Look, please, between every pack that your tires are stuck well! Cyclone asks for a lot of maintenance and if you arrive indeed has to make it walk it be going to use your tires not a lot of time!
You use what as tires? GM / sorex 36r?

Hi all, if anybody know what's the difference on the reversible arm in the front between holes #1 and #2? What's the effect? Thanks!

i ordered a battery jig and some flux and iím going
to buy a 60w solder iron later today
so that when i build my next batteries iíll try to build it cleaner

other than that i think iím ready to go practice at speedworld

i just wanna go there with at least 4 battery packs.

so around late this month early may iíll head down to the track to practice

Man...you went straight to the 3.5 I'm scared of you So long as you had fun it's all good.

Hey guys, Im running at a small track. I have seen that my car isnt as fast as the other cars in my class (Super Stock 19T/13.5). Im using the following:

Intellect 5000mah 30C
LRP Sphere TC
LRP Brushless X11 13.5

My question is, can I keep going higher on pinions and lower on spurs? What is the limit? My car has 16T pulleys, and I have been trying to get 18T pulleys so it gets more top speed. Right now, Im using 98 on the spur and 38T on the pinion. I have been thinking of going 40T on the pinion or even 41. But im afraid that it will be too much for the Motor/ESC to handle. Im just trying to reach a Final Drive Ratio of 5.8 and with the 16T I find myself having to go too big on pinions... Can someone shed some light if it wont mess up my electronics by going to big on pinions? Thanks in advanced.

Right now your running a 6.29 ratio. When i ran 13.5 I geared arond 4.5, but thats on a BIG track witha LRP TC. I would say you can go down to 5.2 and be safe, unless your running a LRP SPX on the higher punch profiles.

For the 5.8 ratio your looking for you need a 98/41 or a 96/40. Just check your motor temps after a couple min's.


You can go to www.gearchart.com and create a gearchart.

I agree with Scott, the motor sounds liek it is undergeared. Go with his gearing suggestion and you should be closer to the ballpark ratio you need.

FYI, you don't really NEED the 18T pulleys. It just changes the internal ratio of the car so it doesn't require super huge pinions to get brushless motors geared correctly. They also have some added benefits of not bending the belt as much, so they free up the drivetrain a tiny bit. Even then, we still have to run some pretty huge pinions to get brushless spec motors geared properly.

So, you don't think if I could use smaller pinion for less load on the motor? Please correct me if I'm wrong again? Thanks!

Sure you can. I'm just saying since the internal ratio of the car itself is different, it will require a different pinion and spur combo to get the same final drive ratio.

Cyclone with 18T center pulleys has an internal ratio of 2.1667
Cyclone with 16T center pulleys has an internal ratio of 2.4375

Your final drive ratio which is what most people will use when comparing gear ratios on rubber tires (because the tire diameters are all about the same). The final drive ratio can be calculated with this formula:

(Spur/Pinion) x Internal ratio

So if the internal ratio is a smaller number (like the cyclone TC), it will take fewer teeth on the pinion to get a "taller" ratio because of the lower resulting final drive ratio.

You can almost ALWAYS achieve almost the exact same final drive ratios with either set of pulleys (execpt for the really extreme ends of the allowed ratios). It just takes a different pinion and spur combination.

Guys

Those pinion and spur numbers and gearchart result for 13.5 are based on 48p or 64p ?

Thanks
