Status: offline 		CEN forum doesn't seem really busy at the moment, being winter in the northern hemisphere and all. So I thought I'd give all y'all something to think about or reply to.
My goal for spring is to have my MT2 BULLETPROOF. Just wondering if anyone has any suggestions or tips for me that I may have missed.
Here's what i've done so far.

Aluminum break seat, steel vented brake disc, CEN aluminum shocks, titanium front turnbuckles, Laid down 645-mg steering servo, ofna 125cc tank, OS .18CV-RX, Stainless screws, CEN upgraded diff parts, Custom top plate that goes back to the brake seat, Custon built(very ugly but strong) roll cage, venom failsafe, 5 cell hump pack.
I also sealed my servos and my reciever/batt box.

I have the necessary parts on the way to do: the swift shaft/hub mod, genesis spurs and CEN steel pinions, and some ARO shock towers. Still need to buy rims and rubbers.

What else can I do to this thing to make a good basher? I broke all my shafts and dogbones so I have to wait for parts anyways.

Status: offline 		Well, they finally changed their site to include the funfactor. 70 USD though.. tempting bu t i may wait a few months. My home meade one cost me about 7$ CDN lol.
I'm kinda thinking that the A arms and dif cases will be the weak link now. I know if I put New Era arms on i will end up breaking lots of diff cases. I broke one with stock Arms already
Has anyone treid anything to strengthen the Arms or Diff cases?

Status: offline 		just remember its best to have flexy parts here and there, such as the arms, they allow flex and save damage further down the line. u cant make the whole truck completely solid - well, not really... better to have a couple of $5 bits break, than the whole chassis and diff cases etc taking the strain, imo

sounds like u are about there tho - the shafts, cups and chassis flex are the main issues, spur gears, if u are running uprated engines and/or running in sandy/stoney areas, are worth uprating too imo. so it looks like ur pretty much covered - theres tons of pics of mine about, and that has taken a couple of very hard 50mph-ish smashes with no real damage bar a broken jt shock tower and cosmetic stuff.

just keep an eye out for a jt racing chassis - they are brilliant... and oh so rare now it seems...

Status: offline 		I kept snapping antenna noodles off in the radio box so I bought a New Era antenna. I also bought a New Era front bumper/skid plate!

As for the stupid diff cases...I have broke 3 already. Cracked off the little nub that sticks out with the two holes in it. One hole mounts the control arm and the other holds nothing...I gonna try filling that hole with epoxy to try and give a little extra strength. My origional idea was to make some out of aluminum on a CNC machine...but I have no CNC machine. Just software!

I can draw the diff cases in AutoCad or AutoDesk-Inventor if someone can convert these files to run on their machine!?!?!

I have also bought "steering metal parts"

I decided to leave the red plastic spur gears. I had a malfunction once and all that happened was a spur got stripped. 4 bucks for a new one is better than a diff rebuild or snapped dog bone!

ummm...oh yeah...I put my servos, radio gear and venom smart temp/failsafe all in clear baloons because I like to run in deep snow.

OH..and the stock 10x15x4 bearings in the diffs seem to pooch out fairly fast...so I bought some double sheilded/sealed ones off ebay! 10 for about 20 bucks!

Status: offline 		yeah, I'm planning on keeping the sotck arms, but i was thinking baout making some kind of diff case brace accross the wo that the arms pull on eachother not just on the plastic case. I've already replaced the bearings.

Boot, Idk if you still have the pieces for your diff cases bit I borke a few like that and use a ton of crazy glue or plastic epoxy to put it abck together and it holds just fine. Just so you dont have to buy diff case halves all the time. Aluminum diff cases would look sweet and perfor well as long as you kept plastic arms. With metal arms and metal diff cases you would probabaly bend the chassis. I've got the alum steering link on order too, I hear it helps tighten up the steering.
How do you like that new era skid plate? I was thinking about it but never did buy it.

I've been looking for a JT chassis for a while. Wish I would a bought one when i first got this thing but 130$ US seemed steep. But with this extended upper chassis plate it should be strong enough.

Status: offline 		You should PM DrHonda and talk to him about CNC'ing some parts from your drawings. I am sure a couple other people (like me ) would jump in and buy a set. I like the idea of an aluminum diff case.

Status: offline 		Instead of the JT chassis how about the Magnums chassis? It uses the same diff cases, throttle servo location, and engine mounting and it is bound to be a whole lot cheaper that the JT chassis. Even if it isn't that much cheaper it is atleast available.

PM me with what you have. Billet alloy diff housings have been brought up before. Perhaps it’s time to look into them.

Status: offline 		dustin7837 - I have been using plastic epoxy and JB weld on the diff cases but it keeps snapping. I will try more...Loads more. I will tell you how the skid plate is when I get it. I ordered it a week ago!

Dr Honda - I dont have anything drawn yet but I suppose I could sit down and draw the diff cases sometime soon. Those would be totally sweet!!! SO strong... What file types can you deal with best? I think Inventor is "*.ipt" which would be easiest for me.

Let me know!

Status: offline 		Dustin,

You can fing that cage on ebay for $40. There is always 1 or 2 from the same seller on there. Starting bid is 30, buy it now for 40. Dont remember the shipping cost though

Status: offline 		if this turns out to be a do-able exercise, could u mod the casing to have 3 screw hole for the tie bars to screw to? just adding one in the centre of the existing 2 would be great if poss?
