So I got another silver can and put a 104 spur with a 29 pinion and guys were faster then me running a 25 and a 104 but besides that my silver can running the 29/104 combo blew after one 5min run ???? I'm using a wolf pack 3000 batt with a tekin fx what combo should I put in there where I'm gonna be fast and not blow the motor ?
That is a lot of gear for a silvercan, especially if you are on rubber tires which have a large dia.

Normally you would gear a silvercan based on temp, buy a temp gun.
Try not to let it go over 200f, 150f is optimum after 5m.

10 to 15m runs with todays lipos are easy to do on the rug, but not so good for silvercans, maybe a practice motor & race motor is a good idea.

All silvercans are not the same, not even close to the same.

21.5 blinky is so much nicer.

Default Hmm

I blew my silvercan last night, hit 200degrees and cooked the comm. Between the high traction and the foams wearing down, it was bound to happen. Car was super fast though lol. There is definatly a variability in the motors. With that said, what is a good conservative rollout to start with for silvercans? We are running on foams.

Installed.

F104Pro with pretty much every alloy hop up you can get for them... except alloy knuckles. This car has not missed a single beat. Running 3racing wing set, boosted 17.5 turn setup, tamiya wheels and tyres, 60g weights on each side pod, just installed heavy pivot post and rolling damper and split top deck. Also got the counter weight but have not installed yet.

And yes my front tyres are knackered :P

Hey Lorddude,

Did you see the video of the IIC F1 race in Vegas?

You might wanna consider mounting your transponder up front cuz if Hiro had his back where you have yours he would have lost that spot, at least electronically.
I had a race go that way, I crossed the line in second but my transponder was up front and the other guy's was further back. We all knew he crossed first though but the computer saw it the other way.

ok guys, this thread got me exited about f104 racing, so I'm reading up on the parts I need. I will order the f104x1 and some other stuff, but I'm in the dark about the tires. I want to run rubber only, so wich tires for indoor (carpet) and for outdoor (MACH Heemstede Netherlands). Tamiya, Pit, Ride, etc, etc?
For outside try Ride soft front-medium rear at high temperatures. At low temperatures or rain try supersoft front supersoft/soft rear. If you pick an 10.5T BL or below definitely try them.

ps: love your track by the way

Watch out matt, im hunting you down next race !!
actually what is the purpose of adding 60g for both side ??? to make it more roll ??? will it becomes more oversteer if more roll ??? it's a bit comfuse.........

secondly, do we need to add more weight on radio side in order to compensate the ESC+wires(eg. 80g on radio and 60g on ESC) ???

thanks~~~

the weight gives the handling characteristics of an f103 where the weight is distributed along hte width of the chassis. It was recommended in this thread a few pages back, and it works really good at my track.

Balancing a car is overrated :P

Tamiya's David Jun has even recommended putting weight up high in the airbox on the body of the F104, less weight up hi to get the same results as more weight down low.

Offroad buggies been adding weight to the top of their trans to get this effect too.

The part number has the size in it ie BA1060 is a 10x6 bearing. In any case:

10x5x4 4 Bearings - Front Wheels
10x6x3 2 Bearings - Drive shaft
12x8x4 2 Bearings - Inside diff (only one needed if you dont run stock spur gear)
11x5x4 1 Bearing - Inside diff
