Default tc3 gearing/ monster

there is a wide range of gearing ratios you can use on the tc3,i assume you are running the car outdoors on a r/c track?
first job is to look at the track, is it a technical track, more infield corners than straits, how long is the track,try and practice using various ratios to get the maximum from your motor, as a example using a 72 spur and a 27 pinion the gear ratio would be 6-66
or a 73 spur and a 27 pinion the ratio is 6-75 or a 74 spur and a 27 pinion the ratio is 6-85, as you can see by changing spur gears you can maximise performance from your motor

Just before the end of the longest straightaway, the motor should reach peak rpm. That will give the best performance in the infield and straightaway.

i just ran a monster in my tc3 on a very large track last weekend, the gearing that worked best was a 72/22, the motor reached temps that were too high if i went with a bigger pinion, with the 22 had good straight speed and came out of the corners well, and was still getting pretty hot, about 160 degrees

i found the ally steering rack great. It gets rid of any flex or bend that i got in the plastic one. A great investment. But i spose having almost every part of my TC3 ally its all good. It handles better and looks great. esxpecially on me Blue warpspeed demon on the way

paz have you ever thrown those aluminum arms up on a scale and compaired them to the stadard arms?
i one of my arms pretty bad last summer,the thing just blew apart and i was thinking about getting them but i was discuraged because somesone told me they would bend, but now that i think about it, if that happens you can just take a wooden mallet and tap it back, but im more interested in the weight diffrence?

I think Trinty and Hardcore racing make spur gear adapters. IRS stuff is top notch so you cant go rong there.


Aluminum stuff is quite heavy. The problem is that instead of breaking like a plastic/ graphite part it will either bend or tranfer more energy from the impact to the next part in the chain. When you crash hard enough to break a regular A-arm, you usually bend a hinge pin. I would imagine that with aluminum arms you will bend a ton of hinge pins plus stretch out the holes on the suspension mounts. Caster blocks and steering blocks will probably be breaking with more frequency as well.

As far as bending aluminum back with a hammer, you will never get it perfectly straight again. This will cause all kinds of inconsistent handleing issues.

Thanks for the reply,well i don't like aluminium arms at all,they bend and they are heavier then the stock arms,and brands like GPM dont fit well...my friend bought the GPM aluminium arms and the fit was horrible.
