this guys is insane....
 

twin mamba monster on a 1/5 scale...thats what im talking about.

wow, thats a beast- i want to know where he found his money tree at :lol:

I was thinking of buying a kershaw design 1/6 scale revo and I have 3 mamba monsters lying around myself....then pick up some 22.2v 6s lipo pack like two of them and run them.....

i tried it with an e-maxx, but i destroyed the transmission once then a diff and i'm still trying to tweak it to get to run right. i've gotten it to about 70-75 but after that, i start stripping gears. i'm thinking UE or something. here's a pic:

wow dude you rthe insane one :lol:
is that a single motor setup you have?

No theres 2 motors in there...


theres a guy who put dual 1515's in a e-revo somewhere.

those were 2 neu 1515 1y's in that e-maxx. i can pull it off with 2 pole feigaos, but the neus are just soooo much more powerful they just keep eating gears. i don't know enough about the e-maxx to know what manufacturer/ fabricators would be the strongest. maybe UE, maybe FLM...either way, it's gonna be awhile till i try again cause it's expensive to keep replacing.

I bet it was fun though...thinkin of doing my kershaw 1/6th scale revo then now after seeing this one myabe with some hybrid bulks and 1/8 scale diffs.

holy gear noise batman. i would say hes geared very low.

Ue 8 spider diffs would be best for a speed demon emaxx, but not too much you can do to beef up the tranny. FYI though, we have a member here who put a neu 1521 in his erevo and made it do 81-84mph. Single big motor has many advantages, so long as the esc and batts are up to scratch.

This 1/5 truck appeared quite a whiloe ago, but it is still rather impressive.

wouldnt two motors just provide more torque though?

If they were both 1515 sized, then yeah. A pair of XL motors vs a 1521 would be interesting though. I wouldnt get too hung up on torque though, think more about power output in watts probably. John Crook (aka Johny Maxima) only managed 70.1mph with dual 7XLs on 5s lipo, where as the other guy did ~84mph with the 1521 1y on 6s lipo, so dual motors wont always be the best way to achieve insane speeds. The extra weight of dual motors and batts would weigh the truck down alot, and the dual motors turning a single spur could lead to potential stripping issues.

Hmm, E-Maxx is not 1/5 scale, even with longer chassis (they call it 1/10, don't they?). And why make titanium driveshafts, steel is stronger.

i thought about a 1521, i'd love to try one, but aren't the mounting holes spaced differently so you'd have to fabricate your own mount?

just wait for my LST............ muah hahahahaahahaha:gasp:

Nope, all the 15xx series motors have standard 25mm mounting patterns so far as I know- it'll say on the Neu website:

Yep, thought it was.

Cant remember if the guy used a 1y or 1.5d, think it was the latter- the thread is around here somewhere...

found it. 'Twas the 1900kv 1.5d motor- the vid is just nuts, you need a runway to test a truck like that :yipi: :yes:

this is an awesome video..

Wow, that truck literally tears up the grass!

now that was badass lol...a big 1/5 scale truck on brushless....oh boy

Wicked.

We have been waiting.... For a while.

A 1521 is a great motor for a heavier monster truck. I run one in my muggy, and plan to give it a try in the 6x6 lst as well. I will gear it a bit lower in that truck, say 35-37mph. It is a 1y - 1577 kv, so a great 6s motor. I also have 1521 2y and 2.5y motors, 10-12s in those (with the right controller).

Willing to sell that 1521 1Y in the future?

that truck moves like i would expect an 1/8th scale to move. much more torque than a gas engine.

Not likely... I have 2 of them as well, but I have a feeling they will both be put to use, and i may buy more. I want to compare the cc/neu (I have a few of those too) to the 1521, both on 6s, and see if the higher rpm and lower gearing makes up for the shorter rotor. I have a feeling the 1521 will produce better temps, but we will see.

That truck is one of the most awesome brushless vehicles I've seen. Its also the inspiration for my 1/5 revo, cause I can't afford the electronics required for something that heavy. But I love the large scale and the power.
