Hi guys,
I was wondering if you could tell me how to work out the ratio when people say they have like a 8.03 ratio??

What pitch are they using?

here is the ratio for 72T 48pitch. that's the only ratio i use
72 SPUR GEAR
21= 8.60
22 = 8.20
23 = 7.82
24 = 7.50
25 = 7.20
26 = 6.92
27 = 6.66
28 = 6.43
29 = 6.21

hi lem! hehehe :D im still praying for the rain to stop so we can have the race of champions push through this weekend!

Could sb tell me the exact size of the one way bearings?!Thx a lot!

Take the spur, divide it by the pinion, and multiply that times the ratio of the transmission (2.5 in the TC3). So a 100 t spur with a 29t pinion would be: 100/29*2.5=8.62 ratio.

Hope this helps.

Thanks lem2. We're running 48dp I recon.

So do I.. so that I could watch the race of champions with out the weather disturbances... Hopefully I could come after office work..
:nod: :cool: :)

I'm not sure if this has been asked before, but has anyone here had problems with the steering rack binding up on them? Recently I noticed that there when sliding the steering rack from side to side, there are 2 places where it binds up. I have cleaned the bearings and bought a new rack, but the problem is still there. I checked the bearings pretty quickly, and even took some calipers to them to check if they were out of round, however, they seem good.

Is this a common problem? Should I recheck my bearings or are the posts most likely the problem? If anyone else has had this problem, let me know.

Oh, and does anyone know where I can get replacement bearings for the TC3 steering rack cheap?

where can i find a good place for hop ups at:confused: id like to get a aluminum center shaft, and a set of arms, if possible :tire:

try tower hobbies at www.towerhobbies.com they seem to have everything.

griffin,

sometimes the rack will have high spots where the bearing gets pinched a little. take a sharpie or mark where its binding and lightly sand with fine grit sandpaper where its binding. dont go too far tho, a little will do the trick.

I already encountered this problem on my FT TC3 recently. MarchTC3 suggestion is what I did and the problem on my steering was resolve..
:nod: :cool: :)

Really? I'll give it a shot, but it seems strange that the problem just popped up out of nowhere, and it happens with the old AND new rack.

I'll give it a shot though.

Progress on my in$ane tc3 project
 

Well heres were i'm at. System is in and running. Little more complex then my ss5800 was but I am sure it will be well worth it. I hope to have this out tommorro if its not raining.
