50mph B emaxx

[luvsrc]

Today I have the time to play with my 6s Lipo max amps 8000mah with my wanderer 12 XL put my EPA in my Mx3 transmitter to 140% throttle and my bobmproof emaxx hit 51.20 mph on a large parking lot using a 23mm proline badlands with duct tape inside to prevent it from ballooning ,next time i will post a video :018:

Sick!

Pics please, I would like to get some ideas for mounting lipos on my bombproof chassis.

Sure man I will post it once i got home tonight

Wow, very fast. Didn't know the 12xl can hit such high speeds even if it was on 6s.

6s Lipo 8000mah- how many volts is that exactly / Kv rating of the 12XL?
I want to see the pics/video too, Im really starting to get excited about running my truck properly for the first time....

with proper gearing and putting my EPA throttle to 140% makes a big difference.Here is some pics

[luvsrc]

6s lipo = 22.2 volts but actually it is more than that more like about 24 volts on full charge

[luvsrc]

1390rpm/volt is the rating for the wanderer 12 XL , so 33,360 RPM on 24 volts

At full throttle the cells might drop down to about 3.4-3.5v, which is 20.4-21v.

what is point of adjusting the throttle EPA to 140%? thx

He just set his epa all the way to make sure he was hitting full throttle. he probably normally has the epa turned down to make the truck more controllable.

I discovered interesting on EPA at 100% it spins like a 12XL should spin on 6s lipo but put it all the way to 140%,it spins very fast a lot faster than 100% like a turbo boost ,can someone explain this?

[suicideneil]

It puzzles me somewhat that a motor rated at about 4000KV & 14.4v will spin at upwards of 40,000 rpm, yet a motor rated for 2000KV & 24v will only spin at about 30,000rpm- but its much more powerful & moves truck faster..... The difference in torque is the key obviously- a 'slower' motor will run a truck faster because its a longer can, and the # of turns affects it too- more turns equals more torque+less current draw I think? Its all somwwhat bewildering but I think Im getting the hang of it now....

well, the novak hv-maxx may spin fast, but it is geared around 22/1 i think.
while a 30k rpm xl spins slower but is geared like 15/1 or so.
that means the truck can go faster.
take a peek with brian's calculator.

I read it like he upped the throlle EPA above the programmed 100%. Anyone else have experience with this?
