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.

so the 36t gear that i got is the same diameter as the stock bevel gear and fits perfect. however you could go larger for sure and get that 40t gear by just flipping the center diff mount upside down. this gives you another 3/8" of room off the chassis. you could maybe even make a 44t gear fit. i think the 40t is gonna be the ideal gear but we'll see how this one does.

dont know about drilling holes yet. the gear also needs to be milled out a bit. it is too thick and needs to have the center section made skinnier in order to mount up right. i hope they can pull it off otherwise its back to the drawing board and will just have to have SDP make a custom one.


here is my 37t spur that i am gonna have made to fit




here are some pics of the SDP gear.

is anyone familiar with these Navy esc's? this one sounds pretty good.

I had an etti, but blowed it due to wrong gearing... the throttle curve was a bit strange to me, but I probably could have played a bit more w/ the settings.

as far as I remember, the breaks were similar to my plane esc's in my buggy, break automatically when throttle is in neutral position. I think, compared to my plane esc the breaks were more instantly. I guess, they're well manufactured. but it got warm. they claim to have high quality and ultra low restistance stuff, but it didn't stay cooler than the plane esc.

those breaks are not a permanent solution; I had the 200a plane esc as a short term thing (which became permanent). modded w/ some caps and a fan very solid, good throttle etc, but the breaks just suck, when you don't keep the mechanical breaks.

to be honest, in every day use, I don't see any better performance then my cheapo-plane esc (200a, looks like a suppo, dunno if it's one).

about the hardening, take it to the local shop to get it done properly, it's not that easy. they should do that for a few bucks, regarding how expensive this hobby is, its worth it. go with the pro.

Hi mate,

Great thread! I've been wanting to convert my 5B for ages, but the motor mount is the biggest issue for me :(.

Anyway, with regard to looking for a digital servo, is it for steering or brakes or both? I run one of these for my steering and it's been bulletproof.

Multiplex Rhino Digi 4

Even when the steering linkage or servo saver gets jammed up with mud and stuff, servo keeps going.

wow, that servo is fast. so 200oz is enough huh? i hear lots of good things about the rhino. is it large size or regular sized spline? and do they make HD alum. servo arms for it somewhere?

There's a few places that sell the alloy arms for em, just google "multiplex digi 4 arm"

It's a little bigger than my std sized servos.

As for spline, I'm using one of the arms that came with the baja kit. It says "Hi 8mm" on it. So Hitec I guess. Only problem is, the baja comes with a few arms

Hi 8mm

So not sure what the tooth count is lol.

at first i bought the futaba s5050 for steering servo but i just traded it in for the HPI SFL 30MG digi servo so that i had the 8mm spline and could use the massive HPI servo arm.
