Holy crap that is huge! Nice job Neil...so what are your intentions for the trans... Those massive wheels actually do not "look out of place" on that truck at all.

Awe Inspiring ! Looks Tits my friend.

Sorry for all the Q's, but I'm intriged.
How strong will those axle shafts be with the hub adapters stacked like that for the width addition ?

I found some pictures of aluminum axle housings on a forum but can't find a distributor, Can you provide some links of the sellers your using for the after market parts for this beast your building ? I know New Era is one of them.

I read that your power plant will likely be a M.M.M. or a Pro with a L or XL, what voltage have you ultimately decided on ? I've also seen pictures of guys whom installed a Emaxx tranny and it seemed like a decent idea, but not knowing the durability of the stock trans is it nessasary ?

Thanx Neil.

3905 tranny should fit nicely, just needs some L shaped mounting brackets that I'll fab up once I have the tranny on-hand to play with.

[What's_nitro?]

Soooo.... Is it a 1/5 now? I can't picture it being 3" skinnier. The extra width looks natural.

We will see really- gonna do some stress testing by molesting the truck on the bench

If you search ebay for 'txt-1', and set it to 'worldwide', it does turn up a fair number of smaller ebay shops selling various bits & pieces. I also have a long list of places on my website under the 'Truck links page'.

The stock trans is pretty durable, but since its a crawler-esque design it really reduces the speed down far too much to be any good for anything over about 20-25mph- cant use larger than a 20tooth pinion & cant change the spur gear either. I think an MMM will be in order given this thing will end up weighing about the same as the Gmaxx (~13lbs), but yeah, probably a Neu 1512 or similar sized motor in the ~2000kv range, geared for 30mph tops. I think 5s lipo should do the trick- spin it faster & gear it lower to generate more torque at the wheels, plus I can use the same lipos from the Gmaxx, though I am gonna get a couple more Turnigy packs, just gotta do some measuring up; I would like to use the stock battery tray from the TXT-1 if its big enough, otherwise something form Mike custom made to size.

I'd say maybe 1/6 scale, its big how ever you look at it

[Bondonutz]

Thank You for the answers and links Mr. Neil.
Please post more when more progress is made.

Neil
Have you thought about making a custom frame that is longer to help out with the suspension travel? I'm going to run the stock tranny in mine until it blows up. I plan on using a mmm/neu 1512 2d f (2600 kv) running on 2s as a starting point. Is there anyone that makes stronger gears for the axle's?

[suicideneil]

I have thought about a custom chassis actually (great minds...), only issue is making it; I would probably get the Candyman to make me the plates as he's cheaper than a proper machinist, and has a flair for this sort of thing too- even then though, I cant see it being cheap. What Im probably gonna do it just use longer cantiliever push rods- doesnt need mega suspension travel or articulation, just enough to be 'useable'...

As for gears = no, saddly. I've seen someone make a custom spool that uses a larger 'ring gear' and smaller reduction gear thingy above it, I think using a pinion on the shaft and a delrin ring gear, but that was in a custom crawler to get lower speeds. Trouble is really it uses too many gears in the axle- cant just find a new 1/8 diff to stick in there, got to replace the upper reduction gear and the two pretty small bevel gears that change the drive direction 90*.

Ultimately, if the gears in the axles prove to be too weedy, then I will probably pick up something from rc4wd.com, they have a wide selection of aluminium axles that use the simpler ring & pinion gear design, much more durable in theory.

Interim update:

After 3 hours of searching, researching and measuring up/ use of The Force, I settled on some shocks:



Ofna 9.5 RTR fronts, two pairs from ebay; havent built any shocks in kit form for a long time, so it'll be nice to have aplay with them and choose the oil.

On that subject, any advice or part numbers on firm springs that will fit is very welcome- according to the specs the springs measure 16mm on the inside, 19mm on the outside- the kit comes with silver springs as standard I believe, which are probably soft I imagine, but we'll see how they feel once I have them with me in a week or two.

If these shocks are from a 9.5 violator then these should do, actually even the 13 MM big bore shocks fit but have a little side to side play because of the size difference..

[suicideneil]

Ah yes, 40072...

Thats one of the reasons it took me so long- one place says the shocks they fit at 12/13mm bore, others suggest they fit the larger 16mm bore shocks. I looked at the violator manual and it suggests the shocks are the smaller size, but various site listings have them as being for the larger shocks = mucho confusion. Nay problem though, I'll see how they feel once they arrive.

Funny you said that, what im thinking is that ofna is now using the jammin 16mm big bores for there mutilator (basically a 9.5 truggy) I also seen alot of cross references to the 16MM big bore yet I have a set of 9.5 violator shocks with me (the old cr-x1 shocks) If I measure them then yes they would be 12MM. I guess best bet is to just wait and see what the shocks lok like when they come in?

[suicideneil]

Yeah, I'll wait and see.

Update: The lightweight chassis rails have arrived

Need to get some oven cleaner before I can strip & install them, so photos will follow at that point. Funny thing though, or cool thing I should say- they cost me $120, yet the nice person/shop in Japan I bought them from put $16.70 on the customs label! Hah, dude saved me about £20-30 in import, VAT & handling charges- my faith in humanity is restored once again...
