Its just tuned to accomidate the feel you want from a touring car. The Steenari one is for an off-road powerband. I don't know about a "twisted" comm though.

i have heard about the twisted comm and the stack size. i was wondering is the stacksize more or is it less than the touring/mod?

im contemplating on what are the effects of a twisted comm.
more overlapp would it equate to more rpm? im not sure if i got its physics right. pls feel free to correct me if i am wrong.

As far as I know, the twisted comms motoros are only sold in japan and europe. I recently picked up a hara edition 10x1 and it did NOT have the twisted com. I was kinda dissapointed lol. But yes, the twisted comms give crazy rpm.

its also more efificient (sp?) because it charges the next com segment while still on the last one and also decreases brush bouncing i think

I think it's a give and take. More brush overlap usualyl means it will be less efficient, but the smooth transistion comes into play as well.

Your right, the twisted comm is less efficient as it creates much greater overlap.

Over here in Europe the Hara did have the twisted comm but we have not really used it all year. It also has a smaller web arm - 3.5mm as opposed to the touring version which is 4mm. This also produces more revs but it lacks torque - you would normaly gear a hara 1 - 2 pinions lower than a revolution touring.

We have just found that they get far too hot and are too inefficient for 12turn racing. We have mainly used the 12x1HT touring all year

The Steenari has either a 4.5 or 5mm (cant remember) web arm. Much the same, if not identical to the old core arm. Although it revs much lower, it produces a heap more torque than the hara and more even than the touring version. Designed for off road it has actually been really good in touring running sprint brushes and 10mm timing or 25 degrees (This is past the last timing mark) Because of the torque you can gear at least 1 pinion higher than the touring version.

Just to finish off though we have just tested Spashett version 12x2 and 12x1HT and they are both STUPID FAST!!!!!!!

Spud,

I have to agree with you, the Spashett Editions are by far the best motors I have tested so far!!

Besides, they match the Pro4 so nicely!!
