edwintklee,

The timing can be increased to maximum and the punch also, if you are using this in a mini. The temps will increase, however the RPM will increase and the torque will be reduced.

In mini with the punch at maximum you will cause more tyre wear, however the timing is up to yourself. Dependant on whether the track is small and tight,(less timing), open and flowing(more timing).

You will need to test this yourself by comparing laptimes. I know this question has been answered many times on the mini thread.

Never mind.

Regards,

Calvin.

Your only half right.

the 8.5T motors and lower all have true 540 rotors.
the 9T and up all use the 380 sized rotors.

This is why so many of us on here advise against using the higher turn motors in a heavier car.

Thanks for your reply, i was guessing that the result too.

due to i am using it on m chasis, i probaly have to tune my timing to fight against the other guy on my local track,

Thanks calvin, due to my local guy its always passing me at the straight, i guess they have tune the timing, so i have to too....

Um so gearing your motor up for more speed is not gunna make the motor hotter?

I think you are going to find that there is going to be a sweet spot for each driver/track/motor.

For me i always associated less timing with getting more run time and limiting the power of a motor with the old brushed motors.

However, i have also always assumed (so someone correct me if im wrong) that on a really big open track it may be advantageous to turn the timing down and gear the motor higher.

The question has been asked and answered a million times . All that has to be done is go back a page or two ...... EASY

Otherwise this forum will be filled with the same question being asked a million times.

Enjoy

With a 13t motor i suspect timing is more than likely not going to make a significant difference with regards to having so much more speed that someone can pass you on the straight.

With the right timing you should see differences in lap times, however, in my opinion the issue is more likely to be the result of one or a combination of other factors including car setup, tyres/inserts/rims, driving style and diff/spool used.

Has anybody's EZrun brushless system broken down or come faulty yet?

http://www.nitrorcx.com/ezrun-brushless-combo-set.html


And would the motor bog with a 7.2v, 6cell, Ni-MH?

grategenin,

No the system seems to be reasonably stable. However not sure what your application is for this sytem. I noticed that the link is to the 3300 KV motor system which is faster than the systems we use in Mini. You just need to remeber that these motors are 380 size in a 540 can.

edwintklee,

The timing at full will give more top speed, but less pull from the line. However Martin is correct in that if your car is not setup properly then the difference may not be noticed. The advantages of more speed can also be negated by pushing wide on corners, etc.

The faster you get your mini going the more crucial your setup becomes.

Regards,

Calvin.

That is true, the ones I am speaking about have a heatsink type appearance on the can and are a sensorless motor. They use a 380 size rotor which is what the Mamba Max motors use as well.

In the case of these motors, I wouldn't run them in a car over 1500 grams.

It's a 380, but it's the same size as a 540, if that makes sense

you are probaly right? i probaly need to get my shock to work probaly, i am still at trial and error with my shocks...currently using TRF long shock with Mini shock sharf....with 2 o rings...

not bad, but will wan to improve my car handling, we are runing on recycle 1/10 30% or less foam tyres from gp cars and run until we finish all the foams....

what to do we here race very budgetly....

an eve ncheaper way of racing minis is to ask the nitro racers if you can have their worn out tyres they give you them for free. All the mini racers (when they turn up) at the track use them, and on tarmac they work well. Apparently they slide a bit and give some margin for error.
