So, here's an update with my nose-diving (downsiding in the air, hitting a jump) and the non-ballooning tires, issue....

Coming to find out, I'm under-geared.... I realized this, when I was searching this thread for the gear ratio of the 811-Be, and saw some dude's post, saying it was 3.38, the same as the Mugen Eco... So I thought a 16t pinion, on my T8 1900 setup, would be perfect... Well, it's just that I run on a little bit larger tracks (proper 1/8 outdoor tracks), and when hitting a jump at almost full throttle, it wouldn't want to bring the nose up in the air.... That's because I was already near or AT the top of the powerband of the motor, so there wasn't anything left up top, to bring the nose up. LOL... which is another reason, why the tires don't balloon when I hold the car in the air. It tops out at maybe 35-40mph, and probably reaches it's top, in under 10ft :lol:

Oh, and my motor hasn't even been over 130°F, after 10-15min runs at the track... so that also lends to my theory that it's undergeared.. lol.

I only have a 15, 16, and 17 tooth pinions, at the moment.. so, until I grab a couple more (maybe 18, 19, and 20), I'll switch to the 17t, just for a little bit more top end.. I tell ya what though, with the 16t that I have in there right now, this thing has monsterous power/torque everywhere on the track..... Just not enough top end, for any of the jumps that have a long(er) run up to them, though.. lol, so I'm trying to figure that out at the moment... not sure whether to haul-ass up to them, tap the brakes about 2ft before the jump starts, and blip the throttle, the second the tires reach the lip of the jump and start their 'airtime'.. Right now, I'm just cruising up to the jump at about 1/2 throttle, and goose-ing it at the lip, and that seems to work just fine... but, it seems that I'm losing about a 1/2 to a full second, on the slow approach..

Any other ideas, fellas? :)


Oh, and btw, I haven't pulled apart the shocks or diffs yet.. I'll be doing that this evening :D

There were 2 shims in between the bearing and pinion, i removed one, seems a bit better.

Can you turn it over easily by hand? By this I mean you can turn the centre shaft between your thumb and finger? If not then also check the amount of shims either side of the diff.

I opened up the front diff housing as i thought it was quite tight, re greased the 2 gears and screwed it back to together. Now its even tighter and is really hard to turn by hand, normal???

Also inside i saw that 1 of the 3 Phillips screws were missing, the side which the gear lays on, again is that normal?

Ive run the car for 2 battery packs now, it was in new condition when i bought it off a member.

I try the 16 tooth included with the kit but it gets hot 190 and then I try a 18t and it's still getting hot? Any suggestions? Im not sure if I am going in the right direction!

Pinions to start with, on average is:
2050 = 15t
1900 = 16t
1700 = 17t

Also, make sure you cut out the body in the front and open up the rear to get some air flow through the chassis, this will help with the temps.

That's just unbelievably sad news, TM.. Thank you for letting us know of his passing. He had just posted last week, didn't he??! Gosh, that's just tragic news. May God bless him into the heavenly gates above, and bless his family, during their time of grieving.

We'll miss you buddy, you were a friend to us all.


Very best,
