The 2 red wires im a bit worried. I dont think that my charger will understand how many cells there are... How can I measure? I dont have any electric devices which I could measure it

Woah almost 2 years have been gone since my last post here. Dang time travels way too fast

Anyway I still own this "combination fridge" unfortunately, it haven't gone anywhere.
Im out of projects now and I decided to take this baby to finish line. Any chances? Maybe few skills has improved during this time, I hope. Thanks to this amazing forum

Ok, now to the point. The truck is at the same condition what it was few years ago.. Tons of aluminium, poorly mounted motor and battery trays otherwice its stock. 3rd speed gearbox and so on..

I got it running, but very poorly success. It ate the 60$ pinion, which I purchased from finedesign. I dont think it was all the cause of the bad motor mounting, but the pinion was also very bad.

I have thought putting emaxx tranny in there and toss the 3rd speed for fishnets weight.. Emaxx tranny because it would be a lot easier to gear, easier to mount the motor, saves weight, what else... saves space.

What do you guys think, is this even possible? I haven't yet measure the space for emaxx tranny, but I think it will fit. Have to do somekind of tranny holder for the side plates.

Anything else? Thats about it, O did I mentioned that the truck weights around 22lbs

Sry for my articulation, im still learning

If you figure out how to do the emaxx transmission, lets talk. I need some more speed and this trans is maxxed out on gearing.

I'd do something different!

I'm thinking an RCM centre diff mount or two of your choice mounted between the TVP's with a buggy diff... Should be easy enough to create plates to hold the diff mount...

That gets rid of the brake setup - the two speed and the ugly motor mount.

It should also give you plenty of room to move the battery inside the TVP...

Sure do. This is all in theoretical level still. Have to think other options too..

Not sure if I understood correctly. You mean two of these rcm motor/diff mount thingies and centre diff between them? Does it work?
Thats funny cause I have thought the same thing. But wasn't really sure about it.. Practically this? http://www.rc-monster.com/proddetail...d=RCMLosiMount

Arct1k · 02.25.2009, 07:06 PM

It could It is going to require some work - But yes I'm suggesting a couple of rcm motor mount supenseded between the TVPs to give you a centre diff setup...

_paralyzed_ · 02.25.2009, 09:54 PM

a plate on the motor mount plate in place of the motor and mount with any buggy diff attached to it and aluminum angle for a motor mount. Trannies over complicate brushless setups. The torgue negates any need for multiple gears.

Hardstyle · 02.26.2009, 12:36 PM

Thanks for the inputs
Center diff would be very nice, no doupt about it.. And it would be rather easy to fit in there. Are the mounts how wide? Just wondering that if I mount them between the tvps it would screw the drivetrain? If the motor would come on top of the diff, instead of the side it should work. Any thoughts?

Should I ask Mike to make custom mount so I would be able to get the motor on top of the diff and get the driveline straight?

Hardstyle · 02.26.2009, 05:14 PM

Parting out the truck.

Here some measurements

93firebird · 02.27.2009, 12:04 AM

I wanna know what pinion adapter you are using and what pinions to use, as I am in the process of building a brush-less genesis. I want to use the 21t and 25t (like the nemesis) but I am not sure about what pitch,

Hardstyle · 02.27.2009, 09:25 AM

The adaptor/pininon what I used were bought at finedesignrc.com. But trust me, it wasnt good at all. I think that the adaptor/hub what they use is for boat applications. Im pretty sure Mike would do much better and cheaper adaptor for you

. I had there stock gears from the genesis clutch. Ps. I waited my order from finedesignrc about 6 months

Imo the 2 gear pinion is huge PITA, very hard to get the correct gear mesh in genesis trucks. Thats a part of a reason why I try to install center diff so I can get rid of the 2 gear pinion.

Hardstyle · 02.27.2009, 11:32 AM

This is what I have thought.. This is all in developement level. Actually the diff is gonna be a bit lower, now its just there cause there's screw holes. I'll try to mount everything so that I can get batterie(s) inside. Not sure what I will end up using, maybe lipos.
Theres two unused servo places, so I get rid of them and I think motor should fit there just fine. Opinions? Should I do something differently? How do I attach the diff/motor mount? HEEEEEELLLPPPP

Arct1k · 12:10 PM

Thats the basic idea - but use one of these with a Hotbodies diff off of ebay...

Turn it 90 deg so that you can mount the motor as you have it in the pics. Then you just need an extension to make the mount hit the sides.

Get a "normal" diff mount for the other side in the same manner.

I would then add some additional bracing between the diff mounts...

Hardstyle · 02.27.2009, 03:36 PM

Thanks Arct1k I appreciate that.

Yes thats the only way to do this. Sideways it would twist the axles to a bad angle..

About the HB Center diffs spur gear. Is it always the same size or can I get there what ever I want? More closely are these center diff cars only geared from the pinion?

The bracing I can make by my self, so its the thing what goes from side to the other side of the diff? So the diff mounts are solid?

Dang, this car will be a blast

, have to do some gearing calculations.
