I have been using one of those baseball bat shaped lunsford wrenches. must be 1/8" since that is a hair bigger than 3mm. Only problem is this wrench is too fat to fit the rear camber links.

I tore the diff apart last night night, lightly sanded the backs of all 6 bevel gears and the face of the "cup" side of the diff half then reassembled. I did the face of the diff half after I noticed how much it had puckered from the self threading screws. It all seated back together much better and is now very smooth. I guess I should have paid attention a little better in diff building class.

Need to figure out a better cooling method for this thing or force fans in there or something. She's getting toasty though after an 8 min race, pulling off at 180 with the 25/35 pinion spur setup.

Really!!? What wind motor are you using? Dynamic timing or blinky? I am running a Noval Ballistic 21.5 blinky geared 33p/35s and after 8 minutes it's only at 150 degrees.

Maybe it is getting so hot due to being under geared.

My 21.5 ThunderPower came off the track hot too. No timing and blinky running a Justock ESC. The case was nice and cool, but the endbell temp was through the roof after 8 min. I'm thinking 32/35 was allowing the motor to over rev. It sure felt good. I'll think I'll try a 34 next and temp without any other changes.

Brand new 21.5 D3 with an RS tekin on blinky and 30-40c battery

I only have the top vent on the body cut out though

Guys - Weird problem, I think. My gear diff housing isn't perfectly round. Couldn't figure out why I was getting binding so I ran the calipers around the teeth. Sure enough there is adopt where it binds. Have I done something wrong or is there a drama with the gear itself?

If you tighten the screws too much on one side you will distort the diff gear

I would suggest reading the article on 3 Racings website on how to assemble a gear diff

Pulled the diff apart and checked the gear on its own, out of whack by the same margin Only talking 0.1mm here. Bugger.

I can sort of adjust it out my tweaking the bearing carrier, but then there is barely any gear teeth meshing....

Got my servo and finally got the car together....

Anyone else displeased with the battery mounting system?

I have a Gens Ace 5000mah 40c battery that's too tall and hits the ball cup on the servo saver.

I have a smaller Zippy Flightmax that really just floats around in there.

It also seems the ESC mount/battery door isn't stiff enough to really hold the battery in place.

Should i just get some strapping tape and tape the battery in?

I just got the v2 arms and they did a nice job beefing up the upper front arms. Can't tell for sure but it seems they use the same plastic and did not thicken the bottom front arms. Hopefully with the thicker upper arms the bottom arms will less likely break.

And on the subject of the new front suspension. I'll let you guys beta test them. The FGX maybe inexpensive but like the real cars replacement parts can get expensive.

Don't remember if this has been covered, but, F104 kingpins fit the FGX. Found out by chance today. New front arms arrived today, but I broke a spindle yesterday, will have a replacement this week. But I'm growing weary of this
