Xtreme, I posted back a page or so about the apparently German-made ring gears: They are all I've found in some serious searching. Not worth it to me to acquire them, but if there is another source for metal ring gears, I'd like to know too! Anybody heard anything?

This car has been a LOT of work to get built properly! But I'm an old-school kit builder, so it's been kinda fun. The big thing is, I used a 1/8"drill bit on ALL the supposedly 3mm. hings pin holes, then hadda do the outers AGAIN after screwing in the bottom shock mounts- They squeezed the hinge pin hole tight again, as they expand the plastic, the holes being so close together. Took out some serious material! Also shaved some here & there, but got totally free & smooth arms now.

I also ground off a bit of extra plastic from the front battery mount, as it can interfere with the steering rack on full left turns. My rack sticks out a few thou over stock due to my steering bearing fix (Mentioned back a page or so.) Also replaced ALL the kit ball cups with the short Tamiya ones.

All in all, I seriously cannot believe that this car will drive at all without everything I mentioned being done! Everything would just be WAY too tight to work, period. I also machined up some Aluminum diff outdrives for the driveshaft, so now all metal drivetrain except the ring gears. It'll be a while before we run 'em, but I expect two totally smooth-running cars now. Chris REC

I knew this was an older post and these cars probly didn't have a huge following, but I hoped to find some parts. I just recently got mine super cheap off eBay and had couple issue when putting together and saw need for some improvements. I did find some spare parts and ordered all I could. I dig the little chassis amd have a really cool body for it . Let me know if you find anything, thanks

'Nother thing I feel is important: I ordered some diff shims for the diffs themselves, and also for the outdrives. I guess it's my meticulous Machinist's nature, but gears mesh only one of 2 ways: Correctly and Some Other Way. Odd that this is the one thing that's looser than a goose on these cars, wnen everthang else is tighter'n a teenage...Ah....Well, awful tight! I think it'll give me better gear life, and possibly help avoid crash breakage, but either way can't hurt right? Chris REC

Sorry Mate, that I can't do. They're one of the perks of being a Machinist. I can't charge squat for 'em and they take time on the lathe and the mill. The stock ones, I think a couple extra come in the kit (Tellingly,) so while you're getting other stuff grab a few extra & you'll be set for life, I imagine. Chris REC

I don't know about best, but I only use a silver can. The factory diff cups are so soft they deform easily per pictures a page or so back. It runs real well though. Honestly much better than the old HPI CupRacer which is also shaft driven.

I've had a lot of fun with this car so far. I guess the best for me is that I can still use my old NiCd side by sides no problem and weight distribution is good.

So I am taking the M.rage in a crazy direction...

It has foam tires, 17.5 and I'll likely thrown in boost until the motor is up to temperature.

I am still running stock diff in the rear but went to spool in the front. The diff will likely melt quickly as I've already managed in the past. I tried to order from nitro rcx but shipping in 36 usd to canada so I was forced to look into alternative diff options.

With a bit of work a spec-r gear diff for a tb03 may just be perfect. I did some initial fitting and i think it'll work. Had to order a casing as this borrowed diff was busted.

I'll need to dremel a touch on the inside of the diff housing and use a lathe to cut the notch for the bearing 0.5mm in. I'll file down the shaft to fit the metal bevel gear option and make sure things fit. It should drop right in after that.

I'll report back with pics. Think this may really help longevity and consistency in handling. Too bad gear diff with metal outdrives isn't an option part for this kit

Mkay so! Got the Girl's car done, and mine is waiting for a few bits: Then we'll be off to try & get her involved, cross fingers.....I only have 1 worry, which is replacement parts- I can get everything I need, except for a-Arms.

They will likely be in stock one fine day, but I want an extra set before we even go out to the track. Hence, I am appealing to you fine chap's good natures to hook me up with some. I know these are highly coveted, but I also know some of you bought up a fair amount of extras & can easily afford to he'p a guy out (You same guys are probably why the cupboard is bare now, so karma sez.....)

Kindly let me know if you have a set- Or two- of arms you'd part with, I'll go a couple extra bucks on 'em since it'll likely be a while before they become available again- If ever. My thanks Gents! Chris REC
