Maddness

I like to see it in action. It is one massive motor though.
It is going to have massive power as well. If you get it
right it will be awesome.

[nieles]

what kind of esc are you going to use?

40.160 probably.

5th chassis sounds a lil better, more room.

Interesting project, Darren. No problem to make the motor mount, either. Just send me a file/drawing of wht you need.
If you want to get to this speed record, get to it - I recently built a 40 cell electric maxx type for a german Vendor with a direct drive center diff(8 spider) and a 3/8" thick motor mount for a "22" series motor(they too hope to get speeds bordering on INSANE), though keeping these beasts on the ground above 60 or so will be pretty tricky! The truck I built was designed and geared for speed - every 500 rpms yields 1 mph, not accounting for tire ballooning(using a 15t pinion - larger pinion would yield yet more speed). Batteries will be the biggest factor for these heavy beasts(the one I built was LARGE - the customer wanted a MONSTER so it has a 16.5" wheelbase and 7+" tall tires).

possible esc's would be: Schulze 40160 or bk will bring out a new 250 amp esc. desgined for the lehner 30' series this year...


A fg marder would never have a chance against a 3080 (perhaps on 12 cells:025: ) i have seen a powerboot with 2 lehner 3060 on about 220 cells this was awesome, the air smells like power;)
But we are not talking about boats! a 3080 has a very high resistance because of its large rotor so when the car starts running the esc and batts would get too hot.

To build up a 1:6 car with such a motor could be doable, but a 3040 would more than oversized!! The Motor in this case isn't the limiting factor of power, the room and physik make the limits...
I have already the idea to convert a 1:6 car to a muscle car. So i had told to a friend who build up 1:6 cars since many years about my idea and he said that you need a 4WD car do get the power on the ground. A big problem is the immense torque of a 3080... A FG marder wouldn't have a chance, no way!

Remember, its not an everyday car, more of a drag.

That's clear... the challenge isn't to build up a car that runs very good on a track (this would be really impossible) but to get a car which can handle the power. For a large motor you can modified every car but for a monster like the 3080 you need a complete selfmade car which is constructed for THIS motor. The car need to be balanced out very good, the centre of gravity must be in the right rate, you need a good steering and a trained pilot, a bullet proof transmission... all parts must be machined very precisely to minimate vibrations and friction
->heat->wear...
too much dirt or vibrations will kill the motor!! Remember the motor is originally build for boats.

The "traditional" way of transmission with spurgear+pinion has in this case no chance too, every pinion will be to weak (in powerboats you haven't any transmission, you only have the motor and a long driveshaft to the "propeller"..)
You could put the motor directly to diffs but they also will not stand the power...


And imagine how much great cars you could build up with the money (perhaps 8000-10000$) you spend for this one.


Just my 2Cents...

I wish you much fun with this project and a n1 result:027:

I recently built a 40 cell electric maxx type

pics?:004:

[RC-Monster Mike]

I have a couple of pictures of it mostly complete.

[RC-Monster Mike]

The wheel/tire it is resting on is a standard maxx bowtie on a velocity rim, so you can get an idea of the size. It is a custom chassis based on the FLM, but stretched to hold 10 cells per side on top and/or bottom and an extra attachment point for the braces. It can hold up to 40 3700/3800 sized cells and fits Maxx parts to it(has hybrid bulks, 3 8 spider diffs, etc. for strength). The rear of the motor will be supported along with the front at the mount. It should be race/track worthy with a sane power system, despite its huge size. :)

:004: :004: n1 work dude!!!

40 cells yeah this i call overpowered ;)

I think you said it allready the batts are the problem. Lipos for this truck would simply rock but i don't want to think about the money for this lipos...


So keep us uptodate with the truck...


You said for a german vendor, hmm i'm thinking and thinking who could order this truck:010: ....

[neweuser]

that thing is insane! even without the motor and batteries! Great custom work Mike!

[RC-Monster Mike]

The truck is already in the hands of the owner. Silly me didn't think to take any pictures of the beast in completed form! She is a beast, though.

[neweuser]

I bet. No pics of a completed project? Talk about teaser!

The general concensus here is that im gonnna have to sink alot of money into this. While I don't believe this to be true, the project is seeming distant.


I guess i'll have to wait and see how many hiccups this supemaxx gives me first.

[squeeforever]

Mike, are those the 55 Series tires like on the CEN truck, if I'm not mistaken.

[RC-Monster Mike]

Yep. Nemesis tires from CEN Racing.
