3:1 Gear-Reduction for 1/14 scale Tamiya's Semis-Trucks
here now my newest gear-reduction !
this way you also can mount larger motor's , like this 12 volt 17 turn 550 type "powerhouse".
Since this gear-reduction is mounted on the input-side from the transmission ,
it also can be used for Trucks with short wheelbase .
more info soon........
the gear-ratio on this gear-reduction is variable , depending what pinion's are used .
The max gear-reduction is 3.8 to 1 on the motor-input-shaft and about 0.8 to 1 on the output-shaft ,
what = about to a true 3:1 gear-reduction .
since I use hear a 13 tooth pinion ( 14 tooth on the photo ) . Original is a 10 tooth pinion used .
The pinion on the out-put-shaft has a 5 mm bore instead of the usual 3.2 mm
( because of the size of the main-shaft of the gear-reduction )
I will produce these gear-reduction's in a small series ,
means , they are for sale .
