need advice ...... im running my TB-03D on a 22T pinion and 64T spur gear .... im using a 9.5T 4500KV brushless motor ......

newbie question?

is this ok? ....... any risk of damage to the motor? esc? overheating?

thanks in advance

hi strawb
your FDR is ok i think its around 7 correct me if im wrong

you FDR will not damage your motor dont worry :cheers:

hi papi jon

thats like the 64 divided by 22 thingy multiplied by internal drive ratio right?...... i dont know what my internal drive ratio is?

i think the FDR of that is 7.09

thanks papi ....

if you have, check you manual strawb..

if not, you can get it HERE

but you were right.. it's:

spur (64)/pinion (22) x internal gear ratio (2.438) = 7.09 FDR ~ 7 = advised FDR for drifting kits..

thanks papi lance ...... much appreciated

i ran the SP BL last night for about 10-15 mins and the cover for the pinion and the spur was so hot? is this normal?

the cover become hot not the motor? :confused: that is bit weird cover should not be in that temp unless you pinion & spur contact is bit tight that cause friction :no:

maybe my spur and pinion is tight ...... i'll try and loosen it a bit ...... how to gauge if its just right distance? ...... i dont want it too lose that it might slip

just cut a piece of paper put it in between the spur & pinion

The cover for the spur pinion might get warm because it is attached to the motor mount which is aluminium. Normally Tamiya include a paper 'spacer' between the motor mount and the motor. In most instances this is to avoid the heat of the motor coming in contact with the plastics and melting it...make sure you have a heatsink on the motor to draw heat away from the motor.
For getting the best gear mesh, the paper trick will work, but I prefer to set it by 'feel'. There should be a small amount of 'backlash' between the gears, but as you start getting finer pitch like 64dp it becomes more difficult to get right, and the same applied when using the paper trick on finer pitches....it becomes a bit of an art to get right, but eventually you get the skillz required

thanks for the tips ..... i adjusted accordingly and everything seems cooler now ....
