that sucks! dismantling? why?

Just do like I did, bring your truck to the lhs and kindly ask to test fit the body from one of their 5t display trucks. No display truck? Hopefully they have a new body to try then, again ask nicely and they might take it out of the packaging as it only needs a couple staples to seal back up. FYI the HPI and Proline 5t bodies are precut (all hpi's have a cut out around motor also) and need only a little finishing with a sanding drum for the edges. But being precut makes it harder to make changes in wheelbase, without making the wheelwells huge.

thats a good idea. i was thinking that same thing. my lhs usually always has either a 5t or a 5b on display but when i was in there last week they didnt have one. i will have to stop in there next week and see if they have one in. i think the 5t body will fit but would be nice to check before buying. i recently bought one of those FG Beetle bodies thinking i could make it fit so i paid $140 for it and it doesnt fit well at all so now its on ebay.

I picked up that Neu on Ebay for $377 shipped. Finally got a good deal...

Didn't I read somewhere that RC-Monster Mike is using a Hydra HV180 on his Baja? How is that working for him?

[Ryu James]

thats a great deal Kaz. are you gonna be converting your rampage? if so, i could have one of these motor mounts made for you. i will post pictures of mine when its done. should be done next week.

got my spur gear today from SDP. it is by far the best quality gear i have ever seen. i am worried my machinist will not be able to drill holes in it. i am taking it down there today so i will find out.

i will post some pics.

mike is using the hydra 180 hv on the baja and said it is surprisingly smooth.

i have learned the hydra doesnt have braking though so that is a concern. i want to build mech. brakes on my rampage but i wanted the esc braking as a back up in case i run into too many issues.

[KaztheMinotaur]

Yeah, I think so.

What size gear did you get? Is there room to get a bigger one? Let me know about drilling holes? I think we will be screwed if he can't drill into it...

LMK about the motor mount.

Are you sure about the brakes on the Hydra? I had one before and there was a brake option on the Castle Link.

PM me your email and I will send you pics of disc brakes on a Rampage.

[BL_RV0]

I think those are drag brakes.

[Ryu James]

here is the break setup i want to run. this is from a 1/5 Nutech/Smartech. i cant find anywhere that sells parts though except for in AU and it is $50 to ship. however, Redcat becomes the new USA dist. for Nutech next month and then they will have the parts. anyway, i just want to buy the complete diff mounts, top plate, and brake parts and i know i could make it work on my rampage. imo, this would be the easiest brake solution.

[BL_RV0]

Can't you just bolt up a 1/8 brake setup?

[suicideneil]

1/5 scale parts look somewhat larger- remember its alot more weight to stop compared to a 1/8 buggy ot truggy..

[Ryu James]

although the 1/5 parts look identical to a 1/8 in these pics they are actually much larger. the 1/8 stuff just wouldnt work for reason like neil stated.

anyway, kaz showed me a pic of some integy brakes mounted up to a rampage so i went ahead and ordered 2 sets of these. one for front and one set for rear. i hope i can make them work.

another thing i would like to do but not sure if i will is to get a 1/5 viscous diff like this that is normally used in the rear for a 2wd 1/5 but make a custom center diff mount and use it for the center diff. this unit is for the Nutech buggy.

[KaztheMinotaur]

How much is the NuTech diff?

[_paralyzed_]

sucks when your only option is intejunk, but I'm sure you'll make them work. Looking awesome, anxiously waiting for vid!

[Overdriven]

I thought you were on the right track with the neutech setup, looks like a center diff in there too. If you're thinking about doing the rear diff from a 2wd 1/5 in the center, FG/Carson/Duratrax have a nice simple plate mount similar to a standard center setup I'd look into. The mounts are cheap, the FG diffs not so much, maybe the clones would be cheaper.

I hope the baja brakes work out for you. I think the rear knuckle looks like it would be easiest to mount to. And if you keep the solid center drive you'll still have 4 wheel braking, even with brakes only front or rear.

[florianz]

hey,

what about installing the front break at the front diff, like they did it at the rear diff of the lrp buggy:

like that you can keep the motor where it is, keep the rear break at the center. you only need a long, stable pushrod, you probably need to drill a slot into that beatuiful steering-plate to have enough space for the disc, maybe a little slice in the chassis as well. and you need a mount for the diskbrake. it might be very thight, but I think it should work. just take an "outdrive" or diffcup which can hold that disc. dunno how to describe it, but it's not that difficult I think.

it should be lighter and cheaper then these baja/fg-aftermarket breaks. sure, they're cool, but also expensive and heavy.

I don't think you should run a heavy truck like this whith the breaks of the esc. first problem is, there are only a few esc's around for 10s and w. proportional car breaks. maybe a mgm (which I don't favor) or Lutach's esc.

if you go for a boat/plane esc, if they have a break, its like full break or not.
I have a plane esc in my buggy conversion, it's great (solid, smooth, reliable) but the breaks are just cr*p. well, kinda got used to it.
you could take the hobbywing pentium hv, it can handle up to 12s, add some caps, probably a fan, and that's it. the're quite solid and have a good throttle.

btw, I really like that truck!
