novak Caps to it's power lead. Temps weren't bad at all and it was hauling Arse!

I wonder if the Quarks that died were from lack of additional heat sink? Or perhaps FET/heat sink separation that's been discussed in earlier threads?

Got pics? I wonder if the width of the new mounting points is okay, and it just requires 4 new holes drilled onto the chassis (mount it ontop, rather than underslung).....

Ok Neil, here ya go partner.

Check out the pics. You can see the 4 tranny mount bolt there on the underside of the chassis. Bolts are 41mm x 52mm center to center.
