Does it really affect the performance?

HPI R2 motors are very much similar with the Orion Katana motors. Both uses same orion based can (TOP) and the endbell as well. I dont see any difference between the two except for the sticker.

Hi!

My friend and I run the Kawada VX-R 23t motor at speedzone. The Kawada is an RPM motor... ...I think. But it also produces the amount of torque required for the track. The Kawada heats up more than the HPI R2 23t but I think its ok and normal. It also has a built in cooling fan just below the commutator of the armature.

I have the specs but it's on PDF file which cannot be uploaded or posted here.

Kawada new VX-R
http://www.kawadamodel.co.jp/moro_in...004/index.html

I'm using 5.8 (large track) to 6.2 (small track) ratio. It's by far the most stable machine-wounded 23T I used so far. It does hotter than others but the buildin fan doesn't cool it down a lot I guess. I had one burndown already and almost got 2nd one burndown. Remember to put a heatsink for this hotty..

Try using the 3Racing heatsink with built in cooling fan on your Kawada. It will help.




Available in 7 different anodized colors.

as far as the RZ goes.. I know if a few tricks but it will not come near 40000 RPM... the most I have been able to get from the RZ is about 37000 ish

Flatout 23t and Techtro 23T motors are really fast. Especially when equiped with silver brushes. Orion Katana 23t motors are fast too. You guys should try those.

during last weekends carpet race.

i used my Tamiya RZ for the 23T qualify.

i did all the usuals and used a pair of Trinity 4503 Brushes for both + and -.

i tweaked the + spring a bit.

the car was very very fast it took me by surprise with loads of punch.

but the downside is, i burnt the motor before the 8minutes, possiblily the gearing was set incorrectly, I was using 6.2.

next time i am going to try it again with a more safer gearing ratio.

both the new Orion Katana and Kawada 23T motors were very fast stock standard as well. Worth a try.

I have been using the Tamiya RZ for a little while now for 8min racing,

for tuning I use XXX brushes (stock springs) and shim up the arm with teflon washers. and then gear it at 30-31 rollout,

the XXX brushes seem to not go off over the 8 mins,

Talking TWEEKED 23 turn

Just kidding!!!

A lot of the previous threads are all good suggestions. When I say Tweeked, I should have said tuned. Align the brush hoods, shim the arm to the proper location and spacing. Proper brush and spring combo. Turn the com to the proper diameter. No big secret, just good common sense tuning!
That's it!

Brush hood aligning tool will do the work. There are many brands that maybe your lhs might have. Although there are different versions and designs to choose from. Kose came out with the most unique design. very useful to add power to your motor.
