Didn't roar approve the little 1s pack that crc had made for the gen xi ? Why wouldn't they change the rules for some one in the tc market ?

Actually, compared to real cars, our current TC shocks are inverted.

So were BL motors and LiPo batteries at one time. As long as the pack has a hard shell what diff does its shape make?

They made the rule for a very good reason. How would you like it if someone came out with a pack with a definite performance advantage over everything else but it only fit in one car? Not only would you need to buy new packs but a new car as well. That's why they mandated that any car designed for a smaller pack had to be able to fit a standard pack as well.

Personally, I like Cyrul's recommendation from years ago. Every couple of years, reduce the maximum size of the packs to keep the mah down to a reasonable level. That would also open up some new possibilities in car design.

Yes they were but this rule was just written last year. It states basically that you can not design a car around a battery pack. That the car must also be able to fit a conventional battery that is for the class you are running it in.

Yes but their car also fits a normal 1S pack with no problem. SO it fits within the rule.

Not all TC designs are identical. I had a lot of success with my centralised TC6 this year. As a few people have said, to improve the layout requires batteries of a different shape. But with shorties and saddles of various sizes, interesting things are possible.

TC3/4......shaft-TC,
HPI Pro3, Losi JX2R.....2 belt with in-line motor
team magic E4....3 belt, in-line moter
Losi XXX-S, KX1...single belt

Why would you want those old designs? I bet you have a rotary dial cell phone too!


There is a good reason why those designs have been improved over time. Results matter...

Has anyone looked at the Awesomatix Touring car http://www.redrc.net/2009/03/awesoma...ng-car-photos/ I like the idea of really low shocks but how do they work?

The rotary shocks have been around in cars and motorcycle for years. Mostly they have been abandoned due to being overly complex and hard to maintain in full scale applications. Linear dampers are just easier to use and more consistent.

I have no idea about the Awesomatix car. Its winning ETS races in the spec class so it must work ok. I will tell you that based on running its upper arm config on some trinity 1/12th cars I will never run a car with upper arms like that.

Very nice! Have you thought about using saddle packs side by side longitudinally in the same spot as your shortie? The motor would need to move back just a little but it would be even narrower.

Same goes for motors. With BL, they can be smaller than 540-size and still have all the power we ever need. Just the archaic rules getting in the way...

For me, i would like to see more new cars in different style to fit the LIPO+brushless.
A700 is an example for updated shaft TC with some race results in stock ETS.

I am not a motor designer so I have to ask this question. If our current 540 size motors are maxing out with regards to heat for the 25.5 to 10.5 classes how could we make the motors smaller with the same power and not have heat issues?

I know there are different motor designs out there. I have flown electric helis and planes. However, their power requirements are completely different than ours. Drivers require smooth flat powerbands and extremely consistent and linear throttle feel. This is why we run sensored motors. No one has come up with a sensorless system that I am aware of that gives us the drive-ability that we need.

I'm thinking smaller motors couldnt be pushed to the same speeds as we r running now but I'm one of those that thinks even spec racing is still 2 fast ... if mod guys r running9.8 and stock is running 10.4 in indoor tracks I think that's way too close . I'm thinking a 2 sec spread between classes .




motor and battery size specs were to change and give the community a 2yr notice to get ready .
I would be happy with making a change or even being slower running the new tech . But I would have a headstart on feel of the newer stuff by time everyone made the change
